Wont reset and has erratic blinking lights. Tried power reset, reset button, etc.


Does the power light blinks when you press the reset button?
If power light is blinking continuously then I think your router is not working and you need a new one.

Turn it off for 15 minutes and unplug it from the wall as well. It resets this way. Cisco Systems does have a problem with these and the only hope is to disconnect them for awhile to operate correctly again. After they are about 8 months old they tend to do this all the time

Most of the CISCO 1800 series have some ACL's configured by default.

You may want to run a show run from the CLI to make sure that there isn't one interfering.

Also from the CLI, see if you can debug port forwarding. I can't remember the command off the top of my head but I will look it up and post it for you.

''!!! WARNING: The switch is not usable !!!''


Unfortunately the show stack isn't showing any results other than it is either a hardware or software fault. I am guessing it is a fault with the hardware as the show version in your first post states "interface Ethernet-controller 4 failed POST POST error status : general error occured".

Ethernet-controller 4 is one if the gigabit ports (poss fibre port), so if you have anything attached to those, disconnect and reboot the switch and see what happens. If that doesn't work, you could try reinstalling the IOS, but at a guess I would say its a hardware fault.

The Cisco 2960 has a life time warranty. Contact the seller and they should be able to get the switch exchanged at no cost.
