How-to access ctrlX CORE if IP-Address is unknown/misconfigured

No connection to your ctrlX CORE anymore?

You don't know the IP address of your ctrlX CORE?
Or you (accidentally) misconfigured your IP settings?

You can always connect to the ctrlX CORE via the unique IPv6 Link-local address.

But how to figure it out, and how to use it?

1. Check the Typ Plate of your ctrlX CORE for the Mac address of the XF10 interface

   

2. To calculate the IPv6 Link-local address from this you can either do it "by hand", there is a nice guide from Lenovo

   Or you use one of various online calculators, like this MAC to IPv6 Converter

   

3. Use this address but it in square brackets[] and add https:// in front, like:

   https://[fe80::260:34ff:fe8b:7f7a]

This works only for the interface specified on the type plate.

Make sure IPv6 is activated for your network card.
