Problem Description

In some conditions, the SFP cages can lock in the SFP module manufactured by OCP. The interference can occur between the SFP cage gasket and the SFP body (only OCP is affected) when inserted in the position 6 or 12 of the cards.

This has only happened in the lab, and not in the field or customers sites.

Background

The engineering team has found that the deformed finger within the SFP card cage can engage the SFP package on the recessed side feature and will lock the pluggable inside that cage. This has not happened at any customers sites, only in the lab.

Problem Symptoms

In case of the failure, the SFP inserted in position 6 or 12 cannot be pulled out of the MRC card.

Workaround/Solution

The workaround/solution available for this card is to have it replaced through the normal Cisco RMA process.
