ON
This LED flashes once when the power supply is switched on. After the self-test, either
an error is output by a flashing light code or the device starts and the LED remains lit.
Standby
This LED shows that the unit is in stand-by mode. The
ELSA MicroLink Cable
is registered
with the cable network provider in this state, but there is no active connection to the local
network. In other words, no data can be exchanged between the Internet and the LAN
in this state.
The
ELSA MicroLink Cable
can be switched to this mode by configuring the function of
the power switch correspondingly and then actuating this switch on the rear of the unit.
Cable-Tx, -Rx,
-Sync, Reg’d

through combined blink codes, thus offering configuration troubleshooting information.
