Connecting an MX10016 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 attached 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 54 on page 148 ).
Before you connect the protective earthing terminal of an MX10016 to earth ground, 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. See “Installing
an MX10016 into a Four-Post Rack” on page 139
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 MX10016 (not provided)—The grounding cable must be a 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
MX10016 router chassis next to PSU 9, 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 MX10016 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
“MX10016 Power Cord Specifications” on page 104 ).
To connect an MX10016 chassis to earth ground:
1. Verify that a licensed electrician has attached the grounding lug (provided in the accessory kit) to the
grounding cable.
2. Connect the other end of the grounding cable to a proper earth ground, such as the rack in which the
