Problem Description

Some ASR 9000 Series Aggregation Services Routers (ASR 9000) Enhanced Ethernet line cards and ASR 9001 chassis might not boot or might fail during operation with a memory error or a line card failure.

Background

Cisco has identified two issues with a specific DIMM supplier.

Issue #1: A batch of DIMM modules used on suspected hardware between June 2012 to August 2012. Based on field failure and Cisco's analysis, the current failure rate observed is low.

Issue #2: A batch of DIMM modules used on suspected hardware between November 2012 to December 2012. Based on field failure and Cisco's analysis, this issue causes the boards to fail early in the lifecycle.

Not all ASR 9000 hardware shipped in this period is affected. Use the Serial Number Validation Tool to verify suspect hardware.

The supplier has identified the manufacturing issue on the DIMM modules and implemented corrective actions.

Problem Symptom

The suspected ASR 9000 Enhanced Ethernet line cards and ASR 9001 chassis might not boot on power-up or might fail during operation with a memory error or hardware failure. These error messages might be seen for both issues.

Error message #1:

Error message #2:

Note: No syslog or error message will be seen when the hardware has power-up or boot-up issues.

Workaround/Solution

The suspected DIMM can be traced by the serial number of the ASR 9000 Enhanced Ethernet line card or the ASR 9001 chassis. The failure symptoms for each issue are the same, and the time to failure for each issue is different. Therefore, each issue is listed separately.

Use this table to check for Issue #1 and Issue #2 and take appropriate actions.

Note: The Serial Number Validation Tool is updated periodically. Not all serial numbers are affected. Check the serial number and the TAN to determine if hardware is good or affected.

The customer Service Level Agreement (SLA) does not apply for field notice replacement requests.

How To Identify Affected Products

The ASR 9001 chassis and ASR 9000 Enhanced Ethernet line card Product ID (PID), TAN, and serial number can be found in two ways:

1. Enter the show diag command to obtain the PID, TAN, and serial number. See the output sample for the suspected A9K-MOD80-TR line card.

   

2. Physically check the line card or chassis. Use the hardware pictures to identify the PID, board with serial number, and TAN.
