That's no problem. Just plug the interrrupter in backwards and the line cards upside-down and it works fine. Oh, and don't forget to connect your ground to the hot side of the power supply to keep things consistent.
I have a better idea. Mount it on the inside of the closet door so that when the cleaning people slam it after taking their brooms, mops and buckets out, all of the line cards will fall out. You pull off the cover to test for troubles and end up with a dozen line cards on the floor. Of course a snake inside of the cover would probably be less of a shock.
Now I know what that stupid locking bar with ten screws was for... It was to protect the system from cleaning people when racks are mounted on doors!
