3C16988A 3300MM - default IP - basic question

[ircaddict]

Hi, is the 3C16988A set to DHCP client mode after a reset?

I have just purchased a second hand unit and i am trying to give it an ip. Or does this sort of thing have to be done through the console port?

cheers

Hi - connected it up via the console port and assigned it an ip sorted.

3300s are only in DHCP if from the factory or the IP interface is reset (from telnet or console).

The "factory default" option does just that EXCEPT for the IP.

I have the same problem, I bought the switch second hand over the summer and it's been working, except i can't manage it.
My laptop doesnt' have a serial port so i can't console into it.
I have a Cisco console cable, would that work as it has RJ-45 on one end and seriel on the other?

I'd like to get this switch manageable.

Thanks!

Hi - a cisco console cable will not work. It is wired up different from a normal null modem serial cable for starters. I have a usb - serial convertor. I will see if i can get this to work with the null modem cable i made up. Will reply soon.

Hi Beholder - I have managed to use a usb-serial convertor (costs around $15 - $20 - try ebay.com) successfully to connect. Once you have connected to the serial port (9600, n, 8, 1) it is fairly straightforward to set IP. see screen capture of session below. to reset back to factory default which doesnt reset the ip but resets password if one has been set try login 3comcso password RIP000 or login recover password recover. If these don't work. send a post
