Black box that allows just an A or B DC feed

["james" <hackerwacker () tarpit cybermesa com>]

I have a device that only has one DC power input. Is there a box that
can accept an A & B DC leg, keep both isolated, & and feed my
device with just A or B ? ie, if the A or B leg fails at the co-lo
this blackbox will switch to what ever leg is up. Quickly, I hope !

Or are there other ways to solve this issue ?
