Problem Description

Connectors falling off the backplane and ground clips dislodging from the edges of line cards.

Background

Connectors have separated from the backplane while removing a card on two separate USB card cages for the high density solution that has been deployed at a customer site.

Problem Symptoms

1. Connectors falling off the backplane

Last fall, September/October 2006, there was an issue with connectors falling off of the USB chassis. Failure analysis pinpointed the root cause of this problem to be an improper test procedure at the vendor that placed undue stress on the connectors as cards were inserted and removed to test the chassis. The physical strength of the connector and the mounting and soldering processes were evaluated to be sufficient for insertion and removal associated with installation and customer use.

The test procedure was modified and all suspect inventories were purged from Foxconn Texas and Ingram inventory.

A chassis was recently returned via a TAC case RMA for connectors falling off the backplane. Examination of the date code on the chassis indicated that it was built prior to the manufacturing remediation to eliminate the connector problem.

No chassis with manufacture date codes prior to October 2006 should be installed. They should be exchanged for current stock. The manufacture date code can be derived by looking at the backplane S/N. The backplane assembly S/N can be viewed by removing the back cover of the chassis and the S/N sticker is located at the bottom left side of the backplane board.

There should be no such stock in the field, but it may happen that a customer or channel partner may have a unit shipped before the problem was addressed.

Please view the list with following backplane S/N range - if the S/N is found, then the entire chassis should be replaced.

2. Ground clips dislodging from the edges of line cards

Some linecards manufactured by Sypixx in 2005 had ground clips attached to the linecard edges with the intention to ensure that the cards were properly grounded for EMI. Subsequent EMI testing demonstrated that the clips were unnecessary and the clips were eliminated from the product and are no longer part of current production.

The clips would only become apparent if a linecard that has the clips is removed from the chassis. When such a linecard is removed, the clips may remain in the card guides, may remain on the linecard edge, or may just fall loose.

In any event, it is not necessary to replace them. They can be removed from the linecard or the card guides and may be discarded. It is not necessary to remove the clips from working chassis.

Workaround/Solution

Any chassis being installed should be checked to ensure that it is not from the group of datecodes prior to the remediation.

No chassis with manufacture date codes prior to October 2006 should be installed. They should be exchanged for current stock through manufacturing.
