Juniper EX2300 Series Hardware Guide

Table 16: DC Power Supply Electrical Specicaons for EX2300 Switches (Except EX2300-C,
EX2300-24MP, and EX2300-48MP Switches) (Connued)
Item Specicaon
Power supply output 100 W
Output holdup me 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 conguraon without upgrading the power infrastructure, and enables the switch to
funcon at full capacity using mulple power supplies.
AC Power Cord Specicaons for EX2300 Switches
A detachable AC power cord is supplied with the AC power supplies. The coupler is type C13 as
described by Internaonal Electrotechnical Commission (IEC) standard 60320. The plug at the male end
of the power cord ts into the power source outlet that is standard for your geographical locaon.
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
Naonal Electrical Code (NEC) Secons 400-8 (NFPA 75, 5-2.2) and 210-52 and Canadian
Electrical Code (CEC) Secon 4-010(3). The cords supplied with the switch are in compliance.
Table 17 on page 50 gives the AC power cord specicaons for the countries and regions listed in the
table.
