Opengear's Operations Managers have the option to come with cellular capabilities. The following steps will enable this functionality.
Log into your Operations Manager
If this is the first login, you will need to reset your root user password after logging in.
Enable and Configure the Cellular Interface
Select Configure > Network Connections > Network Interfaces
Select Cellular Interface (LTE)
Select Enabled and confirm that you would like to proceed with this action.
Once you have enabled the interface, you are presented with the connection configuration page. Here you will enter any details provided by your carrier. These settings vary by carrier and plan and may include:
- Username & password
- PIN code
- IP Type (v4v6, v4, or v6)
Ensure you have checked "Interface Enabled" and select Apply.
After completion of these steps, you will be able to see the connection details on Network Interfaces page.
Enable Cellular Failover
Once you have configured your cellular connection and verified it has connected to the carrier network, you can enable the Operations Manager to failover to the carrier network if the primary network becomes unavailable. You will set an address for the Operations Manager to attempt to reach and the interface to use for this test. If the test fails, the Operations Manager will automatically switch to the cellular interface for connectivity.
Select Configure > Network Resilience > OOB Failover
Select "Enabled", set the probe address and the probe interface and then select apply.
After enabling failover, you can view the status on this page at any time.
Enabling IP Passthrough
Operations Manager's also provide the ability to passthrough the cellular connection to downstream devices for network operations. This is especially usefull if a remote site goes offline and users need network access.
To enable IP Passthrough, Select Configure > Network Resilience > IP Passthrough.
Select "Enable" and the interface that the Operations Manager will offer the DHCP lease to. Optionally, you may provide the MAC address of the Downstream interface that will lease the address.
As the connection will now be handled by a downstream device, if you would like to access the Operations Manager over the cellular interface, Opengear provides the ability to have an intercept port for both SSH and HTTPS. Entering these ports will ensure you can access SSH and HTTPS on the device directly.
