ACX1000 and ACX1100 DC Power Specifications

Copyright © 2017, Juniper Networks, Inc.
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.
ACX1100 AC Power Specifications on page 59
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
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
Table 23 on page 61.
