Corrective Action
Ensure the AC plug is plugged into an electrical outlet not
powered by a wall switch.
Verify that the AC power outlet has power, such as
plugging in some other AC device. If nothing works,
contact an electrician or use another power outlet.
Verify that the DC plug is plugged into the power jack
marked DC 5.1V
Ensure that one end of the Ethernet cable is plugged into
the port marked LAN on the front of the Gateway and that
the other end is plugged into your office LAN.
Confirm that the Ethernet port light next to the Ethernet
port on the Gateway is green. If it is not, unplug the cable
and plug it in again.
There may be a problem with the office network. Check if
other network devices, such as computers, are
communicating with the network. If not, then contact your
IT administrator.
