Summary

This chapter is an overview on various recovery options for a {{{name}}} device.

Default login information

Using recovery methods resets the device's configuration to its default state. Therefore, you will need to use the default authentication info in order to login to the device. The default login information for {{{name}}} is provided below:

• Default Address (LAN IP): 192.168.1.2
• Default Username: admin
• Default Password: admin01 or random generated password*

Devices with random password

---

* Certain devices or batches of a device may have a generated password out of the box, instead of admin01. For {{{name}}} devices, batch from when unique passwords are used is

You can find the batch of your device on the [[{{{name}}} Product Labels|Product Labels]] sticker.

Factory reset

A factory reset returns the device back to its default factory settings, i.e., it deletes all custom configurations. Below you will find various methods of performing a factory reset on {{{name}}}.

Reset Button

---

The reset button is located on the {{{panel}}} of the device:

[[File:{{{file_reset_button}}}|{{{size_reset_button}}}px]]

The reset button has two functions:

• Reboot the device. If the reset button is pressed for up to 4 seconds, the device will reboot. Start of the reboot will be indicated by the flashing of all Ethernet LEDs together with SFP LEDs.
• Factory reset. If the reset button is pressed for at least 5 seconds (by default), the device will perform a factory reset and reboot. Ethernet/SFP LEDs indicate the elapsed time while holding the reset button. When all LEDs light up, it indicates that 5 seconds have passed and the reset button can be released. Start of the factory reset will be indicated by flashing of all Ethernet/SFP LEDs.
  NOTE: the default button hold time value (5 seconds) can be changed in the switch WebUI, from the System → Administration → [[{{{name}}}_Administration#General|General]] page.

WebUI

---

You can also perform a factory reset from the router's WebUI. To do so, login to the router and go to the Backup section found under the System tab (System → Maintenance → [[{{{name}}}_Maintenance#Restore_default_settings|Restore default settings]]). In the very bottom of the page there's a Restore button that performs a factory reset on click:

Command line

---

You can perform a factory reset via command line by executing the firstboot command. After this you will be asked to confirm the reset. If you're sure, type the letter y and press "Enter" or type the letter n if you wish to cancel the reset.

If you agreed to perform a factory reset, next type in reboot and press "Enter". The switch will be reset to it's factory settings and rebooted. The entire sequence of events should look like this:

root@Teltonika-{{{name}}}:~# firstboot
This will erase all settings and remove any installed packages. Are you sure? [N/y]
y
/dev/mtdblock5 is mounted as /overlay, only erasing files
root@Teltonika-{{{name}}}:~# reboot

You can find more information on the command line interface (CLI) [[{{{name}}} Maintenance|here]].

Bootloader menu

The bootloader menu is a special router state used as a recovery tool in case the router becomes inaccessible even after a factory reset. It can be used to upgrade the router's firmware or bootloader version.

In order to place the router into the bootloader menu state, follow these steps:

• Plug Ethernet cable from your computer to {{{name}}} Ethernet port.
• Press and hold the reset button.
• While holding the reset button, plug the power cable into the router. Continue holding the button for another 5 seconds.
• Release the reset button.
• The LEDs will begin to blink rapidly, indicating that the device has entered bootloader mode.

If you followed all the steps correctly, all panel LEDs should light up. This means that the device is in the bootloader menu state. If that is not the case, repeat the steps again.

Regardless of what the router's IP address was before, the IP address of the router when it's in the bootloader menu state is always 192.168.1.1. So in order to reach the router, you'll have to set up a static IP address that's in the 192.168.1.0/24 network (for instance, 192.168.1.2) on your computer. Instructions are provided in the links below:

• Windows
• Linux

When set your computer's IP, you should be able to reach the router's HTTP server. The address for the upgrade is:

• Firmware upgrade URL: 192.168.1.1/index.html

Type in the relevant address into the URL field of your web browser, upload the image file and click the Update button. Firmware image files can be downloaded from [[{{{name}}}_Firmware_Downloads|here]].

If everything was done correctly, the update should begin. At this point you can close the browser window. The update will take about 120 seconds.

Additional note: don't forget to restore your computer's IP address settings.

RMA

If conventional recovery methods do not help, you may need to send the device to warranty for repair. The warranty process is described here.
