power connections to switches.
■ Installation Location - Before installing the unit, plan its location and
orientation relative to other devices and equipment:
• In both the front and back of the unit, leave at least 7.6 cm (3 inches)
of space for the EPS cables, and the power cord.
• On the sides of the unit, leave at least 7.6 cm (3 inches) for cooling.
2. Mount the Unit
The Power Supply Shelf can be mounted in these ways:
■ in a rack or cabinet
■ on a horizontal surface
Rack or Cabinet Mounting
The Power Supply Shelf is designed to be mounted in any EIA-standard 19-
inch telco rack or communication equipment cabinet. The mounting brackets
have multiple mounting holes and can be rotated allowing for a wide variety
of mounting options.
WARNING For safe operation, please read the installation precautions on
page 2-3, before mounting the unit.
Equipment
Cabinet
Note
The 12-24 screws supplied with the unit are the correct threading for standard
EIA/TIA open 19-inch racks. If you are installing the unit in an equipment
cabinet such as a server cabinet, use the clips and screws that came with the
cabinet in place of the 12-24 screws that are supplied with the unit.
1. Use a #1 Phillips (cross-head) screwdriver and attach the mounting
brackets to the unit with the included 8-mm M4 screws. The screws must
be tightened sufficiently to provide proper support for the unit in the rack.
