Peripherals

3.5-inch Diskette Drive

The 3.5-inch diskette drive in the 3.5-inch peripheral bay supports 720 KB, and 1.44 MB media.
The drive is accessible from the front of the system.

3.5-inch Hard Drive Bays

The system was designed to allow the user to install a Redundant Array of Independent Disks
(RAID). A hot-swap-capable backplane accommodates six RAID 3.5-inch-wide (1-inch high) hard
disk drives, which are accessed from the front of the system.
A drive carrier is required as part of the hot-swap implementation. The drives are mounted in the
carrier with four fasteners and the carrier snaps into the chassis. The 10 K rpm hard disk drives
with power exceeding 15 watts require heatsinks and system fans for extra cooling. These parts are
available in an optional kit.
For information on how and when to install heatsinks, see "Installing Heatsinks on High-
Power Drives" on page 76.
For information on how and when to install extra fans, see "Installing Fans for High-Power
Drives" on page 100.
A metal EMI shield and door cover the drive bays. A hot-docking bay is provided for drives that
are 3.5 inches wide and 1 inch high. Drives can consume up to 22 watts of power and must be
specified to run at a maximum ambient temperature of 55 C.

5.25-inch Removable Media Device Bays

The chassis has three 5.25-inch half-height bays that are accessible from the front of the system.
These bays are intended to provide space for tape backup or other removable devices.
You can convert the 5.25-inch bays to a single full-height bay. You should not use these bays for
hard disk drives because of inadequate cooling, and because they generate EMI which increases the
possibility of electrostatic discharge (ESD).
