How to factory reset Cisco 1700 Router

Hopefully I can help you here....its a very common thing to happen.


First, I take it you dont know the passwords for console access or telnet/ssh?

I will assume that these devices belong to you.

step 1. Plug a cisco console cable into a serial port on your pc
step 2. Plug other end into Cisco console port
step 3. Using hyperterm or putty or similar connect to the serial port
step 4. boot router, and make sure you clearly can see the output (this confirms you have good serial comms)
step 5. if this fails, adjust the comm port settings (9600, 8,1,n are the default)
step 6. now you have to do the only hard part...send the break command:

Break command list: Break Commands

Go down the list and match your OS and SW and try the sequence suggested.

If this fails several times do what I do: Install putty (free) and then to send a break so you can get into rommom just hit "ctrl-a b".

Yes try it again... lol... we were waiting for that!

You have steps listed....try to find a another pc to try...try to reset the bios and see if that for some reason would help. But yes, try putting it back in. If not, id say rma time.
