EX2300 Power System

Power Supply in EX2300 Switches

The power supply in EX2300 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.

Note:

After powering on the switch, wait for at least 60 seconds before powering it off. After powering off the switch, wait for at least 60 seconds before powering it back on.

Table 1 lists the power consumed by each EX2300 switch model.

Output holdup time

5 ms minimum
Note:

For DC power supplies, we recommend that you provide at least 2.8 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 enables the switch to function at full capacity using multiple power supplies.

AC Power Cord Specifications for EX2300 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.
