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 1-inch-high EIDE hard-disk

drive can be mounted on the hard-disk drive bracket.

NOTE: Throughout this manual, references to component locations assume

the chassis orientation illustrated in Figure 1-7.

The computer has a 145-W system power supply that 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.
