Power Supply

The SuperServer 7048R-C1RT/7048R-C1R has a redundant, hot-plug 920 watt
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 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. Replacement
units can be ordered directly from Supermicro (see contact information in the Pref-
ace). The hot-swap capability of the power supply modules allows you to replace
the failed module without powering down the system.
Replacing the Power Supply
You do not need to shut down the system to replace a power supply module. The
redundant feature will keep the system up and running while you replace the failed
hot-swap unit. Replace with the exact same model (see Appendix B).
1. Unplug the AC power cord from the failed power supply module.
2. Remove the chassis left-top cover as described in Section 6-3.
3. Remove the screws that secure the power module to the chassis then pull it
completely out.
4. Replace the failed unit with another unit of the exact same part number (see
Appendix).
5. Gently but firmly push the new unit all the way into the open bay.
6. Secure it to the chassis using the screws you previously removed.
7. Finish by replacing the chassis left/top cover and then plugging the AC power
cord back into the new module you just added.
