switch problem

I have an old 1924 switch. I am trying to gain access to it through the console and telnet. Through cdp on a switch attached it I see it has the ip We had another switch with the same IP, but have since changed it when we saw the duplicate. I get nothing through the console port when connected. It is a serial console on this switch. It was made is 1997 I believe. Is there anyway to gain access? It won't connect through telnet. Is there a certain cable I need to get in through the serial console?

Re: switch problem

There are 2 models of 1900s. The original edition which uses a NULL Modem cable and the standard/enterprise edition which use a ROLLOVER cable. Via CDP output check the software. If it is 5.x, it is the original edition, 6.x or higher is standard/enterprise.
