CHAPTER 6: Grounding and Powering the Gateway
38 Connecting the Grounding Wire Copyright © 2010, Juniper Networks, Inc.
To ground the gateway:
1. Verify that a licensed electrician has connected a grounding lug to the grounding cable.
2. Ensure that the grounding surface is clean and brought to a bright finish before grounding
connections are made.
3. Locate the two grounding studs on the right side of the front panel on the gateway.
4. Remove the M4 size nut and the locking washer from the grounding studs.
5. Strip one end of the grounding wire. The amount of covering to be stripped varies depending
on the lug you attach to the wire.
6. Insert the stripped end of the grounding wire into the open end of the 5/8” pitch twin hole
grounding lug and crimp the grounding wire securely to the lug (see Figure 22 on page 39). Use
the lug manufacturer’s recommended crimping tool to ensure a proper crimp.
7. Attach the grounding lug to the threaded holes on the chassis and secure them first with
washers and then with M4 size nut.
8. Connect the other end of the grounding wire to a proper earth ground.
9. Verify that it does not touch or block access to the gateway and that it does not drape where
people could trip on it.
