Break sequence not working

kadshah

I just brought a 2950 off ebay. I'm trying to interupt the router boot sequence
by performing a break. I tried ctrl+break with hyperterminal that didn't work.
I also tried holding down the space key that didn't help. I tried Tera Term
with Alt+B that didn't help. Any suggestions? I'm trying to bypass the password.

Step 4 Reconnect the power cord to the switch and, within 15 seconds, press the Mode button while the System LED above port 1X is still flashing green. Continue pressing the Mode button until the System LED turns briefly amber and then solid green; then release the Mode button.

Stumbled me last week as well as id never reset a 2950.

Cheers,

worked like a charm See that's why I like to work with real equipment.

Yeh its important to practice with real world equipment.

Although sometimes the reset/default cycle is massively different per device, cisco white papers are as important as technet, juniper kb etc....use it well

Have fun Kadshah.

RE: Break sequence for routers.

I'm using a Serial->USB converter, and it didn't seem to support the break sequence to get into rommon to password reset.

The trick I used was pulling out the flash simm so that it would default into rommon.

The break key sequence is dependent on the terminal program you are using, it should work without going to the extent of removing the flash modules.

Hey bro! To add in my personal experience with it, I'm also using a usb to serial for the console cable using tera term pro as my term client. But following the instruction mentioned above (i.e. reconnecting the power while holding "mode" button) did the trick for me.

Oh but wait, you mentioned break sequence for a "router" on top of your post. Not sure what the difference is with the 2950 switch, but I'm assuming there is because I've had to recover passwords for a 3620 and a 2509 in the past 2 weeks and using alt+b worked for me with the setup I mentioned.

Well, just like Pash said, the experience you get with real equipment...

Yeah the break sequence on the switches involves the mode button.

You think its crazy on the 2900/2950's, you should try the Express 500-TT's


Talk about a piece of **** switch. You have to push the small reset button when its booting, but only after a light finishes flashing and then you have to plug a PC (has to be DHCP too) into port number one, and so on and so forth. It doesn't always work either.

Don't even get me started with the fact that there is not a console port, and when the switch is under load it tends to crap out so you can't even hardly access the GUI.........

Totally bogus if you ask me. I still am trying to figure out what Cisco was thinking with the Express series of switches.

Just to add to that:-

Standard terminal program break key sequences.

Never used an "express" switch before, are those like mini-versions of a regular catalyst switch? Personally, I think the password recovery for a PIX is pretty ridiculus.
