CATALYST 2820, console port config for modem


I’m a 2nd semester CCNA student, and I purchased a old CATALYST 2820 switch for training purposes. I do not know the password and the console port has been configured for a modem. I thought that it would be easy to reset the password—but cannot find any way to do it with the 2820, and the console port configured for a modem.

Does anyone know what the default factory password is? If the password has been changed (from the factory default), how can I reset the system?

Re: CATALYST 2820, console port config for modem

I appreciate your help!

I did look at that link several times—my 2820 has a mfg. date of Sept 97. I held in the Mode button, but the LED above port 1x does not come on (held it in for over a minute). I never see any info. using the console port.

I did try attaching a modem to the console port—it works—I get a login prompt. I don’t know if it is the factory default password. I know that the rollover cable is working—tried a 827-4v.

Am I doing something wrong???

Thanks, David
