Problem Description

If an OSM-2+4GE-WAN+ receives enough mechanical shock during transport or during the install process, there is a risk of failure and network stoppage after initial installation.

Background

We experienced a larger than normal Dead On Arrival (DOA) Rate on OSM-2+4GE-WAN+ boards during the first 3 months of shipments. All boards were verified to be functional upon shipment. The failures occur upon bring up at the customer site, and have only been seen with spare shipments. Once the board is up and running, we have not observed any failures. The failure mode seen in spare shipment includes traffic not passing through Port 1 and 2, sometimes even Port 3. This failure is due to damage to two components along the top edge of the board.

Problem Symptoms

Upon initial installation, the OSM-2+4GE-WAN+ is not configurable or is unable to pass traffic through Port 1 or Port 2. Ports 3 and 4 are also at risk of the same failure, but to a lesser degree due to the fact that they not as susceptible to mechanical shock.

Workaround/Solution

Immediate Solution:

If it has been determined that an OSM-2+4GE-WAN+ is experiencing a failure such as the one outlined in the Problem Symptom section above, and the product falls within the serial number range listed in the How To Identify Hardware Levels section below, a DOA Return Material Authorization (RMA) must be placed in order for the part to be replaced.

How To Identify Hardware Levels

The affected versions of this card can be identified by the Serial Numbers and by the Cisco Top Assembly Number (TAN). Those Part numbers that end with a -03 and -04 are impacted by this Field Notice.
