NOTE: The DC power supply in EX4200 switches does not support Power over Ethernet (PoE);
you can use either an external power injector or an AC power supply to supply power to PoE
devices that you connect to the switch.
NOTE: For DC power supplies, we recommend that you provide at least 7.5 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 ensures that the switch
functions at full capacity using multiple power supplies.

AC Power Cord Specifications for EX4200 Switches

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:
with that power supply only and not for any other use.
NOTE: In North America, AC power cords must not exceed 4.5 meters 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.
