You may come across this issue if you have the “HP System Homepage” configured on your server. Basically when you open the system homepage you expect to see NIC, Power, System, Processor , temperature information etc.
However you are seeing no information and the System Model is showing as unknown.
We came across this issue to the resolution for this was to change the security settings of the SNMP Service to the same as the below screenshot.
Public – Read Only
You do this by going into the properties of the SNMP Service and going to the security tab and simply adding the name in.
Once you have edited the security settings you will need to restart the SNMP service and your homepage should be working for you.
