Acx1000 And Acx1100 Dc Power Specifications - Juniper ACX1000 Hardware Manual

NOTE: In North America, AC power cords must not exceed approximately 14.75 ft (4.5 m) 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). You can order AC power cords
that are in compliance.
CAUTION: Power cords and cables must not block access to device components or
drape where people could trip on them.

ACX1000 and ACX1100 DC Power Specifications

The power supplies in ACX1000 and ACX1100 routers are built in along the front left panel of the
chassis with DC power terminals to connect power to the router. The power supplies are labeled PS0
and PS1.
When the ACX1100 router are operating normally and both power supplies are switched on, load
sharing between them occurs automatically. When one power supply fails or is turned off, the other
power supply immediately assumes the entire electrical load for the system. A single power supply can
provide full power for as long as the router is operational.
NOTE: When only one power supply is available on an ACX1100 router, we recommend that you
connect both the power inputs to the same source. That is, connect both the DC power inputs of
the ACX1100 router to the only available power supply. Doing so ensures that you get the
maximum amount of hold-up time during a power failure.
ACX1000 and ACX1100 routers support a wide range of voltage ranges as shown in
64.
