Connecting DC Power
CAUTION: If your J6350 Services Router includes an optional redundant DC power
supply, connect each of the two power supplies to different input power sources.
Failure to do so makes the router susceptible to total power failure if one of the
power supplies fails.
The router must be connected to earth ground during normal operation.
The protective earthing terminal on the rear of the chassis is provided
to connect the router to ground.
For DC cable requirements, see “DC Power, Connection, and Power
Cable Specifications” on page 77.
To connect DC power to the router:
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strip to the ESD point on the chassis. For more information about
ESD, see “Preventing Electrostatic Discharge Damage” on page 205.
2. Use a grounding cable to connect the router to earth ground: (For cable
requirements, see “Chassis Grounding” on page 86.)
a. Verify that a licensed electrician has attached an appropriate grounding
cable lug to the grounding cable.
b. Connect one end of the grounding cable to a proper earth ground, such as
the rack in which the router is installed.
