II. System Components

Power Supply

This server has a standard power supply with specifications to meet this

server's motherboard requirements. A clearly marked label gives detailed

specifications of the power supply. It is normal practice to remove the power

cord before opening the side panel. With the power cord removed, you can

ensure there are no voltages which can cause shorts while installing or re-

moving internal components.

CAUTION:

Before turning on your server for the first time, set the power

supply's voltage. Some products may have auto voltage switching to ac-

commodate 220V-240V or 110-120V but this power supply must be set

manually. The factory default should be on 230V to accommodate the higher

voltage but it is safer to visually inspect the switch yourself in case it is not.

IMPORTANT:

For countries using 110V-120V, you must slide the switch

to 115V or else power up is not possible (but no damage will occur).

Power Supply On and OFF

Normal powering ON and powering OFF of the ATX power supply is done

using the momentary ATX power switch located on the front panel which is

connected to the motherboard, unlike AT power supplies which uses a per-

manent switch on the power supply or chassis. The power supply's main

power switch must be turned on before the ATX power switch on the front

panel will work.

Power Supply Mounting

Mounting and unmounting the power supply must be done from the inside

as shown below. Four screws are used to secure the power supply to the

chassis back side.
