Power Supply Replacement
In the event that one of the power supplies needs to be replaced, one power supply
can be removed without powering-down the system. Replacement power supply
units may be ordered directly from Supermicro.
Note that the power supply on top is PSU1 and the power supply on the bottom
is PSU2.

Changing the PSU1 Power Supply Module
1. With the system running, unplug the AC power cord from the PSU1 power
supply module.
2. Remove the thumbscrews around the PSU2 power cord anchor plate (free up
this plate without removing the PSU2 power cord).
3. Pull the PSU2 power cord out and to the side so that is doesn't interefere with
PSU1 being pulled from the system.
4. Press and hold the release tab at the top of the PSU1 power module.
5. Grasp the handle and pull the power supply out of its bay.
6. Push the replacement power supply module into the empty bay until it clicks
into the locked position.
7. Reposition the PSU2 power cord and secure the anchor with the thumb-
screws.
