Connection drops after replacing 3Com hub w/ Cisco 2950 1

[markgramlich]

Background:
This is a small non-profit. We have been slowly replacing our old 3Com dual speed 10/100 hubs (3C16611) with Cisco 2950 10/100 switches (WS-C2950-12). Most of these have been pretty uneventful. However, one building has had a lot of problems. With the old 3Com hub, the users would get connected in the morning and stay connected all day long. No connection drops during the day. However, when the Cisco 2950 got swapped in, the connection drops started. The drops seem to happen at almost any time of the day or night. It would take a minute or more for the connection to come back up. The drops cause MS Outlook problems and problems with an in house MS Access application. I checked and tested the cables. I moved the users to different ports on the switch. I configured the users systems 10/100/1000 interface from auto negotiate to 100FD and 100HD. Nothing seemed to help. When I put the 3Com hub back in the connection drops went away. I'm at a loss and open for suggestions.

I imagine going from his first post in this thread that he meant 2950.
