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. The
grounding post is M-8 with 1.25mm pitch threads. 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 ground-
ing post. Make sure the connections 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.
