You will then be displayed a message asking you to initialise the data medium. Confirm this dialogue box and wait for device startup to be resumed and for the status screen to then be displayed.

Once the device has been started up, you will see the status screen on the local console.

This screen will show you general status information and the most important configuration options of your device.

1. Network and access configuration via console

From the status screen, you can get to the configuration menu by pressing the key <F1>.

For starting up the device, you now need to set the network configuration and specify the device password.

1.1. Network configuration

Use this dialogue box to set up the network configuration of the device. The IP-address, netmask and the optional default gateway will be queried.

In most cases, the device will need to also access network devices outside of its own network segment. The default gateway must also be configured for this purpose.

Once these values have been entered, the configuration will be activated, meaning the device will be immediately reachable via the network and at the entered IP address. One way of testing this is to send a ping from another device in the network.

1.2. Access to the web interface

A large part of the device’s configuration is carried out via the web interface. Access to this web interface is protected by a password, the device password, which you need to specify first.

The factory settings do not include a device password, meaning you cannot yet access the web interface. Press the key <F1> on the status screen and select device password in order to set the password.

Then select the option web interface from the configuration menu to activate the web interface.

Once you have completed these steps you will see the configured IP address in the box device information and web interface: on in the access box on the status screen of the console, as shown in the screenshot above. If you have already correctly connected the device with your network, you will now see that the network connection is active (Network: ACTIVE in the Status box).

1.3. Protecting access to the console

After the basic configuration, access to the local console is not protected. This means that anyone who has direct access to the console (e.g. through access to the server room, or in the case of Checkmk virt1, through access to the management interface of the virtualisation solution), is able to change the basic configuration of the device.

In order to protect such access, you have the option to activate a login that must be used in conjunction with the device password before settings can be made or the current status viewed.

If you have already activated the web interface, you will have already set a device password and do not need to assign a new one. If you have not done so, open the configuration menu on the console by pressing the key <F1> and select device password to set the password.

Then select console login from the configuration menu in order to activate this option.

Once you have completed these steps, you will see console login: on in the access box on the status screen of the console, as shown in the screenshot above.

2. Basic settings on the web interface

Having enabled access to the web interface through the configuration you performed previously, you can now open the web interface over a web browser on a computer that is connected with the device via the network. For this purpose, enter the URL http://<ipaddress>/ for the device (in this case into the address bar of the browser. You will now see the login screen of the web interface.

After you have logged in with the password previously specified for the web interface, the main menu will open. From here, you can get to all features of the web interface.

On this menu, select the item device settings. In this dialogue box you can see and change the most important device settings.

By clicking on the titles of the settings, you will be taken to the dialogue box for adjusting the respective setting.

If you have DNS servers available in your environment, you should now configure one or more of these first so that the resolution of host names can be used. If you have one or more NTP servers for time synchronisation available in your environment, enter these as IP addresses or hostnames under the item NTP server.

If emails are to be sent from your device, such as notifications in the event of problems being detected, you must configure the option Outgoing emails. To do this, enter the SMTP relay server responsible for this device and any access data required. All emails generated on the device will be sent to this server. Under this setting, you can also configure all emails generated by the operating system of the device (e.g. in the case of critical errors) to be sent to a particular email address.

The basic configuration of the device is now complete and you can continue setting up the first monitoring instance.
