The shrouds on the AC cables and the receptacles on the card cage and power trays are keyed to ensure
proper connections. Do not attempt to insert cables into shrouds that are not keyed for them.
Note The AC power interconnect cables from each tray must be connected to the backplane. If the cables are
not connected, the power supply monitoring circuit will mistake this as voltage failure and will result in
