Description
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.
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.
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.
