6-5 Power Supply
The SuperServer 6021i has a single 300 watt power supply. This power
supply has an auto-switching capability, which enables it to sense and
operate with either 110 or 220 volt inputs automatically. A power on/off
switch is located at the back of the power supply. Turning this power
switch to the off position will remove both main and standby power from
the system.
Power Supply Failure
If the power supply unit fails, the system will shut down and you will
need to replace the power supply unit. Replacement units can be
ordered directly from Supermicro. See contact information in the Preface.
Removing/Replacing the Power Supply
1. Removing the power supply:
First unplug the power cord from the system. remove the chassis cover
by pressing the two release buttons on the top of the chassis, near the
fron, and push the chassis top rearward about one inch. To remove the
failed power unit, unplug the power cord that connects to the power
supply. Then, remove all screws that connect the power supply to the
chassis (two at the rear, two at the side, and one on the bottom). The
power supply can then be lifted straight upward from the chassis.
2. Installing a new power supply:
Replace the failed unit with another unit of the same input voltage,
voltage outputs and Wattage. It is highly recommended to replace it with
exactly the same model power supply. Carefully insert the new unit into
position in the chassis and secure it with the five screws, as in the
paragraph above. Before reconnecting the power cord, make certain that
the power switch on the power supply is in the "off" position. Then
reconnect the power cord, replace the chassis top cover and reposition
the unit back into the rack. Finish by turning the power switch on the
power supply "on", and then depress the power button on the chassis
front panel.
