Grounding the switch
WARNING!
For the safety of operators and equipment, securely ground the switch. Make sure the resistance reading
between the switch chassis and the ground is less than 1 ohm.
CAUTION:
Connect the grounding cable to the earthing system in the equipment room. Do not connect it to a fire main
or lightning rod.
Most racks are equipped with a grounding strip. You can connect the yellow-green grounding cable of
the switch to the grounding strip.
NOTE:
Use the supplied grounding cable (CAT 6 cable with dual-hole OT terminals).
To connect the grounding cable:
1. Remove the two grounding screws from the switch chassis.
2. Use the grounding screws to attach one end of the grounding cable to the chassis.
3. Connect the other end of the grounding cable to the grounding strip of the rack in the same way.
