WARNING: The switch is pluggable type A equipment installed in a
restricted-access location. It has a separate protective earthing terminal
(sized for UNC 1/4-20 ground lugs) provided on the chassis in addition to the
grounding pin of the power supply cord. This separate protective earthing
terminal must be permanently connected to earth.
CAUTION: Power cords must not block access to switch components. We
recommend that you route all AC power cord cables through the power cord
tray provided with the switch.
