Field Notice 19817: 15454-OC12-4 Connector Seating Issue


July 2, 2002



Products Affected

  • Cisco ONS 15454-OC12-4

  • Cisco ONS 15454-OC12-4=

Problem Description

Cisco ONS 15454-OC12-4 optical boards have been found to exhibit the following mechanical connector issues.

  1. Insufficient Engagement caused by certain duplex clip interference.

  2. Receptacle retainer clip deformation when subjected to high temperatures with the connector not fully engaged.

Background

  1. With certain duplex clips, interference between the connector housing and the duplex clip prevents the connector from fully engaging, causing the connector to fail to fully seat and lock into place.

  2. If subjected to high temperature (50° C) with the connector not fully engaged, the retaining fingers within the connector receptacle can become deformed, defeating proper operation.

Problem Symptoms

  1. The duplex clip may contact the connector housing before the connector is fully seated, preventing the connector from latching in to place.

  2. If as a result of being subjected to high temperature (50° C) with the connector not fully engaged, the retaining fingers within the connector receptacle become deformed, the male connector will no longer snap in to place.

Workaround/Solution

  1. Ensure that the male connector is fully seated in the receptacle and has snapped into place prior to operation. If the connector fails to fully engage due to interference between the duplex clip and the connector housing, remove the duplex clip and reinsert the connectors making sure that they are fully seated.

  2. If the receptacle has been subjected to high temperature with the connector not fully engaged and the retaining clips no longer retain a properly inserted male connector, the board will need to be replaced. Contact the Technical Assistance Center as outlined below to obtain a replacement.

Please ensure strict adherence to the product documentation and any related release notes.
