To select the cellular network
1. Select
2. At Mode, select from the drop-down list which mode you want for the
EXPLORER 540.
You have the following options:
• BGAN only (default): The EXPLORER 540 uses BGAN.
• Cellular modem preferred: The EXPLORER 540 uses the EXPLORER 540 Cellular
Modem with the cellular network when it is available, with BGAN as backup.
BGAN can still be used e.g. for remote access with SMS. If an EXPLORER 540
Cellular Modem is not connected, or if the cellular network does not work, the
BGAN connection is used. For details, see EXPLORER 540 operation in Cellular
modem preferred or External modem preferred mode on page 4-60.
• Cellular modem preferred (PRISM): Similar to Cellular modem preferred
mode, the EXPLORER 540 uses the EXPLORER 540 Cellular Modem with cellular
network when it is available, with BGAN as backup. But with PRISM, all traffic is
routed through a Multi-Path tunnel to/from a server, providing a continuous
connection through a single IP address, independent of the network technology
(cellular or BGAN).
For general information, see EXPLORER 540 operation in Cellular modem
preferred (PRISM) mode and External modem preferred (PRISM) mode on page 4-
62.
For setup of PRISM see To set up PRISM on page 4-56.
• External modem preferred: Same function as Cellular modem preferred, but
instead of the EXPLORER 540 Cellular Modem, an external modem is connected
via the LAN interface of the EXPLORER 540.
Important
• External modem preferred (PRISM): Same function as Cellular modem
preferred (PRISM), but instead of the EXPLORER 540 Cellular Modem, an external
modem is connected via the LAN interface of the EXPLORER 540. PRISM will
monitor the connection.
If you are using an external modem connected to the LAN interface, See also To set
up an external cellular modem on page 4-54.
3. Click Save.
4. When the modem is set up and connected, the opening page of the web interface
shows a new tile with the cellular connection. The "M" on the tile for the cellular
modem indicates that it is a cellular modem and not a BGAN connection.

(Control panel) > Terminal settings and locate Connection.
Before selecting this option, set up the Connection watchdog to
monitor the connection (see Connection watchdog (Link monitoring)
on page 4-34). Otherwise the terminal will not be able to detect if
the cellular connection is lost, and consequently will not switch
over to BGAN backup.
