•
Use the grounding cable (yellow-green grounding cable) provided with the switch.
•
Connect the grounding cable to the earthing system in the equipment room. Do not connect it to
a fire main or lightning rod.
You can ground the switch by connecting the grounding cable to a grounding strip in the equipment
room or the grounding strip on the rack.
To connect the grounding cable to a grounding strip:
1.
Unpack the grounding cable.
The grounding cable provided with the switch is compliant with the NEBS standards. The
two-hole grounding lug of the grounding cable is used for connecting the chassis. The ring
terminal of the grounding cable is used for connecting the grounding strip.
2.
As shown by callouts 1 and 2 in
, remove the grounding screws from the grounding
holes at the rear of the chassis.
A grounding sign is provided with the grounding holes.
3.
Use grounding screws to attach the two-hole grounding lug of the grounding cable to the
chassis, as shown by callouts 3 and 4 in
The recommended torque for the grounding screws is 30 kgf-cm (2.94 Nm).
