Grounding the router
CAUTION:
•
Reliably grounding the router is crucial to lightning protection and EMI protection. Ground the
router reliably before you use it.
•
To guarantee the grounding effect, use the grounding cable (yellow-green grounding cable)
provided with the router.
•
Connect the grounding cable to the earthing system in the equipment room. Do not connect it to
a fire main or lightning rod.
•
Make sure the ground point on the rack is connected reliably to a grounding strip in the
equipment room.
IMPORTANT:
The grounding cable provided with the router is NEBS compliant. Connect the two-hole grounding
lug of the grounding cable to the chassis and the ring terminal to a grounding strip.
To ground the router:
1. Remove the grounding screws from the grounding point on the chassis.
2. Use the grounding screws to attach the two-hole grounding lug of the grounding cable to
grounding point on the chassis.
3. Connect the ring terminal of the grounding cable to the grounding point on the rack.
