Power Specifications and Requirements for EX3200 and EX4200 Switches

This topic describes power specifications and requirements for power supplies for EX3200 and EX4200 switches.

Table 1 provides the AC power supply electrical specifications for EX3200 and EX4200 switches.

Table 2 provides the DC power supply electrical specifications for EX3200 and EX4200 switches.

Table 1: AC Power Supply Electrical Specifications for EX3200 and EX4200 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 EX3200 and EX4200 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 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.
