2. Verify the Switch Passes Self Test
Before mounting the switch, verify it is working properly by plugging it into a
power source and confirming that it passes self test.

supplied with the switch to the power connector on the back of the switch,
and then into a properly grounded electrical outlet.
For the HP 1820 8-port switches, connect the AC/DC adapter’s power cord
to the power connector on the back of the switch, and then plug the AC/
DC power adapter into a nearby properly grounded electrical outlet.
