Products Affected Top Assembly Part Number
MPSM-16-T1E1 800-22339-08 (A0 - D0)

Problem Description

The MPSM-16-T1E1 metal EMI gasket may detach from the edge of the linecard during Online Insertion and Removal (OIR), causing an adjacent card to fail.

Only MPSM-16-T1E1 800-22339-08 are suspect.

Background

The MPSM-16-T1E1 metal EMI gasket failure was determined to be caused by a suspect gasket rework process at a downstream supplier. Due to the suspect rework process, the gasket may lose adhesion and come off when inserted or removed from the chassis. To date, less than 1% of the field population has experienced this failure.

All new versions of the product (800-22339-11 A0 and later) correct the problem by incorporating a faceplate assembly with a new EMI gasket which is applied by the original faceplate supplier.

Problem Symptoms

MPSM-16-T1E1 VERSION 800-22339-08 EMI gasket detaches.

Workaround/Solution

Workaround:
There is no workaround

Solution:
RMA the MPSM-16-T1E1 800-22339-08 (A0 to D0) to receive MPSM-16-T1E1 800-22339-11 A0 or later product using the standard RMA process.

Cisco recommends a fix-on-fail strategy for this problem.

As of approximately April 15, 2006 new products that were manufactured under Engineering Change Order (ECO) E085566 are guaranteed to be free of this problem.

Service Logistics has known-good inventory at this time. The standard RMA process and delivery times are in effect.
