■ For J4350 and J6350 Services Routers—The grounding cables must be, at
minimum, 12 AWG single-strand wire cable. The grounding lug must be a
two-hole lug as shown in Figure 64 on page 126.
To ground the router before connecting power, you connect the grounding cable to
earth ground and then attach the lug on the cable to the chassis grounding point,
with the screw. (See “Connecting Power” on page 124.)
Connecting Power
J2320, J2350 and J4350 Services Routers have a single fixed power supply. J6350
Services Routers have one or two field-replaceable power supplies. For more
information about the J-series power specifications, see “Power Guidelines,
Requirements, and Specifications” on page 107.
WARNING: DC-powered Services Routers are intended for installation only in a
restricted access location.
Connecting AC Power
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. Additional grounding is provided to an AC-powered router when you plug
its power supply into a grounded AC power receptacle.
The AC power cord shipped with the router connects the router to earth ground when
plugged into an AC grounding-type power outlet. The router must be connected to
earth ground during normal operation.
For power cord requirements, see “AC Power, Connection, and Power Cord
Specifications” on page 109.
To connect AC power to the router:
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and
connect the strap to the ESD point on the chassis. For more information about
ESD, see “Preventing Electrostatic Discharge Damage” on page 251.
2. Use a grounding cable to connect the router to earth ground: (For cable
requirements, see “Chassis Grounding” on page 123.)
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.
