Installing the Power Supplies
Preparation
If there are blank cover plates over bays where power supplies are to be installed, loosen the screws,
located at the top of each cover plate. Remove the cover plates and set the plates and screws aside.
Note.
Be sure to replace cover plates over any unused power supply bays.
Installation Steps
Install the power supplies in the power shelf by following the steps below.
1
First, be sure that you do not install the power supply upside down. When orienting the power supply,
note that the on/off switch and power cord socket are located at the
bottom
of the power supply and the fan
is located at the
top
of the power supply.
2
With one hand, grasp the handle at the front of the power supply. Place your other hand under the
power supply casing to support its weight.
3
Carefully insert the rear of the casing into the power supply bay and slide the power supply back until
its connector meets the chassis backplane connector.
4
Continue sliding the power supply back until the front panel meets the front of the chassis.
Do not
force the power supply into the bay. Otherwise you can damage the connectors.
