AC Power Cord Specifications for an EX4500 Switch
Each AC power supply for the EX4500 switch has a single AC appliance inlet located
on the power supply that requires a dedicated AC power feed. 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 switch. An AC
power cord connects each power supply to the power distribution panel.
Each detachable AC power cord is 2.5 meters (approximately 8 feet) long. The
appliance coupler at the female end of the cord inserts into the AC appliance inlet
on the faceplate of the AC power supply. The coupler type is C19 as described by
the International Electrotechnical Commission (IEC) standard 60320. The plug at the
