Juniper Networks EX4200 사용자 설명서

NOTE: The DC power supply in EX3200 and 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 @
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 allows the switch to function at full capacity using multiple power
supplies.

AC Power Cord Specifications for EX3200 and EX4200 Switches

Detachable AC power cords are supplied with the switch. 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 for the switches is intended for use with that switch
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.
