2.0 Installing The Power Supply

NOTE: The common equipment cabinet employs an electronic switching power supply. During operation, power
supplies of this type generate an audible sound from their switching regulators. This sound is normal and
is not an indication that the power supply is operating improperly.
Install the power supply assembly in the common equipment cabinet per the following discussion and illustration.
1. Be sure to ground the common equipment cabinet per the instructions in the previous paragraph before
installing the power supply assembly.
2. Remove the power supply assembly from the carton. Be sure to save the small bag containing the mounting
hardware.
3. Slide the power supply assembly into the opening at the top right side of the common equipment main cabinet
until the assembly's front panel contacts the side of the cabinet.
4. Locate the power cable routed from the backplane and connect it to the power supply's connector.
5. Remove the #6 thread-forming screws from the hardware bag and secure the assembly to the cabinet.
6. The supplied power supply assembly accessories include a ferrite collar. Snap this collar around the AC
power cord to provide protection against radio frequency interference.
