Replacing the Power Supplies
The CSE-F418BC3 chassis includes four redundant 2200W power supplies. These power
supplies are auto-switching capable. This enables the power supplies to automatically sense
and operate at a 100v to 240v input voltage. An amber light will be illuminated on the power
supply when the power is off. An illuminated green light indicates that the power supply is
operating.
Power Supply Replacement
In the event that any of the power supply units need to be replaced, it can be removed without
powering down the system. Replacement units can be ordered directly from Supermicro.
Changing the Power Supply
1. Disconnect the AC power cord on the back of the failed power supply unit.
2. Press the release tab on the back of the power supply and pull it out using the handle
provided.
3. Insert the replacement power supply module into the power bay and push it in until it
clicks into the locked position.
4. Plug the AC power cord back into the power supply module and the new module will
automatically power up.
