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. AC power cords connect each wiring tray to the power distribution panel.
Three detachable AC power cords, each 2.5 m (approximately 8 ft) long, are required
for each single-phase wiring tray. Depending on your configuration, these power cords
are supplied with your 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: The QFX3008-I Interconnect device is pluggable type A equipment
installed in a restricted-access location. It has a separate protective earthing
terminal provided on the chassis in addition to the grounding pin of the power
supply cord. This separate protective earthing terminal must be permanently
connected to earth.
WARNING: The AC power cord for the device is intended for use with the
device only and not for any other use.
