RPS Overview

An RPS (redundant power system) consisting of a C2RPS‐CHAS2 chassis and C2RPS‐PSM power supplies is a simple and economical solution to provide backup power for one or two SecureStack C2 Ethernet switch devices (one for each switch device). When a C2RPS‐PSM is connected to a switch device, it continuously monitors the internal power supply of the switch device. If a power interruption is detected, the C2RPS‐PSM is automatically triggered to provide power for the switch device, preventing an interruption in network traffic. The end result is a more reliable network infrastructure, protecting the network from a single source of failure from a network device power supply.

Depending on your system requirements, the C2RPS‐CHAS2 chassis can consist of the following components to provide redundant power for one or two switch devices:

•One C2RPS‐CHAS2 chassis

•One or two C2RPS‐PSMs (one per SecureStack switch device)

•One or two AC power cords (one per C2RPS‐PSM)

•One or two C2RPS‐PSM Cables (one per C2RPS‐PSM)

Note: The chassis is shipped without a PSM. The PSMs are ordered separately. Each

PSM is shipped with an interconnecting C2RPS-PSM Cable and an AC power cord.
