At former managed-hosting startup, we would deploy a pair of EMC symmetrixes into our DC cage as storage for our DB tier, with volumes mirrored over the pair. While equipment was being moved into the cage one day, someone accidentally banged the power-switch protection plate on one of the EMCs. Fortunately the power switch had to be held depressed for several seconds to turn off the equipment. Unfortunately, the protection plate itself got jammed in against power switch keeping it depressed. Hoisted by its own petard, as it were.
Good thing we deployed those EMCs in pairs. But then curiosity gets the better of a DC ops guy wondering how the plate got jammed. So he punches the plate on the 2nd EMC causing it to similarly jam and power-off. Doh.
When we told EMC about this flaw in the design, they deployed a fix to the production line - a rubber stopper under the plate next to the switch to protect the switch from the protection plate.
