1The Catalyst RSM/VIP2 model recommended for the PA-A3 is the VIP2-40, which has 2 MB of SRAM and 32 MB of DRAM. The PA-A3 is not supported by the VIP2-15.
2Currently, the Cisco uBR7246 VXR router supports only the PA-A3-OC3MM, PA-A3-OC3SMI, and PA-A3-OC3SML port adapters. In the future, however, the Cisco uBR7246 VXR will support both the PA-A3-E3 and PA-A3-T3 port adapters.

Note Although PA-A3 port adapters purchased or received before November 1998 and installed on the VIP2, might continue to function properly in Cisco 7500 series and Cisco 7200 series software releases before Cisco IOS Release 11.1(22)CC, you must upgrade to Cisco IOS Release 11.1(22)CC. This release can be ordered as Release 11.1(22)R to ensure software release consistency throughout your network and to prevent problems when you add new PA-A3 port adapters to your existing network.

You must use Cisco IOS Release 12.0(1) or later on the Catalyst RSM/VIP2.
Caution All PA-A3 port adapters shipped after November 1998 require Cisco IOS Release 11.1(22)CC or a later release of Cisco IOS Release 11.1 CC to operate; they do not function on any software release before Release 11.1(22)CC.
Note When you upgrade your Cisco IOS software to the minimum required software release, we recommend you also upgrade your boot image.

The boot image for your upgraded Cisco IOS software release is available on CCO. For information on how to access CCO, see the "Obtaining Technical Assistance" section. Instructions for downloading the boot image from a TFTP server are described in the "Upgrading Your Boot Flash Image" section.

To determine which revision of the PA-A3 is installed, use the show diag command. PA-A3 port adapters identified with board revision B0 require a minimum software release of Cisco IOS Release 11.1(22)CC for Cisco 7500 series and Cisco 7200 series routers.

The following example shows the new board revision number (B0) for a PA-A3-OC3MM port adapter installed in slot 1:

router# show diag 1
Slot 1:
         ATM WAN OC3 (MM) port adapter, 1 port
         Port adapter is analyzed 
         Port adapter insertion time 22:36:49 ago
         Hardware revision 1.0           Board revision B0

To determine if your router is compatible with the PA-A3, 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. The show controllers command lists all interfaces (VIP2, VIP4, and Catalyst RSM/VIP2 only) and gives the currently loaded and running microcode version for each. You can check the version of the default ROM image by either 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 these same commands to check the running version.

If a display indicates that the running system software is an earlier version than Cisco IOS Release 11.1(22)CC on a Cisco 7500 series, Cisco 7000 series, or Cisco 7200 series router, check the contents of Flash memory to determine whether the required images are available on your system. (Use the show flash command to display a list of all files stored in Flash memory.)

On a Cisco 7000 series or Cisco 7500 series router with a VIP4, you must be running Cisco IOS Release 12.0(10)S or later. On the Catalyst RSM/VIP2, you must be running Cisco IOS Release 12.0(1) or later.

In the following example of the show version command on a Cisco 7200 series router, the running system software is Cisco IOS Release 11.1(22)CC:

%ATMPA-3-PCIMEMNOTENOUGH: Not Enough PCI memory (0x19874) to support ATM PA on bay 5
After you replace port adapters several times using online insertion and removal (OIR), SRAM on Cisco 7200 series routers becomes fragmented. When this happens, the system might not be able to find enough contiguous SRAM to complete initialization at bootup, and you might get an error message that there is not enough memory. If you have been using the OIR feature numerous times and you get a memory error message during initialization of a PA-A3, we recommend that you power off and restart the system.
The PA-A3 and Cisco 7200 routers and Cisco uBR7200 series routers' network processor memory configurations include the following:

VIP2 and VIP4 in Cisco 7000 Series and Cisco 7500 Series

Laser/LED Safety Guidelines

The single-mode transmitter in the PA-A3-OC3SMI and PA-A3-OC3SML uses a small laser to transmit the light signal to the network ring. Keep the transmit port covered whenever a cable is not connected to it. Although multimode transceivers typically use LEDs for transmission, it is good practice to keep open ports covered and avoid staring into open ports or apertures.

The single-mode aperture port contains a Class 1 laser warning label, as shown in Figure 2-1.


Figure 2-1: Class 1 Laser Warning Label on PA-A3-OC3SMI and PA-A3-OC3SML


Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures.
Warning Class 1 laser product.

The multimode aperture contains a Class 1 LED warning label, as shown in Figure 2-2.


Figure 2-2: Class 1 LED Warning Label on PA-A3-OC3MM


Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures.
Warning Class 1 LED product.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:

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:

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:

Note The PA-A3 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.

ITU-T Compliance

ITU-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-A3 port adapter's line mode clocking complies with these sections.

CTR Compliance

The PA-A3 port adapters comply with European CTR standards.
