H122801 - BOWED BACKPLANE MAY CAUSE HARDFILE PROBLEMS TEXT: Testing and failure analysis has shown that some PC Server fixed disk problems may be caused by a bowed backplane. In cases where the drive is not fully seated in the backplane connector, it could appear Offline or DDD (drive defunct), or exhibit other drive-related failure symptoms. When diagnosing hardfile problems on PC Server systems, either solid or intermittent, examine the backplane card lengthwise for a bowed condition. If the card is bowed enough to potentially cause a poor drive connection, replace the backplane FRU. Note: The fixed disk assembly should plug into the backplane connector without excessive force. If the connectors are not properly aligned and the drive is forced, the backplane may be bent. This could result in other drives on the same backplane appearing Offline or DDD.
