Components .II

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. A power switch is provided to shut off all voltages, including the standby power. Not all ATX power supplies provide a power switch and therefore 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 removing 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 accommodate 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 permanent 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.
