Hard-Disk Drive for the Low-Profile Computer

The hard-disk drive assembly (consisting of the hard-disk drive and the hard-
disk drive bracket) is located inside the chassis at the left front of the computer
and is attached to the bottom of the chassis. One EIDE or SCSI 1-inch-high
hard-disk drive can be mounted on the hard-disk drive bracket.

Hard-Disk Drive for the Midsize Computer

The hard-disk drive bracket is located next to 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.

Hard-Disk Drive for the Mini Tower Computer

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.

Power-Supply Service Data

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.
WARNING: The voltage select switch, located on the back of the power
supply assembly, must be set to the correct operating voltage (115 V or
230 V) before you plug the power cable into an AC outlet.
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 connectors
must be connected to their corresponding power input connectors on the system
board or drives.
