3.2.53.5-inch User-accessible Drive Bay

The system ships from the factory without the peripheral bay installed.

3.2.65.25-inch User-accessible Drive Bay

The system ships from the factory without the peripheral bay installed.

Note: Installation of hard disk drives in the 5.25-inch user-accessible bay is not recommended due to cooling and EMI constraints.

3.2.73.5-inch SCSI Hot-swap Drive Bays

Two 3.5-inch hot-swap capable bays support either 1.0- or 1.6-inch high SCA SCSI hard disk drives. These bays are accessible following removal of the lower bezel section. The wide LVDS SCSI hot-swap backplane provides industry standard 80-pin SCA-2 connectors for two drives. Two wide/fast-20 SCSI III SCA type hard disk drives can be installed in these bays. The wide LVDS SCSI hot-swap backplane is designed to accept drives that consume up to 28 watts of power and run at a maximum ambient temperature of 50° C (112° F).

Extruded aluminum drive carriers with integral heat sinks that accommodate 3.5-inch wide by either 1.0- or 1.6-inch high drives are required as part of the hot-swap implementation. The carrier is attached to the drive with four fasteners, and is retained in the chassis by a locking handle.

The LEDs below each drive display individual drive status. There are three LEDs for each drive: a power on (green) LED; an activity (green) LED; and a fault (yellow) LED. A fault LED on the front panel board also indicates a fault on these drives.

Note: Because all hard drives have different cooling, power and vibration characteristics, Intel will not validate hard drive types in the system chassis. Refer to the OCPRF100 MP Server System Validation Summary document for a list of these drives.
