catalyst 3500

[kjacks]

I have several catalyst 3500 XL (3512) switches that are going down and ports 3, 7, and 11 light up amber. I try to console in with a laptop and can't get a response. Any suggestions on how to fix this?

Hello,

try to reboot the switch with the laptop consoled in, and check if there are any POST failures. Possibly you are experiencing a hardware failure. How old are the switches ?

Thanks for your reply.

I've tried rebooting with a laptop consoled in and all I get is either a tilde (~) or a capital c (C) show on the console.

The switch shows ports 3, 7, and 11 in amber and the RPS is amber also, but I don't have it connected to any external RPS.

These are 5 years old.

Thanks for any help.

Can you confirm that your terminal emulation program is configured for 9600-8-N-1 ? If it is, try and configure it for the next higher speed (19200) and then try again. Repeat the process till you get to a baud rate of 115200. Maybe the console has been configured for a non-9600 baud rate...

What are those ports connected to, if anything?

When you say they are going up and down, do you mean the port or the switches?

[kjacks]

Two of the ports connected to a PC and one had nothing connected. I've disconnected everything and no luck.

What I mean is that I have several 3512 switches (6) and I've had three just stop working and not responding. One I was able to console into, but I couldn't reload the IOS. This one doesn't respond at all except sometimes when I plug it back in I get a tilde(~) or a C.

Are these switches that you've set up? I mean, could someone have changed the con settings?

You can always break the process by holding down the mode button while powering it up.

Yes they are ones I set up. I tried a console connection all different ways and no luck. I also have tried holding down the mode button and nothing. I think it is dead.
