Ground Connections
Make sure to connect the ground post to a valid electrical ground. Use a grounding lug and a
ground wire of sufficient capacity to safely convey a potential discharge. A ground wire of AWG 6
or 4mm diameter is recommended for grounding this device. The chassis is concurrently grounded
through each of the PSUs. Only connect the PSU cords to properly grounded outlets. Do not rely
on the PSU grounds. It is absolutely necessary to connect the grounding post. Make sure the con-
nections are solid and permanent. If you choose to not use the ground screw, make sure that the
rack is properly grounded and that there is a valid ground connection between the chassis of the
switch and the rack. Test the ground using an Ohm meter.
