Power Specifications and Requirements for EX-series Switches

This topic describes power specifications and requirements for power supplies for EX 3200 and EX 4200 switches.

Table 1 provides the AC power supply electrical specifications for EX 3200 and EX 4200 switches.

Table 2 provides the DC power supply electrical specifications for EX 3200 and EX 4200 switches.

Table 1: AC Power Supply Electrical Specifications for EX 3200 and EX 4200 Switches

Item

Specification

AC input voltage

100 through 240 VAC

AC input line frequency

50 through 60 Hz

AC system current rating
  • 4 A (for switches with 8 ports equipped for Power over Ethernet (PoE) or the switch with 24 100Base-FX/1000Base-SX SFP ports)
  • 7 A (for switches with 24 ports equipped for PoE)
  • 12 A (for switches with 48 ports equipped for PoE)

Table 2: DC Power Supply Electrical Specifications for EX 3200 and EX 4200 Switches

Item

Specification

DC input voltage

36 through 72 VDC

DC input current

7 A maximum

Power supply output

190 W

Output holdup time

1 ms minimum

Note: The DC power supply in EX 3200 and EX 4200 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.
