Power Supply
The SuperServer 5019C-MHN2 has a single 350W high-efficiency power supply. The power
supply module has an auto-switching capability, which enables them to automatically sense
and operate with a 100V-240V input voltage.
Power Supply Failure
If the power supply fails, the system will shut down and you will need to replace the unit.
Replacement units can be ordered directly from Supermicro (see contact information in the
Preface).
Removing the Power Supply
Begin by removing power from the system as described in Section 3.1.
1. First unplug the power cord from the power supply module.
2. Remove one screw by the fan and one screw by the AC power cord connector.
3. On the opposite side of the module, remove one screw at the center.
4. Lift the module up from the chassis.
Installing a New Power Supply
1. Replace the failed power module with another power supply module
(p/n PWS-350-1H).
2. Replace the screws by the fan and the AC power cord connector.
3. Replace the screws on the opposite side of the module.
4. Connect the AC power cord to the power supply module.
