Juniper MX10004 - MX10004 Grounding Cable and Lug Specifications

MX10004 Grounding Cable and Lug Specicaons
The router must be adequately grounded before power is connected to ensure proper operaon and to
meet safety and electromagnec interference (EMI) requirements. To ground an MX10004 chassis,
connect a grounding cable to earth ground and then aach it to the chassis grounding point on the rear
of the chassis beneath.
You must install the MX10004 in a restricted-access locaon and ensure that the chassis is always
properly grounded. The MX10004 has a two-hole protecve grounding terminal provided on the
chassis. Under all circumstances, use this grounding connecon 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 connecon. This tested system meets or exceeds all applicable EMC regulatory requirements with
the two-hole protecve 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 installaon begins, a licensed electrician must aach a cable
lug to the grounding cables that you supply. See "Connect the MX10004 Router to
Earth Ground" on page 135. A cable with an incorrectly aached lug can damage the
router.
Before you connect the router to earth ground, review the following informaon:
• Two threaded inserts (PEM nuts) are provided on the lower rear of the chassis to connect the router
to earth ground. The protecve 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 specied 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 recommendaons are 6 AWG (13.3 mm²) stranded
copper wire, Class B; 90° C wire, or as specied by local code.
