Connecting to External Devices
This section describes how to connect the Cisco RPS to external devices. The Cisco RPS
includes two fully redundant AC input power modules and four DC output power modules
for connection to external devices. The Cisco RPS supports quasi-redundant, fully
redundant, and redundant-with-reboot configurations. For an explanation of power source
configurations, refer to Chapter 1, “Overview of the Cisco RPS.”
Caution
The Cisco RPS AC input power modules are power-factor-corrected to comply
with certain International Electrotechnical Commission (IEC) standards. Do not connect
the Cisco RPS to an uninterruptible power supply (UPS) that has not been tested and
designed for power-factor-corrected power systems. Do not connect the Cisco RPS to a
ferro-resonant transformer. If you do either of these things, you could damage the
Cisco RPS.
Tools and Equipment Required
You may need the following tools and equipment:
•
Y-cable—Needed for fully redundant power configurations.
•
Upgrade kit—Needed for routers that originally came with AC or DC power supplies
(Cisco 2500, 2600, 3600, 4000 series routers or the Cisco MC3810 multiservice
concentrator).
