==Summary==

This page is an overview of the <b>Maintenance</b> section of {{{name}}} devices.

==Auto Reboot==
===Summary===
----
Various automatic device reboot scenarios can be configured in the <b>Auto Reboot</b> 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 {{{name}}} devices.

===Ping/Wget Reboot===
----
The <b>Ping/Wget Reboot</b> 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. If you wish to customize a rule, click the button that looks like a pencil next to it.

===Reboot Scheduler===
----
The <b>Reboot Scheduler</b> 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. If you wish to customize a rule, click the button that looks like a pencil next to it.
