Hello,
I was handed two SGE2000 24-port 10/100/1000 switches. The default IP address does not work on either of them. Short of doing a hardware reset, is there an IP discovery utility that I can run.
If no utility, any suggestions how I can find the IP?
Thanks.
Solved! Go to Solution.

Connect a PC with Wireshark on it and look at the packet captures?
I'm not really familiar with this kind of switch - but have you tried plugging into the console port and examining the configuration? The documentation on Cisco's web site indicates it's got a console port, so try plugging a serial terminal into it and see what you get. Documentation indicates that, unlike most Cisco switches, the console port on this runs at 115200/8n1 with no flow control instead of the usual 9600/8n1.
Cheers.

Please disregard my last post. Figured it out. I was trying to use a different serial cable. The one I used that worked must have come with the switch. Looking back on the days using serial cables there were a lot of variables with serial pin outs. Works fine with the first cable I used.
Thanks anyway.
Cisco switches and routers use a proprietary cable for the console port - a normal serial cable usually won't work.
Which is why they include one with every switch/router - so if you do a large scale deployment, you end up with dozens fo the things. :-)
Glad to help. Please mark your question answered so future people looking for something similar will know they can look here!

Thanks much Darren! I tried the console port yesterday, but at 9600/8n1 Hardware. 115200/8n1 no flow control did the trick.
Much appreciate the tip.
Regards.

Since that worked on a non production switch I want to do the same on one that is in production - don't have the IP for it either. On the non production switch, I powered it up after setting up hyper terminal and everything scrolled by and I was able to log in.
For the production switch, in hyper terminal do you how to get it's attention to log in? Using the same parmeters. Been so long since I used hyper terminal. Tried enter twice, ctrl enter, etc.
Thanks for any advise.
