NOTE: A DC-powered router needs to be connected with the outdoor DC
power cord that is purchased from Juniper Networks, and which is
compatible with the ACX500 outdoor router. To supply sufficient power,
the DC input wiring on the facility DC source is capable of supplying at
least 5 A @–48 VDC per input for each power supply. We recommend
that the 48–VDC facility DC source should be equipped with a circuit
breaker rated at 5 A @–48 VDC minimum, or as required by local code.
For other nominal input voltages such as 24 VDC, –60 VDC, we recommend
that the circuit breaker rating be appropriately sized or rated, and as
required by local code.
Tighten the power cord plug screw.
