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-E3 is considered a high-bandwidth port adapter; therefore at a minimum, Cisco recommends that the PA-E3 be installed on the VIP2-15 or Catalyst RSM/VIP2-15 motherboard (with 1 MB of SRAM and 16 MB of DRAM). Installation of the PA-E3 on the VIP2-10 (with 512 KB of SRAM and 8 MB of DRAM) is not recommended.

Note The VIP2, VIP4, and Catalyst RSM/VIP2 supports online insertion and removal (OIR), but individual port adapters do not. To replace the port adapters, you must first remove the VIP2, VIP4, 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, Cisco uBR7200 series routers and Catalyst 5000 family 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 hardware configuration information and for memory configuration guidelines for Cisco 7200 series routers, 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 the Catalyst RSM/VIP2 is compatible with the PA-E3, 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.
To display the current system software version, use the show version command. In the following example, the running system software is Release 11.1(16)CA.

Follow these basic guidelines when working with any electrical equipment:
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.
The following are guidelines for preventing ESD damage:
![]() |
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohm). |
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:

Note The PA-E3 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. |
The BABT607116 marking on the PA-E3 signifies that it meets United Kingdom directive 607116 and has been designed to BABT standards. The BABT label is located on the top of the PA-E3; shows the BABT label for the PA-E3.

ITI-T recommendation G.823 specifies that it is important to restrict jitter gain. Figure 4 of G.823 shows a typical jitter transfer characteristic. (Note that small jitter gain is allowed.) British Standard 6328: Section 8.1 1990 gives the allowable gain as 0.5 dB. The PA-E3 line mode clocking complies with these sections.
When the PA-E3 is in line clocking mode, jitter is not attenuated, and any jitter received is transferred to the line. If input jitter exceeds the limits of TBR24, then output jitter will not meet TBR24 transfer specifications. Line clocking mode is intended for use only where the connection involves a single hop, and where clock timing will not be transferred to other network equipment.
When not in line clocking mode, the PA-E3 complies with TBR24 standards.
