The RPS-150W-XT redundant power supply (RPS) can be installed on a flat surface, or in a
19-inch rack using the included two-post rack mount kit (XN-2P-RMKIT-003).
Install the RPS on a Flat
Surface
Four self-adhesive rubber pads are provided for installing flat surfaces, like a
table. The pads keep the RPS from scratching the supporting surface and help ensure
adequate airflow around the RPS.
To install an RPS on a table - or any firm, flat surface - follow these steps.
Carefully separate the four
rubber pads that are provided
Apply the pads to the underside
of the RPS by placing a pad at each corner, ensuring that all corners are
aligned. Table Mount: Attaching Rubber
Feet shows the locations for attaching the rubber mounting feet
on the switch.

Install the RPS in a Rack
The RPS can be installed in a four-post rack, using just the two front posts or two back posts,
or a two-post rack. This procedure uses a two-post mounting kit, which accommodates
rack posts 3 inches or 6 inches wide. Rack ears can support both flush- and
mid-mounting. To install the RPS you need:
Two rack mount brackets and mounting screws (rack mount kit) shipped with the
RPS.
Four customer-supplied screws to attach the RPS to a standard 19-inch rack.
To install the RPS in a rack:
Attach a mounting bracket to each
side of the RPS, using the screws provided. Align each mounting bracket so that
the flange (ear) faces the front of the RPS to flush-mount, or faces the rear of
the RPS to mid-mount.

With the mounting brackets attached, position the RPS between the vertical rack
rails of the 19-inch rack.
Fasten the RPS securely to the
rack rails using four customer-supplied rack screws.

Dual Rack Mount the RPS
Two RPS-150W-XT models can be dual rack mounted in a two-post rack. To install:
Attach two short brackets to the outer sides of the two devices using four M3
screws per bracket.
Attach two additional short brackets to the inner side of the right device using
two M3 screws per bracket.
Attach the final long bracket to the inner side of the left device using four M3
screws.
Slip the short connecting brackets on the device on the right into both ends of
the long connecting bracket on the device on the left.
Attach the connecting brackets to each other using the four remaining chassis
screws. The devices can be installed in the rack as a single unit.
Dual Rack Mount: Connecting the Devices
Attach the switches to the rack using rack-mounting hardware (not provided).

Connect the RPS Cable and the AC Power Cord
Important
Connections must
be made in a specific order when attaching an RPS to a powered system.
To connect the RPS:
Connect the RPS cable between the switch and the RPS before connecting
the AC power cord. The RPS cable is connected from the Redundant Power Output on
the rear panel of the RPS to the Redundant Power Input on rear panel of the
switch.
Connect the AC power cord to the AC input power connector on the RPS, then plug
the AC power cord into the main AC power outlet.
RPS cable and AC Power Cord Connection
The AC power LED on the rear of the RPS turns green to indicate a successful
connection and that the RPS is operating properly.
