Problem Description

A "bad lot" of 10Gbps laser modules used on the 15540-10GE-03B3xx assemblies may reduce the expected Mean Time Between Failure (MTBF) of the 15540-10GE-03B3xx Transponder assemblies.

Background

This issue was caused due to a bad lot.

Problem Symptoms

Due to a "bad lot" of 10Gbps laser modules used on the 15540-10GE-03B3xx Transponder assemblies, customers may experience higher than normal failures on assemblies that include the affected laser modules. The failures may occur during assembly installation or after a complete thermal cycling of the assembly where the unit is exposed to both temperature extremes. The primary concern with the laser modules is that the predicted MTBF may be negatively impacted resulting in a reduction of the expected service life of the assembly.

Workaround/Solution

Customers should screen all 15540-10GE-03B3xx Transponder assemblies to determine if they are affected by this issue. The multi-step screening process may require that the customer take affected 10G assemblies out of service to perform the screening. The screening of in-service assemblies should be scheduled during a maintenance window to ensure that production traffic is not affected. As well, any assemblies that have not yet been put in service should be screened to ensure they are not affected by this issue.

Once customers have completed the screening of their inventories, they should contact the Technical Assistance Center (TAC) to request an RMA to replace the affected material.

Due to limited availability of the wavelength specific laser modules used on the 15540-10GE-03B3xx assemblies customers should expect extended lead times for replacement materials. For some specific channels lead times are as long as eight weeks.

Step 1

To determine if a 15540 Transponder installed in a system requires physical screening, use the commands below in privileged EXEC mode to collect the Board Part Number for each 15540-10GE-03B3xx installed. Compare the Board Part Number to the list of potentially affected Part Number(s) noted in the Products Affected section. If the Board Part Number matches the affected Part Number(s) proceed to Step 2 for further screening instructions.

Field Screening

Step 2:

10Gbps Laser Module Serial Numbers
The 10Gbps laser module serial numbers of interest are found in the Serial Numbers section. All of the laser module serial numbers begin with the number 34 and end with a five digit serial number. See Figure 3 for an example of an actual serial number. To identify a serial number as one of interest, the last five digits of the number on the module label must match the last five digits of a number on the serial number list.

15540-10GE-xxxxxx Assembly Screening Instructions
Figure 1 is a photo of a 15540-10GE-xxxxx assembly. The arrow indicates where the 10Gbps laser module serial number is located in reference to the top of the assembly. Figure 2 is a photo showing the laser module serial number looking at the edge of the assembly. This is the number that is to be matched to the list of Affected Serial Numbers. The label is visible without any disassembly. Figure 3 shows the assembly serial number location on the bottom side of the assembly.

The 15540-10GE-xxxxxx assembly serial number should be noted if the laser module serial number is in the list of affected modules as this information is required when requesting an upgrade.
