Revision

500FR-7
The 500FR 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 both power supplies for power redundancy and cooling.
On frames with only one power supply, a 500PS-FM blank power supply module with cooling fan
must be
inserted into the second power supply space. The 500PS-FM contains a module cooling fan 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 2). 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.
