MX10004 Grounding Cable and Lug Specifications

The router must be adequately grounded before power is connected to ensure proper operation and to
meet safety and electromagnetic interference (EMI) requirements. To ground an MX10004 chassis,
connect a grounding cable to earth ground and then attach it to the chassis grounding point on the rear
of the chassis beneath.
You must install the MX10004 in a restricted-access location and ensure that the chassis is always
properly grounded. The MX10004 has a two-hole protective grounding terminal provided on the
chassis. Under all circumstances, use this grounding connection to ground the chassis. For AC-powered
systems, you must also use the grounding wire in the AC power cord along with the two-hole grounding
lug connection. This tested system meets or exceeds all applicable EMC regulatory requirements with
the two-hole protective grounding terminal.
WARNING: To comply with GR-1089 requirements, all intrabuilding copper cabling
used for SFP+, QSFP+, and higher must be shielded and grounded at both ends.
CAUTION: Before router installation begins, a licensed electrician must attach a cable
lug to the grounding cables that you supply. See
Earth Ground" on page
router.
Before you connect the router to earth ground, review the following information:
• Two threaded inserts (PEM nuts) are provided on the lower rear of the chassis to connect the router
to earth ground. The protective earthing terminals are spaced at 0.63 in. (16 mm) centers.
• The grounding lug required is a Panduit LCD6-10A-L or equivalent (provided). The grounding lug
accommodates 6 AWG (13.3 mm²) stranded wire. If one or more JNP10K-PWR-DC2 power supplies
are installed in the chassis and set for high input (80 A), use the Panduit LCD4-14A-L or equivalent
(provided). This lug accommodates 4 AWG (21.1 mm²) stranded wire. The 4 AWG (21.1 mm²)
stranded wire should be rated 90° C or as specified by the local electrical code.
• The grounding cable that you provide for an MX10004 must be the same size as, or heavier than, the
input wire of each power supply. Minimum recommendations are 6 AWG (13.3 mm²) stranded
copper wire, Class B; 90° C wire, or as specified by local code.
