It seems that when all lights are on, and one of them is blinking, the corresponding port is broken. It could be the port's associated SRAM chip, or other hardware issue related to the port. It cannot be fixed with an update.It seems that when all lights are on, and one of them is blinking, the corresponding port is broken.

Using a Null-Modem Cable , hook up the Console port of the switch to an available COM port on a computer (cable must be able
to provide serial port communication between 2 computers).
Set up a Hyperterminal session to that COM port (e.g.: com1), with
the port settings at 9600/8/N/1/N (. When the screen comes
up blank with a blinking cursor, hit [enter] once or twice to bring up a
login prompt.
Alternative to 1 and 2 above, if there is a known assigned TCP/IP
address for the switch, one can telnet to that address, hit
[enter] once or twice to get the login prompt.
Default logins to try are admin/(no password) or security/security. One of those 2 should bring up the management menu.
To reset factory defaults, type SYSTEM[enter] then type
INITIALIZE[enter]. This will reset everything that has been set up on
the switch, with the exception of the TCP/IP address, if there is one.
All other previous configurations will need to be
re-entered.
You can type in username "3comcso" and password "RIP000". It will ask you to reinitialize the switch.
This will reset all settings including passwords.
I have same problem. So the solutions is (in my particular case), when you done everything as it written in the reseting instruction. You face blinking LAN/WAN ports and no any activity with Alert LED. After 30 second or even 1 min (i don't relly know do you need to wait or not), i disconnected LAN/WAN ports and connected it again without repowering. Then Alert LED starts to blink slowly every 2 second. After re-applying power it was reseted.
9 flashes should only occur if you are trying to print directly from a non-compatible digital camera. Check where your USB cable is plugged into the printer. The cable coming from the computer should go into a 'square' port in the back of the printer -- not the rectangular port on the lower right side of the front of the printer.
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
Hello Mike,
Are you able to log into the web interface of the product and see the data statistics for the ports?
This switch has a web management interface, so I'd advise logging into that to see what's actually happening to each port.
Take a look at that and get back to me with your findings. If you find that you can't access the web interface, there may be another issue we need to look at.
Let me know how you get on.
Thanks

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.
