Connecting an MX10000 to Earth Ground
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you
must connect the chassis to earth ground before you connect it to power.
For installations that require a separate grounding conductor to the chassis, you must attach a protective
earthing terminal bracket on the chassis. There are mounting holes for the terminal bracket on the left-rear
side of the chassis to connect to the earth ground (see Figure 65 on page 162 ).
Before you connect earth ground to the protective earthing terminal of an MX10008, or MX10016, ensure
that a licensed electrician has attached an appropriate grounding lug to the grounding cable.
CAUTION: Using a grounding cable with an incorrectly attached lug can damage the
router.
NOTE: Mount your router in the rack before attaching the grounding lug to the router. For the
MX10008 and MX10016, see:
•
Installing the MX10008 into a Rack on page 143
•
Installing an MX10016 into a Four-Post Rack
•
Ensure that you have the following parts and tools available:
•
An electrostatic discharge (ESD) grounding strap (provided).
•
Protective earthing terminal lug (provided).
•
Grounding cable for your MX10008 (not provided)—The grounding cable must be 6 AWG (13.3 mm²),
minimum 90° C wire, or as permitted by the local code.
•
Grounding lug for your grounding cable (provided)—This bracket attaches to the lower left corner of the
MX10008 router chassis next to PSU 5, providing a protective earthing terminal for the router. The
grounding lug required is a Panduit LCD6-10A-L or equivalent.
•
A Phillips screwdriver to tighten the two screws that are mounted on the chassis.
An AC-powered MX10008 gains additional grounding when you plug the power supply in the router into
a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See
“MX10000 Power Cables Specifications” on page 107 .
