Well I just got a HP Procurve 2312 switch, but having problem to configure it, it says that it is manageable but I can't see how, the manual in the HP web site is not that helpful has the features showed there are not available in the actual switch, therefore can't do much.
First, connect your computer to the switch.
Lastly, enter the switch's IP address. This is typically 192.168.0.1, but check with your manual to be sure.
If everything goes well, you'll see the HP interface in your browser.
