LED Configuration

State

Description


Device Server has

Authenticated with a

wireless network

When the RF_LINK LED is on the Airborne Device
Server module is associated to a wireless network. If

DHCP is enabled the module will request an IP
address, subnet, gateway and DNS server addresses.





Device Server

configured for network

communication

The WLN_CFG LED ON indicates the Airborne Device

Server module has installed a valid IP address and is
available for network communication.

It may take several seconds for the WLN_CFG LED to

turn ON after the RF_LINK LED is ON, this delay is due
to the DHCP lease process.

If static IP addressing is being used the WLN_CFG LED

will turn ON after network services are available on the

module. This will be a few seconds after POST has

turned ON.

TCP/IP connection has

been established with

the Airborne Device

Server Module

The COMM LED turning ON indicates that a TCP/IP

connection has been established between the Device
Server and a network device. This connection could be

a web interface, CLI interface or a data tunnel
connection.

The COMM LED will turn ON whether the TCP/IP

connection has been initiated by the Device Server or

from the network. If initiated from the Device Server
this indicates a successful connection with the target

Server has been made.
