SOURCE: 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.

SOURCE: Link and activity lights on 3Com Switch ports without connection

Do the ports work when the cables are connect?  I did some re-search and this seems to be an ongoing issue with 3com switches.  It should not effect the use of the switch

1 Answer

I have a 3com 4500 connected to 2 5500s (A & B), which are the the GWs for the 4500. I issued on the 4500: ip route-static 0.0.0.0 0 192.168.0.254 preference 60 (5500 A) ip route-static 0.0.0.0 0...


From your scenario what i guess is the two 5500's (A&B) are connected to each other also. Thats why the link between B&4500 is remaining down due to STP ( to avoid Network loop).
Please correct me if I am wrong.


What is the status of the link connecting 4500 to 5500 B when 500A is active and when 5500A is down .

If you are running STP i will suggest you to wait for 2 minutes after 5500A goes down and STP will be recalculated and the link connecting to 5500B will become active and then the route will also become active.

Best regards

How can configure trunk


not sure about the 3COM side, but on the Cisco side... go to the configure prompt, then the port that you need to trunk (int [interface name and number] and enter)

Once you are in the interface, use the following command:
switchport trunk encap dot1q
switchport mode trunk

Then make sure that the interface is not shut down, connect the switches together and (hopefully) the 3COM will negotiate to trunking... if not you will need to manually configure the 3com.

Hope that this helps!

I cann't connect to my switch


The primary connection method for those switches would be serial connection. In the box there should have been a DB9 serial to RJ45 cable. Hyperterminal default settings would allow you to connect.
