I was given an HP Procurve 2824 j4903a and when I connect it up to my Ubiquiti UDM SE I don’t see an IP or anything opaque appear on my network.

Do I need to use what looks like a COM/serial port on the front of the device to access its configuration? It says web browser on the above link so I assumed it had a web UI.
