Router Information

For hardware installation and maintenance information about the Cisco XR 12000 Series Router, refer to the installation and configuration guide for your router. This includes information on card slot locations and other general requirements.

Supported Platforms

The PRP is supported on all Cisco XR 12000 Series Router chassis and can be installed in any available slot in any chassis; however PRP-3 is supported only on the Cisco XR 128xx and 124xx Series Router chassis. Also, PRP-1 is only supported on the Cisco 12000 Series Router chassis running Cisco IOS

Software.

PRP Redundancy

When two PRPs are installed in a Cisco XR 12000 Series Router, one PRP is the active PRP and the other is a backup, or standby, PRP. If the active PRP fails or is removed from the system, the standby

PRP detects the failure and initiates a switchover. During a switchover, the standby PRP assumes control of the router, connects with the network interfaces, and activates the local network management interface and system console.

Note If your system includes redundant PRPs, both PRPs should be of the same type (PRP-3 or PRP-2) and have the same memory size. We strongly recommend that you avoid configuring your router using mixed route processor cards.

Cisco IOS XR Software Requirements

For software configuration information, refer to the Cisco IOS XR getting started, configuration, and command reference publications for the installed Cisco IOS XR software release. Refer to the

CiscoIOSR software release notes for additional information.

Note PRP-2 is compatible with Cisco IOS XR Software Release 3.2 or later releases, but PRP-3 is compatible only with Cisco IOS XR Software Release 3.8.0 and later releases. PRP-1 is not supported with any of the Cisco IOS XR Software Releases. PRP-1 is only supported on Cisco IOS Software Releases.

The show version and show hardware commands display the current hardware configuration of the router, including the system software version that is currently loaded and running.

PRP-3 is the next-generation route processor for the Cisco XR 124xx and 128xx Router chassis running

Cisco IOS XR Software Release 3.8.0 or a later release. The PRP-3 is available as product number PRP-3 or PRP-3= for a primary route processor and is available as PRP-3/R for a redundant route processor.

PRP-3 has significant improvements over PRP-2. These improvements include increased speed,

OL-17436-01 3

Product Overview improved scalability, higher system memory, faster packet processing. Because PRP-3 does not support

Cisco IOS Software, the bootflash memory no longer exists in PRP-3. PRP-3 ROMMON has software intelligence to download a Cisco IOS XR image without the support of bootflash memory.

Note PRP-3 supports Cisco XR 124xx (10 G per slot fabric) and Cisco XR 128xx (40 G per slot fabric) Router chassis only. PRP-3 does not support Cisco XR 120xx Router chassis (2.5-G low-speed fabric).

PRP Functions

The PRP-2 provides the following additional functions:

• One IEEE 802.3 10/100/1000-megabits-per-second (Mbps) Ethernet port.

• Two building integrated timing system (BITS) ports for connecting to an external clock source.

Note BITS functionality is currently not supported.

In addition to the functionality listed for the PRP-1 and PRP-2, PRP-3 provides the following specific functions:

•

•

Reduced boot time.

Increased overall scalability.

•

•

•

•

•

•

Improved memory access rates and scale.

Improved CPU performance through dual 1.3-GHz PPC processor cores.

Cisco IOS Software Storage

The Cisco IOS Software images are stored in flash memory. Two types of flash memory ship with the

PRP-1:

•

•

Onboard flash memory—Ships as a single in-line memory module (SIMM). This flash memory contains the Cisco IOS boot image (bootflash) and is not field replaceable.

Flash disk—The PRP ships with an ATA Flash disk that can be installed in either CompactFlash disk slot. The CompactFlash disk contains the Cisco IOS software image. Linear flash memory cards are also supported in the PRP-1.

The PRP-2 provides the following additional flash memory:

• CompactFlash (CF) disk—Optional 1-GB CF disk can be used for large Cisco IOS images.

Storing the Cisco IOS images in flash memory enables you to download and boot from upgraded

Cisco IOS software images remotely, or from software images that reside in PRP flash memory.

Cisco 12000 Series Internet Routers support downloadable system software for most Cisco IOS Software upgrades. This enables you to remotely download, store, and boot from a new Cisco IOS software image.

The Cisco IOS software runs from within the SDRAM of the PRP.

Cisco IOS XR Software Storage

The PRP-3 provides the following compact flash memory for storing the Cisco IOS XR software image:

• Internal CompactFlash (CF) on board—(compact flash:) 2-GB internal compactflash is used for large Cisco IOS XR software images.

• External CompactFlash (CF)—(disk0:) 2-GB external compactflash is used for large Cisco IOS XR software images. The external CompactFlash can be inserted from the front panel of PRP-3.

External CompactFlash replaces the PCMCIA slots of PRP-2.

Storing the Cisco IOS XR images in flash memory enables you to download and boot from upgraded

Cisco IOS XR software images remotely, or from software images that reside in PRP-3 flash memory.

PRP-3 ROMMON Changes

The PRP-3 ROMMON in Cisco IOS XR Software Release 3.8.0 has significant changes and more software intelligence than the PRP-2 ROMMON of previous releases. The following sections discuss in detail the changes introduced in PRP-3 ROMMON.

•

Capability of ROM Monitor to Netboot

•

•

FAT32 File System Support

ROMMON Logical Divisions

Capability of ROM Monitor to Netboot

ROMMON is the initial program that loads in Cisco IOS XR software. It loads the mini.vm file into the

RAM, sets up some initial hardware needed, and then hands over control to the CPU. The CPU thereafter takes on and loads the Cisco IOS XR software to enable the router to come up. The ROMMON in PRP-3 is now more intelligent than the ROMMON in PRP-1 or PRP-2. The ROMMON of PRP-1 and PRP-2 needed a boothelper image to reach TFTP and download the Cisco IOS XR software image. The boothelper image is stored in bootflash. The PRP-3 ROMMON has more software intelligence, because it can reach the TFTP server without a boothelper image. PRP-3 ROMMON does not require a boothelper image to reach the TFTP server. Hence, bootflash memory is also removed from PRP-3.

FAT32 File System Support

PRP-3 ROMMON supports only the FAT32 file system (FS), it does not support FAT12 or FAT16 file system. PRP-3 ROMMON does the native TFTP netboot and file download over the management ports.

ROMMON Logical Divisions

The PRP-3 ROMMON is split into following three software divisions:

•

•

•

Boot Strap Loader (BSL)—BSL thin bootstrap starts one of the two ROMMON images (latest or golden ROMMON images).

Latest ROMMON image—It is the Primary ROMMON image, which sets up the initial hardware.

Golden ROMMON image—It serves as a backup ROMMON image, which is used only if the latest

ROMMON image fails to load from upgrade, corruption, or any other issues.

ROMMON Procedure to Boot an Image from TFTP

The following section discusses booting a Cisco IOS XR software image from TFTP using ROMMON.

Certain changes are related to booting from ROMMON.

Before starting to boot an image from TFTP using ROMMON, ROMMON must be initialized. The output displayed when ROMMON is initialized is displayed below. The output in blue shows the hardware changes in Cisco IOS XR Software Release 3.8.0.

• One auxiliary port (AUX) and one console port (CONSOLE) LED:

–

–

AUX—Used as a backup for the command outputs on the Console.

CONSOLE—Used for configuring the router by connecting an RJ-45 cable to the console terminal. The router can be configured through the console terminal.

Display LEDs

The alphanumeric display LEDs are organized as two rows of four characters each and are located at one end of the card. These LEDs provide system status and error messages that are displayed during and after the boot process. The boot process and the content displayed are controlled by the MBus module software of the PRP.

At the end of the boot process, the LEDs are controlled by the Cisco IOS software (via the MBus), and the content displayed is designated by the Cisco IOS software.

OL-17436-01 15


A complete, descriptive list of all system and error messages is located in the Cisco IOS System Error

Messages publications.

The display LEDs indicate the following:

• Status of the PRP

•

•

System error messages

User-defined status/error messages

Soft Reset Switch

A soft reset switch provides a reset to the processor software on the PRP. You access the soft reset switch through a small opening in the PRP faceplate. To depress the switch, insert a paper clip or a similar object into the opening.

Caution The soft reset switch is not a mechanism for resetting the PRP and reloading the IOS image. It is intended for software development use. To prevent system problems or loss of data, use the soft reset switch only on the advice of Cisco service personnel.

Flash Disk Slots

The PRP includes two Flash disk slots on the front panel of the card. Either slot on the PRP-1 can support an ATA Flash disk or a linear Flash memory card. The Flash disk slots on the PRP-2 can only support

ATA Flash disks.

Note The PRP only supports +5 VDC Flash disk devices. It does not support +3.3 VDC Flash disk devices.

All combinations of different Flash devices are supported by the PRP-1. You can use ATA Flash disks, linear Flash memory cards, or a combination of the two.

Each Flash disk slot has an ejector button for ejecting a card from the slot. See the

“Using Flash Disks in the PRP” section on page 67 for more information.

Note Linear Flash memory cards may not have the capacity to meet the requirements of your configuration.

However, they can be used for emergency file recovery applications.

Asynchronous Serial Ports

The PRP has two asynchronous serial ports, the console and auxiliary ports. These allow you to connect external serial devices to monitor and manage the system. Both ports use RJ-45 receptacles.

The console port provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal. The auxiliary port provides a data terminal equipment (DTE) interface and supports flow control. It is often used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.

Preparing for Installation

Ethernet Ports

The PRP includes two 10/100 Mbps Ethernet ports, each using an 8-pin RJ-45 receptacle for either IEEE

802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps) connections.

The PRP-2 includes a 10/100/1000 Mbps Ethernet port, which uses the above connections and also a

802.3 Gigabit Ethernet connection.

The PRP-3 includes two 10/100/1000 Mbps Ethernet port, which also uses the above connections and also a 802.3 Gigabit Ethernet connection.

Note The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.

Hard Disk Drive

The PRP-2 optionally includes a 40-GB hard disk drive (HDD) that is installed on the PRP-2 board.

The PRP-3 provides an 80-GB hard disk drive (HDD) that is installed on the PRP-3 board.

Note Hard disk drives that are not from Cisco are not supported.

CompactFlash Disk

The PRP-2 optionally includes a 1-GB CompactFlash disk that is installed on the PRP-2 board.

Warning PRP-2 and PRP-3 compactflashes are not compatible with each other and hence PRP-2 compactflash cannot be used in PRP-3 and vice versa. PRP-3 uses Multiword DMA to access the compactflash device, a PRP-2 compactflash does not support this access type.

The PRP-3 board includes a default 2-GB internal CompactFlash and a 2-GB external compact flash. In

PRP-3, the external compact flash replaces the PCMCIA slots of PRP-2.

Note CompactFlash that are not from Cisco are not supported.

Safety Guidelines

Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.

The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.

Note Review the safety warnings listed in the Regulatory Compliance and Safety Information for

Cisco 12000 Series Internet Router publication (Document Number 78-4347-xx) that accompanied your router before installing, configuring, or maintaining a line card.

•

•

•

•

Keep the work area clear and dust free during and after installation. Do not allow dirt or debris to enter into any laser-based components.

Do not wear loose clothing, jewelry, or other items that could get caught in the router while working with line cards.

Cisco equipment operates safely when it is used in accordance with its specifications and product usage instructions.

If you plan to replace a PRP, back up your current configuration file to a remote server or to Flash memory before you remove the PRP. This prevents you from having to reenter all your current configuration information manually. To back up the file, copy your configuration file to a Flash disk or access a remote server.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI) shielding is an integral component of the line card. We recommend using an ESD-preventive strap whenever you are handling network equipment or one of its components.

The following are guidelines for preventing ESD damage:

•

•

Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.

Connect the equipment end of the connection cord to an ESD connection socket on the router or to bare metal on the chassis.

Handle PRPs by the captive installation screws, the provided handle, ejector levers, or the line card metal carrier only; avoid touching the board or connector pins.

•

•

Place removed PRPs board-side-up on an antistatic surface or in a static shielding bag. If you plan to return the component to the factory, immediately place it in a static shielding bag.

Avoid contact between the PRPs and clothing. The wrist strap protects the board from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

Warning For safety, periodically check the resistance value of the ESD strap. The measurement should be between 1 and 10 megohms.

18 OL-17436-01

Removing and Installing a PRP

Required Tools and Equipment

You need the following tools and parts to remove and install a PRP:

• Flat-blade or Phillips screwdriver

•

•

ESD-preventive wrist strap and instructions

Antistatic mat, foam pad, or bag for the removed PRP. Place the removed PRP into an antistatic bag if you plan to return it to the factory, or on an antistatic mat or foam if you are replacing components and will reinstall the PRP.

Working with Electrical Equipment

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedure requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.

•

•

Disconnect all power and external cables before moving a chassis.

Do not work alone when potentially hazardous conditions exist; never assume that power has been disconnected from a circuit; always check.

•

•

Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.


The following sections describe the procedures for removing and installing a PRP as well as removing and installing other field-replaceable hardware on the PRP-2 board. Before beginning the procedures, verify that your system meets the minimum requirements as described in the

“Preparing for Installation” section on page 17

.

•

•

Removing a PRP, page 20

Installing a PRP, page 22

Note The procedures in the following sections use illustrations of a Cisco 12404 Internet Router to support the descriptions of installing and removing a route processor card. The card cages of Cisco XR 12000

Series Routers differ in many ways. However, the process of installing and removing a route processor card are basically the same across the entire chassis line. Therefore, separate procedures and illustrations for each chassis are not included in this publication.

Caution We recommend that you do not remove a PRP while the system is operating. Doing so causes the system to stop forwarding packets and might cause the system to cease network operation. If you are upgrading your router from a GRP to a PRP, you must first power down the router and then switch out the RP cards.

We strongly recommends that you avoid configuring your router using mixed RP cards. If RP redundancy is desired, you must install two PRPs.

OL-17436-01 19


Note You must remove the PRP-2 before you can install or remove the compact flash disk or the hard disk drive. See the

“Additional Configuration and Maintenance Tasks” section on page 59 for more

information.

Removing a PRP

When you remove a PRP from a slot, be sure to use the ejector levers, which help to ensure that the PRP is fully dislodged from the backplane connector. A PRP that is only partially removed from the backplane can halt the system. (See

Figure 7 .)

Caution Before you replace the PRP, back up the running configuration to a TFTP server or a Flash disk so that you can retrieve it later. If the configuration is not saved, it will be lost and you will have to reenter the entire configuration manually. This procedure is not necessary if you are temporarily removing a PRP; lithium batteries will retain the configuration in memory until you replace the PRP in the system.

To remove a PRP, follow these steps:

Step 1

Step 2

Step 3

If you are replacing the PRP in a system with only one PRP, copy the currently running configuration file to a TFTP server or to a Flash disk so that you can retrieve it later.

Turn off system power.

Attach an ESD-preventive wrist strap and follow its instructions for use.

21


Step 4

Step 5

Step 6

Step 7

If you are replacing a PRP, disconnect any devices that are attached to the Ethernet, console, or auxiliary ports. If you are removing a PRP for maintenance and will reinstall the same one, you can leave the devices attached, provided that doing so will not strain the cables.

Using a 3/16-inch flat-blade screwdriver, loosen the two captive screws on the ends of the PRP.

Place your thumbs on the ends of each of the ejector levers and simultaneously pull them both away from the PRP faceplate (in the direction shown in

Figure 7

a) to release the PRP from the upper card cage slot and to dislodge the PRP edge connector from the backplane.

Grasp the PRP faceplate handle with one hand and pull the PRP straight out of the slot, keeping your other hand under the PRP to guide it. Keep the PRP edge connector parallel to the backplane.

Caution Avoid touching the PRP printed circuit board, components, or any edge connector pins.

Step 8 Place the removed PRP on an antistatic mat or foam. If you plan to return the PRP to the factory, immediately place it in an antistatic bag to prevent ESD damage.

Installing a PRP

When you install a PRP, be sure to use the ejector levers, which help to ensure that the PRP is fully

inserted in the backplane connector. (See Figure 7

.) When you push the ejector levers simultaneously inward (toward the center of the PRP), the ejector levers push the PRP into the slot and ensure that the

PRP backplane connector is fully seated in the backplane.

Caution A PRP that is only partially connected to the backplane can halt the system.

To install a PRP, follow these steps:

Step 1

Step 2

Step 3

Turn off system power.

Attach an ESD-preventive wrist strap and follow its instructions for use.

Grasp the PRP faceplate handle with one hand and place your other hand under the carrier to support and guide it into an upper card cage slot.

Caution Avoid touching the PRP printed circuit board, components, or any edge connector pins.

Step 4

Step 5

Step 6

Step 7

Place the bus-connector edge of the PRP in the appropriate slot and align the notches along the edge of the carrier with the grooves at the top and bottom of the slot.

While keeping the PRP edge connector parallel to the backplane, carefully slide the carrier into the slot until the PRP faceplate makes contact with the ejector levers, then stop.

Using the thumb and forefinger of each hand to pinch each ejector lever, push both ejectors simultaneously toward the center of the PRP faceplate until they are perpendicular to the PRP faceplate.

(See

Figure 7

b.)

Using a 3/16-inch flat-blade screwdriver, tighten the captive screws on the ends of the PRP. The captive screws prevent the PRP from becoming partially dislodged from the backplane and ensure proper EMI shielding. (These captive screws must be tightened to meet EMI specifications.)

22 OL-17436-01

Checking the Installation

Step 8

Step 9

Step 10

Step 11

If you disconnected cables to remove the PRP, or if you are installing a new PRP, reconnect the cables to the appropriate ports. (See the

“Checking the Installation” section on page 23 .)

Ensure that the console terminal is turned on.

Turn on system power.

Attach the network end of your RJ-45 cable to your transceiver, switch, hub, repeater, DTE, or other external equipment. Be sure to use the appropriate strain relief on cable connections.


This section assists you in confirming that the PRP is installed successfully and includes the following sections:

•

PRP Boot Process, page 23

•

•

Starting the System and Observing Initial Conditions, page 23

Verifying Interface Status, page 30

PRP Boot Process

The following sequence describes a typical PRP boot process:

1.

System power is turned on.

2.

3.

MBus module receives +5 VDC and starts executing MBus software.

PRP determines the system configuration by sending a message over the MBus requesting all installed devices to identify themselves. The return response provides slot number, and card and component type. The PRP, line cards, and clock scheduler cards (CSCs) are then powered up.

4.

5.

6.

PRP power-on-reset logic delay, which allows power and both local and CSC clocks to stabilize.

After the power-on reset is released, the PRP begins to execute the ROM monitor software.

If the ROM monitor is configured to autoboot, it loads and boots the Cisco IOS software. or

7.

If the ROM monitor is not configured to autoboot, you must enter the appropriate b command at the

ROM monitor prompt ( Rommon> ) to boot the Cisco IOS software.

When the Cisco IOS software boots, it polls all other cards in the system and powers them up, loading their Cisco IOS software as needed.

Starting the System and Observing Initial Conditions

This section describes the initial system startup processes and procedures.

To start your system, follow these steps:

Step 1 Turn on each installed power supply by turning its system power switch to the on (|) position.

OL-17436-01 23


Step 2

Step 3

For AC-input power supplies, the green AC OK LED should go on. For DC-input power supplies, the green input OK LED should go on. For both types of power supplies, the output fail LED should be off.

Listen for the system blower modules or fan trays in the router; you should immediately hear them operating. In a noisy environment, place your hand in front of the exhaust vents to verify that the blower modules are operating.

During the PRP boot process, observe the PRP alphanumeric display LEDs, which are located at one end of the PRP, near the ejector lever. (See

Figure 8 .)

The 4-digit displays show system messages and displays a sequence similar to that shown in

Table 6 .

Step 4 During the line card boot process, which occurs immediately after the PRP boots, observe the alphanumeric display LEDs on each line card.

The system attempts to boot identical line cards in parallel. Furthermore, the system boots line cards as soon as they are powered on and become available for a system boot. The physical location of the alphanumeric display LEDs on the line cards is the same as on the PRP, which is shown in

Figure 8

.

See the appropriate line card installation and configuration note for complete details on line card display

LED sequences.

You must meet the following criteria to successfully boot the PRP:

• Flash disk is installed in Flash disk slot 0

•

•

Flash disk contains a valid Cisco IOS software image

Software configuration register is set to 0x2102

The system automatically boots this Cisco IOS software image. The system then enters the setup facility, where you are prompted to perform a basic configuration of the system.

Otherwise, the system enters the ROM monitor and the appropriate prompt appears (

Rommon>

).

28 OL-17436-01

OL-17436-01


Step 5 If the ROM monitor prompt (

Rommon>

) appears, you must boot the Cisco IOS software image you want to use by entering the appropriate b command at the ROM monitor prompt:

•

•

•

b—Boots the default system software from onboard Flash memory

(if it is present in onboard Flash memory)

b filename [host]—Boots the file filename from the server host using TFTP

b flash—Boots the first file in the Flash memory card in Flash card slot 0

Caution To prevent system problems, use the b flash command option carefully; otherwise, you might instruct the system to boot a non-Cisco IOS software image from Flash memory. This command is not used with

Flash disks.

•

•

•

•

b slot0: filename—Boots the file filename from the Flash memory card in Flash card slot 0

b slot1: filename—Boots the file filename from the Flash memory card in Flash card slot 1

b flash disk0: filename—Boots the file filename from the Flash disk in Flash card slot 0

b flash disk1: filename—Boots the file filename from the Flash disk in Flash card slot 1

Caution The b flash disk0: and b flash disk1: commands are only used from the ROM monitor (

Rommon>

) prompt if the system fails to load normally. Do not use these commands from the router (

Router>

) prompt.

Step 6

Step 7

While the system boots, the console screen displays a script and system banner similar to the following:

Cisco Internetwork Operating System Software

IOS (tm) GS Software (PRP-P-MZ), Released Version 12.0(22)S


Compiled Sat 10-May-02 06:02a

Observe the system startup banner. When you start up an unconfigured system for the first time, the system automatically enters the setup facility, which determines which interfaces are installed and prompts you for configuration information for each one.

On the console screen, after the system displays the system banner and hardware configuration, the following System Configuration Dialog prompt appears:

--- System Configuration Dialog ---

At any point you may enter a question mark '?' for help.

Use ctrl-c to abort configuration dialog at any prompt.

Default settings are in square brackets '[]'.

Continue with configuration dialog? [yes/no]:

You can either proceed with the setup facility or exit from setup and use configuration commands to configure global (system-wide) and interface-specific parameters.

You do not have to configure the interfaces immediately; however, you cannot enable the interfaces or connect them to any networks until they are configured.

The interface-specific LEDs on line cards might not go on until after you configure the line card interfaces. To verify correct operation of each interface, complete the first-time setup procedures and configuration, then refer to the LED descriptions in the configuration notes for each line card to check the status of the interfaces.

29


Verifying Interface Status

The status LEDs on the PRP indicate system and PRP status, which Flash disk slot is active, which

Ethernet connection is in use, and what is occurring on the Ethernet interface. This section provides functional descriptions of the status LEDs on the PRP-2 (

Figure 9 ) and the processes you should

observe.

Upgrading from PRP-1 OR PRP-2 to PRP-3, page 38

Upgrading to the PRP Without Rebooting the Router

To upgrade to the PRP from the GRP without interruption of service, you must have support for High

Availability in your router. This means that two GRPs must be installed in the router and the redundancy must be set to either SSO or RPR+ mode. To configure the redundancy, use the redundancy command in global configuration mode. To view the redundancy configuration on the RPs, use the show

redundancy command.

To upgrade to the PRP using High Availability, use the following procedure:

Step 1 Verify that there are two GRPs in the router, both running the same Cisco IOS version, and that the router is configured for SSO or RPR+ redundancy. The show redundancy command indicates the redundancy mode as well as the Cisco IOS version running on the GRPs. Take note of the Cisco IOS version running on the GRPs (12.0(26)S in this example).

Remove the Flash disk from the PRP card and install it into slot 1 of the active RP. The following message will be displayed; do not format the disk.

22:21:31: %PCMCIAFS-5-DIBERR: PCMCIA disk 1 is formatted from a different router or PC. A format in this router is required before an image can be booted from this device

Note If your router is running an image prior to Cisco IOS Release 12.0(25)S2, you are advised to insert the Flash disk into slot 1 of the standby RP, and not the active RP.

Step 3

Step 4

Verify the disk contents using the dir disk1: command (or the dir stby-disk1: command if the Flash disk is in the standby RP).

Router# dir disk1:

Directory of disk1:/

1 -rw- 17329392 Dec 3 2003 11:44:46 +00:00 c12kprp-p-mz.120-27.S

63832064 bytes total (46465024 bytes free)

If the Cisco IOS version is not the same as the one running on the GRPs, delete the image from the disk using the delete disk1: filename command (or the delete stby-disk1:filename command if the Flash disk is in the standby RP). If the image is correct, continue with

Step 7 .

Note Before you delete the image, verify that you have a copy of this image on another disk or at another location.

32 OL-17436-01


Step 5 Use the copy tftp: disk1: command to copy onto the Flash disk a PRP image that is the same as that currently running on the GRPs (in this example, 12.0(26)S). PRP images are titled c12kprp-<feature set>-<compression>.120-<release id>. You will receive an error that the PRP image is not executable on the GRP. When prompted to abort the copy, type n.

Use the copy tftp: stby-disk1: command if the Flash disk is in the standby RP.

Router# copy tftp: disk1:

Address or name of remote host [172.16.16.254]?

%Warning: File not a valid executable for this system

Abort Copy? [confirm] n

Step 6

Step 7

Step 8

Step 9

Step 10

Step 11

To verify that the image has been copied correctly, verify the MD5 hash for the new image on disk1:. To do this, use the command verify /md5 disk1image-name. The resulting string should be compared against the MD5 hash value posted on the Software download page on Cisco.com.

Place the Flash disk referred to in

Step 5 back into the PRP Flash disk drive.

Repeat Step 2

through

Step 7 for the second PRP to be installed as standby.

Remove any existing boot system commands from the running configuration by using the command no

boot system. This will make the PRP boot from the image on the Flash disk.

Remove the standby GRP from the router.

Insert the PRP into the router in place of the standby GRP. The PRP will now begin to load the Cisco IOS image contained on the Flash disk. At this stage, even though a GRP and a PRP are in the chassis simultaneously, the router remains in SSO or RPR+ mode because the RPs are running the same image.

Note The PRP and GRP must both be running the same Cisco IOS version; otherwise, the redundancy will revert to RPR mode and there may be traffic disruption.

Step 12

Step 13

Remove the active GRP. Because the router is configured for High Availability (SSO or RPR+ mode), the switchover to the PRP will take advantage of the High Availability feature and there will be minimum disruption in operation.

Insert the standby PRP into the chassis, also with the same Cisco IOS image loaded onto its Flash disk.

Now both PRPs will be up and running the same image that was originally running on the GRPs. At this point you can upgrade the Cisco IOS version on the PRPs to the version shipped with the cards.

Note You must have the same Cisco IOS image loaded on the Flash disks of the two PRPs. If different versions are loaded, the redundancy will revert to RPR and there may be traffic disruption.

OL-17436-01

Note If a GRP and PRP are running simultaneously in the router chassis and the PRP is active and the GRP standby, the router will revert to RPR redundancy mode. This is because the upgrade from GRP to PRP is supported with High Availability, but not the downgrade from PRP to GRP.

After you enter the configuration to load the new Cisco IOS software image, you must upgrade the RP

ROM monitor. Follow the appropriate procedure, depending on which version of Cisco IOS software is currently running on the RP.

Upgrading the RP ROM Monitor Using Cisco IOS Release 12.0(24)S or Later, page 34

Upgrading the RP ROM Monitor Prior to Cisco IOS Release 12.0(24)S, page 35

Note The PRP-2 does not require an RP ROM monitor upgrade before Cisco IOS Software Release 12.0(30)S.

If you attempt this upgrade on a PRP-2 using a prior software release, you will receive the following error message:

Error: Unknown Flash Device type!

GRP ROM monitor upgrade won't continue

Upgrading the RP ROM Monitor Using Cisco IOS Release 12.0(24)S or Later

New functionality was introduced in Cisco IOS Software Release 12.0(24)S that enables the secondary

RP to have its ROM monitor image upgraded while in standby mode, and does not require a reboot of the router. In order for this to work, the router must already be running Cisco IOS Software Release

12.0(24)S or later.

In the following procedure, RP1 is initially the active RP and RP2 is the standby RP.

Step 1

Step 2

Step 3

Step 4

Step 5

Step 6

Step 7

After you enter the configuration to load the new Cisco IOS software image, reload the standby PRP

(RP2) using the hw-module standby reload command.

Once the standby RP (RP2) is available again, use the upgrade rom-monitor slot sec-rp-slot command.

If the routine finds that an upgrade is necessary, the new code will begin to be loaded. When this command is completed, reload the RP2 using the hw-module standby reload command.

Switch over from the active PRP (RP1) to the standby PRP (RP2) using the redundancy

force-switchover command. Once RP2 becomes active, the line cards will be reloaded.

Let the router return to full operation with Interior Gateway Protocol (IGP) and Exterior Gateway

Protocol (EGP) peers established (this may take a considerable amount of time, depending on the size and complexity of the router configuration).

Check the line card CPU utilization using the execute-on all show proc cpu | inc CPU command. If the

CPU utilization has stabilized at the normal running level, proceed with the next step; otherwise, wait another five minutes and check again.

Upgrade the Mbus-agent-rom using the upgrade mbus-agent-rom all command. Normal forwarding operation of the line cards will not be affected during the upgrade. The line cards do not need to be reloaded. If any error messages are displayed (see following example), repeat this step before contacting

Cisco TAC.

MBus agent ROM upgrade failed on slot 7 (rc=5)


Use the show version command. If there is an error message at the bottom of the output indicating that a Fabric-downloader code upgrade is required, use the upgrade fabric-downloader all command.

Normal forwarding operation of the line cards will not be affected during the upgrade. The line cards do not need to be reloaded. If any error messages are displayed (see following example), repeat this step before contacting Cisco TAC.

Fabric-downloader upgrade failed on slot 7 (rc=5)


34 OL-17436-01


Step 8 Upgrade the ROM monitor image in RP1 using the upgrade rom-monitor slot sec-rp-slot command. If the routine finds that an upgrade is necessary, the new code will begin to be loaded. Once complete, reload the standby RP using the hw-module standby reload command.

Upgrading the RP ROM Monitor Prior to Cisco IOS Release 12.0(24)S

If your RPs are running a software image prior to Cisco IOS Release 12.0(24)S, you must use the following procedure to upgrade the RP ROM monitor, which requires a reboot of the router.

In the following procedure, RP1 is initially the active RP and RP2 is the standby RP.

Step 3

Step 4

Step 5

Step 6

Step 7

Step 8

After you enter the configuration to load the new Cisco IOS software image, reload the standby PRP

(RP2) using the hw-module standby reload command.

Switch over from the active PRP (RP1) to the standby PRP (RP2) using the redundancy

force-switchover command. Once RP2 becomes active, the line cards will be reloaded.

As soon as the “Press RETURN to get started!” message appears on the console, enter enable mode and use the upgrade rom-monitor slot rp-slot command. If the routine finds that an upgrade is necessary, the new code will begin to be loaded. The router will reload once the ROM monitor upgrade has completed.

RP1 will now be active. As soon as the “Press RETURN to get started!” message appears on the console, enter enable mode and use the upgrade rom-monitor slot rp-slot command. If the routine finds that an upgrade is necessary, the new code will begin to be loaded. The router will reload once the ROM monitor upgrade has completed.

RP2 will be primary now. Let the router return to full operation with IGP and EGP peers established (this may take a considerable amount of time, depending on the size and complexity of the router configuration).

Check the line card CPU utilization using the execute-on all show proc cpu | inc CPU command. If the

CPU utilization has stabilized at the normal running level, proceed with the next step; otherwise, wait another five minutes and check again.

Upgrade the Mbus-agent-rom using the upgrade mbus-agent-rom all command. Normal forwarding operation of the line cards will not be affected during the upgrade. The line cards do not need to be reloaded. If any error messages are displayed (see following example), repeat this step before contacting

Cisco TAC.



Use the show version command. If there is an error message at the bottom of the output indicating that a Fabric-downloader code upgrade is required, use the upgrade fabric-downloader all command.

Normal forwarding operation of the line cards will not be affected during the upgrade. The line cards do not need to be reloaded. If any error messages are displayed (see following example), repeat this step before contacting Cisco TAC.

Upgrading to the PRP With Rebooting the Router

If for any reason you cannot use High Availability, you should use the following procedure to upgrade from a GRP to a PRP.

Step 1

Step 2

Step 3

Step 4

Step 5

Step 6

Step 7

Step 8

Step 9

Remove the Flash disk from the PRP card and install it into slot 1 of the active GRP. The following message will be displayed; do not format the disk.

22:21:31: %PCMCIAFS-5-DIBERR: PCMCIA disk 1 is formatted from a different router or PC. A format in this router is required before an image can be booted from this device

Verify the disk contents using the dir disk1: command.

Router# dir disk1:

63832064 bytes total (46465024 bytes free)

If the Cisco IOS version is not the one you need, delete the image from the disk using the delete disk1:

filename command. If the image is correct, continue with

Step 6 .

Use the copy tftp: disk1: command to copy onto the Flash disk the appropriate PRP image. PRP images are titled c12kprp-<feature set>-<compression>.120-<release id>. You will receive an error that the PRP image is not executable on the GRP. When prompted to abort the copy, type n.

Router# copy tftp: disk1:

Address or name of remote host [172.16.16.254]?

Source filename [c12kprp-boot-mz.120-26.4.S]? c12kprp-p-mz.120-26.4.S

Accessing tftp://172.16.16.254/c12kprp-p-mz.120-26.4.S...

%Warning: File not a valid executable for this system

Abort Copy? [confirm] n

To verify that the image has been copied correctly, verify the MD5 hash for the new image on disk1:. To do this, use the command verify /md5 disk1image-name. The resulting string should be compared against the MD5 hash value posted on the Software download page on Cisco.com.

Remove any existing boot system commands from the running configuration by using the command no

boot system.

Make a note of the image name that is being used on the PRP. You can use the command dir disk1:.

Set the boot system command to boot the new IOS image. Note that the reference will be against disk0:.

This is deliberate. Use the command boot system flash disk0: PRP-image-name.

Save the running configuration to disk1: by using the command copy running-config disk1:

config-name. You can check the configuration by using the command more disk1: config-name.

Note Do not save the configuration on the GRP. In other words, do not type copy running-config

startup-config or write memory. Not saving the configuration ensures that the GRP maintains its original configuration, which will enable you to reinstall the GRP in the future if necessary.

Step 10

Step 11

Step 12

Confirm that disk1 now contains the IOS image and configuration by using the command dir disk1:.

The Cisco IOS image needs to be the first image on the disk.

Turn off the router.

Remove the GRP and insert the PRP in its place.

Step 15

Step 16

Step 17

Connect the Ethernet and console cables to the PRP.

Remove the Flash disk from slot1: on the GRP and insert the Flash disk into slot0: on the PRP.

Boot the router.

The router will come up with no configuration and prompt you to enter the Initial Configuration menu.

Abort the Initial Configuration options by entering no when prompted.

Copy the configuration file which is stored on disk0: to the startup-configuration on the PRP by using the command copy disk0: config-name startup-config.

Note Do not copy the configuration file to the running configuration.

Step 18 Upgrade the Mbus-agent-rom by using the command upgrade mbus-agent-rom all. Line cards do not need to be reloaded. If any error messages are displayed (see following example), repeat this step before contacting Cisco TAC.



Step 19 Upgrade the fabric downloader by using the command upgrade fabric-downloader all. The line cards do not need to be reloaded. If any error messages are displayed (see following example), repeat this step before contacting Cisco TAC.



Step 20 Make a note of which slot the PRP is installed in the chassis. You can use the show gsr command to view this information. In the following example, the RP is located in slot 3.

Router# show gsr

Slot 0 type = 3 Port Gigabit Ethernet

state = IOS RUN Line Card Enabled

Slot 3 type = Route Processor

state = ACTV RP IOS Running ACTIVE

Slot 17 type = Clock Scheduler Card(6) OC-192

state = Card Powered PRIMARY CLOCK

Slot 18 type = Switch Fabric Card(6) OC-192

state = Card Powered





Slot 24 type = Alarm Module(6)


Slot 25 type = Alarm Module(6)


Slot 28 type = Blower Module(6)


Step 21

Step 22

Use the command upgrade rom-monitor slot rp-slot.

If the routine finds that an upgrade is necessary, the new code will be loaded. The router will reload once the rom-monitor upgrade has completed, without saving the running configuration.

If the rom-monitor upgrade was not required, you must now reload the router. If you are prompted to save the system configuration, answer no.

System configuration has been modified. Save? [yes/no]: no

37


Step 23 The router will now boot with the correct configuration as was previously running on the GRP. Perform any post-boot checks: verify that the line cards have booted, required interfaces are active, CEF is operational, IGP adjacencies have formed, and the BGP peerings are established.

Differentiating Between PRP-1 and PRP-2

You can use the software to determine whether you have installed a PRP-1 or a PRP-2. Use the command

show diags prp-slot-number and examine the value in the HW config field. If the value is 0x10, the card is a PRP-2; if the value is 0x00, the card is a PRP-1. The following example is of a PRP-2 (Note bold text in output.):

Turboboot Approach

Pre-Staging Approach

Turboboot Approach

You can upgrade PRP-1 or PRP-2 with Cisco IOS XR software installed to PRP-3 using route processor failover (RPFO). RPFO helps to minimize downtime and ensures service availability. To support RPFO the PRP-1 or PRP-2 must have Cisco IO S XR Software Release 3.8.0 or a later release, which supports

PRP-3. To upgrade PRP-1 or PRP-2 with Cisco IOS XR software to PRP-3 execute the following steps:

Step 1

Step 2

Step 3

Step 4

Step 5

Step 6

Step 7

Step 8

Remove the standby PRP-1 or PRP-2.

Insert PRP-3 in the slot where standby PRP-2 has been removed.

Turboboot PRP-3 with the Cisco IOS XR Software Release 3.8.0 or a later MBI (minimum boot image).

After the standby PRP-3 is ready, perform a route processor fail over (RPFO) from PRP-1 or PRP-2 to

PRP-3.

Double check if the configuration is correct and traffic resumes.

Remove the standby PRP-1 or PRP-2 from the chassis after PRP-3 becomes an active RP.

Insert the secondary PRP-3 board in the chassis.

Turboboot and make the PRP-3 the new standby RP.

OL-17436-01 39


Pre-Staging Approach

In a pre-staging approach the PRP-3 is loaded with the necessary Cisco IOS XR Software Release 3.8.0 software image, optional PIEs, and SMUs in a standalone chassis. After PRP-3 is in working condition, insert into PRP-2 chassis. To upgrade PRP-1 or PRP-2 with Cisco IOS XR software to PRP-3, perform the following steps:

Step 1

Step 2

Step 3

Step 4

Step 5

Step 6

Step 7

Step 8

Turboboot PRP-3 in a standalone chassis.

Install the necessary PIEs, SMUs on the PRP-3.

Remove the standby PRP-2 from the working Cisco XR 12000 Series Router.

Insert the PRP-3 in the slot from where the standby PRP-2 has been removed. PRP-3 will become the standby RP.

Perform RP fail over from PRP-2 to PRP-3 after the RPs are synchronized. The PRP-3 becomes the active RP.

Confirm all the configurations are correct and traffic resumes.

Remove the standby PRP-2.

Insert another PRP-3 to form RP redundancy.

Upgrading GRP or PRP-1 or PRP-2 with Cisco IOS Software to PRP-3

This section discusses upgrading GRP or PRP-1 or PRP-2 with Cisco IOS software installed to PRP-3.

There are two approaches for upgrading PRP-1 or PRP-2 with Cisco IOS software to PRP-3:

•

Turboboot Approach

•

Pre-Staging Approach

Caution The upgrade procedure from Cisco IOS software to Cisco IOS XR software causes service interruption, because the route processor switchover is not supported while upgrading from Cisco IOS software to

Cisco IOS XR software.

Turboboot Approach

The upgrade procedure for GRP or PRP-1 or PRP-2 with Cisco IOS software installed to PRP-3 is same as the basic PRP-3 turboboot upgrade procedure.

Caution The turboboot process causes system downtime.

To upgrade PRP-1 or PRP-2 with Cisco IOS software to PRP-3 execute the following steps:

Step 1

Step 2

Step 3

Step 4

Save the Cisco IOS Software configuration to a secured local computer.

Convert the Cisco IOS Software configuration to Cisco IOS XR software configuration using the URL http://sox.ecsforge.cisco.com/twiki/prod/bin/view/Sox/SoxTryOut

Verify that the converted Cisco IOS XR software configuration has been successfully converted.

Ethernet Interface Receptacles, Cables, and Pinouts

There are two RJ-45 Ethernet interface receptacles on the PRP and one RJ-45 Gigabit Ethernet interface receptacle on the PRP-2, providing media-dependent interface (MDI) Ethernet ports. These connections support IEEE 802.3 and IEEE 802.3u interfaces compliant with 10BASE-T and 100BASE-TX standards.

The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.

Figure 11 shows a PRP RJ-45 receptacle and cable connectors. The RJ-45 connection does not require

an external transceiver. The RJ-45 connection requires Category 5 unshielded twisted-pair (UTP) cables, which are not available from Cisco Systems, but are available from commercial cable vendors.

Table 10

lists the pinout for the RJ-45 receptacle.

Ethernet Interface Cable Connection Procedure

The RJ-45 receptacles on the PRP-1 provide two physical connection options for Ethernet interfaces and three physical connections on the PRP-2. RJ-45 cables are not available from Cisco Systems; they are available from commercial cable vendors. To connect cables to the PRP Ethernet interfaces (ports labeled ETH0, ETH1 and ETH2; see

Figure 9 ), attach the Category 5 UTP cable directly to an RJ-45

receptacle on the PRP.

The Ethernet interfaces on the PRP are end-station devices, not repeaters; therefore, you must connect an Ethernet interface to a repeater or hub.

Note

Only connect cables that comply with EIA/TIA-568 standards. (See Table 11 and Table 12

for cable recommendations and specifications.)

Caution The Ethernet ports are used primarily as Telnet ports into the Cisco XR 12000 Series Router and for booting or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions are switched off by default for security reasons.

We strongly caution you to consider the security implications of switching on CEF routing functions on these ports.

Figure 14 shows an example of the functionality of an Ethernet port. In this example, you cannot access

Network 2.0.0.0 via the Ethernet port (ETH0) on the PRP in Router A; you can only access the hosts and

Router C, which are in Network 1.0.0.0. (See dotted arrows in

Figure 14

.)

To access Network 2.0.0.0 from Router A, you must use an interface port on one of your line cards (in this example, a Packet-over-SONET [POS] line card in Router A) to go through Router B, through

Router C, and into Network 2.0.0.0. (See solid arrows in

Figure 14

.)

Configuring the Ethernet Interfaces

The IEEE 802.3 Ethernet interfaces, located on the PRP, allow connections to external Ethernet networks and are capable of data transmission rates of 10 Mbps and 100 Mbps. The transmission speed of the

Ethernet ports is auto-sensing by default and is user configurable.

Caution An Ethernet port is used primarily as a Telnet port into the Cisco XR 12000 Series Router or for booting or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected.

Cisco Express Forwarding (CEF) functions are switched off by default for security reasons. Cisco strongly cautions you to consider the security implications of switching on CEF routing functions on these ports.

The following sections provide two methods for configuring the Ethernet interface:

•

•

Using Configuration Mode to Configure an Ethernet Interface

Using the Setup Command Facility to Configure an Ethernet Interface

Using Configuration Mode to Configure an Ethernet Interface

To perform a basic configuration of an Ethernet interface in configuration mode, follow these steps:

Step 1

Step 2

Step 3

Step 4

Step 5

Step 6

Step 7

At the privileged-level prompt, enter configuration mode and specify that the console terminal is the source of the configuration subcommands as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

At the configuration mode prompt, specify the Ethernet interface by entering the sub command

interface, followed by the type (ethernet) and port (0) as follows:

Router(config)# interface ethernet 0

Router(config-if)#

If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration sub command, as in the following example:

Router(config-int)# ip address 1.1.1.10 255.255.255.0

Add any additional configuration subcommands required to enable or disable routing protocols (such as the no ip mroute-cache command) and to set other interface characteristics.

Change the shutdown state to Up and enable the Ethernet interface as follows:

Router(config-int)# no shutdown

After you include all the configuration subcommands necessary to complete the configuration, press

Ctrl-Z to exit configuration mode.

Write the new configuration to nonvolatile memory as follows:

Router# write memory

[OK]

Router#

OL-17436-01 45


Using the Setup Command Facility to Configure an Ethernet Interface

In the following example of an Ethernet configuration using the setup command facility, the Ethernet interface is configured using IP and Connectionless Network Service (CLNS). In this example, you should use IP, CLNS, and the default RJ-45 Ethernet connection.

Enter the setup facility using the setup command and respond to prompts as appropriate for your needs, using your own address and mask for the setup prompts.

(Additional displayed text omitted from this example.)

Configuring interface Ethernet0:

Is this interface in use?: yes

Configure IP on this interface?: yes

IP address for this interface: 3.3.1.1

Number of bits in subnet field: 8

Class A network is 3.0.0.0, 8 subnet bits; mask is 255.255.0.0

Configure CLNS on this interface?: yes

Configuring the Console Interface

The system console port on the PRP is a DCE RJ-45 receptacle for connecting a data terminal, which you must configure. The console port is labeled Console, as shown in

Figure 15 . Before connecting the

console port, check the documentation for your terminal to determine the baud rate of the terminal you plan to use.

The baud rate of the terminal must match the default baud rate (9600 baud). Set up the terminal as follows: 9600 baud, 8 data bits, no parity, and 2 stop bits (9600, 8N2). The console port requires a straight-through RJ-45 cable.

Step 4

Step 5

Command or Action

Identify the active RP or DRP.

Purpose

Identifies the RP or DRP to which you must connect in the next step.

•

•

This step is not required when the router hosts only one RP.

On a Cisco CRS-1 router, the active RP or DRP is identified by a lighted Primary LED on the RP front panel.

Connect a terminal to the Console port of the active RP or DRP.

• On a Cisco XR 12000 Series Router, the active RP is identified by the alphanumeric display: ACTV RP.

Establishes a communications path to the router.

•

•

During the initial setup, you can communicate with the router only through the Console port of the active RP.

The router Console port is designed for a serial cable connection to a terminal or a computer that is running a terminal emulation program.

• The terminal settings are:

– Bits per second: 9600/9600

–

–

Data bits: 8

Parity: None

–

–

Stop bit: 2

Flow control: None

Start the terminal emulation program.

(Optional) Prepares a computer for router communications.

Press Enter.

•

•

The step is not required if you are connecting through a terminal.

Terminals send keystrokes to and receive characters from another device. If you connect a computer to the Console port, you must use a terminal emulation program to communicate with the router. For instructions on using the terminal emulation program, see the documentation for that program.

Initiates communication with the router.

• If no text or router prompt appears when you connect to the Console port, press Enter to initiate communications.

•

•

If no text appears when you press Enter and the router has been started recently, give the router more time to complete the initial boot procedure, then press Enter.

If the router has no configuration, the router displays the prompt:

Enter root-system username:


• If the router has been configured, the router displays the prompt:

Username:

Establishes your access rights for the router management session.

• Enter your username and password, as described in the

“Logging In to a Router or an SDR” section on page 52

.

• After you log in, the router displays the CLI prompt, which is described in the

“CLI Prompt” section on page 53

.

OL-17436-01 49


Establishing a Connection Through a Terminal Server

A terminal server connection provides a way to access the Console port from a remote location. It is less expensive to connect to the router through the Management Ethernet interface (because you do not have the additional cost of a terminal server). However, if you need to perform tasks that require Console port access from a remote location, a terminal server is the best connection method.

The procedure for connecting to the router through a terminal server is similar to the procedure for directly connecting through the Console port. For both connection types, the physical connection takes place through the Console port. The difference is that the terminal server connects directly to the Console port, and you must use a Telnet session to establish communications through the terminal server to the router.

To establish a connection through a terminal server, perform the following procedure:

SUMMARY STEPS

Purpose

Prepares the terminal server for communications with the router and with

Telnet clients.

•

•

This step is usually preformed once.

For router access, users need the Telnet server IP address and port number for each RP they access.

• For additional information on configuring terminal services, including terminal servers and templates, see the Cisco IOS XR System

Management Configuration Guide.

Establishes a communications path between the terminal server and the router.

•

•

During the initial router setup, you can communicate with the router only through the Console port of the primary RP.

The router Console port is designed for a serial cable connection to a terminal or terminal server.

• The terminal settings are:

– Bits per second: 9600/9600

–

–

Data bits: 8

Parity: None

–

–

Stop bit: 2

Flow control: None

• To enable terminal server connections to the Console ports on multiple

RPs and DRPs, install a cable between each Console port and the terminal server.

Starts the router.

• This step is required only if the router power is not on.

Identifies the RP or DRP to which you connect in the next step.

• This step is not required when the router hosts only one RP or DRP.

•

•

On a Cisco CRS-1 router, the active RP or DRP is identified by a lighted Primary LED on the RP front panel.

On a Cisco XR 12000 Series Router, the active RP is identified by the alphanumeric display: ACTV RP.

• If you cannot look at the RPs, use a Management Ethernet interface connection to determine which RP is active, or establish terminal server connections to both RPs and then try both.

Establishes a Telnet session with the terminal server.

• Replace access-server-address with the IP address of the terminal server, and replace port with the terminal server port number that connects to the target RP Console port.

OL-17436-01 51


Step 6


Press Enter.

Step 7 Log in to the router.

Purpose

(Optional) Initiates communications with the RP or DRP.

• If no text or router prompt appears when you start the Telnet session, press Enter to initiate communications.

•

•

If the router has no configuration, the router displays the prompt:

Enter root-system username:

Enter the root-system username and password when prompted.

If the router has been configured, the router displays the prompt:

Username:

Establishes your access rights for the router management session.

• Enter a username and password when prompted.

Establishing a Connection Through the Management Ethernet Interface

The Management Ethernet interface allows you to manage the router using a network connection. Before you can use the Management Ethernet interface, the interface must be configured, as described in the

“Configuring the Management Ethernet Interface” section on page 56 .

Once configured, the network connection takes place between client software on a workstation computer and a server process within the router. The type of client software you use depends on the server process you want to use. The Cisco IOS XR software supports the following client and server services:

•

•

Telnet clients can connect to a Telnet server in the router. The Telnet server is disabled by default and can be enabled with the telnet ipv4 server or telnet ipv6 server command in global configuration mode.

Secure Shell (SSH) clients can connect to an SSH server in the router. The SSH server is disabled by default and can be enabled with the ssh server command in global configuration mode. The SSH server handles both Secure Shell Version 1 (SSHv1) and SSHv2 incoming client connections for both IPv4 and IPv6 address families.

To start a Telnet network connection, you start the Telnet client software with a command similar to the following:

telnet ManagementEthernetInterfaceIPaddress

For specific instructions on connecting to the router through a Telnet or SSH client, see the instructions for that software.

Ask your system administrator for the IP address of the Management Ethernet interface.

When the Telnet session is established, the router prompts you to log in, as described in the

“Logging In to a Router or an SDR” section on page 52 .

Logging In to a Router or an SDR

The login process can require users to enter a password or a username and password before accessing the router CLI. The user groups to which your username is assigned determine which commands you can use.

If you log in to a router with a single SDR configured (this is the default configuration), you can manage the entire router. If you log in to the owner SDR on a system with multiple SDRs, you can manage general features that apply to the entire system and the interfaces assigned to the owner SDR. If you log in to a named SDR, you can manage only that SDR.

52 OL-17436-01


When you log in, the username and password may be validated by any of the following services:

•

•

•

Usernames configured on the router (username command in global configuration mode)

Root-system usernames configured on the owner SDR

•

Passwords configured for the router console and auxiliary ports (password or secret command in line configuration mode)

A RADIUS server

• A TACACS+ server

The username and password validation method that your router uses is determined by the router configuration. For information on configuring username and password validation methods, see the

Cisco IOS XR System Security Configuration Guide. For information on which username and password to use, see your system administrator.

To log in to the router, enter your username and password when prompted. For example:

User Access Verification

Username: iosxr

Password: password

RP/0/RP0/CPU0:router#

CLI Prompt

Note Passwords are case sensitive. If you want to log in to an SDR using a root-system username from the owner SDR, enter the username in the following format: username@admin. To support admin login, local database authentication must be enabled with the aaa authentication login remote local command. For more information, see Cisco IOS XR System Security Configuration Guide.

After you log in, the router displays the CLI prompt, which is described in the

“CLI Prompt” section on page 53

. The command set that you can use is determined by the privileges assigned to your username.

For information on how privileges are assigned to usernames, see the Cisco IOS XR System Security

Configuration Guide.

After you log in, you see the CLI prompt for the Cisco IOS XR software. This prompt identifies the router or SDR to which you are issuing commands. The CLI prompt represents the path, through the router, to the CPU that executes the commands you enter. The syntax for the CLI prompt is:

type/rack/slot/module: router-name#. The CLI prompt is described in

Table 15

.

Table 15 CLI Prompt Description

Prompt Syntax Components type rack

Description

Type of interface or card with which you are communicating. For most user communication tasks, the type is “RP.”

Rack number. In a standalone router, the rack number is always “0.”

In a multishelf system, the range for LCC rack numbers is 0 to 255, and the range for FCC rack numbers is F0 to F7.

Description

Slot in which the RP or DRP is installed. In a Cisco CRS-1 router, the

RP physical slot number is “RP0” or “RP1.” In a

Cisco XR 12000 Series Router, the physical slot number can be 0 to

15, and there can be multiple SDRs, each of which is represented by an RP.

Entity on a card that executes user commands or communicates with a port (interface). For executing commands from the EXEC prompt, the module is the “CPU0” of the RP. “CPU0” also controls the forwarding and operating system (OS) functions for the system.

DRPs have two processors: CPU0 and CPU1.

Hostname of the router or SDR. The hostname is usually defined during initial configuration of the router.

For example, the following prompt indicates that the CLI commands are executed on the RP in rack 0, slot RP0, by the “CPU0” module on a router named “router:”


Configuring the Management Ethernet Interface on PRP-3

The Management Ethernet interface on the PRP-3 is used to connect the router to a network for remote management using a Telnet client, the Craft Works Interface (CWI), the Simple Network Management

Protocol (SNMP), or other management agents. The following sections provide information on the

Management Ethernet interface:

Configuring the Management Ethernet Interface

To use the Management Ethernet interface for system management and remote communication, you must configure an IP address and a subnet mask for the interface. If you want the interface to communicate with devices on other networks (such as remote management stations or TFTP servers), you need to configure a default route for the router.

Prerequisites

Tip For information on additional configuration options for the Management Ethernet interface, see

Cisco IOS XR Interface and Hardware Component Configuration Guide.

To configure the Ethernet Management port for network communications, you must enter the interface network addresses and subnet mask. Consult your network administrator or system planner for this information.

Description of the Software Configuration Register

The software configuration register is a 16-bit register in NVRAM that you use to define specific system parameters. You can set or change the contents of this register to accomplish the following tasks:

• Define the source for the default Cisco IOS software. You can specify any of the following:

–

–

Flash memory card inserted in PCMCIA slot 0

TFTP server on the network

•

•

•

•

•

•

–

–

Flash memory SIMM (NVRAM) on the RP

Boot image stored within the operating environment, which you access by using an appropriate form of the boot command entered at the ROM monitor prompt ( rommon>

)

Define a default boot filename.

Enable or disable the Break function.

Control broadcast addresses.

Set the console terminal baud rate.

Recover a lost password.

Force an automatic boot using a boot image.

When you first power on the router, a boot image called the RP ROM monitor is executed, resulting in the display of the ROM monitor prompt (

Rommon>

). At this prompt, you have access to a limited set of commands that enable you to set values in the software configuration register and to perform a number of other tasks.

OL-17436-01 59


The RP ROM monitor is loaded into the RP Flash ROM when the RP is manufactured. You can use it to boot the system from local Flash memory devices. The RP ROM monitor software can be upgraded in the field, if necessary.

Note All PRP-2 cards shipped prior to the release of Cisco IOS release 12.0(30)S are provided with a

ROM monitor version installed at the factory. This ROM monitor version cannot be changed while using IOS images older than 12.0(30)S. When using software release 12.0(30)S or later, the ROM monitor software can be updated normally.

If you attempt to upgrade the ROM monitor software while running a release prior to 12.0(30)S, you will receive the following error message:

Unknown device (mfg id 0x01, dev id 0xA3

Error: Unknown Flash Device type!

GRP ROM monitor upgrade won't continue

If you are running a PRP-2 on a software release prior to 12.0(30)S and you receive an error message that you must upgrade the ROM monitor software, ignore this error message.

• Read boot system commands from the configuration file stored in NVRAM.

OEM = original equipment manufacturer.

Note Valid software configuration register values may be combinations of settings, rather than the individual settings listed in

Table 18 . For example, the factory default value 0x0102 for the software configuration

register is a composite of several settings.

60 OL-17436-01


Boot Field Settings

Bits 00 to 03 of the software configuration register are referred to as the boot field, which defines a source for booting the default Cisco IOS software image required to run the router. The value of the boot field is specified as a binary number, as described in

Table 19

.

Table 19 Definition of Bits in Boot Field of Software Configuration Register

Boot Field Meaning

00 On power up, the system remains at the ROM monitor prompt ( command to boot the system manually.

Rommon>

), awaiting a user

01

02 to 0F

On power up, the system automatically boots the first system image found in the onboard

Flash memory SIMM on the RP.

If a valid boot system command is stored in the NVRAM configuration file, the router boots the Cisco IOS software image as directed by that value.

If no boot system command is present in the configuration file, the router forms a default boot filename and attempts to acquire that file from a network TFTP server. To compute the filename of this default image, the router starts with cisco and appends the octal equivalent of the boot field value, a hyphen, and the processor type (grp or prp).

Table 20

lists the range of possible computed default filenames for booting over the network.

The router would use one of these filenames to boot a default system image stored on a network TFTP server. If the configuration file contains a valid boot system configuration command, the system uses these instructions to boot the system, rather than using the filename it computed from the software configuration register settings.

For this setting, it is assumed that the Ethernet port on the RP is configured and operational.

Note If a bootable Cisco IOS software image exists in a Flash memory card inserted in

PCMCIA slot 0 or slot 1, the software configuration register boot field setting is overridden, and the system boots from the Cisco IOS software image in the Flash memory card, rather than from a network TFTP image.

Note Cisco 12000 Series Internet Routers are typically delivered from the factory with a mini-Cisco IOS software boot image in the boot flash and a flash card containing a suitable working Cisco IOS image.

If you need a Cisco IOS upgrade, download the appropriate Cisco IOS image from Cisco.com.

Configuring the Software Configuration Register

To configure the software configuration register, follow these steps:

Command

Step 1 Router> enable

Password: <password>

Step 2 Router# configure terminal

Step 3 Router(config)# config-register 0xvalue

Purpose

Enters privileged EXEC mode.


Sets the contents of the software configuration register, where value

is a 4-bit hexadecimal number as described in Table 18

.

OL-17436-01 61


Command

Step 4 Router(config)# ctrl-Z

Step 5 Router# show version

Purpose

Exits global configuration mode.

Displays the software configuration register value currently in effect. This is the value that will be used the next time the router reloads. The value is displayed on the last line of the display, as in the following example:

Configuration register is 0x141 (will be 0x102 at next reload)

Saves the software configuration register settings to NVRAM.

Step 6 Router# copy running-config startup-config or

Router# write memory

Step 7 Router# reload Reboots the router. Configuration register changes take effect only after the system reloads.

Bits in the Software Configuration Register

As described in the “Boot Field Settings” section on page 61

, the boot field setting determines the source of the Cisco IOS software image that is used to boot the router. A detailed description of the bit values for the boot field and their associated action or filename is given in

The remaining bits in the software configuration register are described following:

Bit 8 of the software configuration register controls the console Break key. Setting bit 8 causes the system to ignore the console Break key. This is the factory default. Conversely, clearing bit 8 causes the system to interpret a Break keystroke as a command to halt normal system operation and force the system

62 OL-17436-01

Additional Configuration and Maintenance Tasks into ROM monitor mode. Regardless of the setting of the Break enable bit in the software configuration register, pressing the Break key during approximately the first 5 seconds of booting causes a return to the ROM monitor.

Bit 9 is not used.

Bit 10 of the software configuration register controls the host portion of the IP broadcast address. Setting bit 10 causes the processor to use all zeros in the host portion of the IP broadcast address; clearing bit

10 (the factory default) causes the processor to use all ones. Bit 10 interacts with bit 14, which controls the network and subnet portions of the IP broadcast address.

Bits 11 and 12 of the software configuration register determine the data transmission rate of the console

terminal. Table 22 shows the bit settings for the four available data transmission rates. The factory-set

default data transmission rate is 9600 bps.

Bit 13 of the software configuration register determines the response of the system to a bootload failure.

Setting bit 13 causes the system to load Cisco IOS software from Flash memory after five unsuccessful attempts to load a boot file from the network TFTP server. Clearing bit 13 causes the system to continue attempting to load a boot file from the network TFTP server indefinitely. Bit 13 in the software configuration register is set to 0 as the default at the factory.

Understanding the Cisco IOS XR Software Configuration Register

The Cisco IOS XR Software configuration register (config-register) is a 16-bit, user-configurable value that determines how the router functions during initialization. The configuration register can cause the router to boot normally from the default startup configuration, or to enter ROM monitor mode during a system reset. Typically, ROM monitor mode is used only for password recovery or for software maintenance that cannot be performed in Exec mode or global configuration mode.

Using Flash Disks in the PRP

Procedures for using Flash disks in the PRP are presented in the following sections:

Removing and Installing a Flash Disk in the PRP, page 68

Working with Flash Disks, page 70

About Flash Disks

ATA Flash disks are similar to linear Flash memory cards. Flash disks combine Flash memory technology with a controller chip to achieve higher capacity and better performance than linear Flash memory cards. The controller circuitry allows Flash disks to emulate hard disk capabilities, such as automatically mapping out bad blocks and block erasure. Flash disks also provide the capability to allocate noncontiguous sectors, eliminating the need for the squeeze command that is required for space retrieval on linear Flash memory cards.

Flash disks look similar to older Cisco 20-MB linear Flash memory cards. You can install a flash disk into either flash card slot on the PRP.

Table 24

lists the Cisco product numbers for the flash disks that are available for use with Cisco XR 12000 Series Routers.

Installing a Flash Disk

To install a flash disk, follow these steps:

Step 1

Step 2

Remove the flash disk slot cover by loosening the captive screw shown in

Figure 16 .

Facing the PRP front panel, hold the flash disk with the connector end of the card toward the slot and the label facing to your right. (See

Figure 17 .)

Note The Flash disk is keyed and cannot be seated the wrong way. The ejector button will not pop out if the card is not properly inserted.

Step 3

Step 4

Insert the card into the appropriate slot until the card completely seats in the connector at the back of the slot and the ejector button pops out toward you.

Replace the flash disk slot cover.

OL-17436-01 69


Caution The Flash disk does not insert all the way inside the PRP; a portion of the card remains outside of the slot. Do not attempt to force the card past this point.

Working with Flash Disks

A Flash disk contains the Cisco IOS software image you need to boot your router. In some cases, you might need to insert a new Flash disk and copy images or backup configuration files onto it. Before you can use a new Flash disk, you must format it.

When using Cisco IOS commands, there is one major difference between using Flash disks and linear

Flash memory cards: When using a linear Flash memory card, the Cisco IOS command to identify and access the card is slot0: or slot1:, depending on the card slot in use. When using a Flash disk, those commands are replaced with disk0: or disk1:. Other specific Flash disk information is found in the remainder of this section.

Note This publication does not cover all Cisco IOS Flash card commands. For complete Flash card command descriptions and configuration information, refer to the Cisco IOS Configuration Fundamentals

Command Reference and to the Cisco IOS Configuration Fundamentals Configuration Guide.

Booting from a Flash Disk

This section describes the commands used to boot from a Flash disk. Flash disks are accessed using

disk0: or disk1:, depending on the card slot location, instead of slot0: or slot1:, which is used with linear

Flash memory cards.

Note A boot image that supports the ATA Flash disk file system must reside in bootflash.

To enable booting from a Flash disk, set the register bits to 0x2102 and add the boot system command, as follows:


Enter configuration commands, one per line. End with CTRL-Z.

Router(config)# config-reg 0x2102

Router(config)# boot system disk0:c12kprp-p-mz.120-22.S

Router(config)# ^Z

Router# copy running-config startup-config

The boot system command may require a file name when applied to a Flash disk. The format is described in

Table 25 .

Table 25 Boot System Command Format

Router(config)# boot system disk0:filename

1

Router(config)# boot system disk1:filename

1

Boots the named file from the Flash disk in slot 0.

Boots the named file from the Flash disk in slot 1.

1.

Entering a filename is optional. If a filename is not specified, the system attempts to boot the first file located on the

Flash disk.

70 OL-17436-01


Removing and Installing a Compact Flash Disk

Note You must remove the PRP-2 before you can remove or install a compact flash disk. The compact flash disk is only supported on the PRP-2.

To remove a compact flash disk (CF) from the PRP-2 board, follow these steps:

Figure 19

Step 1

Step 2

Step 3

Loosen the screw fastening the retaining bracket for the CF. (See

Figure 19

.)

Lift the end of the retaining bracket out of the hole that holds it in place flush with the CF, and swivel it

around until it is not in the way of removing the CF. (See Figure 19 .)

Press lightly on the CF and push it out of its socket in the direction of the retaining bracket. (See

Figure 19 .)

Removing the CF from the PRP-2 Board

OL-17436-01

Step 5

Once the CF is released from the socket, pull it completely out of the board.

If you are not inserting another CF into the socket on the board, replace the retaining bracket by swivelling it back around until the end rests in the hole on the PRP-2 board and fastening the screw into the board.

To install a CF into the PRP-2 board, follow these steps:

Step 1

Step 2

Step 3

Step 4

Loosen the screw fastening the retaining bracket for the CF.

Lift the end of the retaining bracket out of the hole that holds it in place flush with the CF socket, and swivel it around until it is not in the way of installing the CF.

Guide the CF into the socket with the side with the connectors going into the socket.

Push the CF until it snaps into place in the socket.

71


Step 5

Step 6

Swivel the retaining bracket back into place with the end of the bracket resting in the hole on the PRP-2 board.

Fasten the screw on the retaining bracket.

Removing and Installing a Hard Disk Drive

Note You must remove the PRP-3 or PRP-2 before you can remove or install a hard disk drive. The hard disk drive is only supported on the PRP-2.

To remove a hard disk drive (HDD) from the PRP-3 or PRP-2 board, follow these steps:

Step 1

Step 2

Loosen the four screws fastening the HDD to the board. The screws will pop out of place when they are completely loosened.

Pull the HDD straight up off the board.

To install an HDD onto the PRP-3 or PRP-2 board, follow these steps:

Step 1 Position the HDD over the four screw receptors on the PRP-3 or PRP-2 board so that the two silver guide pins on the board fit into the two associated holes on the HDD (next to two of the screws) and the arrow

printed on the top of the HDD points toward the faceplate of the card. See Figure 20 .

Recovering a Lost Password For IOS

This section provides information on how to recover a lost password.

The following overview describes this process:

1.

Use the show version command to note the existing software configuration register value.

2.

Break to the bootstrap program prompt.

3.

Change the configuration register to ignore NVRAM.

74 OL-17436-01


OL-17436-01

Note A key to recovering a lost password is to set the configuration register so that the contents of NVRAM are ignored (0x0040), allowing you to see your password.

4.

5.

Enter privileged level in the system EXEC.

Use the show startup-config command to display the enable password.

6.

Change the configuration register value back to its original setting.

To recover a lost password, follow these steps:

Note If the enable password is encrypted, the following password recovery procedure will not work and you will have to reconfigure the system; you will not be able to reboot it. To reconfigure the system, use the displayed configuration, which is shown using the show startup-config EXEC command. (See

Step 11

.)

Step 1

Step 2

Step 3

Step 4

Step 5

Step 6

Attach an ASCII terminal to the PRP console port.

Configure the terminal to operate at 9600 bps, 8 data bits, no parity, 2 stop bits (or to the settings at which the console port is set).

Enter the show version command to display the existing configuration register value. Note this value for later use.

If Break is disabled, power cycle the router. (To power cycle, turn off power, wait 5 seconds, then turn it on again.) If Break is enabled on the router, press the Break key or send a break by holding down the

Control key and pressing the right square bracket key (^]); then proceed to Step 5.

Within 5 seconds of turning on the router, press the Break key. This action causes the terminal to display the bootstrap program prompt as follows:

Rommon 1>

Set the configuration register to ignore the configuration file information as follows:

Rommon 1> confreg

Step 13

Step 14

Change the configuration register value back to its original value (noted from

Step 3 .)

Change it to a value of 0x0102 (factory default) using the config-register 0x value command.

Press Ctrl-Z or type end to exit configuration mode.

Reboot the router and enable it using the recovered password.

Recovering Password for IOS XR

If the root password is forgotten, it can be recovered only at the DSC. To recover the password at the

DSC, set the configuration register to 0x42 on the active RP and reboot the router. When the router boots, a password recovery dialog appears. This dialog prompts you to reset the root-system username and password. After you save the new password, the configuration register automatically resets to the prior value (such as 0x102).

This chapter also includes instructions to bypass ksh authentication on a node.

Upgrading PRP Memory

This section provides the procedure for increasing the amount of SDRAM on a PRP by replacing up to two SDRAM DIMMs that reside on the PRP. The SDRAM DIMM sockets are U15 (bank 1) and U18

(bank 2). (See

Figure 22 .)

The default SDRAM configuration for PRP-2 is 1 GB DIMM in U15. If two memory modules of different size are installed, the larger DIMM must be installed in bank 1 (U15).

Note The DIMMs in

Figure 22

and

Figure 26 show a generic representation of the SDRAM DIMMs for your

PRP. To be assured that you are using the correct DIMMs, refer to the specific part numbers for your

SDRAM upgrade kit and to the Cisco part numbers on the DIMMs. (See Table 27

.)

Before proceeding, ensure that you have the proper tools and ESD-prevention equipment available. To upgrade SDRAM, you will install DIMMs in one or two banks (U15 and U18).

Table 27 list the various

available configurations of SDRAM DIMMs, the number of DIMMs for each configuration, and the

SDRAM banks they occupy. Note which banks you should use, given the combinations of available

DIMM sizes and the maximum SDRAM you require.

Note Depending on the configuration of your router and the protocols and features your system is running, you might require more than the default SDRAM provided. Upgrade SDRAM based on your requirements and the information in

Table 27

.)

Removing a DIMM

To remove a DIMM from a line card, follow these steps:

Step 1

Step 2

Step 3

Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Place the line card on an antistatic mat so that the faceplate is nearest to you.

Locate the DIMM sockets on the line card.

Note Some line cards use DIMM sockets equipped with dual release levers, as shown in Figure 24 ; other line cards use DIMM sockets equipped with a single release lever, as shown in Figure 25 .

Both DIMM sockets operate in the same general way.

Figure 24 DIMM Socket with Dual Release Levers

Figure 25 DIMM Socket with Single Release Lever

OL-17436-01 81


Step 4 Use the socket release levers to eject the DIMM.

• For a socket with dual release levers (see the DIMM.

or

Figure 24 ), pull down both levers at the same time to eject

• For a socket with a single release lever (see Figure 25 ), pull the lever to eject the DIMM.

Caution Handle the edges of the DIMM only. Do not touch the integrated circuit devices on the DIMM, the metal traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket.

Step 5

Step 6

Step 7

As one end of the DIMM is released, grasp the top corners of the DIMM with the thumb and forefinger of each hand and pull the DIMM completely out of its socket.

Immediately place the DIMM in an antistatic bag to protect it from ESD damage.

Repeat Step 4 through Step 6 for any remaining DIMMs that you want to remove.

Installing a DIMM

This section contains instructions for installing DIMM memory into a line card.

Note If you are upgrading packet memory, both DIMM sockets of a given pair (either the transmit buffer or the receive buffer) must be populated with a DIMM of the same type and size.

To install DIMMs in a line card, follow these steps:

Step 1

Step 2

Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Place the line card on an antistatic mat so that the faceplate is nearest to you.

Caution To prevent router and memory problems, all DIMMs installed in the line card must be 3.3V devices.

Step 3

Step 4

Step 5

Remove the new DIMM from its protective antistatic bag.

Grasp the edges of the DIMM only. Do not touch the integrated circuit devices on the DIMM, the metal traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket. (See Figure 26 .)

To position the DIMM for insertion, orient it at the same angle as the DIMM socket. The two notches

(keys) on the bottom edge of the module ensure that the DIMM edge connector is registered properly in the socket. (See Figure 26 .)

If necessary, rock the DIMM back and forth gently to align it in the socket.

82 OL-17436-01

Figure 26 Handling a DIMM


Key

Caution When inserting DIMMs into a socket, apply firm, but not excessive, pressure. If you damage a DIMM socket, you must return the line card for repair.

Step 6

Step 7

Step 8

Gently insert the DIMM into the socket and push until the DIMM snaps into place and the release lever is flush against the side of the socket.

Verify that the release lever is flush against the side of the socket. If it is not, the DIMM might not be seated properly. On a socket with dual release levers, both levers should be flush against the sides of the

DIMM.

If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush against the side of the DIMM socket.

Repeat Step 3 through Step 7 to install any remaining DIMMs for your memory configuration.

Checking the DIMM Installation

After you install new DIMMs and replace the PRP in the router, the router reinitializes the PRP and detects the memory change as part of the reinitialization cycle. The time required for the router to initialize can vary with different router configurations and memory configurations.

If the PRP or the system does not reinitialize properly after you upgrade memory, or if the console terminal displays a checksum or memory error, verify the following:

Step 1

Step 2

Check the packet memory DIMMs to verify that the type, size, and speed of the DIMMs are compatible with the PRP. DIMMs must operate at 60 ns or faster. The speed of the DIMM is printed along one of its edges.

Ensure that the DIMMs are installed correctly on the PRP. Check the alignment of the DIMMs by looking at them across the horizontal plane of the card. The DIMMs should be aligned at the same angle and be fully inserted into their respective sockets. If a DIMM is not correctly aligned, remove it and reinsert it.

OL-17436-01 83

Regulatory, Compliance, and Safety Information

Step 3 Reinstall the PRP and perform another installation check.

If the router fails to restart properly after several attempts and you are unable to resolve the problem, access Cisco.com or contact your Cisco service representative for assistance. Before calling, however, make note of any console error messages, unusual LED states, or other router indications or behaviors that might help to resolve the problem.
