PC Server 320 / 500 - Hot swap fixed disks fail to power up
Applicable to: World-Wide
Symptom
During system POST (Power-On System Test), one or more fixed disk drives do not power up. The green LED's on the drive trays (locking handle) are NOT On. This problem may be intermittent. Powering off, then back on, usually brings all the fixed disks back online. Once all drives are ready, system operation is normal.
Problem Isolation Aids
None
Fix
The fixed-disk drive backplane has a micro processor which controls the power-on functions of the hot swap fixed disks. This micro processor controls power to all of the drives, therefore, a solid or intermittent failure in the backplane can result in removal of power from all drives in that bay, forcing them offline. If these symptoms are being experienced, the backplane should be considered suspect. The Server 500 (8641, all models) and Server 320 RAID Array systems both use a similar, but not identical backplane.
