Does the Cisco ISR 4331 support an external RPS Unit like the 2300 or 675 RPS? I know it does not have it internally but am wondering about external support. Or do I HAVE to move up to the 4400 series to get any sort of redundant power supply?
The data sheet does not have any info on RPS. So, I would think it is not supported and you would need to move up to the 4400 series to get the redundant PSU. Just to be sure, you can also check with your Cisco sales rep.
