Power Supply

The SuperServer 8045C-3R has a redundant 1200 watt power supply consisting
of two power modules. (A third may be added for triple redundancy.) Each power
module has an auto-switching capability, which enables it to automatically sense
and operate at a 100V - 240V input voltage.

Power Supply Failure

Under normal operation, both of the modules are operating. If either of the two power
supply modules fail, the other module will take the full load and allow the system to
continue operation without interruption. The PWR Fail LED will illuminate and remain
on until the failed unit has been replaced. Replacement units can be ordered directly
from Supermicro. The hot-swap capability of the power supply modules allows you
to replace the failed module without powering down the system.

Removing/Replacing the Power Supply

You do not need to shut down the system to replace a power supply unit. The
redundant feature will keep the system up and running while you replace the failed
hot-swap unit. Replace with the same model (see Appendix D).
Removing the Power Supply
1. First unplug the power cord that corresponds to the failed power supply unit.
The power cords are oriented the same as the modules are (the left/top
power cord corresponds to the left/top power module).
2. Depress the locking tab on the power supply unit and pull the unit straight out
by the handle. See Figure 6-8.
