EX4000 Power System

This topic describes the power system of EX4000 switches

Power Supply in EX4000 Switches

Juniper Networks ships EX4000 switches with inbuilt fixed power supplies. You power the switches by connecting the switches to an AC power source.

Specifications of the Power Cord for AC Power Supplies for EX4000 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 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 with Canadian Electrical Code (CEC) Section 4-010(3). The cords supplied with the switch are in compliance.

Table 3 gives the AC power cord specifications for the countries and regions listed in the table.
