AC Power Cord Specifications for EX2300 Switches
68
NOTE:
For DC power supplies, we recommend that you provide at least 2.8 A
at 48 VDC and use a facility circuit breaker rated for 10 A minimum. Doing so
enables you to operate the switch in any configuration without upgrading
the power infrastructure, and enables the switch to function at full capacity
using multiple power supplies.

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.
CAUTION:
The AC power cord provided with each power supply is intended
for use with that power supply only and not for any other use.
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 cords supplied with the switch are in
compliance.
