3.9 Power Supply
The CSE-735D4-1K26B chassis includes a single 1200 Watt power supply. In the event that it
becomes necessary to replace the power supply, follow the instructions below. Replacement
units can be ordered directly from Supermicro.
Replacing the Power Supply
1. Remove power as described in Section 3.1 and remove the cover as described in
Section 3.2.
2. Remove the screws securing the power supply to the chassis, which are located on the
rear of the chassis. Set these screws aside for later use.
3. Disconnect the power supply from the motherboard connections.
4. Gently lift the power supply out of the chassis.
5. Replace the failed power supply with an identical power supply model.
6. Secure the new power supply using the screws previously set aside.
7. Plug the AC power cord back into the module and power-up the system.
Note:
BMC interface will detect power supply status when the system is powered on, but the
power supply will not support the standby mode for PMBus. This means when the system is
turned on about a minute after plugging in the AC, the BMC will not be able to access the
power supply information.
