5. Firewall, Failover and OOB Access 5.6.4 Dual SIM Failover Some console server models allow you to insert two SIM cards so you can selectively connect to two carrier networks. The dual SIM failover feature allows the cell modem to selectively failover to the secondary SIM when communications over the primary SIM fails. To configure dual SIM failover, you need to: • Choose which of the SIMs is to be the Primary, and the other SIM will be the secondary/failover. It is recommended that an explicit slot is chosen, rather than leaving it on Automatic. Select Internal Cellular Modem panel on the System: Dial menu nominate which slot (Top or Bottom) contains the Primary. • Check Enable SIM Failover. • Specify how the device will Failback from the failover SIM to the Primary SIM. There are two options o The 'On Disconnect' failback option will failback to the Primary SIM only after the connection on the failover SIM has failed its ping test. o The 'On Timeout' failback option will failback to the Primary SIM after the connection on the failover SIM has been up for the timeout period. The timeout period is either the default value of 600 seconds if the Failback Timeout field is left empty or the number of seconds you have specified in the Failback Timeout field. • Next, you will need to configure each SIM connection with as much information (e.g. APN, etc.), such that it will make a successful connection, assuming sufficient signal strength from the cell service provider. • Enter a Failback Test IP address for each SIM. This IP address is used to ping test the status of the cell modem connection and to determine if SIM failover or failback is to take place. • Configuring DDNS and the Modem Watchdog are optional. DDNS, when configured, will be applied to the cell modem dial out connection regardless of which SIM is currently in use. Dual SIM failover is for dial out connections only. 5.6.5 Automatic SIM Slot Detection If a single SIM card is used in a Dual SIM slot product, the default configuration for the product is to automatically detect which slot the SIM is in and select that slot. If both slots are populated, the bottom SIM slot will be used in preference. 88

5.6.4 Dual SIM Failover
Some console server models allow you to insert two SIM cards so you can selectively connect to two carrier networks. The
dual SIM failover feature allows the cell modem to selectively failover to the secondary SIM when communications over the
primary SIM fails.
To configure dual SIM failover, you need to:
• Choose which of the SIMs is to be the Primary, and the other SIM will be the secondary/failover. It is recommended that an
explicit slot is chosen, rather than leaving it on
Automatic
. Select
Internal Cellular Modem
panel on the
System: Dial
menu nominate which slot (
Top
or
Bottom
) contains the Primary.
• Check
Enable SIM Failover
.
• Specify how the device will
Failback
from the failover SIM to the Primary SIM. There are two options
o The ‘
On Disconnect
’ failback option will failback to the Primary SIM only after the connection on the failover SIM has
failed its ping test.
o The ‘
On Timeout
’ failback option will failback to the Primary SIM after the connection on the failover SIM has been up
for the timeout period. The timeout period is either the default value of 600 seconds if the
Failback Timeout
field is left
empty or the number of seconds you have specified in the
Failback Timeout
field.
• Next, you will need to configure each SIM connection with as much information (e.g. APN, etc.), such that it will make a
successful connection, assuming sufficient signal strength from the cell service provider.
• Enter a Failback Test IP address for each SIM. This IP address is used to ping test the status of the cell modem connection
and to determine if SIM failover or failback is to take place.
• Configuring DDNS and the Modem Watchdog are optional. DDNS, when configured, will be applied to the cell modem dial
out connection regardless of which SIM is currently in use. Dual SIM failover is for
dial out
connections only.
5.6.5 Automatic SIM Slot Detection
If a single SIM card is used in a Dual SIM slot product, the default configuration for the product is to automatically detect
which slot the SIM is in and select that slot. If both slots are populated, the bottom SIM slot will be used in preference.
