3COM 3300 Keeps power off. Its it faulty?

[powersl]

I have a 24 port 3COM 3300 (3C16980) which keeps powering off intermittently. The longest I've had it running is 1 hour. Generally it keeps powering off after 2 mins or so. I guess it must be an overheating problem but can't seem to find any hot components inside.

I was going to fit a 3com 1100 PSU to see if that could fix it but the wiring is slightly different.

Any ideas or has anyone else had this problem.

Thanks

Don't open the unit! send it back to 3com it has a limited lifetime war.

Are you serious? I have a 3300 that keeps freezing up... I'd pay the shipping back to 3COM if they will repair it!

I have had the same problem. 3Com used three different vendors for their power supplies. One is more prone to
failing than the others. You might be able to purchase
a replacement P/S from

if they have
any.

The 3300s also have problems when you have mixed firmware in your stacks. I had a problem using 2.60/2.61/2.69 amongst the switches. Units would stop forwarding traffic or reboot without warning. The only easy fix was a power cycle. After updating all of my 3300s to 2.70 I have had no issues. (Knock on wood!)

BTW, I have also returned several devices to 3Com with no hassle getting a replacement.
