In order to get the access to IPMI, you need to access the Client Area and go to the Services – My services and hit the button “Manage Product” next to the server you want.
On the new page, click on IPMI, enter your IP-address (you can see it on https://whatismyipaddress.com/) and click submit. This will create a request for Java Applet formation.
If the data was entered correctly, you will see a corresponding notification. Next you need to click a button Download Java Applet.
Afterwards, you need to save and launch the downloaded file.
