LED Function
LAN Link Lit when the Ethernet interface is connected to a device (e.g., a hub),
which is generating link pulses. This LED is normally lit.
LAN Txd Lit when data is being transmitted over the Ethernet interface.
LAN Coll (yellow) Lit when a collision is detected on the Ethernet interface.
LAN Rxd Lit when data is being received on the Ethernet interface.
ISDN B2 Lit when data or voice calls are being transmitted over the B2 channel
of the ISDN interface.
ISDN B1 Lit when data or voice calls are being transmitted over the B1 channel
of the ISDN interface.
ISDN Active Lit when the BRI has successfully completed the exchange of INFO 1 and
INFO 2 signals, and INFO 3 and INFO 4 signals are present on the link.
This means that the ISDN interface is correctly connected to a working
NT device.
System (red) This LED is not normally lit. It is used to signal various system conditions
(e.g., when the processor executes the reboot sequence). Generally it
signals a possible fault condition, but it will light briefly during power-
up and operator initiated reboot.
Run Lit when the internal processor is executing code. If the processor stops
for any reason (a fault condition), then the LED will not be lit.
Power Lit when power is supplied and the router is switched on.
