The FAStT100 supports up to 14 FAStT 1.5 Gbps SATA hard disk drives. These
drives are preinstalled in drive trays. The unit consisting of the drive and the drive
carrier assembly is called a drive CRU . The SATA drive CRU includes the drive tray,
the SATA drive, and the hard disk drive (HDD) interposer card. You install the drive
CRUs in the 14 drive bays on the front of the storage server. There are no
serviceable parts in a drive CRU. If it fails, it must be replaced in its entirety (drive,
interposer, bezel, and tray).
Attention:
1. Never hot-swap a drive CRU when its associated green Activity LED is flashing.
Hot-swap a drive CRU only when its associated amber Fault LED lights and is
not flashing or when the drive is inactive and its associated green Activity LED
lights and is not flashing.
2. The SATA drive and its HDD card are digitally signed together at the factory. Do
not swap drives and interposers between drive CRUs. Do not replace one SATA
drive with another SATA drive. These actions will result in a drive CRU that
cannot be recognized by the storage server RAID controller.
Note: If the hard disk drive you want to remove is not in a failed or bypass state,
always use the Storage Manager client program either to place the drive in a
failed state or to place the array that is associated with the drive (or drives)
in an offline state before you remove the drive from the enclosure.
