Power Specifications for EX3300 Switches

This topic describes the power supply electrical specifications for EX3300 switches.

Table 28 provides the AC power supply electrical specifications for EX3300 switches.

Table 29 provides the DC power supply electrical specifications for EX3300 switches.

Table 28: AC Power Supply Electrical Specifications for EX3300 Switches

Item

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

Table 29: DC Power Supply Electrical Specifications for EX3300 Switches

Item

Specification

DC input voltage

-43 through -75 VDC

DC input current

2 A maximum

Power supply output

100 W

Output holdup time

1 ms minimum

Note: For DC power supplies, we recommend that you provide at least 2.5 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.
