Port adapter is not supported in a Cisco 7200 VXR chassis due to early hardware revision

Core Issue

A port adapter which operates properly in a Cisco 7200 non-VXR chassis may display error messages similar to this if placed in a VXR chassis:

  • In the system logs:

    %PA-3-REVNOTSUPPORTED: PA in slot2 (Ethernet) requires base h/w revision

    of (1.14) for this chassis

    %PA-3-NOTSUPPORTED: PA in slot2 (Ethernet) is not supported on this chassis

  • In a show diag command output:

    Port adapter is disabled unsuitable deactivated powered off

This is due to the new and higher speed Peripheral Component Interconnect (PCI) midplane on a VXR chassis requiring an upgrade to the port adapter's arbiter Erasable Programmable Logic Device (EPLD). Certain port adapters will not function properly in a VXR chassis unless this upgrade is performed.

Resolution

To identify the port adapter's hardware revision, issue the show diag command. This example shows the port adapter in slot1:

Router#show diag 1
Slot 1:
        Channelized T1 port adapter, 2 ports
        Port adapter is disabled unsuitable deactivated powered off
        Port adapter insertion time unknown
        EEPROM contents at hardware discovery:
        Hardware revision 1.1           Board revision A0
        Serial number     5105485       Part number    73-1565-05
        Test history      0x0           RMA number     00-00-00
        EEPROM format version 1
        EEPROM contents (hex):
          0x20: 01 07 01 01 00 4D E7 4D 49 06 1D 05 00 00 00 00
          0x30: 50 00 00 00 97 05 31 00 FF FF FF FF FF FF FF FF

For a list of supported revisions, port adapters which are not supported on the VXR chassis, and instructions for obtaining an upgraded port adapter, refer to Field Notice: Port Adapter Compatibility for Cisco 7200 VXR Routers.

Any Idea why this message would show in the logs even though the card IS supported and the show diag indicates that it is working fine?
