NOTE: The router is rated for ambient temperature of 149° F (65° C). Use power cord of
appropriate temperature rating.
ACX500 DC Power Specifications
The power supplies in ACX500 routers are built in along the front left panel of the chassis with DC
power terminals to connect power to the router. The ACX500 indoor router power supply inputs are
labeled INPUT 1 and INPUT 2. On the ACX500 outdoor routers, there are no labels for the DC power
supply inlet.
NOTE: For the ACX500 outdoor routers, use the power cord that is purchased from Juniper
Networks, and which is compatible with the ACX500 outdoor routers. Using a power cord other
than that is provided by Juniper Networks with the router can damage the power terminal. The
nominal rating of the DC power source are +24 VDC, –48 VDC, and –60 VDC. These power
cords are specifically designed to be used only with the specified ACX500 outdoor routers.
ACX500 routers support a wide range of voltage ranges as shown in
