Introduction
This chapter provides a functional overview of the Redundant Power System (RPS),
which includes the following:
RPS
Overview
The RPS provides a simple and economical solution for providing a backup power source
for up to eight SecureStack Ethernet switch devices. When a PSM is connected to a switch
device, the PSM continuously monitors the internal power supply of the switch device. If
a power interruption is detected, the 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 RPS can consist of the following
components to support up to eight switch devices:
•
One C2RPS‐CHAS8 chassis
•
Up to eight C2RPS‐PSM
s
•
Up to eight AC power cords (one per C2RPS‐PSM)
•
Up to eight C2RPS‐PSM Cables (one per C2RPS‐PSM)

Note: The chassis is shipped with one PSM. Additional PSMs are ordered separately.
Each PSM is shipped with an interconnecting C2RPS-PSM Cable and an AC power cord
.
