J2320 and J2350 Chassis
The J2320 and J2350 chassis is a rigid sheet metal structure that houses all the other
router components (see Figure 1 on page 14 through Figure 7 on page 17). The
chassis can be installed in many types of racks or cabinets. For information about
acceptable rack types, see “Rack Requirements” on page 102.
In addition to the components described in subsequent sections, the chassis includes
the following components:
■ Mounting brackets—One pair of metal brackets can be mounted at the front or
center of the chassis for mounting the chassis in a rack or cabinet.
■ Earthing terminal—A protective earthing terminal and a PEM nut at the rear of
the chassis ensure safe dissipation of static electricity in all situations.
■ ESD point—One electrostatic discharge (ESD) point, a banana plug receptacle at
the front of the chassis, minimizes the risk of electrical discharge in potentially
hazardous environments.
CAUTION: Before removing or installing components of a functioning router, attach
an ESD strap to an ESD point and place the other end of the strap around your bare
wrist. Failure to use an ESD strap could result in damage to the router.
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 (see Figure 3 on page 15). Additional grounding is provided to an AC-powered
router when you plug its power supply into a grounded AC power receptacle.
For additional safety information, see “Safety and Regulatory Compliance
Information” on page 245.
