This chapter describes the one-port PA-T3 and two-port PA-2T3 serial port adapters. This chapter contains the following sections:

• Port Adapter Overview, page 1-1

• PA-T3 Serial Port Adapter Features, page 1-2

• Management Information Base, page 1-3

Port Adapter Overview

The PA-T3 serial port adapter is a single-width, one-port or two-port module that integrates data service unit (DSU) functionality into the Cisco router. It provides one or two high-speed serial PA-T3 interfaces on Cisco 7100 series routers, Cisco 7200 series routers, Cisco uBR7200 series routers, on the second-generation Versatile Interface Processor (VIP2) in all Cisco 7000 series and Cisco 7500 series routers, and on the Catalyst RSM/VIP2 in the Catalyst 5000 series switches. (See Figure 1-1 and Figure 1-2.)

Note Port adapters have a handle attached, but this handle is occasionally not shown in ﬁgures in

this publication to allow a full view of detail on the port adapter’s faceplate.

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-T3interface 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-bitCRCs;toenable 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 Cisco7000 series and Cisco 7500 series routers, and the Catalyst 5000 series switches, you must ﬁrst removethe 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-T3port 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-T3serial 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 from Cisco Systems; it is not available from outside commercial cable vendors.

The Cisco PA-T3 75-ohm coaxial cable (see Figure 2-3) is available only in 10-foot (3.05-meter) lengths. The typical maximum distance between stations for PA-T3 transmissions is 1300 feet (396 meters).

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Electrical Equipment Guidelines

• 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 work alone when potentially hazardous conditions exist and 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.

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 install telephone jacks in wet locations unless the jack is speciﬁcally designed for wet

locations.

• 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.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperlyhandled,resultsincompleteorintermittentfailures.Portadaptersandprocessormodules 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.

• 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.

• 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.

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.

PA-T3 Serial Port Adapter Installation and Configuration

FCC Class A Compliance

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That

is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Note The PA-T3 serial port adapter has been designed to meet these requirements. Modiﬁcations

to this product that are not authorized by Cisco Systems, Inc., could void the various approvals and negate your authority to operate the product.

CHAPTER

VIP2 and the PA-T3 Port Adapter

This chapter provides information on the PA-T3 port adapter and its use on the VIP2 in Cisco 7000 series and Cisco 7500 series routers. This chapter contains the following sections:

• Overview, page 3-1

• Removing a Port Adapter, page 3-4

• Installing a Port Adapter, page 3-5

Overview

The PA-T3 serial port adapter is used on the VIP2 in Cisco 7000 series and Cisco 7500 series routers and can be installed in either port adapter slot 0 or slot 1 on the VIP2 motherboard.

Note You can have up to three T3 serial interfaces on a VIP2 motherboard. Cisco recommends a

conﬁguration of one PA-T3 serial port adapter (with one T3 serial interface) and one PA-2T3 serial port adapter (with two serial interfaces) for a total of three T3 serial interfaces per VIP2.

Figure 3-1 shows two one-port PA-T3 serial port adapters installed in port adapter slot 0 and slot 1 on a VIP2-15 or VIP2-40.

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.
