Connecting the SRX320 Services Gateway Grounding Cable
You ground the services gateway by connecting a grounding cable to earth ground and
then attaching it to the chassis grounding point located on the back panel of the device
using one metric M5 x 0.8, 12-mm-long grounding screw.
You must provide the following items:
• M5 x 0.8, 12-mm-long grounding screw
• Grounding cables
•
Cable lugs (for example, Panduit LCC6-10A-L)
CAUTION: Before you connect power to the services gateway, 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 device:
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 SRX320 Services Gateway” on page 115 .
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 lug over the grounding point (sized for metric M5 x 0.8,
12-mm-long grounding screws) on the rear of the chassis.
