•
Phillips (+) screwdriver, number 1 (not provided)

Mount the RPS
Installing the RPS requires one person to lift the switch and a second person to secure it to the rack. Mount an RPS on
two posts of a 19-in. rack or cabinet by using the mounting brackets provided with the switch. You can also mount an
RPS on four posts of a 19-in. rack or cabinet by using the separately orderable four-post rack-mount kit. There is no
traditional front and back on an RPS. You can position either the switch connector side or the power supply side of the
RPS at the front of the rack.
