6-5 Power Supply
The AS1040C-T/1040C-8 has a single 1000 watt power supply, which is auto-switch-
ing capable. 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 back of the chassis. To remove the failed power unit, push the colored release
tab to the right and then pull the unit straight out of the chassis. It will automatically
detach itself 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 the opening at the front of the chassis and push it completely in to seat it on the
power distribution board. Reconnect the power cord and reposition the unit back
into the rack. Finish by depressing the power button on the chassis front control
panel to power on the system.
