Installation Guidelines

Before you install the switch in the Lenovo Flex System chassis, read the following information:



Read the safety information that begins on page 5

,

“Handling Static-Sensitive

Devices” on page 19

, and the safety statements in the Lenovo Flex System chassis documentation. This information provides a safe working environment.

 Observe good housekeeping in the area where you are working. Place removed covers and other parts in a safe place.

 Blue on a component indicates touch points, where you can grip the component to remove it from or install it in the compute node or Lenovo Flex System chassis, open or close a latch, and so on.

 Orange on a component or an orange label on or near a component on the switch, compute node, or Lenovo Flex System chassis indicates that the component can be hot-swapped, which means that if the Lenovo Flex System chassis and operating system support hot-swap capability, you can remove or install the component while the Lenovo Flex System chassis is running. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.

 You do not have to turn off the Lenovo Flex System chassis to install or replace any of the hot-swap modules on the front or rear of the Lenovo Flex System chassis.

 When you install the switch in the Lenovo Flex System chassis, you must also install a compatible I/O network adapter in the compute node to support the switch.

 When you are finished working on the compute node or Lenovo Flex System chassis, reinstall all safety shields, guards, labels, and ground wires.

18


System Reliability Guidelines

To help ensure proper cooling, performance, and system reliability, make sure that the following requirements are met:

 Each of the bays on the rear of the Lenovo Flex System chassis contains either a module or a filler module.

 A removed hot-swap module is replaced with an identical module or filler module within one minute of removal.

 A removed hot-swap compute node is replaced with another compute node or filler node within one minute of removal.

 The ventilation areas on the sides of the compute node are not blocked.

 You have followed the reliability guidelines in the documentation that comes with the Lenovo Flex System chassis.

Handling Static-Sensitive Devices

Attention: Static electricity can damage the switch and other electronic devices. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

 Limit your movement. Movement can cause static electricity to build up around you.

 The use of a grounding system is recommended. For example, wear an electrostatic-discharge wrist strap, if one is available.

 Handle the device carefully, holding it by its edges or its frame.

 Do not touch solder joints, pins, or exposed printed circuitry.

 Do not leave the device where others can handle and damage it.

 While the device is still in its static-protective package, touch it to an unpainted metal part of any unpainted metal surface on a grounded rack component in the rack in which you are installing the device, for at least two seconds. This drains static electricity from the package and from your body.

 Remove the device from its package and install it directly into the switch without setting it down. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on a switch cover or on a metal surface.

 Take additional care when you handle devices during cold weather. Heating reduces indoor humidity and increases static electricity.

 Some types of Lenovo Flex System chassis come with electrostatic discharge

(ESD) connectors. If your unit is equipped with an ESD connector, see the documentation that comes with the Lenovo Flex System chassis for using the

ESD connector.

Installing the CN4093

Note: The following illustration shows how to install the switch in a Lenovo Flex

System chassis. The appearance of your Lenovo Flex System chassis might be different; see the documentation for your Lenovo Flex System chassis for additional information.

Use the following instructions to install the switch in the Lenovo Flex System chassis. You can install the switch while the Lenovo Flex System chassis is powered on. For redundancy support, you must install I/O modules of the same type in I/O bays 1 and 2, and I/O modules of the same type in bays 3 and 4 of the chassis.

To install the switch, complete the following steps.

1. Read the safety information that begins on

page 5 and

“Installation Guidelines” on page 18 .

2. Select I/O bay in which to install the switch.

Note: For details about I/O bay requirements and bay locations, see the documentation for the Lenovo Flex System chassis.

3. Remove the filler module from the selected bay. Store the filler module for future use.

4. If you have not already done so, touch the static-protective package that contains the switch to an unpainted metal surface of the Lenovo Flex System chassis or an

unpainted metal surface on any other grounded rack-component for at least 2 seconds.

5. Remove the switch from its static-protective package.

6. Make sure that the release levers on the switch are in the open position

(perpendicular to the switch).

7. Slide the switch into the applicable I/O bay until it stops.

20


8. Push the release levers on the front of the switch to the closed position. After you insert and lock the switch, it is turned on (there may be a slight delay), and a

Power-On Self-Test (POST) occurs to verify that the switch is operating correctly.

Note: The switch may take up to two minutes to complete the POST. During

POST, the Power LED continuously flashes. Once POST has successfully completed, the Power LED remains on and the Error LED is off.

9. Make sure that LEDs on the switch indicate that it is operating correctly (see

“Information LEDs” on page 34 ).

10. If you have another switch to install, repeat

Step 3 through

Step 9

; otherwise, go to the next step.

11. Install any port transceiver modules or Direct-Attach Cables (DACs) needed for the

switch. For information and instructions, see “Connecting Switch Ports” on page 23 and the documentation that comes with the transceiver modules or DACs.

12. Attach any cables that are required by the switch. For additional information about cabling the switch, see

“Connecting Switch Ports” on page 23 , the documentation

that comes with the port transceiver modules, DACs, cables, and the optional network devices to which the cables are connected.

13. Make sure that the data (non-management) ports on the switch are enabled through the Chassis Management Module (CMM).

Removing or Replacing the Switch

Note: The following illustration shows how to remove and replace the switch from the Lenovo Flex System chassis. The appearance of your Lenovo Flex System chassis might be different; see the documentation for your Lenovo Flex System chassis for additional information.

To replace the switch, complete the following steps.

1. Read the safety information that begins on page 5 , and


2. Detach any cables that are attached to the switch you will be removing.

Note: Detaching cables from the switch ports disrupts the network connection from the switch to any connected external devices. If you plan to replace the switch with another switch, you can reuse the existing cables, provided they remains securely attached to the network.

3. Pull the release latches out from the switch. The switch moves out of the bay approximately 0.6 cm (0.25 inch).

4. Slide the switch out of the bay and set it aside in a safe, static-free location.

5. Place either another switch or a filler module in the bay.

Important: Complete this step within 1 minute. For more information, see

“Installing the CN4093” on page 20 .

6. If you placed the switch in the bay, reconnect the ports that you disconnected in

Step 2

and attach any additional cables that are required by the switch.

For additional information about connecting ports, see

“Connecting Switch

Ports” on page 23

, and also the documentation that comes with the port transceiver modules, DACs, cables, and the optional network devices to which the cables have been connected.

Connecting Switch Ports

The switch includes a variety of external port options. Fixed ports, such as the

RJ-45 management port, can be connected directly by attaching the appropriate cable. Modular ports, such as Small Form-factor Pluggable Plus (SFP+) and Quad

Small Form-factor Pluggable Plus (QSFP+) ports, require the installation of a transceiver module before the cable can be attached. This section covers each supported port type separately:



“The Serial Console Port” on page 23



“The RJ-45 Management Port” on page 24



“SFP+ Ports” on page 26



“QSFP+ Ports” on page 29

Notes:

 The illustrations in this document might differ slightly from your hardware.

 While the information in this section describes the 10 Gigabit Ethernet (GbE)

SFP+ transceiver module, it also applies to the 1 GbE SFP transceiver module.

 The switch supports MSA-compliant copper DACs, up to 5 m (16.5 ft.) in length.

The Serial Console Port

Connecting the Serial Console Cable

To use the serial console, connect a serial cable to the RS-232 serial console port of the switch and the other end of the cable to the console device.

Note: You must use one of the two cables in the Serial Access Cable option.

If your console device uses a standard RS-232 DB9 connector, attach the included mini-USB-to-DB9 serial cable. Otherwise, if your console device uses an RJ-45 connector, attach the included mini-USB-to-RJ-45 serial cable and a user-supplied

RJ-45 adapter cable. Your adapter cable depends on the pin out required by your console device. Pin out of the mini-USB-to-RJ-45 cable is as follows:

Information LEDs

The front panel of the switch has LEDs for system and port status. The Power,

Locator, and Error LEDs indicate the switch status. The Link (LINK) and Activity

(TX/RX) LEDs indicate the status of the external ports.

Notes:



A yellow LED on the Lenovo Flex System chassis is lit when a system error or event has occurred. To identify the error or event, check the Lenovo Flex System management-module event log or the switch system log.



During POST, the switch Power LED continuously flashes. Additionally, all of the switch status LEDs and the licensed Port LEDs are lit as a visual indication they are working. Once POST has successfully completed, the switch Power

LED remains on and the switch Error LED is off.

Any errors that are detected during POST are written to the system log. For information about the command to read the system log, see the Command Reference for the switch.

When POST errors are written to the system log, these errors are also written to the

Lenovo Flex System management-module event log. If a hardware error, such as a current fault occurs, the CMM displays it. If a firmware error occurs, the CMM displays the

Module did not complete POST message and a post error code that indicates the test that was running when the error was detected.

Note: You can also use the CMM to make sure that the switch is operating correctly. For more information, see the CMM documentation.

Chapter 3. Configuring the CN4093

The switch has an internal Ethernet path to the Chassis Management Module

(CMM), the external Ethernet data ports, an external management port, and a serial console port. The switch supports two remote-access modes for management through Ethernet connections. You can select the mode that is best suited for your

Lenovo Flex System environment.

 Default mode: The default mode uses the internal path to the CMM only. In this mode, the remote-access link to the management console must be attached to the

Ethernet connector on the CMM. The Internet Protocol (IP) addresses and

Simple Network Management Protocol (SNMP) parameters of the switch can be automatically assigned by the Lenovo Director Flex System Deployment wizard

(when available), or you must assign them through the Lenovo Flex System

Management and Configuration program. This mode enables you to provide a secure LAN for management of the Lenovo Flex Systems subsystems that is separate from the data network. See

“Establishing an Interface Through the

CMM” on page 39

for more information.

 External management mode: External management mode allows for the use of alternate management entities to control and configure the switch. You must enable external management in order to manage the switch using the dedicated external management port (EXTM) or any of the external data ports

(EXT1-EXT22, in-band switch management). This mode can be used instead of or in addition to access through the CMM. This mode can be enabled only through the CMM configuration interface. When this mode is enabled, the external ports support both management and data traffic.

This mode enables the use of additional switch IP addresses on different IP subnets than the CMMs. This is useful when the switches are to be managed and controlled as part of the overall network infrastructure, while secure management of other Lenovo Flex System subsystems is maintained through

the CMM. See “Enabling Management Through Data Ports” on page 40 for

additional instructions about configuring the switch for this mode of operation.

The RS-232 console port provides an alternative path to manage and configure the switch for local access.

Important:

 Before you configure the switch, make sure that the CMM is correctly configured. For more information about configuring the CMM, see the following documents:

– Lenovo Flex System Chassis Management Module Installation Guide

– Lenovo Flex System Chassis Management Module User’s Guide

 The initial default IP address assigned to the switch by the CMM is

192.168.70.120, 192.168.70.121, 192.168.70.122, or 192.168.70.123 depending on the bay where the switch is installed.

 If you change the IP address of the switch and restart the Lenovo Flex System chassis, the switch maintains this new IP address as its default value.

 The CMM and the switch can communicate with each other only if they are on the same IP subnet.


37

 When configuring the switch, you must execute the copy running-config startup-config command if you want the configuration change to persist beyond the next reboot of the switch. This command stores the current switch configuration and all changes in nonvolatile memory.

If the switch restarts and the CMM cannot apply the saved configuration, the switch defaults to the configuration that was previously saved. If the IP subnet address of the switch does not match the IP subnet address of the CMM, you can no longer manage the switch from the CMM. For more information about configuring the switch, see the Command Reference for your specific switch and its installed firmware.

 When you use the management-module Web interface to update the switch configuration, the management-module firmware saves the new configuration in internal nonvolatile memory. If the switch restarts, the CMM applies the saved configuration to the switch. For more information, see the Application

Guide and the Command Reference for your specific switch and its installed firmware.

 For switch communication with a remote management station, such as an

Lenovo Director management server, through the management-module external

Ethernet port, the switch internal-network interface and the management-module external interface must be on the same IP subnet.

For specific details about configuring the switch and preparing for system installation, see the documentation listed in

“Related Documentation” on page 13

.

Notes:

 Unless otherwise stated, references to the CMM apply only to the Lenovo Flex

System Chassis Management Module, which is the only type of management module that supports the switch.

 Throughout this document, the management-module Web-based user interface is also known as the Lenovo Flex System management-module Web interface.

 Throughout this document, the user name is also known as the login name or user ID for logging on to interfaces or programs.

 The screens that are described or referenced in this document might differ slightly from the screens that are displayed by your system. Screen content varies according to the type of Lenovo Flex System chassis and the firmware versions and options that are installed.

38


Establishing an Interface Through the CMM

For remote management functions, the switch requires a TCP/IP interface. This can be configured through the CMM as follows:

1. Log on to the CMM Command-Line Interface (CLI) as described in the CMM documentation. If necessary, obtain the IP address of the CMM from your system administrator.

Note: The default User ID for the CMM is USERID, and the default password is

PASSW0RD (where the sixth character is the number zero, not the letter

O). The User ID and password fields are case-sensitive.

2. Set the environment to the bay where you installed the switch: system> env -T system:switch[1]

3. Execute the ifconfig command to configure the IP parameters you wish to use for remote switch management. For example,

ifconfig -i 192.168.70.1 -s 255.255.255.0 -g 192.168.70.100

where the

-i parameter is the IPv4 address, -s is the subnet mask, and -g is the default gateway.

4. You should now be able to ping the switch from the CMM using this address: system:switch[1]> ping -i 192.168.70.1

Reply from 192.168.70.1: bytes=64 time=0.198ms




One the switch management address is configured, you can use it to establish a

Secure Shell (SSH)/Telnet session or Web session (HTTPS/HTTP) .

Note: SSH and HTTPs are enabled by default. Telnet and HTTP can be enabled once you have initially logged into the switch.

The Web interface application and the SSHv2/Telnet client software provide different ways to access the same internal-switching firmware and configure it.

If your system application requires that you use the Web interface application, see

“Accessing the Switch Through the Browser-Based Interface” on page 43

for additional information.

If your system application requires that you use the SSHv2/Telnet client software, see

“Accessing the Switch Through the SSHv2/Telnet Interface” on page 41 for

additional information.

The switch can be manage through the CMM, a compute node, or a management station that is connected through the swtich. Data traffic is allowed on internal and external switch ports.

To enable management through data ports, complete the following steps:

1. Log on to the CMM CLI as described in the CMM documentation. If necessary, obtain the IP address of the CMM from your system administrator.

2. Set the environment to the bay where you installed the switch: system> env -T system:switch[1]

3. Execute the ifconfig command to enable data ports and external management:

ifconfig -ep enabled -em enabled

4. You should now be able to manage the switch using its data ports or external management port.

Note: “External management” refers to means other than by the CMM. To externally manage the switch, additional IP interfaces must be configured. For more information see the Application Guide for your specific switch and its installed firmware.

40


Accessing the Switch Through the SSHv2/Telnet Interface

The switch supports a Command-Line Interface (CLI) that you can use to configure and control the switch over the network through the SSHv2/Telnet client software.

You can use the CLI to perform many basic network-management functions. In addition, you can configure the switch for management through an SNMP-based network-management system.

If you know the IP address for the switch ( “Establishing an Interface Through the

CMM” on page 39

) and you have an existing network connection, you can use the

SSHv2/Telnet client software from an external management station to access and control the switch. Optimally, the management station and the switch should be on the same subnet. Otherwise, you must use a router and configure a gateway address on the switch. If you have to obtain the IP address for the switch or establish a network connection, contact your system or network administrator.

The switch also supports user-based security that enables you to prevent unauthorized users from accessing the switch or changing its settings.

To connect to the switch through the SSHv2/Telnet interface, refer to your client software for specific instructions on how to invoke a session. For example, using the Microsoft Telnet Client, you would complete the following steps:

1. From a DOS command-line prompt, type telnet <switch IP address> and press

Enter.

2. When prompted, enter your user name and password.



When logging in to a switch for the first time, the default switch administrator user name is

USERID, and the default password is PASSW0RD (where the sixth character is the number zero, not the letter O). The User ID and password fields are case-sensitive. For security purposes, you will be prompted to change the administrator password after the first successful login.



Otherwise, if you have an assigned user account, use your assigned user name and password.

Important: Any configuration changes made using the management interfaces will be lost during the next switch reboot unless you execute the copy running-config startup-config command. This command stores the current switch configuration and all changes in nonvolatile memory.

For more information about configuring through the CLI, see the Application Guide and Command Reference for your specific switch and its installed firmware.


41

Accessing the Switch Through the Serial-Port Interface

The serial port provides basic communication RS-232 serial-data transfer through a terminal emulation program (such as Hyperterminal). Because messages from the power-on self-test (POST) and all initialization information are transmitted through the serial port, you can use the serial port to log in to the switch and access and configure the internal switching firmware.

To log in to the switch, complete the following steps:

1. Connect one end of the specifically designed serial cable that comes with your device into the RS-232 port and connect the other end to the management station.

For additional information, see

“Connecting the Serial Console Cable” on page 23

.

2. On the management station, open a console window and make sure that the serial port is configured with the following settings:



9600 baud



8 data bits



No parity



1 stop bit



No flow control

3. When prompted, enter your user name and password.








The serial port is compatible with the standard 16550 Universal Asynchronous

Receiver/Transmitter (UART) protocol. The RS-232 serial port is enabled by default.

42


Accessing the Switch Through the Browser-Based Interface

Before you can access and start the browser-based interface, make sure that you have completed the following procedures:

 Configure at least one IP interface on the switch. Refer to

“Establishing an

Interface Through the CMM” on page 39

for more information.

 Enable frames and the JavaScript program in your Web browser.

The following hardware and software are required for the Web interface:

 A frame-capable Web-browser program, such as Internet Explorer (version 7.0 or later), Mozilla Firefox (version 8.0 or later), or Google Chrome (version 16.0 or later)

 A computer or workstation with network access to the switch

To start the browser-based interface, complete the following steps:

1. Start a Web browser. The Web-browser window opens.

2. In the URL field, enter the IP address of the switch, in the following format:

https://xxx.xxx.xxx.xxx.

The login window opens.

3. When prompted, enter your user name and password and click OK.



43

Initial Configuration

The operating firmware on the switch contains default configuration files that are installed during the firmware installation. These initial configuration settings are not in a separate configuration file but are components of the firmware. When you restore the switch to factory defaults, the original configuration is restored.

After you log on to the switch, you must perform basic configuration tasks. For more information about configuring and managing the switch, see the Application

Guide and Command Reference for your specific switch and its installed firmware.

44


Chapter 4. Updating the Firmware and Licensing

This chapter describes how to determine the level of the firmware that is installed on the switch, how to obtain the latest level of switch firmware, how to upgrade the firmware, how to acquire additional feature licenses, and how to reset the switch to activate the firmware upgrade.

Note: Configuration settings may be lost during some firmware updates. Before updating the firmware, save a copy of the configuration on a separate device. In the event of a failed update, the saved configuration can be restored. For more information about the configuration file, see the Application Guide and Command

Reference for your specific switch and installed firmware.


45

Determining the Level of Switch Firmware

After you install the switch in the Lenovo Flex System chassis, make sure that the latest firmware is installed on the switch. To determine the level of the firmware that is installed, complete the following steps.

Obtaining the Latest Level of Switch Firmware

If firmware updates are available, you can download them from the Lenovo website: http://support.lenovo.com/

Note: Changes are made periodically to the Lenovo website. Procedures for locating firmware and documentation might vary slightly from what is described in this document.

Attention:

 Before updating the firmware, save a copy of the configuration to a separate device. In the event of a failed update, the saved configuration can be restored.

For more information about the configuration file, see the Application Guide and

Command Reference for your specific switch and firmware version.

 Installing the incorrect firmware might cause the switch to malfunction. Before you install firmware, read any release notes, readme files and change history files that are provided with the downloaded update. These files contain important information about the update and the procedure for installing the update, including any special procedure or requirements for updating from an early firmware version to the latest version.

47

Upgrading the Switch Firmware

You can upgrade the switch firmware by using an FTP, TFTP or SFTP file server.

Typically, the file server runs as an application under your operating system. Make sure that the file server application is installed on your file server; then, download the switch firmware images from the Lenovo website into a directory on your file server. Then enable the file server and set its default directory to the directory where the switch firmware image resides.

Note: Updating the firmware involves rebooting the switch. If you have made any configuration changes you wish to persist beyond the upgrade process, you must type the copy running-config startup-config command. This command stores the current switch configuration and all changes to nonvolatile memory.

To transfer the switch firmware image files from the FTP, TFTP or SFTP file server to the switch, you can establish a Secure Shell (SSH) v2 or Telnet session through the CMM. Ping the file server to make sure that you have a connection. The session performs optimally if all three network entities (file server, CMM, and switch IP addresses) are on the same subnet. Otherwise, you must use a router and configure a gateway address on the switch. Use the management-module interface to configure the IP addresses of the CMM external interface (eth0) and the switch so that they are both on the same subnet as the file server.

Examples of IP addresses and masks are described in the following table.

Network entity

FTP, TFTP or SFTP file server

Mask

255.255.255.0

255.255.255.0

255.255.255.0

Note: With this configuration, you can ping the switch from the file server.

Switch Firmware Upgrade Example

To upgrade the switch firmware, complete the following steps.

1. Log in to the switch (see

“Configuring the CN4093” on page 37

for more information).

2. At the switch Command-Line Interface (CLI) prompt, execute the following commands to upload the firmware image to the switch.

CN 4093> enable

CN 4093# copy {ftp|tftp|sftp} {image1|image2} addr <server address> file

<image file>

{data-port|extm-port|mgt-port}

Where server address is the IP address of file server, and image file is the file name of the firmware image as it appears in the file server operating-system.

3. Execute the following command to upload the boot image to the switch.

CN 4093# copy {ftp|tftp|sftp} boot addr <server address> file <boot file>

{data-port|extm-port|mgt-port}

Where boot file is the file name of the boot image as it appears in the file server operating-system.

4. Reset and restart the switch as described in

“Resetting and Restarting the Switch” on page 50

.


49

Resetting and Restarting the Switch

To activate the new image or images, you must reset the switch. To reset the switch, complete the following steps:

1. Log on to the CMM CLI as described in the CMM documentation. If necessary, obtain the IP address of the CMM from your system administrator.

2. Set the environment to the bay where you installed the switch. For example: system> env -T system:switch[1]

3. Execute the reset command to restart the switch: system:switch[1]> reset

4. Wait for the POST to complete. This may take up to 2 minutes.

5. Execute the info command for the switch that was just restarted and note the corresponding level of the firmware for the switch. Confirm that the firmware build number reflects the correct firmware release. For example: system:switch[1]> info

Acquiring Feature Licenses

The base license provides support for a single compute node of fourteen internal 10

Gigabit Ethernet (GbE)/Fibre Channel over Ethernet (FCoE) ports, two external 10

GbE/FCoE Small Form Pluggable Plus (SFP+) ports, and six Omni Ports which can be used either for 10 GbE/FCoE or 4/8 Gigabits per second (Gbps) Fibre Channel

(FC) connections. Additional ports are available with optional licenses. There are two upgrades that are available for the CN4093.

Upgrade 1 adds supports for the following:


 Two external 40 GbE/FCoE Quad Small Form Pluggable Plus (QSFP+) ports, which can be used as eight 10GbE/FCoE SFP+ ports

Upgrade 2 adds support for the following:


 Six additional Omni Ports allowing the same port to be used either as a 10

GbE/FCoE SFP+ port or as a 4 Gbps or 8 Gbps FC port

Note: Upgrade 1 and Upgrade 2 are independent and can be installed in any order, with or without the other.

Upgrade licenses are unique to each switch and are non transferable.

To acquire an upgrade license activation key, purchase the Authorization Code and locate the unique ID (UID) on the switch serial number (SN) label (bottom or rear of switch module). The UID is the last twelve characters of the switch serial number. This serial number is located on the part number (PN) label (bottom or rear of switch module) and is also displayed during a login to any of the user interfaces. For example, SN (UID): Y250CM294998. For more information about

locating the switch identification labels, see “Before Installing the CN4093” on page 17

.

In the event of the switch replacement, new activation key files based on the serial number of the replacement unit must be acquired and installed. If the replacement is handled through Lenovo Service and Support, your original Authorization Code is transferred to the serial number of the replacement unit.

You can use the Lenovo website to perform the following tasks:

 Request a new activation key

 Check an authorization code to see what feature it enables and how many remaining times it can be used to create a key

 Retrieve the history of feature activation on a selected device

 Retrieve the history of feature activation on a selected authorization code

 Retrieve a lost authorization code

 Manage your Lenovo customer number

 Find help for the Features on Demand feature activation process

 Provide feedback to Lenovo about the Features on Demand process


51

Note: Your Lenovo ID and password are required to log into the Features on

Demand website.

52


Installing Feature Licenses

Once Features on Demand activation key files have been acquired, they must be installed on the switch. The example below illustrates use of the switch CLI, but other interfaces may also be used, such as the Browser Based Interface (BBI), or

Simple Network Management Protocol (SNMP). For more information, see the

Application Guide and Command Reference for your specific switch and its installed firmware.

When installing licenses, please note the following requirements:

 A switch reboot is required to fully activate the license(s). If you have made any configuration changes you wish to persist beyond the reboot, you must execute the copy running-config startup-config command. This command stores the current switch configuration and all changes to nonvolatile memory.

 Both license key files can be installed prior to the switch reset in order to activate both at the same time.

Complete the following steps to install feature licenses:

1. Log in to the switch (see

“Configuring the CN4093” on page 37

for more information).

2. At the switch CLI prompt, type the following command.

CN 4093> enable

CN 4093# software-key

CN 4093(Software-Key)# enakey addr <server address> keyfile <file name> protocol

{tftp|sftp} {data-port|extm-port|mgt-port}

where server address is the IP address of the TFTP or SFTP file server, and file

name is the name of the licence key file as it appears in the file server operating system.

3. Once the key file transfer is complete, reset the switch to activate the license(s) (see

“Resetting and Restarting the Switch” on page 50

).

Chapter 5. Solving Problems

This section provides basic troubleshooting information to help you solve some problems that might occur while you are setting up the switch. The Application

Guide for the switch provides more details about troubleshooting the switch.

If you cannot locate and correct a problem by using the information in this section, see

“Getting Help and Technical Assistance” on page 59 .


55

Running POST

To ensure that it is fully operational, the switch processes a series of tests during power-up or a restart (Power-On Self-Test, or POST). These tests may take up to two minutes to complete. The Lenovo Flex System Chassis Management Module

(CMM) reads the test results and displays them for you. During normal operation, these tests are completed without error, and the green switch Power LED is lit.

However, if the switch fails POST, the yellow Error LED on the switch and the system-error LED on the chassis are lit. An event is stored in the event log in the system status panel of the CMM. The specific failure is displayed on the system status I/O module panel of the CMM.

Note: For the locations and descriptions of the switch LEDs, see

“Locating the

Information Panels, LEDs, and External Ports” on page 32

.

56


POST Errors

There are two types of errors: noncritical and critical. A noncritical error applies to one port, and the switch is operational. You can continue to operate the switch; however, you must replace it as soon as possible. When critical errors occur, the switch does not operate.

To view POST results, complete the following steps:

1. Log on to the CMM Command-Line Interface (CLI) as described in the CMM documentation. If necessary, obtain the Internet Protocol (IP) address of the CMM from your system administrator. The login window opens.

2. Turn off the power to the switch; then, turn it on again.

3. After POST is completed, the CMM displays the results. Refresh the window to view the POST results. If a critical error occurs, replace the switch. If a noncritical error occurs, see the switch error log for additional details.

The following table describes the basic critical and noncritical failures. This abbreviated list is representative; it is not an exhaustive list. An error code is associated with each failure. Error codes are displayed on the CMM Switch

Information window. Be sure to note the applicable error code and corresponding failure. You might have to provide this information when you call for service. For

details, see “Getting Help and Technical Assistance” on page 59 .

Important Notes

Processor speed indicates the internal clock speed of the microprocessor; other factors also affect application performance.

CD or DVD drive speed is the variable read rate. Actual speeds vary and are often less than the possible maximum.

When referring to processor storage, real and virtual storage, or channel volume,

KB stands for 1 024 bytes, MB stands for 1 048 576 bytes, and GB stands for 1 073

741 824 bytes.

When referring to hard disk drive capacity or communications volume, MB stands for 1 000 000 bytes, and GB stands for 1 000 000 000 bytes. Total user-accessible capacity can vary depending on operating environments.

Maximum internal hard disk drive capacities assume the replacement of any standard hard disk drives and population of all hard-disk-drive bays with the largest currently supported drives that are available from Lenovo.

Maximum memory might require replacement of the standard memory with an optional memory module.

Each solid-state memory cell has an intrinsic, finite number of write cycles that the cell can incur. Therefore, a solid-state device has a maximum number of write cycles that it can be subjected to, expressed as total bytes written (TBW). A device that has exceeded this limit might fail to respond to system-generated commands or might be incapable of being written to. Lenovo is not responsible for replacement of a device that has exceeded its maximum guaranteed number of program/erase cycles, as documented in the Official Published Specifications for the device.
