The hard-disk drive bracket is located beneath the externally accessible drive

bays at the front of the computer. The hard-disk drive bracket can contain

either one or two 1-inch-high EIDE or SCSI hard-disk drives, or one 1-inch-high

EIDE or SCSI hard-disk drive and one 1.6-inch-high EIDE or SCSI hard-disk

drive.

One 1-inch-high EIDE hard-disk drive can be mounted to the top of the

expansion-card cage.

The low-profile computers have a 145-W system power supply, the midsize

computers have a 200-W system power supply, and the mini tower computers

have a 230-W power supply. All system power supplies can operate from an

AC power source of 115 VAC at 50 to 60 Hz or 230 VAC at 50 to 60 Hz.

The system power supply provides the DC operating voltages and currents

listed in Table 1-4.

NOTE: The power supply produces DC voltages only under its loaded condi-

tion. Therefore, when you measure these voltages, the DC power input

connectors must be connected to their corresponding power input connectors

on the system board or drives.

The combined load on the +5-VDC and +3.3-VDC outputs should not exceed 105 W on

the low-profile computers or 140 W on the midsize/mini tower computers.

Withstands surges of up to 11.0 A to support disk start-up operations.
