Intel® Entry Server Chassis SC5250-E System Peripheral Bays

Revision 1.02

Intel order number C32881-001

5.2 5.25” Peripheral Drive Bays

The SC5250-E chassis supports two half-height or one full-height 5.25-inch removable media

peripheral device, such as a magnetic/optical disk, CD-ROM, or tape drive. These peripherals

can be up to 9 inches (228.6mm) deep. As a guideline, the maximum recommended power per

device is 18W. Thermal performance of specific devices must be verified to ensure compliance

to the manufacturer’s specifications.

The 5.25-inch peripherals are removable from the front of the chassis after taking off the access

cover and removing the front bezel. EMI shield panels are installed and should be retained in

unused 5.25-inch bays to ensure proper cooling and EMI conformance.

Note: Caution when approaching the maximum level of integration for the 5.25-inch drive bays.

Power consumption of the devices integrated needs to be carefully considered to ensure that

the power supply maximum power levels are not exceeded. Typical configurations can supply

enough power for a floppy drive, a tape drive, a CD-ROM, and four fixed hard drives.

5.3 Hard Drive Bay

The server chassis SC5250-E comes with a removable hard drive bay that can accept up to six

cabled 3.5” x 1” hard drives. Power requirements for each individual hard drive may limit the

maximum number of drives that can be integrated to a server chassis SC5250-E. This bay has

a 92mm (6.2 inches) x 25mm fan mounted to the front to provide airflow to the hard drives

mounted in it. The drive bay secures with two screws in the front of it and two screws on the

side.

Note: The hard drive bay must be slid forward or removed to install the baseboard.

The server chassis SC5250-E server chassis is capable of accepting a single SCSI hot swap

backplane hard drive enclosure in place of the fixed drive bay. This is the same enclosure that

is used in the Intel Server Chassis SC5100 and SC5200. The backplane is an LVD/SE SCSI

design, which provides support for SCSI devices, using Low Voltage Differential Signaling, as

well as support for older SE SCSI devices (Ultra 160 and older). The backplane has a connector

to accommodate a SAF-TE controller on an add-in card. The backplane supports five 1-inch

hot-swap SCA-2 drives when mounted in the docking drive carrier.

5.4 SCSI Multi-Mode Termination

The multi-mode terminators provide SCSI-4 compliant termination for the backplane. These

terminators provide termination in both SE modes and LVD mode. Installing a single SE drive

forces all installed drives to run in the SE termination mode on the SCSI bus.
