SRX3400 Services Gateway Chassis Grounding Point


To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must properly ground the services gateway chassis before connecting power. See Grounding the SRX3400 Services Gateway for instructions.


Before services gateway installation begins, a licensed electrician must attach cable lugs to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the services gateway.

The services gateway chassis has one grounding point at the lower left corner of the back panel. The grounding point consists of two threaded holes spaced 0.625-in. (15.86-mm) apart (Figure 1). The grounding point holes fit M5 screws. The accessory box shipped with the services gateway includes the cable lug that attaches to the grounding cable and two M5 screws used to secure the grounding cable to the services gateway grounding point.

To ground the services gateway, you must connect a grounding cable to earth ground and then attach it to the chassis grounding point using the two screws provided.


Additional grounding is provided to an AC-powered services gateway when you plug its power supplies into grounded AC power receptacles.
