Field Notice: Cisco 7200/VIP2 Series Ethernet Port Adapter


Revised July 31, 1998

September 17, 1997


NOTICE:

THIS FIELD NOTICE IS PROVIDED ON AN "AS IS" BASIS AND DOES NOT IMPLY ANY KIND OF GUARANTEE OR WARRANTY, INCLUDING THE WARRANTY OF MERCHANTABILITY. YOUR USE OF THE INFORMATION ON THE FIELD NOTICE OR MATERIALS LINKED FROM THE FIELD NOTICE IS AT YOUR OWN RISK. CISCO RESERVES THE RIGHT TO CHANGE OR UPDATE THIS FIELD NOTICE AT ANY TIME.

Products Affected

This field notice affects Cisco 7200/VIP2 systems using a specific hardware revision of one of the following Ethernet port adapters:

  • PA-4E(=)

  • PA-5EFL(=)

  • PA-8E(=)

Overview

A problem has been found that affects a specific hardware version of Ethernet port adapters installed in Cisco 7200/VIP2 systems. This condition can cause one of the described failures in Cisco 7200/VIP2 systems.

Note: Originally, this field notice was written specifically for the 7200 platform, but similar problems are now known to happen on VIP-based units. In either case, follow the upgrade path to the latest port adapter hardware revision.

Note: PA-4E and PA-8E Ethernet port adapters that are hardware revision 1.11 or PA-5EFL Ethernet port adapters that are hardware revision 1.2 may cause Cisco 7200/VIP2 systems to reload.

Problem Symptoms

Cisco 7200/VIP2 systems with one or more PA-4E and PA-8E hardware revision 1.11 or PA-5EFL hardware revision 1.2 Ethernet port adapters may exhibit one of the following symptoms:

  • System restarted by power-on

    A Cisco 7200/VIP2 system may reload with no information left in the fault history buffer. The only information available is through the show version Cisco IOS command, indicating that a system reload occurred due to a power-on condition. Below is an example of the output of the show version command illustrating this:

    Router uptime is 2 days, 19 hours, 58 minutes
      System restarted by power-on at 01:19:00 UTC Sun Mar 9 1997
      System image file is "slot0:c7200-inu-mz.111-8.CA1.bin", booted via slot0
    

    This is the most common symptom and is most likely to occur under heavy traffic loads.

  • PCI parity error

    A system reload may also occur on light to moderately loaded Cisco 7200/VIP2 routers. In this case, the symptoms are quite different. The router reloads with a PCI parity error or an error interrupt, for example:

    ERR-1-SERR: PCI bus system/parity error
     %ERR-1-FATAL: Fatal error interrupt, reloading
     err_stat=0x0, err_enable=0xFF, mgmt_event=0x8
    
     *** System received an Error Interrupt ***
     signal= 0x16, code= 0x0, context= 0x60997fa0

     0x6010dc54:r4k_sig_dispatch_return(0x6010dbfc)+0x58
    
  • Error interrupt

    A Cisco 7200/VIP2 system reload may also occur with the following error:

    System was restarted by error - an Error Interrupt, PC 0x600267A0

  • Fault history buffer error

    A Cisco 7200/VIP2 system reload may also occur with the following error:

Workaround/Solution

Hardware changes have been made to the Ethernet port adapters that correct the issues described above. Cisco strongly recommends that customers with Cisco 7200/VIP2 systems upgrade all PA-4E and PA-8E adapters with hardware version 1.11 to hardware version 1.12 or later, and upgrade PA-5EFL adapters with hardware version 1.2 to hardware version 1.3 or later.

Beginning September 9, 1997, customers may obtain replacement PA-4E and PA-8E hardware version 1.12 or PA-5EFL hardware version 1.3 Ethernet port adapters on a port-for-port basis at no charge through Cisco's Technical Assistance Center (TAC).

Revised PA-4E, PA-5EFL, and PA-8E port adapters can be distinguished using the show diag Cisco IOS command. Revised PA-4E, PA-5EFL, and PA-8E port adapters can be identified by the following part numbers:

Port Adapter

New Revision Level

PA-4E

PN 73-1556-07 Rev. A0 HW-V 1.12 or later
