OCPRF100 MP Server System Technical Product Specification
Revision 1.0
26
3.2.5 3.5-inch User-accessible Drive Bay
The system ships from the factory without the peripheral bay installed.
3.2.6 5.25-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.
3.2.7 3.5-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 car-
rier 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 Sys-
tem Validation Summary document for a list of these drives.
