Grounding The Mx240 Router - Juniper MX240 Hardware Manual

Grounding the MX240 Router

You ground the router by connecting a grounding cable to earth ground and then attaching it to the chassis
grounding points using UNC 1/4-20 two screws. You must provide the grounding cables (the cable lugs
are supplied with the router).
1. Verify that a licensed electrician has attached the cable lug provided with the router to the grounding
cable.
2. 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.
3. Ensure that all grounding surfaces are clean and brought to a bright finish before grounding connections
are made.
4. Connect the grounding cable to a proper earth ground.
5. Detach the ESD grounding strap from the site ESD grounding point.
6. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to
one of the ESD points on the chassis.
7. Place the grounding cable lug over the grounding points on the upper rear of the chassis. The bolts are
sized for UNC 1/4-20 bolts.
8. Secure the grounding cable lug to the grounding points, first with the washers, then with the screws.
9. Dress the grounding cable and verify that it does not touch or block access to router components, and
that it does not drape where people could trip on it.
