EX2200 Power System

 

Power Supply in EX2200 Switches

The power supply in EX2200 switches is built in along the rear panel of the chassis, with an AC power cord inlet or DC power terminals on the rear panel to connect power to the switch.

Table 1 lists the power consumed by each EX2200 switch model. The maximum power available on a PoE port is 30 W for switches running Junos OS Release 10.3 or later and 15.4 W for switches running Junos OS Release 10.2 or earlier.

Power Specifications for EX2200 Switches

This topic describes the power supply electrical specifications for EX2200 switches.

Table 2 provides the AC power supply electrical specifications for EX2200 switches.

Table 3 provides the DC power supply electrical specifications for EX2200 switches.

Specification

AC input voltage

100 through 240 VAC

AC input line frequency

50 Hz/60 Hz nominal

AC system current rating

  • 7 A at 100 VAC and 2.9 A at 230 VAC (for switches with ports equipped for PoE)

  • 1.8 A at 100 VAC and 0.5 A at 230 VAC (for switches with no ports equipped for PoE)

DC input voltage

36 through 75 VDC

DC input current

3.5 A maximum

Power supply output

100 W

Output holdup time

1 ms minimum

Note

EX2200 switches with DC power supply do not provide PoE.

Note

For DC power supplies, we recommend that you provide at least 3.5 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 allows the switch to function at full capacity using multiple power supplies.

AC Power Cord Specifications for EX2200 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

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 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.

Table 4 gives the AC power cord specifications for the countries and regions listed in the table.
