7600-SIP-200 being shut down

I have a 7600 that is shutting down the 7600-SIP-200. I have replaced the7600-SIP-200, but I still get the below errors when I do show commands:

LONPWGPR2#show diagnostic event

Does this mean that there is a bus failure and the chassis needs replacing ?

Re: 7600-SIP-200 being shut down


Symptoms: The following issues are observed:

All egress traffic by SIP-400 is dropped.

Consecutive BusConnectivityTest failure for SIP-400.

When SIP-400 is hosting intelligent SPAs such as SPA-8XCHT1/E1, then this SPA gets into

OutSrvc state.

Conditions: The symptom is observed with a SIP-400 with egress LLQ shaping and with a high

volume of traffic to low speed stream.

Workaround 1: SIP-400 reload using the hw-module module X reset command (where X is the

module/SIP-400 number).

Workaround 2: Remove LLQ configuration.

Workaround 3: SIP-400 microcode reload (where X is the module/SIP-400 number):

attach X


microcode reload np



WARNING: The following port(s) on Switch  module 2 have failed the BusConnectivityTest


This is a disruptive test and runs automatically during bootup and Health monitoring

test except for the Flex WAN and CIP400 modules where is only runs on bootup. This

test is available for WAN linecards.

This test failure usually indicates a problem with the connection between the linecard

And the supervisor module.


* Inspect the backplane connector on the module  to make sure it is not

  damaged. If there is no visual damage, try the module in another slot

  or a different chassis. Also, inspect for bent pins on the slot connector

  on the backplane. You may want to use a flashlight when you inspect the

  connector pins on the chassis backplane.

* If the problem continues to occur, turn on the debug diagnose error

  trace to further troubleshoot the problem and determine if this module

  needs to be replaced.
