Step 4: Connect the Grounding Cable
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to an approved site ESD grounding point. See the instructions for your site.
2. Connect the grounding cable to a proper earth ground.
3. Verify that a licensed electrician has attached the cable lug provided with the router
to the grounding cable.
4. Make sure that grounding surfaces are clean and brought to a bright finish before you
make grounding connections.
5. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis. For more information about ESD,
see the MX2020 3D Universal Edge Router Hardware Guide.
6. Place the grounding cable lug over the grounding points. The upper pair is sized for
UNC 1/4-20 bolts, and the lower pair is sized for M6 bolts.
7. Secure the grounding cable lug to the grounding points, first with the washers, and
then with the nuts (see Figure 30 on page 43).

8. Verify that the grounding cabling is correct, that the grounding cable does not touch
or block access to router components, and that it does not drape where people could
trip on it.
