6-5 Power Supply
The 1011M-T2 has a single 260 watt power supply. This power supply has the
capability of operating at 100 - 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 re-
place the power supply unit. Replacement units can be ordered directly from the
manufacturer (PWS-0055).
Replacing the Power Supply
1. Accessing the inside of the system
To replace a power supply, you must fi rst remove the top chassis cover. To do so,
fi rst 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 recom-
mended 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.
