[c-nsp] RPS 675 question

[andrew2 at one.net]

I'm getting ready to install some RPS 675's in order to dual cord some
3750's and ran across this in the manual:

"Do not use different power sources to power up the RPS and the connected
device.  If you connect to separate AC power sources, reset conditions might
occur."

Huh?  My intent is to plug the RPS into a different PDU than the actual
switches so that the switches can stay online in the event of a power
failure on their primary circuit.  Is this Cisco FUD or are there good
reasons I wouldn't want to plug an RPS into a different circuit than the
connected switches?

Thanks,

Andrew
