6-5 Power Supply
The AS1020S-8 has a single 500 watt power supply, which is auto-switching ca-
pable. This enables it to automatically sense and operate at a 100v to 240v input
voltage. An amber light will be illuminated on the power supply when the power is
off. An illuminated green light indicates that the power supply is operating.
Power Supply Failure
If the power supply unit fails, the system will shut down and you will need to re-
place the unit. Replacement units can be ordered directly from the manufacturer.
As there is only one power supply unit in the system, power must be completely
removed from the server before removing and replacing the power supply unit for
whatever reason.
Removing/Replacing the Power Supply
1. Removing the power supply
First turn the power switch on the control panel off, then 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 front) and push the chassis top rearward about
one inch. To remove the failed power unit, push the beige colored release tab to
the right and then carefully lift the unit up about 1/2 inch only. If you lift too high,
you may damage the power distribution board that the other end of the unit is
connected to. Then, pull the power unit straight back to unplug it from the power
distribution board. See Figure 6-6.
2. Installing a new power supply
Replace the failed unit with another unit of the same input voltage, output voltage
and wattage (manufacturer part number PWS-0048). It is highly recommended to
replace it with exactly the same model power supply. Carefully insert the new unit
into position to plug it into the power distribution board, making sure you are not
holding it at too great an angle, which may damage the power distribution board.
Push it completely into the power distribution board and seat it in the chassis. When
correctly installed it should be laying fl at - make sure the end of the power supply
is not sitting on the stop in the chassis. Reconnect the power cord, replace the
chassis top cover and reposition the unit back into the rack. Finish by depressing
the power button on the chassis front control panel.
