• LINK/ACT LED
The LINK/ACT LED shows the status of a standard network port. It is green if power is supplied
to the main unit and hub, and they are connected correctly (“LINK”). It blinks green while the
network port sends or receives data (ACT).
When the LED does not illuminate during “LINK,” check the condition and connection of
network cables. If there is nothing wrong with the cables, a defect is suspected in the network
(LAN) controller. In this case, contact your sales agent.
