Connecting Routers to Backup Power

The Cisco 3845 router accommodates two hot-swappable power supplies in bays at the front of the router. A single power supply meets router requirements. The second power supply provides redundancy, load sharing, and increased router availability. Either power supply can be removed without affecting router operation. Any combination of two power supplies is permitted.

For instructions for installing a second power supply in a Cisco 3845 router, see the “Installing and Upgrading Internal Components in Cisco 3800 Series Routers” section.

The Cisco 3825 router has one internal power supply and provides a connector to an optional

Cisco Redundant Power System (RPS) external backup source. Figure 20 and Figure 21 illustrate this connection. Use a flat-blade screwdriver to pry off the door over the RPS connector before connecting the cable. See the Cisco RPS-675 Hardware Installation Guide for complete RPS power connection instructions.

Caution Before connecting the RPS to the router, make sure that either the RPS is in standby mode or the RPS AC power is disconnected. Connecting the RPS to AC power automatically places the RPS in active mode.
