Network Switch "locks up"

I have a 3Com 2250 Baseline Plus switch that is giving me headaches. It seems that after a period of time, all ports that are not in use simply "freeze" and if you try to plug in a new device, you need to reset the switch first. I have called 3Com and they have sent a replacement switch. I have also upgraded firmware etc...

Here is another item to note. I just bought this switch about 6 months ago because the old one was freezing completely - I mean the switch would just lock up altogether and you would be forced to reboot. At least now, it keeps running and you only have to reboot when you plug in a new device.

Does anyone have any recommendations as to what I should look for? I have read various articles about "broadcast storms" and network traffic overloads, but aside from buying some expensive piece of network analyzer software, I wouldn't have any idea where to start troubleshooting.

I have a single Dell Poweredge server plugged directly into one of the gigabit ports. I have a Proxim 600AP (Access point) and various HP, IBM and Dell client computers all running Windows 2000 or Windows XP. I also have 3 printers using HP Jet Direct card. Internet access is a Westell modem/router unit supplied by Verizon.

Thanks in advance,

Jerry

Sounds like you have either another bad switch or a looming power problem.

Is the switch on its own circuit or is it being shared by many devices.

In all honesty, I don't know about the circuit. This is actually at a client I do some IT work for. I believe they have this unit plugged into a rack mount power strip that has several devices on it. Would you suggest moving that to a UPS or directly inot a wall socket?

Are power issues the most common cause of issues like these?

Q1... YES move the unit and place it on a UPS.  If the gear is not already on a UPS, it would be prudent to suggest that to your client.
Q2... YES..definitely...the only problem(s) that would be incurred on the switch are defects, bad firmware updates, and power.
