Hello again,
You don't need open ssh for system information, look at the https://servername:2381 and make a screenshot of the page once you hase loged in with admin rights. You should see the model. If the page also shown unknown, the managrment agents are not running or the credentials for SNMP or WBEM are incorrect. So if you coild attach a screenshot of the logged-in System Managed Homepage and a complete log of the identify of a server wich is an unknown type.
That would realy help.
