J4350 and J6350 Chassis
The J4350 and J6350 chassis is a rigid sheet metal structure that houses all the other
router components (see Figure 13 on page 28 through Figure 18 on page 30). The
chassis can be installed in many types of racks or cabinets. For information about
acceptable rack types, see “Rack Requirements” on page 104.
In addition to the features described in subsequent sections, the chassis includes the
following features:
■ Mounting brackets—One pair of metal brackets can be mounted at the front or
center of the chassis. Use the brackets for mounting the chassis in a rack or
cabinet.
■ Earthing terminals—Two protective earthing terminals, PEM nuts 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 terminals on the rear of the chassis are provided to connect the router to
ground (see Figure 14 on page 28). 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 247.
