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.

Sounds like they are daisy chained together and this glicth locked the system.  How are the switches routed through your network.  Do you connect via T1 or Fiber?

SOURCE: Problem with SW 4400 - restarting....

switch dont restart by themselves without command, first remove the switch from the network, disconnect from internet, make sure you hadn't fired anybody recently it sounds like a hack. reduce network traffic to local area only and priortise important internet traffic. now got back to the switch and troubleshoot make to check the reboot command on error or when error is found, if the problem stops when the switch is remove somebody is messing with the network.or the darn switch is faulty install a new one.

I have a old dell and the yellow light stays on, what's wrong?


A steady or Amber (Yellow) blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

Dell dimension 5100 ethernet port flashing orange


If the port works, it should be steady yellow. Flashing means that your Ethernet circuit on your motherboard has a problem.

You will need to have the motherboard reflowed. The processors have probably come unseated from overheating.
