Configure Digi server console

A DIGI console will allow you to connect to the serial interface of network devices, like switches and firewalls, remotely, just as though you were connecting to them locally.

This can be really helpful for troubleshooting and managing existing multi-tenant or dedicated servers, and also for configuring new ones. However, setting up a DIGI console for the first time can be a little laborious if you’re not familiar with the process.

We've based this guide on a DIGI CM 48 but this approach should work on the rest of the Digi range.

In our opinion, the first thing you ought to do is perform a factory reset on the DIGI itself. It should be fairly obvious why, but it’ll give you a clean sheet of paper to work from. You should find a small reset button on the front of the device (see below), all you need to do is hold it down for 30 seconds.

Once that little job is out of the way, you’ll need an RJ45-to-serial adapter in order to connect to the DIGI server via the console. Now you simply connect the RJ45 to the console port on the DIGI and the serial to the computer (the image below illustrates this). If there’s no serial port on your computer, you’ll need to use a USB-to-serial connector.

After you’ve sorted out the necessary connections, you should be able to connect to the DIGI using PuTTY, or any other serial console, as illustrated below. 9600 bps is the default baud rate setting of the DIGI console by the way.

You’ll see the login screen appear once you’re successfully connected. Use ‘admin/admin’ as the login credentials to gain access, and that will take you through to the initial menu system, which is shown below.

The initial menu is navigated via numeric options, so you’ll need to first select Option 7 to get into the System Admin menu, and then Option 1 to get to the User Admin menu, which you can see below. That will allow you to change the password. Then hit ESC to go back and return to the main menu.

After changing the password, you need to change the IP on the DIGI device. The three images below show you the steps for changing the IP, subnet mask, and Gateway from the Network Configuration menu.

When you’re in the Network Configuration menu you can also update the DNS settings, as per the example below. If you don’t have your own DNS servers, Google’s DNS service is on 8.8.8.8.

Once you’ve completed those steps you need to return to the main menu, making sure you save all your changes (Option 8).

In the next screenshot you’ll see the IP details haven’t updated after changing and initially saving them. That’s because the changes have only been saved to the flash of the device and you will next need to apply them to the device for the changes to take effect.

Select Option A to apply the changes as per the example shown below.

After all those steps have been successfully completed, you can log back in using your new admin password, and you’ll see the IPs have also changed. They should look like this:

You should now be able to browse to the new IP using your web browser, and then log in to continue the setup of the device via the web GUI.
