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.
Hi everyone im on the middle of a messy thing i have 1 C2921-AX/K9 and 1 WS-C2960X-48TS-L connected to a RPS with two power supplies of 750watts but when i connect both and test the redundancy with the RPS unplugged the main power supply both the SW and de Router going off, the question is how many power supplies i need in what combination? 750 and 1100 or both of 1100 watts?
