PTX10008 Grounding Cable and Lug Specifications

You must install the router in a restricted-access location and ensure it is adequately grounded at all times. Proper grounding ensures your router is operating correctly and that it meets safety and electromagnetic interference (EMI) requirements. The PTX10008 modular chassis has a 2-hole protective grounding terminal on the rear of the chassis beneath the power supplies for grounding.

For AC powered systems, you must also use the grounding wire in the AC power cord along with the 2-hole lug ground connection. This tested system meets or exceeds all applicable EMC regulatory requirements with the 2-hole protective grounding terminal.


To comply with GR-1089 requirements, all intrabuilding copper cabling used for SFP+, QSFP+, and QSFP28 ports must be shielded and grounded at both ends.


Before router installation begins, a licensed electrician must attach a cable lug to the grounding cables that you supply. See Connect the PTX10008 Router to Earth Ground. A cable with an incorrectly attached lug can damage the router.

Before connecting the router to earth ground, review the following information:

  • Two threaded inserts (PEM nuts) are provided on the lower rear of the chassis for connecting the router to earth ground. The grounding points are spaced at 0.63 in. (16 mm) centers.

  • The chassis grounding lug required is a Panduit LCD4-14A-L or equivalent (provided). This lug accommodates 4 AWG (21.1mm²) stranded wire. The 4 AWG (21.1 mm²) stranded wire should be rated 90° C, or as permitted by local electrical code.


    Some early PTX10008 chassis shipped with chassis lugs rated for 6 AWG. If you plan to upgrade your power system to use JNP10K-PWR-DC2 power supplies at the high power setting (80 A), be sure your chassis lug is upgraded the Panduit LCD4-14A-L equivalent.

  • The grounding cable that you provide for a PTX10008 must be the same size or heavier than the input wire of each power supply.
