Grounding The Chassis - HP Aruba 6400 Series Installation And Getting Started Manual

Grounding the chassis

CAUTION: To protect the switch from hazards such as lightning shocks, interferences, and ESD
discharges, reliably ground it. The switch is grounded through the safety wire in the power
cords. If there is any doubt about the reliability of the grounding through the power mains,
Aruba recommends an independent grounding connection for the chassis. Note the location of
the grounding lug.
