6-5 Power Supply
The SuperServer 4021M-32R has a redundant 800 watt power supply consisting
of two power modules. Each power supply module has an auto-switching capabil-
ity, which enables it to automatically sense and operate at a 100V - 240V input
voltage.
Power Supply Failure
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. Re-
placement units can be ordered directly from Supermicro (see contact information
in the Preface). 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).
1. Removing the power supply
First unplug the power cord from the failed power supply unit. Then depress the
locking tab on the power supply unit and pull the unit straight out by the handle.
2. Installing a new power supply
Replace the failed module with another power supply module (must be the exact
same - refer to Appendix D for part number). Simply push the new power supply
unit into the power bay until you hear a click. Finish by plugging the AC power cord
back into the unit.
