Most sites distribute power through a main conduit that leads to frame-mounted power
distribution panels, one of which can be located at the top of the rack that houses the
device. Three AC power cords connect each wiring tray to the power distribution panel.
Six detachable AC power cords, each 2.5 m (approximately 8 ft) long, are supplied with
the device. The appliance coupler at the female end of the cord inserts into one of the
three appliance inlets on the faceplate of the single-phase wiring tray. The coupler is
type C19 as described by International Electrotechnical Commission (IEC) standard
60320. The plug at the male end of the power cord fits into the power source receptacle
that is standard for your geographical location.
WARNING: TheQFX3008-IInterconnectdevice is pluggabletype A equipment
installed in a restricted-access location. It has a separate protective earthing
terminalprovided on the chassisin addition to the grounding pin of the power
supply cord. This separate protective earthing terminal must be permanently
connected to earth.
