Problem Description

Units with Release 9.6.0 software shipped prior to December 31, 2012 receive a a BACKUPMEMP alarm within 2 to 3 days after a reset. A genuine memory corruption also results in BACKUPMEMP alarm. This particular issue does not impact service, but the workaround in this document should be implemented to correct the situation.

Background

TNC/TSC/TNCE/TSCE cards with Release 9.6.0 software shipped prior to December 31, 2012 contain a file with an additional empty line (CR/LF). This leads to a CRC audit process failure for the file when the regular CRC audit runs on the controller card. This failure raises the BACKUPMEMP alarm on the controller card. Since the audit process runs periodically, this alarm is seen within 2 to 3 days and not instantaneously.

Problem Symptom

The BKUPMEMP alarm is raised on certain TNC/TSC/TNCE/TSCE cards. The impacted cards are captured in the "How To Identify Affected Products" section.

Workaround/Solution

In order to resolve the issue, load the Release 9.6.0 or later software from CCO to both partitions of the impacted controller cards. For a node which has a primary shelf or subtended shelf with impacted controllers, the steps to resolve this issue are as follows:

Note: If you use ETSI (SDH) mode with a primary shelf controller of 15454-M-TNCE-K9, 15454-M-TNCE-K9=, 15454-M-TSCE-K9, or 15454-M-TSCE-K9=, then use either TL1 or use CTC of a future software release (9.6.0.3 or later) for the software download.

1. If this is a provisioned node, back up the database.
2. Download the software. Each controller has two software partitions, Active and Protect (for example, P1 and P2). The software is downloaded to the Protect partition (P2) of the Active and Standby Controller of theh primary shelf and subtended shelves.
3. Perform an Activate to make the new load just downloaded the working load. P2 is now the Active Partition.
4. Download the software again to replace the load in the current Protect partition (P1). The correct software is now in both partitions, P1 and P2, in the controller.
5. If USB flash memory is present in M2/M6, perform an Activate to copy the new software to flash memory.

How To Identify Affected Products

TNC/TSC/TNCE/TSCE cards listed in the "Products Affected" section that have shipped with Release 9.6.0 software prior to December 31, 2012 experience BKUPMEMP alarm declaration.

Customers should check their TNC/TSC/TNCE/TSCE card serial number against the serial number validation tool provided below. The serial number validation tool identifies affected hardware. Customers who identify their hardware as affected should follow the workaround procedure described in the "Workaround/Solution" section to avoid this issue.
