6-5 Power Supply
The SuperServer 5025M-UR has a 700 watt redundant power supply consisting of
two power modules. Each power supply module has an auto-switching capability,
which enables it to automatically sense and operate at a 100V - 240V input volt-
age.
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 power supply units have a hot-swap capability, meaning you
can replace the failed unit 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
backup power supply module will keep the system up and running while you replace
the failed hot-swap unit. Replace with the same model (see part number in the
Appendix), which can be ordered directly from Supermicro.
1. Removing the power supply
First unplug the power cord from the failed power supply module. Then depress
the locking tab on the power supply module and use the handle to pull it straight
out with the rounded handle.
2. Installing a new power supply
Replace the failed hot-swap unit with another identical power supply unit. Simply
push the new power supply unit into the power bay until you hear a click. Secure
the locking tab on the unit and fi nish by plugging the AC power cord back into the
unit.
