6-5 Power Supply
The SuperServer 6011L has a single 250 watt power supply. This power
supply has an auto-switching capability, which enables it to automatically
sense and operate with either 110 or 220 volt inputs. 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 directly from Supermicro. See contact information in the Preface.
Replacing the Power Supply
1. Accessing the inside of the SuperServer 6011L:
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: (See Figure 6-6)
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 exactly the same model 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 reposition 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.
