Install an External Redundant Power Supply

The RPS-550W and the RPS-950W redundant power supplies (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-002).

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.

  1. Carefully separate the four rubber pads that are provided
  2. Apply the pads to the underside of the RPS by placing a pad at each corner, ensuring that all corners are aligned. shows the locations for attaching the rubber mounting feet on the switch.

  1. 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.
