6-5 Power Supply
The SuperWorkstation 7046A-HR+/7046A-HR+F has a redundant 1400 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.
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).
Removing the Power Supply
1. First unplug the power cord from the failed power supply unit.
2. Depress the locking tab on the power supply unit and pull the unit straight out
by the handle.
