Software and Hardware Requirements

Table 2-1 lists the recommended minimum Cisco IOS software release required to use the PA-T3 in supported router or switch platforms.

¹MSFC = Multilayer Switch Feature Card

Caution

The VIP requires that the host Cisco 7000 series router have the RSP7000 and RSP7000CI installed. The VIP 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.

Note The VIP, the Catalyst RSM/VIP2, the Catalyst 6000 family FlexWAN module,and the Cisco 7304 PCI Port Adapter Carrier Card support 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, the Catalyst 5000 family switches, the Catalyst 6000 family switches, and the 7304 router, you must first remove the VIP, the Catalyst RSM/VIP2, the Catalyst 6000 family FlexWAN module, or the Cisco 7304 PCI Port Adapter Carrier Card from the chassis and then replace port adapters as required. OIR is supported for port adapters in the Cisco 7100 series, Cisco 7200 series, Cisco uBR7200 series routers, and the Cisco 7401ASR routers. Port adapters have a handle attached, but this handle is occasionally not shown in the illustrations of this publication to allow a full view of detail on the port adapter faceplate.

In the Cisco 7000 series, Cisco 7100 series, Cisco 7500 series, Cisco uBR7200 series routers, Cisco 7301 routers, the Cisco 7401ASR 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, Cisco uBR7200 series router, Cisco 7301 router, or Cisco 7401ASR 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.

Interoperability Guidelines for PA-T3 Serial Port Adapter DSUs

The PA-T3 serial port adapter supports several types of integrated DSUs. Table 2-2 lists the feature compatibilities of the PA-T3 serial port adapter DSUs.

Table 2-2 Feature Compatibilities of PA-T3 Serial Port Adapter
DSU	Full Rate Support	Scrambling Support	Subrate Support	MDL ¹ Support
DL3100	Yes	Yes	Yes	No
Kentrox	Yes	Yes²	Yes²	No
Larscom	Yes	Yes	Yes	No

¹MDL=Maintenance Digital Link.

²PA-T3 serial port adapters support either scrambling or Kentrox subrate, not both at the same time.

75-Ohm In-Line Coaxial Attenuator

A 75-ohm in-line coaxial attenuator may be required to tune the signal between the PA-T3 and the far-end equipment, if the port adapter is experiencing line code violations (LCVs). LCVs occur when the far end equipment transmit signal saturates the front end receiver of the PA-T3.

Cisco offers an attenuator kit (ATTEN-KIT-PA=) that contains five attenuators with fixed values ranging from 3-dB to 20-dB. For more information on the attenuator kit go to the following website:

http://www.cisco.com/univercd/cc/td/doc/product/core/7206/fru/12884att.htm

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 work alone when potentially hazardous conditions exist.

•Never assume that power has been disconnected from a circuit; always check.

•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe; carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

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 improperly handled, results in complete or intermittent failures. Port adapters and processor modules comprise 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).
