Do not run the frame for extended periods of time with one of the power
supplies removed or with the door open. Proper cooling of the frame requires
both power supplies to be inserted into the frame, or one power supply and a
power supply fan module.
The 7800FR power supplies are hot swappable and can be easily replaced from the front without
interrupting the signal integrity of the frame. Each power supply is capable of supplying full power to the
frame by itself, however we recommend running with both supplies powered for power redundancy. On
frames with only one power supply, a blank power supply fan module with cooling fan (properly rated for
the wattage of the power supply) must be inserted into the second power supply space. The blank power
supply fan module contains a module cooling fan sufficient to cool the maximum power dissipation of the
frame and baffles to maintain proper airflow within the frame.
The power supply is secured into the frame by a machine screw through the rear panel (as shown in
Figure 5-1). This screw must be removed before the power supply can be extracted from the front.
To reduce risk of electric shock you must replace the mounting screw after
replacing the power supply.
