Connection Requirements
This chapter describes the equipment required 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 a quasi-redundant configuration for all devices, fully
redundant configuration for the referenced Cisco routers and concentrator, and
redundant-with-reboot configurations for the referenced hubs and switches.
However, the redundant-with-reboot configuration is not recommended because a
power supply failure will cause an interruption while the hub or switch reboots.
For an explanation of power source configurations, refer to Chapter 1,
“Overview.”
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.
