Section 2 — Installation
Switcher Frame Power Supply Installation
The Primary Power Supply must be mounted immediately below the
switcher frame in the rack. If you are installing an optional Redundant
Power Supply, it must be located immediately below the Primary Power
Supply. Verify that you have allowed enough rack space (7 rack units per
Supply) before proceeding.
WARNING
To reduce the risk of electric shock, do not perform any servicing other than
that contained in the operating instructions unless you are qualified to do so.
To install the Switcher Frame Power Supply in the equipment rack, refer to
Figure 2-7 and proceed as follows:
1. Ensure that the Primary and Redundant Power Supplies are
disconnected from all power sources.
2. Locate the installation kit containing the power supply assembly slide
mounts and hardware. The installation kit consists of the following:
a. Slide Mounts
b. Mounting Hardware
3. Measure the location of the slide sections mounted on the power
supply chassis to determine the height at which the stationary sections
of the slides are to be mounted in the rack.
NOTE:
The Primary Power Supply will be attached to the bottom of the switcher
frame by eight captive screws. It must be installed so that it is touching the bottom
of the frame.
4. Verify that the screws holding the chassis sections of the slides to the
power supply chassis are securely tightened.
5. Mount the rack sections of the slides to the front and back of the rack
and secure them in place with the appropriate screws as illustrated in
Figure 2-7. The mounting ears at the front of the slides should mount to
the inside of the rack rail. On threaded rails, run short pan head screws
from the inside. On unthreaded rails, run flat head screws (with nuts)
from the outside. This results in the power supply being flush with the
frame; plus allowing for the proper mating of the electrical connectors
in back. It may be necessary to adjust the length of the rear brackets,
depending upon the depth of the rack assembly.
