Juniper PTX5000, Hardware Manual

Page: 239 / 721

To ground the PTX5000 (see Figure 86 on page 221 ):
1. Connect the grounding cable to a proper earth ground.
2. Verify that a licensed electrician has attached the cable lug provided with the PTX5000 to the
grounding cable.
3. Make sure that grounding surfaces are clean and brought to a bright finish before grounding
connections are made.
4. Place the grounding cable lug over the grounding points on the bottom rear of the chassis. The top
pair is sized for M6 screws, and the bottom pair is sized for UNC 1/4-20 screws. You can use either
pair of grounding points. UNC 1/4-20 screws are provided in the accessory kit.
5. Secure the grounding cable lug to the grounding points, first with the washers, then with the screws.
6. Verify that the grounding cabling is correct, that the grounding cable does not touch or block access
to the PTX5000 components, and that it does not drape where people could trip on it.
