The following information should help you diagnose basic setup or
installation problems.
Power LED is OFF: If the Power LED fails to light up, then check if the power
cord is properly connected to external power adapter and the power
source. Make sure the DC power jack is firmly plugged into the power
socket of the switch.
Link/Activity (LNK/ACT) is OFF: If the LNK/ACT LED fails to light up when
connected to devices, then ensure that the network device attached to
the switch is powered on. You can also check the network cable and
ensure it is properly connected to the switch and the network device. Lastly,
check the network cable and ensure the UTP cable complied with EIA/TIA
568 and Category 5 specifications.
