Replacing Power Supplies and Redundant Power Supplies
Installing and Removing a Redundant Power Supply Adapter
The redundant power supply (RPS) for the Cisco 2911, 2921, or 2951 router is an external
Cisco RPS 2300. To connect the RPS, the router must be fitted with an RPS adapter. A blank panel must
be removed before installing the RPS adapter. The external RPS attaches to a connector on the front of
the adapter. See Figure 5-32.
Note After connecting to the RPS2300, Cisco 2900 series routers require a reboot.
Tip For information specific to the RPS 2300, see the Cisco Redundant Power Supply System Hardware
Installation Guide at:

hig.html
Depending upon RPS configuration, more than one router can be backed up.
Caution Failure to follow the RPS Installation or Removal procedures can cause damage to the router, RPS
adapter, RPS cable, or RPS.
