Re: 3com 3300 TM - all Ethernet port not working, power...
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.

1 Remove power from the Gateway.
2 Disconnect all your computers and the cable/DSL modem from the Gateway router.
3 Using a straight through Ethernet cable, connect the Ethernet Cable/DSL port on the rear of the Gateway to any one of the LAN ports.
4 Re-apply power to the Gateway. The Alert LED will flash as the Gateway starts up, and after approximately 30 seconds will start to flash more slowly (typically 2 seconds on, 2 seconds off). Once the Alert LED has started to flash slowly, remove power from the Gateway.
5 Remove the cable connecting the Cable/DSL port to the LAN port, and reconnect one of your computers to one of the Gateway LAN ports.
6 Re-apply power to the Gateway, and when the start-up sequence has completed, browse to:
and run the configuration wizard. You may need to restart your computer before you attempt this.
7 When the configuration wizard has completed, you may reconnect your network as it was before
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
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
You can type in username "3comcso" and password "RIP000". It will ask you to reinitialize the switch.
This will reset all settings including passwords.
Well I think the port is bad, I had one that did something similar to your problem. I got on the 3Com website and submitted and RMA request and they upgraded my with the newest model. But if yours is still in stock they will replace with the same type. That is what I would do. Hope this helps ya.
your SPA2102-R seems to have one ethernet connection and one internet connection.
your WRT54G-TM seems to have one internet connection and 4 ethernet connections.
What you are trying to achive is; plug a ethernet cable into the ethernet connection on your SPA2102-R then plug the other end into the internet port of the WRT54G-TM
hope this helps, I have assumed that you intend to use a DSL broadband supplier not ADSL.
if you are changing service from DSL to ADSL then your WRT54G-TM needs to be first in line configured and working. then plug the internet port from the SPA2102-R into any of the WRT54G-TM ethernet ports.
