WARNING: To comply with GR-1089 requirements, all intra-building copper cabling
used for SFP+, QSFP+, and QSFP28 ports 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 “Connecting an MX10000 to Earth
Ground” on page 160 . 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 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 (21.1mm²) stranded wire.
•
The grounding cable that you provide for an MX10008 must be the same size 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 permitted by local code.
