We have a 2300 RPS with single 1150WAC power supply (C3K-PWR-1150WAC) which is connected to one 2921 Router. But it is not backing the rotuer.
Router 2921 running IOS
c2900-universalk9-mz.SPA.152-2.T1.bin
I am getting the following logs:
*** External Redundant Power Supply is present, but type is unknown or not supported.***
%ENVMON-1-POWER_WARNING: : RPS Online Insertion and Removal is not supported.
Do we required any configuration to be done on Router end.
Note: The RPS is backing 2960 Switch.

Hi Sankar,
A 2921 ISR G2 router requires both power supplies be populated in the RPS 2300. Also, there is no hotswap support in the RPS. For example, if you remove the RPS cable from the 2921 and plug it back in, you will need to reboot the router for it to recognize the RPS unit again.
Table 5-3 shows RPS 2300 backup capabilities when coupled with Cisco 2900 series ISRs.
No configuration is necessary on the router. You can use "show env rps" on any attached RPS device to check status.
