6-5 Power Supply
The SuperServer 5012B-6/5012B-E has a single 250 watt power supply.
This power supply has an auto-switching capability, which enables it to
automatically sense and operate anywhere between 110v and 220v. A
power on/off switch is located at the back of the power supply. Turning
this power switch to the off position will remove both main and standby
power from the system.
Power Supply Failure
If the power supply unit fails, the system will shut down and you will need
to replace the power supply unit. Replacement units can be ordered di-
rectly from Supermicro (see contact infomation in Chapter 1).
Replacing the Power Supply
1. Accessing the inside of the SuperServer 5012B-6/5012B-E
To replace a power supply, you must first remove the top chassis cover.
To do so, first release the retention screws that secure the unit to the
rack. Grasp the two handles on either side and pull the unit straight out
until it locks (you will hear a "click"). Next, depress the two buttons on
the top of the chassis to release the top cover and push it away from
you. You can then lift the top cover from the chassis to gain full access
to the inside of the server.
2. Removing the power supply
First unplug the power cord from the system. To remove the failed
power unit, remove the two screws on the back of the power supply,
which secure it to the chassis. You can then lift the unit straight out of
the chassis. (The power cord should have already been removed.)
3. Installing a new power supply
Replace the failed unit with another unit of the same wattage. It is highly
recommended to replace it with the exact same power supply. Carefully
insert the new unit into position in the chassis and secure it with the two
screws at the rear of the unit. Before reconnecting the power cord,
make sure the power switch on the power supply is in the off position.
Then reconnect the power cord, replace the chassis top cover and push
the unit back into the rack. Finish by turning the power switch on the
power supply on, and then depress the power button on the front of the
system.
