System Monitor

The System Monitor page is used to configure the behaviour of the Periodic Ping

monitor function.

Figure 31: System Monitor Settings

The Periodic Ping Reset Monitor configures the AirCard Hub to transmit controlled

ping packets to 2 specified IP addresses. If the AirCard Hub does not receive

responses to the pings, the AirCard Hub reboots.

This works as follows:

1. After every “Periodic PING Timer” configured interval, the AirCard Hub sends 3

consecutive pings to the “Destination Address”.

2. If all 3 pings fail, the AirCard Hub sends 3 consecutive pings to the “Second

Address”.

3. The AirCard Hub then sends 3 consecutive pings to the “Destination Address”

and 3 consecutive pings to the “Second Address” every “Periodic PING

Accelerated Timer” configured interval.

4. If all accelerated pings in step 3 above fail, the number of times configured in

“Fail Count”, the AirCard Hub reboots.

Note: Do not set the “Periodic PING Timer” to a value less than 60 seconds; this is to allow the

AirCard Hub time to reconnect to the 3G/4G network following a reboot.

5. If any ping succeeds, the AirCard Hub returns to step 1 and does not reboot.

To disable the Periodic Ping Reset Monitor set “Fail Count” to 0.

Note: The traffic generated by the periodic ping feature is counted as chargeable usage;

please keep this in mind when selecting how often to ping.

Configure a Forced Reset
The AirCard Hub can optionally be configured to automatically reboot after a period of

time specified in minutes. This ensures that the AirCard Hub will restart if some

anomaly occurs. This is useful in remote installations.

This feature is available by clicking Services > System Monitor.
The default value is 0, which disables the Forced Reset Timer. The maximum value is

65535 minutes.
