3Com SuperStack 3 3300 TM Networking Switch Questions & Answers
Doesn't POST
I've got a Superstack II 3300 24port switch, all leds are on, and led 8 blinks.
I'll let you know if I find a solution.
3com 3300 TM - all Ethernet port not working, power led flashing
A blinking power LED means that the switch is either downloading software, or is initializing which also includes running the Power On Self Test. You may have firmware issues with the switch and/or the switch is stuck in initialization mode. You may have to contact 3com regarding a warranty issue.
Hope this helps. Good luck.
How to check if the switch is manage or unmanaged
Managed switches you can enter the default ip into a web browser, login and "manage" settings" this default IP will be vendor specific. Unmanaged you just plug in devices and that's about it. Managed switches you will pay a lot more for. Some lower end ones maybe several hundred dollars and up. If you are buying switches at Best Buy they are almost all unmanaged.

HI,
I have two 3com
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!
