Introduction
This chapter provides a functional overview of a Redundant Power System (RPS).
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
.
