J2320, J2350, J4350, and J6350 Services Router Getting Started Guide

■For J2320 and J2350 Services Routers—The grounding cables must be, at minimum, 14 AWG single-strand wire cable. The grounding lug must be a ring-type, vinyl-insulated TV14-8R lug as shown in Figure 62 on page 125 and Figure 63 on page 126.

■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.
