Catalyst 3560-CX-12PD-S does not enter express mode

[JarnoValkonen38927]

Hi!

I have purchased used 3560-CX and I´m trying to enter express mode to start configuration of particular switch. Problem is that when I hold down mode button about three seconds, all light`s (texts) turn green and then I release it. It seems to start POST again, which is wierd, because getting started manual does not say so. After POST I connect cat cable and wait for my computer to get IP-address from switch. That never happens. Then I tried to reset the switch and enter express mode again. Futile thing, cause things are going same way again. Any ideas what I`m doing wrong?

ps. I cannot find getting started guide for this switch anywhere, so I´m assuming that getting started for Catalyst 3560 is the same for 3560-CX series. Or 3560-X is same for 3560-CX series.

Hi,

Try using this guide, if not, you can log in to the CLI and erase the config and restart the switch.
