Cisco 2800 RPS

So I'm trying to rearrange some equipment to consolidate a few racks in the Data Center and one of the last pieces to move is a Cisco 2811 Router. If possible I would like to be able to do this without powering it down.
My idea is, although we don't have an RPS675, to plug another Cisco power supply directly into the external RPS port on the 2811 so I can unplug the other port and move it without losing electricity. From researching this, Cisco states the RPS675 unit is hot swappable, but in this case we don't have that unit. Can I plug a power supply directly into the external RPS port without frying the router?

What power supply do you have?

It can't take that long to unrack and rerack a 2811 though. You can't afford 15 minutes downtime?

Even if you do have a RPS connected, how are you going to move all your LAN/WAN cabling?

It's a power supply from an ASA that matches power specifications. In terms of cabling, it would be much faster to unplug a patch cord and swing around to the next rack and only drop connectivity for 10 seconds rather than 15 minutes.
Being down for 15 minutes to move? Sounds nice, but we're a 24/7 establishment and this is the router that connects us to corporate and they've refused the downtime regardless of when I asked to move it. I love the big wigs.

Ah but if you must have that uptime then they should have let you buy a RPS in the first time

About using a non RPS PSU with the 2811, I wouldn't risk it. There is a certain amount of signalling that goes on between the device and the RPS. The ISRs use a smaller plug that doesn't do a lot of this management but there is still something that goes on between them.

I agree with tiersten - No way would I risk it. You're looking at a lot more then 15 minutes if you run into a problem. Sneak in like a ninja in the middle of the night
