Depending on the mode the phone is in, it may be only a layer 2 device - meaning it just broadcasts at layer 2 to find the NBX and once discovered, uses layer 2 for all communication.

I would recommend starting with what is simple.
Have you tried replacing the Ethernet patch cord that the phone is connected to?
How about the curly cord between the phone and handset?
Does the phone do the same thing if you connect it to a different port?
Does a different phone do the same then when connected where this phone is connected?

Well I think the port is bad, I had one that did something similar to your problem. I got on the 3Com website and submitted and RMA request and they upgraded my with the newest model. But if yours is still in stock they will replace with the same type. That is what I would do. Hope this helps ya.

If you get a 'Limited connectivity" on you wirelessconnection on your laptop, it means that the wireless card on your laptopprobably did not get an IP address from the wireless router.
To fix this problem, right click on the wireless icon on the Task bar and thenclick Repair.
This will force the wireless router to issue a IP address to the wireless cardon the laptop.

Don't let the switch name fool you, HP calls it the HP 1910.
HP 1910 48G Switch Fixed Port Web Managed Ethernet Switches HP JE009A ABA
Technical Notes:
"The HP 1910-48G Switch (JE009A) was formerly sold as the 3Com Baseline Plus 2952 (3CRBSG5293) and may ship with this product labeling.SFP ports and copper ports work simultaneously, independent of each other to give a total of 52 Gigabit-capable ports."

I don't know anything about these units, nor do I have time to source any docs for you, but maybe you can try connecting a PC directly to the port your patch panel is connecting the the switch from, you can at least see if that port is working.
My next and only other suggestion is to invest in a "LAN cable tester". In my area, you can find cheap ones for U$20.
The tester will allow you to check connectivity between any two ports, and allows you to test both patch links and individual CAT5/6 cables.
Good luck!
