How to Manually Reboot or Reset a Switch


The Reboot feature of the network device is useful when certain changes in the settings require a reboot to completely apply the configuration settings, or if the device is not functioning as expected. The configuration settings of the network device get reflected after the device restarts.

The Reset feature is used to remove the running or current configuration settings on the network device and restore it to the original default settings. Manual reset is recommended when the whole device needs to be reconfigured, or in case you forget the password and not able to recover by any means such as accessing the console using Telnet or Command Line Interface (CLI).

This article provides instructions on how to manually reboot or reset your switch.

Manually Reboot the Switch

Important: When a switch is rebooted, the running configuration file is deleted. Before proceeding with the reboot instructions, make sure to save all the running configuration settings to avoid data loss.

Step 1. Log in to the web-based utility of the switch and choose Administration > Reboot.

Step 2. In the Reboot area, click the radio button that corresponds to the desired time at which the switch reboots.

The options are:

  • Immediate — Switch reboots immediately once Reboot is clicked.

  • Date — Switch reboots on the configured date and time. Choose the month and date on which you want the switch to be rebooted and the specific time on that particular day to reboot the switch.

  • In — Switch reboots after the configured time has passed. Choose the number of days and hours the switch waits to reboot. Once that fixed time passes, the switch reboots.

Step 3. (Optional) Check the Restore to Factory Defaults check box to reboot the switch to the factory default configuration.

Step 4. (Optional) Check the Clear Startup Configuration File check box to clear the configuration on the switch after reboot.

Step 5. Click Reboot to reboot the switch.

Note: In this example, Immediate is chosen and Restore to Factory Defaults is checked.

Note: DHCP Auto Configuration is enabled by default in the factory settings. In order to properly reboot the switch to factory defaults, you need to disable the DHCP Auto Configuration so the switch does not automatically download a configuration from a local server.
