Grounding the SRX650 Services Gateway

You ground the services gateway by connecting a grounding cable to earth ground and then attaching it to the chassis grounding points located on the right side of the device (if you are facing the front of the chassis) using two UNC 1/4-20 screws.

You must provide the following items:

• Two UNC 1/4-20 grounding screws
• Grounding cables
• Cable lugs (for example, Panduit LCC6-10A-L)

Caution: Before services gateway installation begins, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the services gateway (for example, by causing a short circuit).

To ground the services gateway:

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis. For more details, see Preventing Electrostatic Discharge Damage to the SRX650 Services Gateway.
2. Ensure that all grounding surfaces are clean and brought to a bright finish before grounding connections are made.
3. Connect the grounding cable to a proper earth ground.
4. Place the grounding cable lugs over the grounding points (sized for UNC 1/4-20 screws) on the side of the chassis.
5. Secure the grounding cable lugs to the grounding points, first with the washers, then with the screws.
6. Dress the grounding cable and verify that it does not touch or block access to the services gateway components and that it does not drape where people could trip on it.
