Problem Description

A 7500 chassis with a Chassis Interface board (MAS-7500CI=) that falls within the affected Serial Numbers will cause continuous error messages to the console, resulting in the console to be unusable. Refer to Problem Symptom below for specific details of the what error messages appear on the console.

Background

The affected Chassis Interface boards were built and shipped with an incorrect component. Cisco has isolated the affected boards to the Serial Numbers listed above.

Problem Symptoms

During an IOS boot-up, affected 7500 Chassis Interface Boards will show the following error message and traceback on the console continuously:

%CI-3-NOACK: address acknowledge failure, cmd 10, addr 00, data 00

-Traceback= 6031EF88 60322E30 602714A0 60271548 601E7558 601E7710 60257CCC 60257CB8 00:00:29:

%CI-3-NOACK: address acknowledge failure, cmd 10, addr 01, data 00

%CI-3-NOACK: address acknowledge failure, cmd 90, addr 00, data 00 -

Workaround/Solution

Workaround:

None

Solution:

Affected units can be identified by the serial number of the Chassis Interface Board, refer to How to Identify Hardware Levels below for instructions on how to view the Serial number.

Confirm the Serial number is within the affected Serial Numbers list specified above.

Once that is confirmed, request a replacement through the RMA process.

Once you have received your replacement, follow these instructions on Replacing the Chassis Interface (CI) Board in the Cisco 7500 Series Chassis.

How To Identify Hardware Levels

The Chassis Interface Board can be identified using the show diagnostic command from the Command Line Interface:

CISCO7507MX# show diag 31
Slot 31 (virtual):
EEPROM format version 1
Chassis Interface, HW rev 1.01, board revision E0
Serial number: 32025689  Part number: 73-1306-02    < <  = = =   Serial number located here
Test history: 0x00        RMA number: 00-00-00
Flags: cisco 7000 board
EEPROM contents (hex):

Questions and Answers

Q. How do I know I have a product that is affected?

A. You can compare it to the list of Serial Numbers included in the field notice.

Q. Does this affect all 7500 chassis'?

A. Yes, although the chassis interface itself must be in the Serial Numbers affected list.

Q. What do I do if I have a product that is affected by this issue?

A. Raise an RMA to replace the affected chassis interface board.

Q. Do I have to return the old boards?

A. Yes, after receiving your new boards you will have 60 days to return the affected boards.

Q. What if I have a chassis interface with an affected serial number but I haven't seen any of the symptoms?

A. Cisco will proactively replace chassis interfaces that are within the affected Serial Numbers list.
