Hot-swap Hard Drive Carrier
The hot-swap hard drive carrier accepts 15,000-RPM and slower Ultra320 SCSI technology SCA-
type hard drives. The peripheral bay supports Low Voltage Differential (LVD) SCSI disk drives
only. Single-Ended (SE) SCSI devices are not supported in the peripheral bay. SE drives are only
supported on the external SCSI connector. Refer to the Intel
and Operating System Validation List for details on tested devices. Contact your Intel
representative to obtain this list.
Hard drive carriers that accommodate 3.5-inch by 1.0-inch SCSI disk drives are required as part of
the hot-swap implementation. The disk drive is attached to the carrier with four fasteners, and is
retained in the chassis by a locking handle. Figure 6 shows a hard drive carrier that has been
removed from the peripheral bay. The drive is accessed by pressing the latch to release the drive
carrier door, then pulling out on the door.
The SCSI backplane board contains a dual-color LED for each hard drive. The LED can be seen at
the right edge of the carrier, as shown in the figure. The LED displays the drive status, as described
in Table 3.
