LEDs and What They Mean

System LEDs on its front panel indicate the router's operational status.

LED

Function

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.

ISDN B1

Lit when data or voice calls are being transmitted over the B1 channel

of the ISDN interface.

ISDN B2

Lit when data or voice calls are being transmitted over the B2 channel

of the ISDN interface.

LAN Coll (yellow) Lit when a collision is detected on the Ethernet interface.

LAN Data 0

Lit when data is being transmitted over the Ethernet 0 interface.

LAN Data 1

Lit when data is being transmitted over the Ethernet 1 interface.

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 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.

LAN Rxd

Lit when data is being received on the Ethernet interface.

LAN Txd

Lit when data is being transmitted over the Ethernet 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.

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.

WAN ISDN

Lit when data is being transmitted or received over the ISDN interface.

WAN Rxd

Lit when data is being received over the synchronous interface.

WAN Syn

Lit when data is being transmitted or received over the synchronous

interface.

WAN Txd

Lit when data is being transmitted over the synchronous interface.

Function

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

reboots.

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.

Lit when power is supplied and the router is switched on.
