External Device Connectors
The I/O panel provides connectors for a PS/2 compatible
mouse and a keyboard, connectors for VGA monitor, 2
serial port connectors, and a parallel port connector. It
also provides a narrow SCSI external connector.
Keyboard and Mouse
The keyboard/mouse controller is PS/2™-compatible.
Peripheral Devices
This subsection describes the SCSI-2 hard drive bays,
SCSI drive hot-swap backplane, and 5 1/4-inch
removable media drive bays.
SCSI-2 Hard Drive Bays
The right side of the system contains six bays for 3 1/2-
inch SCSI-2 hard drives and a hot-swap backplane (see
Figure 2-4). The backplane supports six drives. The
backplanes require an 80-pin single connector
attachment (SCA) connector on the drives you install.
A drive carrier is required as part of the hot swap
implementation. A 3 1/2-inch peripheral between 1.0
and 1.6 inches high can be accommodated in each
carrier. A drive is mounted in the carrier with four
fasteners, and the carrier is retained in the chassis by a
locking handle.
A fault light on the front panel board gives a general
indication that there has been a fault on a hot-swap
drive. Each drive has a set of three lights to indicate
the fault or other status: power-on (green LED), activity
(green LED), or fault (yellow LED).
