1. Prepare the Installation Site
■ Cabling - Only use the EPS cables supplied with the unit for external
power connections to switches. Only use the RPS cables supplied with
the 620 RPS/EPS for redundant 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 and RPS cables, EPS backup power 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 620 RPS/EPS can be mounted in these ways:
■ in a rack or cabinet
■ on a horizontal surface
Rack or Cabinet Mounting
The 620 RPS/EPS 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.
W A R N I N G For safe operation, please read the mounting precautions on
page 2-4 , before mounting the unit.

N o t e 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.
