TRB145 Auto Reboot

Summary

Various automatic device reboot scenarios can be configured in the Auto Reboot section. Automatic reboots can be used as a prophylactic or precautionary measure that ensures the device will self-correct some unexpected issues, especially related to connection downtime.

This chapter is an overview of the Auto Reboot section of TRB145 devices.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

Ping/Wget Reboot

The Ping/Wget Reboot functions periodically send ICMP or Wget requests to a specified IP address or host and waits for a response. If no response is received, the device will attempt the same action a defined number of times at a defined frequency. If there is still no response, the device will execute the specified action (reboot, by default).

The Ping/Wget Reboot section contains one pre-configured rule by default:

To enable the default rule, use the off/on slider next to it. You can add more rules with the 'Add' button or delete them using the 'Delete' button. The maximum limit of instances is 30. If you wish to customize a rule, click the button that looks like a pencil next to it.

Field	Value	Description
Enable	off | on; default: off	Turns the rule on or off.
No action on data limit	off | on; default: off	Stop actions when mobile data limit is reached.
Type	Ping | Wget; default: Ping	Method used for health checking. Ping - sends ICMP requests to the specified host. Wget - retrieves the contents of the specified web server.
Action if no echo is received	Device reboot | None| Modem reboot | Restart mobile connection | (Re)register | Send SMS; default: Device reboot	Action that will be executed if there is no response after the specified amount of retries. If None is selected, only a message to syslog will be logged.

URL	url address; default: none	URL to which the wget requests will be sent (e.g., http://www.host.com).

Reboot Scheduler

The Reboot Scheduler is a function that reboots the device at a specified time interval regardless of other circumstances. It can be used as a prophylactic measure, for example, to reboot the device once at the end of every day.

You can add more rules with the 'Add' button or delete them using the 'Delete' button. The maximum limit of instances is 30. If you wish to customize a rule, click the button that looks like a pencil next to it.
