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.
