LED Function
LAN Data 1 Lit when data is being transmitted over the Ethernet 1 interface.
LAN Link 1 Lit when the Ethernet 1 interface is connected to a device (e.g., a hub),
which is generating link pulses. This LED is normally lit.
LAN Data 0 Lit when data is being transmitted over the Ethernet 0 interface.
LAN Link 0 Lit when the Ethernet 0 interface is connected to a device (e.g., a hub),
which is generating link pulses. This LED is normally lit.
WAN Rxd Lit when data is being received over the synchronous interface.
WAN Txd Lit when data is being transmitted over the synchronous interface.
WAN Active Lit when a higher layer module (e.g., PPP) has attached to the interface
and DCD or its analog ("I" for X.21) is active. This usually indicates that
the NTU or DSU/CSU is connected to a correctly provisioned data circuit.
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.
