AC Power Cord Specifications for an EX4550 Switch
A detachable AC power cord is supplied with the AC power supplies. The coupler is type
C13 as described by 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 14.75 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). The cord supplied with the switch is in
compliance.
