¹MFSC = Multilayer Switch Feature Card
²The PA-T3+ is considered a high-bandwidth port adapter. The specific VIP2 model recommended for the PA-T3+ in all Cisco 7000 series routers using the RSP7000 and RSP7000CI is the VIP2-15, which has 1 MB of SRAM and 8 MB of DRAM. Installation of the PA-T3+ on the VIP2-10 (with 512 KB of SRAM and 8 MB of DRAM) is not recommended.
³The PA-T3+ is considered a high-bandwidth port adapter. The specific VIP2 model recommended for the PA-T3+ in all Cisco 7000 series routers using the RSP7000 and RSP7000CI is the VIP2-15, which has 1 MB of SRAM and 8 MB of DRAM. Installation of the PA-T3+ on the VIP2-10 (with 512 KB of SRAM and 8 MB of DRAM) is not recommended.
⁴The VIP4 provides 64 or 256 MB of 100-MHz synchronous dynamic random-access memory (SDRAM) as the central processing unit (CPU) memory (also called program memory), and 64 of 100-MHz SDRAM as the packet memory

Caution The VIP requires that the host Cisco 7000 series router have the RSP7000 and RSP7000CI installed. The VIP will not operate properly with the Route Processor (RP), Switch Processor (SP), or Silicon Switch Processor (SSP) installed in the host Cisco 7000
series router.

For Cisco configuration guidelines in the Cisco 7200 series, refer to the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines.

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:

Checking Hardware and Software Compatibility

To check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether modules within a system are compatible, but it does provide the minimum IOS requirements for individual hardware modules or components.

Note Access to this tool is limited to users with Cisco.com login accounts.

To access Software Advisor, click Login at Cisco.com and go to Technical Support Help—Cisco TAC: Tool Index: Software Advisor. You can also access the tool by pointing your browser directly to http://www.cisco.com/cgi-bin/support/CompNav/Index.pl.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Before beginning any procedure requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
Disconnect all power and external cables before moving a chassis; do not work alone when potentially hazardous conditions exist.
Never assume that power has been disconnected from a circuit; always check.
Do not perform any action that creates a potential hazard to people or makes the equipment unsafe; carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

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 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 protects components from ESD voltages on the body only; 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).
