Summary[edit | edit source]

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 TRB140 devices.

The information in this page is updated in accordance with the TRB1400_R_00.01.03 firmware version.

Ping Reboot[edit | edit source]

The Ping Reboot function periodically sends ICMP echo 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 Reboot section contains one preconfigured 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. If you wish to customize a rule, click the button that looks like a pencil next to it. Refer to the figure and table below for information Ping Reboot configuration.

Periodic Reboot[edit | edit source]

Periodic Reboot 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.

The figure below is an example of the Periodic Reboot configuration page and the table below provides information on the fields contained in that page:

Wget Reboot[edit | edit source]

Wget is a computer program that retrieves content from web servers. The Wget Reboot function works in a very similar manner to Ping Reboot. While Ping Reboot sends ping requests to determine whether the conditions for the specified action have been met, Wget Reboot attempts to retrieve the contents of a web server.

The figure below is an example of the Wget Reboot configuration page and the table below provides information on the fields contained in that page:
