The PA-T3 serial port adapter can be installed in the following slots on the hardware platforms
described in this document:
•
•
•
VIP2—Port adapter slot 0 and port adapter slot 1
•
Cisco 7200 series routers—Port adapter slot 1 and slot 2 of the Cisco 7202; port adapter slot 1
through slot 4 of the Cisco 7204 and Cisco 7204VXR; port adapter slot 1 through slot 6 of the
Cisco 7206 and Cisco 7206VXR
•
Cisco uBR7200 series routers—Port adapter slot 1 and slot 2 of the Cisco uBR7246; port adapter

Catalyst RSM/VIP2—Port adapter slot 0 and port adapter slot 1
Cisco 7100 series routers—Port adapter slot 3 in the Cisco 7120 series and port adapter slot 4 in
the Cisco 7140 series
The one-port PA-T3 serial port adapter provides two network interfaces per VIP2 for Cisco 7000
series and Cisco 7500 series routers, two network interfaces per Catalyst RSM/VIP2, and one
high-speed interface on the Cisco 7200 series and Cisco uBR7200 series routers. The two-port
PA-2T3 serial port adapter provides four network interfaces per VIP2 for Cisco 7000 series and
Cisco 7500 series routers, four network interfaces for the Catalyst RSM/VIP2, and two high-speed
interfaces on the Cisco 7200 series and Cisco uBR7200 series routers. Serial network interfaces
reside on modular port adapters, which provide a direct connection between the high-speed bus in
the router and the external networks. The PA-T3 serial port adapter provides a full-duplex
synchronous serial PA-T3 interface for transmitting and receiving data at rates of up to 34 megabits
per second (Mbps).
The port adapter supports both 16- and 32-bit cyclic redundancy checks (CRCs). The default is
16-bit CRCs; to enable 32-bit CRCs, you use a configuration command. For a description of the CRC
function, see the “Configuring Cyclic Redundancy Checks” section on page 8-13.
The VIP2 and Catalyst RSM/VIP2 support online insertion and removal (OIR), but individual port
adapters with a VIP2 or Catalyst RSM/VIP2 do not support OIR. To replace port adapters in the
Cisco 7000 series and Cisco 7500 series routers, and the Catalyst 5000 series switches, you must first
remove the VIP2 or Catalyst RSM/VIP2 from the chassis and then replace port adapters as required.
OIR is supported for port adapters in the Cisco 7200 series and Cisco uBR7200 series routers.

Caution The VIP2 requires that the host Cisco 7000 series router have the RSP7000 and RSP7000CI
installed. The VIP2 does not operate properly with the Route Processor (RP), Switch Processor (SP), or
Silicon Switch Processor (SSP) installed in the host Cisco series router.
The PA-T3 serial port adapter is considered a high-bandwidth port adapter; therefore, and at a
minimum, Cisco recommends that the PA-T3 serial port adapter be installed on the VIP2-15 or
Catalyst RSM/VIP2 motherboard (with 1 MB of SRAM and 8 MB of DRAM). Installation of the
PA-T3 serial port adapter on the VIP2-10 (with 512 KB of SRAM and 8 MB of DRAM) is not
recommended.

PA-T3 Serial Port Adapter Installation and Configuration
PA-T3 Port Adapter LEDs
Note The VIP2 and Catalyst RSM/VIP2 supports online insertion and removal (OIR), but
individual port adapters do not. To replace port adapters in the Cisco 7000 series and Cisco 7500
series routers, and the Catalyst 5000 series switches, you must first remove the VIP2 or
Catalyst RSM/VIP2 from the chassis and then replace port adapters as required. OIR is supported
for port adapters in the Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers. Port
adapters have a handle attached, but this handle is occasionally not shown in illustrations in this
publication to allow a full view of detail on the port adapter’s faceplate.
In the Cisco 7000 series, Cisco 7100 series, Cisco 7500 series, and Cisco uBR7200 series routers,
and the Catalyst 5000 series switches, there are no restrictions on slot locations or sequence;
however, in the Cisco 7200 series routers, there are specific configuration guidelines that must be
observed for high-bandwidth port adapters.
For specific Cisco 7200 series routers hardware configuration information and for memory
configuration guidelines, refer to the document Cisco 7200 Series Port Adapter Hardware
Configuration Guidelines, which shipped with your Cisco 7200 series chassis and is also available
on the Cisco Connection Documentation, Enterprise Series CD-ROM.
To determine if your Cisco 7000 series, Cisco 7100 series, Cisco 7500 series, Cisco 7200 series, or
Cisco uBR7200 series router, or Catalyst RSM/VIP2, is compatible with the PA-T3 serial port
adapter, use the show version command to display the current hardware configuration of the router,
including the system software version that is currently loaded and running. You can check the
version of the default ROM image by removing the board and checking the ROM labels, or by
configuring the interface or system software to boot from ROM, restarting the system, and using the
show version command to check the running version.
Use the show version command to display the current system software version. In the following
example, the running system software is Release 11.1(16)CA.

PA-T3 Receptacles and Cables
The PA-T3 port adapter serial interface cable, which is a 75-ohm coaxial cable, connects your router
to a T3 serial network. Serial cables conform to EIA/TIA-612 and EIA/TIA-613 specifications. The
serial ports on the PA-T3 serial port adapter are considered to be data terminal equipment (DTE)
devices.
On a single PA-T3 serial port adapter, there are one or two T3 serial ports, each with two connectors
(receive and transmit), where you connect the Cisco 75-ohm coaxial cable. The 75-ohm coaxial
cable (Cisco part number CAB-ATM-DS3/E3) for the PA-T3 serial port adapter is available only

Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
•
Before beginning any procedures 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 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.
Do not work alone when potentially hazardous conditions exist and never assume that power has
been disconnected from a circuit; always check.
Telephone Wiring Guidelines
Use the following guidelines when working with any equipment that is connected to telephone
wiring or to other network cabling:
•
•
Never install telephone wiring during a lightning storm.
•
Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
•
Use caution when installing or modifying telephone lines.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet
locations.
Preparing for Installation 2-7
FCC Class A Compliance
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Port adapters and processor modules
consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI)
shielding and connectors are integral components of the carrier. Although the metal carrier helps to
protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
•
•
•
Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
•
When removing a component, use any available ejector levers or captive installation screws to
release the bus connectors from the backplane or midplane.
•
Handle carriers by available handles or edges only; avoid touching the printed circuit boards or
connectors.
•
Place a removed board component-side-up on an antistatic surface or in a static shielding
container. If you plan to return the component to the factory, immediately place it in a static
shielding container.
•
Avoid contact between the printed circuit boards and clothing. The wrist strap only protects
components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
•
Never attempt to remove the printed circuit board from the metal carrier.
Connect the equipment end of the strap to an unfinished chassis surface.
When installing a component, use any available ejector levers or captive installation screws to
properly seat the bus connectors in the backplane or midplane. These devices prevent accidental
removal, provide proper grounding for the system, and help to ensure that bus connectors are
properly seated.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should
be between 1 and 10 megohms (Mohm).
FCC Class A Compliance
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which
case users will be required to correct the interference at their own expense.
You can determine whether your equipment is causing interference by turning it off. If the
interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices.
If the equipment causes interference to radio or television reception, try to correct the interference
by using one or more of the following measures:
•
•
•
2-8
Turn the television or radio antenna until the interference stops.
Move the equipment to one side or the other of the television or radio.
Move the equipment farther away from the television or radio.

Depending on the circumstances, you might need to install a new port adapter on a VIP2
motherboard or replace a failed port adapter in the field. In either case, you need a number 1 Phillips
screwdriver, an antistatic mat on which you can place the removed interface processor, and an
antistatic container in which you can place a failed port adapter for shipment back to the factory.
Note The PA-T3 serial port adapter can be installed on a VIP2-15, VIP2-20, or VIP2-40
motherboard; however, installation on the VIP2-10 is not recommended.
Caution To prevent system problems, do not remove port adapters from the VIP2 motherboard or
attempt to install other port adapters on the VIP2 motherboard while the system is operating. To
install or replace port adapters, first remove the VIP2 from its interface processor slot.
Note Each port adapter circuit board is mounted to a metal carrier and is sensitive to ESD damage.
The following procedures should be performed by a Cisco-certified service provider only. The VIP2
supports online insertion and removal (OIR), but individual port adapters do not. To replace port
adapters, you must first remove the VIP2 from the chassis and then install or replace port adapters
as required. If a blank port adapter is installed on the VIP2 in which you want to install a new port
adapter, you must first remove the VIP2 from the chassis and then remove the blank port adapter.
VIP2 and the PA-T3 Port Adapter 3-3
Removing a Port Adapter
When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot. This
allows the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions
requirements, and encourages air to flow through the chassis properly. If you plan to install a new
port adapter, you must first remove the blank port adapter.
Removing a Port Adapter
Following is the standard procedure for removing any type of port adapter on the VIP2:
Step 1
Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.
Note If you want to install a new port adapter on a VIP2 with a single port adapter, you
must first remove the blank port adapter from the port adapter slot in which you want to
install the new port adapter.
Step 2
For a new port adapter installation or a port adapter replacement, disconnect any interface
cables from the ports on the front of the port adapter, although this is not required. You
can remove VIP2s with cables attached; however, we do not recommend it.
Step 3
To remove the VIP2 from the chassis, follow the steps in the section “Removing a VIP2”
in the configuration note Second-Generation Versatile Interface Processor (VIP2)
Installation and Configuration, which shipped with your VIP2. Place the removed VIP2
on an antistatic mat.
Step 4
Locate the screw at the rear of the port adapter (or blank port adapter) to be replaced.
(See Figure 3-3.) This screw secures the port adapter (or blank port adapter) to its slot.

Step 5
Remove the screw that secures the port adapter (or blank port adapter).
Step 6
With the screw removed, grasp the handle on the front of the port adapter (or blank port
adapter) and carefully pull it out of its slot, away from the edge connector at the rear of
the slot. (See Figure 3-4.)

Depending on your circumstances, you might need to install a new port adapter in a Cisco 7200
series router or replace a failed port adapter in the field. In either case, no tools are necessary; all port
adapters available for the Cisco 7200 series connect directly to the router midplane and are locked
into position by a port adapter lever. When removing and replacing a port adapter, you need an
antistatic mat onto which you can place a removed port adapter and an antistatic container into which
you can place a failed port adapter for shipment back to the factory.
Cisco 7200 Series and the PA-T3 Port Adapter 5-1
Removing a Port Adapter
Note The Cisco 7200 series routers support online insertion and removal; therefore, you do not
have to power down the Cisco 7200 series routers when removing and replacing a port adapter.
When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router
to conform to EMI emissions requirements and to allow proper airflow across the port adapters. If
you plan to install a new port adapter in a slot that is not in use, you must first remove a blank port
adapter.
Removing a Port Adapter
Following is the procedure for removing a port adapter from a Cisco 7200 series router:
Step 1
Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.
Step 2
Place the port adapter lever for the desired port adapter slot in the unlocked position. The
port adapter lever remains in the unlocked position. (See Figure 5-2.)

Configuring the PA-T3 Interfaces
To continue your PA-T3 port adapter installation, you must configure the PA-T3 interfaces. The
instructions that follow apply to all supported platforms. Minor differences between the platforms
are noted. This chapter contains the following sections:
•
•
•
•
•
•
•
•
Using the EXEC Command Interpreter, page 8-2
Identifying Port Adapter Slot and T3 Interface Port Numbers, page 8-2
Shutting Down an Interface, page 8-7

Configuration Example, page 8-11
Customizing the PA-T3 Serial Port Adapter, page 8-12
Configuring Cyclic Redundancy Checks, page 8-13
Checking the Configuration, page 8-14
If you installed a new PA-T3 port adapter or if you want to change the configuration of an existing
interface, you must enter configuration mode using the configure command. If you replaced a PA-T3
port adapter that was previously configured, the system recognizes the new PA-T3 port adapter
interfaces and brings each of them up in their existing configuration.
After you verify that the new PA-T3 port adapter is installed correctly (the enabled LED goes on),
use the privileged-level configure command to configure the new interfaces. Be prepared with the
information you need, such as the following:
•
•
•
•
Protocols you plan to route on each new interface
IP addresses if you will configure the interfaces for IP routing
Use of bridging on the new interfaces
Timing source for each new interface and clock speeds for external timing
For a summary of the configuration options available and instructions for configuring interfaces on
the PA-T3 port adapter, refer to the appropriate configuration publications listed in the “Related
Documentation” section on page vi.
Configuration commands are executed from the privileged level of the EXEC command interpreter,
which usually requires password access. Contact your system administrator, if necessary, to obtain
access. (See the “Using the EXEC Command Interpreter” section on page 8-2 for an explanation of
the privileged level of the EXEC.)
Configuring the PA-T3 Interfaces 8-1
Using the EXEC Command Interpreter
Using the EXEC Command Interpreter
You modify the configuration of your router through the software command interpreter called the
EXEC (also called enable mode). You must enter the privileged level of the EXEC command
interpreter with the enable command before you can use the configure command to configure a new
interface or change the existing configuration of an interface. The system prompts you for a
password if one is set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket
(>). At the console terminal, use the following procedure to enter the privileged level:
Step 1
At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for
a privileged-level password as follows:
Router> enable
Password:
Step 2
Enter the password (the password is case-sensitive). For security purposes, the password
is not displayed.
When you enter the correct password, the system displays the privileged-level system
prompt (#):
Router#
Proceed to the following sections to configure the new interfaces.
Identifying Port Adapter Slot and T3 Interface Port Numbers
This section describes how to identify port adapter slot and PA-T3 interface port numbers for the
Cisco 7200 series routers, the Cisco uBR7200 series routers, the VIP2, and the Catalyst RSM/VIP2.
Cisco 7200 Series and Cisco uBR7200 Series Ports
Physical port addresses specify the actual physical location of each interface port on a Cisco 7200
series router (see Figure 8-1) or a Cisco uBR7200 series router (see Figure 8-2). This address is
composed of a two-part number in the format port adapter slot number/interface port number, as
follows:
•
•
The first number identifies the chassis slot in which the PA-T3 serial port adapter is installed.
The second number identifies the interface port on each PA-T3 serial port adapter; the interface
port is always numbered as interface 0 for the one-port PA-T3 serial port adapter and 0 or 1 for
a two-port PA-2T3 serial port adapter.
Interface ports maintain the same address regardless of whether other port adapters are installed or
removed from the slot. However, when you move a port adapter to a different slot, the first number
in the address changes to reflect the new chassis slot number.
In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right,
beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202,
slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR.
Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present.
Figure 8-1 shows the port adapter slots and interface ports of a Cisco 7206. The individual interface
port numbers always begin with 0. The number of additional ports depends on the number of ports
on a port adapter.
8-2
PA-T3 Serial Port Adapter Installation and Configuration
Cisco 7200 Series and Cisco uBR7200 Series Ports
Note The I/O controller is available with or without a Fast Ethernet port. You can install both I/O
controller types in all Cisco 7200 series routers; however, when you install an I/O controller with a
Fast Ethernet port in a Cisco 7202, the system software automatically disables the port.
For example, the serial port on a one-port PA-T3 serial port adapter in port adapter slot 3 has the
address 3/0. (See Figure 8-1.) If the PA-T3 serial port adapter is in port adapter slot 1, this same
interface port is numbered 1/0. The serial ports on a two-port PA-2T3 serial port adapter in port
adapter slot 3 has the address 3/0 and 3/1.
Note The PA-T3 serial port adapter is considered a high-bandwidth port adapter; you must observe
specific configuration guidelines. Refer to the publication Cisco 7200 Series Port Adapter Hardware
Configuration Guidelines, which shipped with your Cisco 7200 series chassis and is also available
on the Cisco Connection Documentation, Enterprise Series CD-ROM.

PA-T3 port adapter
(port number 3/0)
Figure 8-2 shows the interface ports of a PA-T3 port adapter in slot 2 of a Cisco uBR7200 series
router. The port adapter slots are numbered slot 1 and slot 2 for the Cisco uBR7246 and slot 1 for
the Cisco uBR7223 (slot 0 is always reserved for the Fast Ethernet port on the I/O controller—if
present). The individual interface port numbers always begin with 0. The number of additional ports
depends on the number of ports on a port adapter. Port adapters can occupy any port adapter slot;
there are no restrictions.
For example, the serial port on a one-port PA-T3 serial port adapter in port adapter slot 1 has the
address 1/0. (See Figure 8-2.) If the PA-T3 serial port adapter is in port adapter slot 2, this same
interface port is numbered 2/0. The serial ports on a two-port PA-2T3 serial port adapter in
port adapter slot 2 have the address 2/0 and 2/1.

Figure 8-2
You can identify interface ports by physically checking the port adapter slot number/interface port
location on the back of the router or by using software commands to display information about a
specific interface or all interfaces in the router.
VIP2 Ports
This section describes how to identify chassis slot, port adapter, and T3 interface port numbers on
the VIP2.
Note Although the processor slots in the 7-slot Cisco 7000 and Cisco 7507 and 13-slot Cisco 7513
are vertically oriented and those in the 5-slot Cisco 7010 and Cisco 7505 are horizontally oriented,
all models use the same method for slot and port numbering.
In the router, physical port addresses specify the actual physical location of each interface port on
the router interface processor end. (See Figure 8-3.) Each address is composed of a three-part
number in the format chassis slot/port adapter/interface port, as follows:
•
The first number identifies the chassis slot in which the VIP2 is installed (as shown in the sample
system in Figure 8-3).
•
•
The second number identifies the physical port adapter slot on the VIP2, and is either 0 or 1.
The third number identifies the interface port on each PA-T3 serial port adapter, which is always
numbered as interface 0 for the one-port PA-T3 serial port adapter and 0 or 1 for the two-port
PA-T3 serial port adapter.
Interface ports on the VIP2 maintain the same address regardless of whether other interface
processors are installed or removed. However, when you move a VIP2 to a different slot, the first
number in the address changes to reflect the new chassis slot number.
Figure 8-3 shows the port adapter slots and interface ports of a sample Cisco 7505 system. On the
VIP2, the first port adapter slot number is always 0. The second port adapter slot number is always 1.
The individual interface port numbers always begin with 0. The number of additional ports depends
on the number of ports on a port adapter.
8-4
PA-T3 Serial Port Adapter Installation and Configuration
Catalyst RSM/VIP2 Ports
For example, the serial port on a one-port PA-T3 serial port adapter in the first port adapter slot in
chassis slot 3, is numbered 3/0/0. (See Figure 8-3.) If the PA-T3 serial port adapter is in port adapter
slot 1, this same port is numbered 3/1/0. The serial ports on a two-port PA-T3 serial port adapter in
the first port adapter slot in chassis slot 3 are numbered 3/0/0 and 3/0/1.
Port adapters can occupy either port adapter slot; there are no restrictions.

Catalyst RSM/VIP2 Ports
This section describes how to identify the port adapter and T3 interface port numbers on the
Catalyst RSM/VIP2.
In the Catalyst RSM/VIP2, physical port addresses specify the actual physical location of each
interface port. Each address is composed of a two-part number in the format port adapter/interface
port, as follows:
•
The first number identifies the physical port adapter slot on the Catalyst RSM/VIP2, and is either
0 or 1.
•
The second number identifies the interface port on each PA-T3 serial port adapter, which is
always numbered as interface 0 for the one-port PA-T3 serial port adapter and 0 or 1 for the
two-port PA-T3 serial port adapter.
Figure 8-4 shows the port adapter slots and interface ports of a sample Catalyst 5509 switch. On the
Catalyst RSM/VIP2, the first port adapter slot number is always 0. The second port adapter slot
number is always 1. The individual interface port numbers always begin with 0. The number of
additional ports depends on the number of ports on a port adapter.
For example, the serial port on a one-port PA-T3 serial port adapter in the first port adapter slot is
numbered 0/0. (See Figure 8-4.) If the PA-T3 serial port adapter is in port adapter slot 1, this same
port is numbered 1/0. The serial ports on a two-port PA-T3 serial port adapter in the first port adapter
slot are numbered 0/0 and 0/1.
Port adapters can occupy either port adapter slot; there are no restrictions.

You can identify interface ports by physically checking the port-adapter/interface port location by
using show commands to display information about a specific interface or all interfaces in the router.
Cisco 7100 Series Ports
In the Cisco 7100 series routers, the slot number is the location in the chassis where the interface
resides and the port number is the physical port. Interfaces in the Cisco IOS software are identified
by a type, slot number, and port number. For example, serial 3/1 indicates port 1 on the serial
port adapter in slot 3.
Slots in the Cisco 7120 series routers are numbered as shown in Figure 8-5. The fixed LAN interface
is slot 0, the fixed WAN interface is slot 1, and the modular port adapter interface is slot 3. In the
Cisco 7120 series routers, slots 2 and 4 are not used. Slot 5 is the service module.

Shutting Down an Interface
Before you remove an interface that you will not replace, replace a compact serial cable, or replace
port adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies
when you reinstall the new or reconfigured interface processor. When you shut down an interface, it
is designated administratively down in the show command displays.
Follow these steps to shut down an interface:
Step 1
Enter the privileged level of the EXEC command interpreter (also called enable mode).
(See the “Using the EXEC Command Interpreter” section on page 8-2 for instructions.)
Step 2
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.
Router(config)#
Step 3
Table 8-1
End with Crtl-Z.
Specify the slot/port address of the first interface that you want shut down by entering the
subcommand interface as described in .

Enter the shutdown command as follows:
Router(config-if)# shutdown
Step 5
To shut down additional interfaces, enter the slot/port address (or slot/port
address/interface port for a VIP2) of each additional interface followed by the shutdown
command. When you have entered all the interfaces to be shut down, press Ctrl-Z (hold
down the Control key while you press Z) or enter end to exit configuration mode and
return to the EXEC command interpreter prompt.

8-8
Verify that new interfaces are now in the correct state (shutdown). To do so on the
Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series routers, use the show
interfaces serial slot/port command to display the specific interface, or use the show
interfaces command, without variables, to display the status of all interfaces in the
system.
PA-T3 Serial Port Adapter Installation and Configuration
Shutting Down an Interface
The example that follows is for Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200

Hardware is M1T-T3 pa
[display text omitted]
To verify that new interfaces are now in the correct state (shutdown) on a VIP2, use the
show interfaces serial slot/port adapter/interface command to display the specific
interface, or use the show interfaces command, without variables, to display the status of
all interfaces in the system.
The example that follows is for a VIP2:
Router# show interfaces serial 1/1/0
Serial 1/1/0 is administratively down, line protocol is down
Hardware is cyBus PODS3 Serial
[display text omitted]
To verify that new interfaces are now in the correct state (shutdown) on a
Catalyst RSM/VIP2, use the show interfaces serial port adapter/interface command to
display the specific interface, or use the show interfaces command, without variables, to
display the status of all interfaces in the system.
The example that follows is for a Catalyst RSM/VIP2:
Router# show interfaces serial 1/0
Serial 1/0 is administratively down, line protocol is down

For complete descriptions of software configuration commands, refer to the publications listed in the
“Related Documentation” section on page vi.
Performing a Basic Configuration
The following steps make up a basic interface configuration for the PA-T3 serial port adapter. Press
the Return key after each step unless otherwise noted. At any time you can exit the privileged level
and return to the user level by entering disable at the prompt:
router# disable
router>
Step 1
At the privileged-level prompt, enter configuration mode and specify that the
console terminal is the source of the configuration subcommands:
router# configure terminal
Enter configuration commands, one per line.
router(config)#
Step 2
Specify the interface to configure:
•
For a Cisco 7200 series, Cisco 7100 series, or Cisco uBR7200 series router, specify
the interface to configure by entering the subcommand interface serial followed by
the slot/port (port adapter slot number and interface port number). The example that
follows is for the interface of the port adapter in slot 3:
router(config)# interface serial 3/0
8-10
End with CNTL/Z.
PA-T3 Serial Port Adapter Installation and Configuration
Configuration Example
•
For a VIP2, specify the interface to configure by entering the subcommand interface
serial, followed by the slot/port-adapter/port (interface processor slot number, port
adapter slot number, and interface port number). The example that follows is for the
interface of the first port adapter on a VIP2 in interface processor slot 1:
router(config)# interface serial 1/0/0
•
For a Catalyst RSM/VIP2, specify the interface to configure by entering the
subcommand interface serial, followed by the port-adapter/port (port adapter slot
number and interface port number). The example that follows is for the interface of
the first port adapter on a Catalyst RSM/VIP2 in slot 0:
router(config)# interface serial 0/0
Step 3
If IP routing is enabled on the system, change to interface configuration mode and use the
ip address configuration subcommand to assign an IP address and subnet mask to the
interface, as in the following example:
router(config-if)# ip address 10.0.0.0 10.255.255.255
Step 4
In interface configuration mode, choose the internal clock source by entering the
clock source configuration subcommand, as in the following example:
router(config-if)# clock source internal
Use the no form of this command to restore the default clock source, which is line.
Step 5
In interface configuration mode, change the shutdown state to up and enable the interface
as follows:
router(config-if)# no shutdown
Step 6
Configure additional interfaces as required.
Step 7
When you have included all of the configuration subcommands to complete the
configuration, press Ctrl-Z to exit configuration mode.
Step 8
Write the new configuration to nonvolatile memory as follows:
router# copy running-config startup-config
[OK]
router#
To check the interface configuration using show commands, proceed to the section “Using show
Commands to Display Interface and System Information” section on page 8-15.
Configuration Example
The following example shows a typical configuration for the PA-T3 serial port adapter on a
Cisco 7500 series router:
router> enable
router# configure terminal
router(config)# interface serial
router(config)# interface serial 1/0/0
router(config)# ip address 10.0.0.0 10.255.255.255
router(config-if)# clock source internal
router(config-if)# no shutdown
router(config-if)# ^Z
Configuring the PA-T3 Interfaces 8-11
Customizing the PA-T3 Serial Port Adapter
Customizing the PA-T3 Serial Port Adapter
You can customize the PA-T3 serial port adapter. The features you can customize have default values
that probably suit your environment and do not require change. However, you might need to enter
configuration commands, depending on the requirements for your system configuration and the
protocols you plan to route on the interface. Perform the tasks in the following sections if you need
to customize the PA-T3 serial port adapter.
Setting the Bandwidth
In interface configuration mode, reduce effective bandwidth (range of 22 to 44210 kbps) by entering
the dsu bandwidth configuration subcommand, as in the following example:
router(config-if)# dsu bandwidth 16000
Use the no form of this command to return to the default, which is 44210.
Note The local port configuration must match the remote port configuration. For example, if you
reduce the effective bandwidth to 16000 on the local port, you must do the same on the remote port.
Defining the DSU Mode
In interface configuration mode, define the DSU interoperability mode by entering the
dsu mode [0 | 1 | 2] configuration subcommand, as in the following example:
router(config-if)# dsu mode 1
Use the no form of this command to return to the default, which is 0.
Note The local port configuration must match the remote port configuration. For example, if you
define the DSU interoperability mode as 1 on the local port, you must do the same on the remote
port. You need to know what type of DSU is at the remote port to find out if it interoperates with the
PA-T3 port adapter. For T3 serial interfaces, specify mode 0 for connection from a T3 serial port
adapter to another PA-T3 serial port adapter or a Digital Link DSU (DL3100). Specify mode 1 for
connection from a PA-T3 serial port adapter to a Kentrox DSU. Specify mode 2 for connection from
a PA-T3 serial port adapter to a Larscom DSU.
See the “Interoperability Guidelines for PA-T3 Serial Port Adapter DSUs” section on page 2-5 for
information regarding DSU feature compatibilities.
Enabling T3 Scrambling
In interface configuration mode, enable T3 scrambling by entering the scramble configuration
subcommand, as in the following example:
router(config-if)# scramble
Use the no form of this command to restore the default value, which is disabled.
8-12
PA-T3 Serial Port Adapter Installation and Configuration
Specifying T3 Framing
Note The local port configuration must match the remote port configuration. For example, if you
enable scrambling on the local port, you must do the same on the remote port.
See the “Interoperability Guidelines for PA-T3 Serial Port Adapter DSUs” section on page 2-5 for
information regarding DSU feature compatibilities.
Specifying T3 Framing
In interface configuration mode, specify T3 framing by entering the framing {c-bit | m13 | bypass}
configuration subcommand, as in the following example:
router(config-if)# framing c-bit
Use the no form of this command to return to the default, which is C-bit framing.
Note If you use the bypass option, scrambling must be set to the default, disabled; the DSU mode
must be set to the default, 0; and the DSU bandwidth must be set to the default, 44210.
Setting the Cable Length
In interface configuration mode, set the cable length (range of 0 to 450 feet), as in the following
example:
router(config-if)# cablelength 250
Use the no form of this command to return to the default, which is 10 feet.
Configuring Cyclic Redundancy Checks
The PA-T3 serial port adapter uses a 16-bit CRC by default; it also supports a 32-bit CRC.
CRC is an error-checking technique that uses a calculated numeric value to detect errors in
transmitted data. The sender of a data frame divides the bits in the frame message by a predetermined
number to calculate a remainder or frame check sequence (FCS). Before sending the frame, the
sender appends the FCS value to the message so that the frame contents are exactly divisible by the
predetermined number. The receiver divides the frame contents by the same predetermined number
that the sender used to calculate the FCS. If the result is not 0, the receiver assumes that a
transmission error occurred and sends a request to the sender to resend the frame.
Note To enable 32-bit CRC on an interface, follow Steps 1 and 2 of the preceding procedure (enter
configuration mode and specify the slot and port address [and the interface port number for a VIP2]
of the PA-T3 serial port adapter), and then enter the command crc 32. Enter Ctrl-Z to exit from
configuration mode.
Configuring the PA-T3 Interfaces 8-13
Checking the Configuration
For a Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series router, use the following
example:
router# configure terminal
Enter configuration commands, one per line.
router(config)#
router(config)# interface serial 3/0
router(config-int)# crc 32
Ctrl-z
End with CNTL/Z.
For a VIP2, use the following example:
router# configure terminal
Enter configuration commands, one per line.
router(config)#
router(config)# interface serial 1/0/0
router(config-if)# crc 32
Ctrl-z
End with CNTL/Z.
For a Catalyst RSM/VIP2, use the following example:
router# configure terminal
Enter configuration commands, one per line.
router(config)#
router(config)# interface serial 0/0
router(config-if)# crc 32
Ctrl-z
End with CNTL/Z.
To disable CRC-32 and return to the default CRC-16 setting, specify the slot and port address (and
the interface port number for a VIP2) and use the no crc 32 command. For complete command
descriptions and instructions, refer to the related software documentation.
Note When enabling a 32-bit CRC on an interface, ensure that the remote device is also configured
for a 32-bit CRC. Both the sender and the receiver must use the same CRC setting.
To check the interface configuration using show commands, proceed to the following section,
“Checking the Configuration.”
Checking the Configuration
After configuring the new interface, use the show commands to display the status of the new
interface or all interfaces, the ping command to check connectivity, and the loopback command to
troubleshoot the physical interface.
Using show Commands to Verify Status
Use the show commands to verify that the new interfaces are configured and operating correctly:
8-14
Step 1
Use the show version command to display the system hardware configuration. Ensure
that the list includes the new interfaces.
Step 2
Display all the current port adapters and their interfaces with the show controllers
command. Verify that the new PA-T3 serial port adapter appears in the correct slot.
PA-T3 Serial Port Adapter Installation and Configuration
Using show Commands to Display Interface and System Information
Step 3
Step 4
Specify one of the new interfaces:
•
For Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers, specify
one of the new interfaces with the show interfaces type port adapter slot/interface
command, and verify that the first line of the display specifies the interface with the
correct slot number. Also verify that the interface and line protocol are in the correct
state: up or down.
•
For a VIP2, specify one of the new interfaces with the show interfaces type slot/port
adapter/interface command, and verify that the first line of the display specifies the
interface with the correct slot number. Also verify that the interface and line protocol
are in the correct state: up or down.
•
For a Catalyst RSM/VIP2, specify one of the new interfaces with the show interfaces
port adapter/interface command, and verify that the first line of the display specifies
the interface with the correct slot number. Also verify that the interface and line
protocol are in the correct state: up or down.
Specify the new serial interface:
•
For Cisco 7100 series, Cisco 7200 series, Cisco uBR7200 series routers, specify the
new serial interface with the show controllers serial port adapter slot
number/interface port number command, and verify that the first line of the display
specifies the interface with the correct slot number.
•
For a VIP2, specify information that is specific to the new serial interface with the
show controllers serial slot/port adapter/interface command, and verify that the first
line of the display specifies the interface with the correct slot number.
•
For a Catalyst RSM/VIP2, specify information that is specific to the new serial
interface with the show controllers serial port adapter/interface command, and
verify that the first line of the display specifies the interface with the correct slot
number.
Step 5
Display the protocols configured for the entire system and for the specific interfaces with
the show protocols command. If necessary, return to configuration mode to add or
remove protocol routing on the system or on specific interfaces.
Step 6
Display the running configuration file with the show running-config command. Display
the configuration stored in NVRAM using the show startup-config command. Verify
that the configuration is accurate for the system and each interface.
If the interface is down and you configured it as up, or if the displays indicate that the hardware is
not functioning properly, ensure that the network interface is properly connected and terminated. If
you still have problems bringing the interface up, ask a service representative for assistance.
Using show Commands to Display Interface and System Information
For a Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series router, to display information
about a specific interface, use the show interfaces command with the interface type and port address
in the format show interfaces [type slot/port].
Configuring the PA-T3 Interfaces 8-15

For Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers, use the
show controllers command to display all the current interface processors and their interfaces.
Following is an example of the show controllers command that shows serial port 2/0 on a one-port
PA-T3 serial port adapter installed in chassis slot 2 for a Cisco 7200 series router:
router# show controllers 2/0
M1T-Serial: show controller:

(Additional display text omitted from this example.)
For Cisco 7100 series, Cisco 7200 series, Cisco uBR7200 series routers, use the show controllers
serial command, using arguments such as the slot and port number (slot/port), to display information
that is specific to the serial interface hardware. Following is an example of the show controllers
serial slot/port command that shows the serial port adapter installed on a Cisco 7200 series router
in chassis slot 3:

Configuring the PA-T3 Interfaces 8-23
Checking the Configuration
For complete command descriptions and examples for the Cisco 7100 series routers, Cisco 7200
series routers, Cisco uBR7200 series routers, VIP2 and Catalyst RSM/VIP2, refer to the
publications listed in the “Related Documentation” section on page vi.
Using the ping Command to Verify Network Connection
The ping command allows you to verify that an interface port is functioning properly and to check
the path between a specific port and connected devices at various locations on the network. After you
verify that the system has booted successfully and is operational, you can use the ping command to
verify the status of interface ports. Refer to the publications listed in the “Related Documentation”
section on page vi for detailed command descriptions and examples.
The ping command sends an echo request out to a remote device at an IP address that you specify.
After sending a series of signals, the command waits a specified time for the remote device to echo
the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal;
each signal that is not returned before the specified timeout is displayed as a period (.). A series of
exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the message [timed
out] or [failed] indicates that the connection failed.
Following is an example of a successful ping command to a remote server with the address 10.0.0.0:
router# ping 10.0.0.0 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.0.0.0, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
router#
If the connection fails, verify that you have the correct IP address for the server and that the server
is active (powered on), and repeat the ping command. Refer to the publications listed in the “Related
Documentation” section on page vi for complete descriptions of interface subcommands and the
available configuration options.
Using the loopback Command to Verify the Physical Interface
Use the loopback {dte | local | network {line | payload} | remote} command to troubleshoot the
PA-T3 serial port adapter at the physical interface level. The command loops all packets from the
PA-T3 interface either back to the interface or from the network back out toward the network. Use
the no form of the command to remove the loop.
The following examples of the loopback {dte | local | network {line | payload} | remote} command
configure loopback modes on serial port 0 of a one-port PA-T3 serial port adapter installed in chassis
slot 6 of a Cisco 7200 series router:
•
Set the interface into loopback data terminal equipment (DTE) mode as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 6/0
router(config-if)# loopback dte
Loopback DTE loops the router output data back toward the router (after the line interface unit
[LIU]).
8-24
PA-T3 Serial Port Adapter Installation and Configuration
Using the loopback Command to Verify the Physical Interface
•
Set the interface into local loopback mode as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 6/0
router(config-if)# loopback local
Local loopback loops the router output data back toward the router at the framer.
•
Set the interface into network line loopback mode as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 6/0
router(config-if)# loopback network line
Network line loopback loops the data back toward the network (before the framer).
•
Set the interface into network payload loopback mode as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)# interface serial 6/0
router(config-if)# loopback network payload
Network payload loopback loops just the payload data back toward the network at the PA-T3
framer.
•
Set the interface into remote loopback mode as follows:
Router# configure terminal
Enter configuration commands, one per line.
router(config)# interface serial 6/0
router(config-if)# loopback remote
End with CNTL/Z.
Remote loopback loops the data back toward the network (before the framer at the remote
T3 device).
Note Remote loopback mode works with C-bit framing only. The other loopback modes listed
above work with C-bit, M13, and bypass framing. See the “Specifying T3 Framing” section on
page 8-13 for information on configuring C-bit framing.

Depending on your circumstances, you might need to install a new port adapter in a Cisco 7100
series router or replace a failed port adapter in the field. All port adapters available for the Cisco 7100
series connect directly to the router and are locked into position by a locking tab with two screws
(see Figure 7-1 or Figure 7-2). You need a number 2 Phillips screwdriver to loosen the screws.
Note The Cisco 7100 series routers support online insertion and removal (OIR); therefore, you do
not have to power down the router when removing and replacing a port adapter.
When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router
to conform to EMI emissions requirements and to allow proper airflow across the port adapters. If
you plan to install a new port adapter in a slot that is not in use, you must first remove a blank port
adapter.
Removing a Port Adapter
Following is the procedure for removing a port adapter from a Cisco 7100 series router:
Step 1
Attach an ESD-preventive wrist strap between you and the chassis. See Figure 7-1 or
Figure 7-2 for the location of the ESD plug.
Step 2
Use a number 2 Phillips screwdriver to loosen the screws on the locking tab; then slide
the tab down to the unlocked position. (See Figure 7-1 or Figure 7-2.)
Step 3
Grasp the handle on the port adapter and pull the port adapter from the router, about
halfway out of its slot. If you are removing a blank port adapter, pull the blank port
adapter completely out of the chassis slot.
Note As you disengage the port adapter from the router, OIR administratively shuts
down all active interfaces on the port adapter.
Step 4
With the port adapter halfway out of the slot, disconnect all cables from the port adapter.
Step 5
After disconnecting the cables, pull the port adapter from its chassis slot.
Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter’s
components or connector pins. (See Figure 7-3.)

Step 6
Place the port adapter on an antistatic surface with its components facing upward, or in a
static shielding bag. If the port adapter will be returned to the factory, immediately place
it in a static shielding bag.
Step 7
Install a blank port adapter or replacement port adapter to maintain proper flow of cooling
air across the internal components. For procedures on how to install a port adapter, see
the next section, “Installing a Port Adapter.”
Note The blank port adapter is available from Cisco Systems as a spare. The blank port
adapter product number is MAS-7100-PABLANK.
This completes the procedure for removing a port adapter from a Cisco 7100 series router.
Installing a Port Adapter
Following is the procedure for installing a new port adapter in a Cisco 7100 series router:
Step 1
Attach an ESD-preventive wrist strap between you and the chassis. See Figure 7-1 for the
location of the ESD plug.
Step 2
Ensure that the locking tab is down in the unlocked position. If it is locked, use a
number 2 Phillips to loosen the screws; then slide the tab down to the unlocked position.
(See Figure 7-1 or Figure 7-2.)
Step 3
Remove the new port adapter from its antistatic container and position it at the opening
of the slot.
Step 4
Use both hands to grasp the port adapter by its metal carrier edges, and position the port
adapter so that its components face downward. (See Figure 7-3.)
Step 5
Align the left and right edge of the port adapter metal carrier between the guides in the
port adapter slot. (See Figure 7-4.)
Step 6
With the metal carrier aligned in the slot guides, gently slide the port adapter halfway into
the slot.
Caution Do not slide the port adapter all the way into the slot until you have connected all required cables.
Trying to do so disrupts normal operation of the router.

Step 7
With the port adapter halfway in the slot, connect all required cables to the port adapter.
Step 8
After connecting all required cables, carefully slide the port adapter all the way into the
slot until the port adapter is seated in the router.
Step 9
After seating the port adapter in the router, slide the locking tab up to the locked position
and tighten the screws. (Figure 7-1 or Figure 7-2 shows the locking tab in the locked
position.)
Note If the port adapter lever is not in the locked position, the port adapter is not
completely seated in the router. Carefully pull the port adapter halfway out of the slot,
reinsert it, and move the port adapter lever to the locked position.
This completes the procedure for installing a new port adapter in a Cisco 7100 series router. Proceed
to Chapter 8, “Configuring the PA-T3 Interfaces,” for information on configuring your port adapter
interfaces.
