WARNING: DC-powered Services Routers are intended for installation only in a
restricted access location.

J6350 Power System

The J6350 Services Router uses either AC or DC power. You can install one or two
autosensing, load-sharing power supplies on the system board at the bottom of the
chassis, as shown in Figure 15 on page 28 or Figure 17 on page 29. The power
supplies distribute the different output voltages to the router components, depending
on their voltage requirements. When two power supplies are installed and operational,
they automatically share the electrical load.
For full redundancy, two power supplies are required. If a power supply stops
functioning for any reason, the second power supply instantly begins providing all
the power the router needs for normal functioning. It can provide full power
indefinitely.
Each power supply has an LED located to the upper right of the power supply
connector. Table 16 on page 37 describes the power supply LED.
For information about site power preparations, see "Power Guidelines, Requirements,
and Specifications" on page 107. For information about connecting the router to power
and ground, see "Connecting Power" on page 124.
Power supplies on J6350 Services Routers are hot-removable and hot-insertable. You
can remove and replace a redundant power supply without powering down the router
or disrupting the routing functions. To avoid electrical injury, carefully follow the
instructions in "Replacing Power System Components" on page 191.
NOTE: You cannot mix DC and AC power supplies in the same chassis.
