Power Supply

The StorTrends 1100 has a single 300 watt power supply. This power supply has the
capability of operating at 100 or 240 input volts. Depress the main power button on the
front of the chassis and then unplug the AC power cord to completely remove power
from the system before removing the power supply.

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 American Megatrends
(PWS-0054 - see contact information in Chapter 1).

Replacing the Power Supply

1. Accessing the inside of the StorTrends 1100

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.
