Enable WWAN failover by selecting the Fail-over radio button.
Disable is selected by default, meaning there's no WWAN card
failover to the Altitude 4710's express card until Fail-over is
selected and the Altitude 4710 can read the express card's
modules during a boot up runtime operation.
Specify a username entered when connecting to the ISP
supporting the express card. When the Internet session begins,
the ISP authenticates the username. The username cannot
exceed 48 characters.
Specify a password entered when connecting to the ISP
supporting the express card. When the Internet session starts,
the ISP authenticates the password. The password cannot
exceed 40 characters.
Refer to the WWAN State field to discern whether the current
Altitude 4710 power budget supports WWAN failover support.
Click the WWAN IP Addresses button to specify additional static
IP addresses for the WWAN. Additional IP addresses are
required when users within the WWAN need dedicated IP
addresses, or when servers need to be accessed (addressed) by
the outside world. Only numeric, non-DNS names can be used.
Define a numerical IP address for this first WWAN remote
gateway. If the Access Point detects the loss of the wired WAN
connection, it establishes the WWAN connection and uses a
remote gateway to route traffic. Traffic that used go to the wired
WAN is redirected to the WWAN over this first choice remote
gateway.
Optionally define a numerical IP address for a second WWAN
remote gateway. If the Access Point detects the loss of the wired
WAN connection, it establishes the WWAN connection and uses
a remote gateway to route traffic. Traffic that used go to the wired
WAN is redirected to the WWAN over this second choice remote
gateway, if the first gateway is unavailable.
