3. For the HP 1820 8-port switches, use the included cable tie to secure the
power cord to the switch.

5. Connect the Network Cables

Connect the network cables, from the network devices or your patch panels,
to the fixed RJ-45 ports on the switch or to any SFP transceivers you have
installed in the switch.
When a network cable from an active network device is connected to the port,
the port LEDs for that port should go on. If the port LEDs do not go on when
the network cable is connected to the port, see
on page 4-2.
