OTD500 Maintenance

The information in this page is updated in accordance with firmware version OTD500_R_00.07.11.3.

Summary

This page is an overview of the Maintenance section of OTD500 devices.

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 OTD500 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.

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:

Field	Value	Description

Backup

Summary

The Backup page is used to generate configuration backup files or upload existing ones to the device. This chapter is an overview of the Backup page in OTD500 devices.

Create backup

The Backup configuration section is used to generate and download a file which stores the current device configuration. The backup file can later be uploaded to the same device or another device of the same type (product codes must match).

This section contains MD5, SHA256 checksum fields generated from latest downloaded backup file, 'Encrypt' option and the 'Download' button to generate and download the device configuration backup file.

Important notes:

1. Password field is required if Encrypt is turned on and that's when the field appears. Password that will be used to encrypt Backup file. It will have to be provided when extracting formatted zip archive to gain access to a tar file.

2. Backup file stores PIN code configured in OTD500 Mobile page, but it will only be restored if device does not have PIN code already set when backup file is uploaded - PIN code from backup file will be set only if device does not have one set already.

3. If the device does not have an Internet connection when a Backup file is being loaded, it will not reinstall software packages installed from Package Manager. You can add the package installation files to the Backup file manually, a OTD500 device will automatically install them when you load the Backup file even without a data connection.

To embed a Backup file with package installation files, follow these steps:

• Download the necessary software package installation files from here
• Download a Backup file.
• Open the Backup file and create a new folder called backup_packages in the /etc directory.
• Add the necessary package files to /etc/backup_packages
• Make sure files in /etc/backup_packages are fully extracted with the *.ipk extensions

Upload backup

The Restore configuration section is used to upload a configuration file that was taken from this device or another device of the same type.

Turn on 'Encrypted' if backup file was previously encrypted and click the 'Browse' button to select a backup file from your computer and click the 'Upload archive' button to apply the selected configuration on to this device.

Important notes:

• Password will be used when extracting formatted 7z or zip archive to gain access to a tar file.
• Backup files can be uploaded only if they are taken from an identical device (identical Product code (can be checked in the Status → System page)) with identical or older firmware.
• It is important to remember that the backup file not only changes the device configuration, but also the password. If you are unsure of the backup file's password, you may want to reconsider uploading it because you may lose access to device.

Backup Security Check

---

After uploading a backup file your device will calculate checksums for uploaded file and display them. If this backup file was the latest downloaded in your device then you can compare these checksums with the ones in your Create backup section to verify backup's integrity.

If everything is in order click Proceed to restore configuration to backup.

Troubleshoot

Logging Settings

---

The Logging Settings section is used to configure how and where the device stores system log data. The system log is a file that contains information on various system related events and is useful to engineers for troubleshooting the device.

Speed Test

Introduction

The Speed Test page provides with the possibility to test the data transfer speed of your WAN connection. This manual page provides an overview of the Speed Test windows in OTD500 devices.

Important note: speed tests can drain a significant amount of data. Therefore, please make according considerations before using the speed test tool, especially if your data plan includes data limiting.

Note: Speed Test is additional software that can be installed from the System → Package Manager page.

Speed Test

This network traffic speed speedometer will let you know what is your download and upload speed in Mbps.

Change Server

---

The speed test works by sending and downloading data from a public server and calculating the data transfer speed over a period of time. Usually the nearest server is selected automatically, but you can use the 'Change Server' button open to open a list of list of servers to choose from. This is optional, but using different servers may provide different results.

---

Once you choose a server you should see the server's service provider name appear and the IP of the server next to it. You can start the speed test by clicking the 'Start Speed Test' button.
