Grounding Cable and Lug Specifications for ACX7100-48L


For installations that require a separate grounding conductor to the chassis, you must ground the router properly before you connect power to ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements. To ground an ACX7100-48L router, connect a grounding cable to earth ground, and then attach the grounding cable to the chassis grounding points.


The router is a pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis and on the DC power supply module in addition to the grounding pin of the AC power supply cord. You must keep this separate protective earthing terminal permanently connected to earth ground for installations that require a separate grounding conductor to the chassis.


To comply with GR-1089 requirements, all intra-building copper cabling used for SFP+ and QSFP+ ports must be shielded and grounded at both ends.


Before you install the router, a licensed electrician must attach a cable lug to the grounding cables that you supply. See Connect Earth Ground to ACX7100-48L Routers. A cable with an incorrectly attached lug can damage the router.

Before you connect the router to earth ground, review the following information:

  • The grounding points are in the form of studs sized for M5 pan head screws. You need to provide these screws with integrated washers as we do not ship them in the accessory kit.

  • For ACX7100-48L routers, the grounding lug required is a Panduit LCD10-10A-L or equivalent. The grounding lug accommodates 14–10 AWG (2–5.3mm²) , stranded wire.
