The %PA-2-UNDEFPA: Undefined Port Adapter type [num] in bay [num] messages occur at bootup and boot image does not recognize a port adapter


Core Issue

This message may occur during bootup, yet after the full Cisco IOS  Software image is loaded, the port adapter is recognized and functioning properly.

This usually occurs because the the boot image is at a version level which does not support the port adapter, while the full Cisco IOS image is at a version level which does support the port adapter. This does not hinder the router's performance in any way while the router is up and running the full Cisco IOS version. If the router is in boot mode, however, the port adapter will not be available.


To eliminate the bootup message, perform these steps:

  1. Identify the port adapter by issuing the show diag command. This determines which port adapter is in the bay (slot), which is referenced by the error message.  


    If the error message is %PA-2-UNDEFPA: Undefined Port Adapter type 549 in bay 3, the port adapter shows up in slot 3 in the show diag output, as shown:

    router#show diag
    Slot 3:
             Dual Port FastEthernet (RJ45) Port adapter, 2 ports
             Port adapter is analyzed
             Port adapter insertion time 1d08h ago
             EEPROM contents at hardware discovery:
             Hardware Revision        : 1.0
             PCB Serial Number        : MPC0527006A

               0x60: FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF
               0x70: FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF

    This output shows that the port adapter is a PA-2FE-TX.


  2. Identify the version of the boot image by issuing the show version command, as shown:  

    router#show version
    Cisco Internetwork Operating System Software
     IOS (tm) 7200 Software (C7200-JS-M), Version 12.1(9)E3, EARLY
     TAC Support:
     Copyright (c) 1986-2002 by cisco Systems, Inc.
     Compiled Mon 11-Feb-02 23:57 by eaarmas
     Image text-base: 0x60008950, data-base: 0x614F2000
     ROM: System Bootstrap, Version 11.1(5) [mkamson 5], RELEASE SOFTWARE
     BOOTLDR: 7200 Software (C7200-BOOT-M), Version 12.0(21), RELEASE
    SOFTWARE (fc1)
     DRDFAS02 uptime is 1 day, 8 hours, 50 minutes
     System returned to ROM by reload at 08:28:15 UTC Sun Apr 14 2002
     System restarted at 08:30:04 UTC Sun Apr 14 2002
     System image file is "slot0:c7200-js-mz.121-9.E3.bin"

    The version is 12.0(21). This is shown in this output in the BOOTLDR: line.


  3. To list the file(s) in bootflash if the show version command output does not list the boot image version, issue the dir bootflash: command, as shown:  

    router#dir bootflash:
     -#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------name
     1   .. image    F8E69CED  2AA7D8   24  2533208 Mar 28 2002 22:56:39 c7200-boot-mz.120-21.bin

  4. Once the hardware and current boot image have been identified, refer to the Software Support for Hardware section of the Software Advisor. This determines the minimum software version requirements for the port adapter.  

  5. Upgrade the boot image to the same version level as the main Cisco IOS image by referring to the Upgrading the Boot Helper Image section of Preparing for Installation.  


    While matching the versions is not critical, it may eliminate other informational messages at bootup, which are caused by different boot and main Cisco IOS versions.


When Problem Occurs

After hardware installation or replacement

After reboot or power cycle (and no other changes)
