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 male end of the
power cord fits into the power source outlet that is standard for your geographical location.
NOTE:
In North America, AC power cords must not exceed 4.5 meters
(approximately 15 feet) in length, to comply with National Electrical Code
(NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52 and Canadian Electrical
Code (CEC) Section 4-010(3) standards. The cords shipped with the switch
are in compliance with these standards.
