I got 2 Catalyst 2950 switches from my work so i was planning selling them.  I tried to update them to that latest software from the cisco.com site.  After updating them using the directions on there site they booted just fine.  I try to use the Express Setup by holding down the mode button and that works just fine but when i pull up the website 10.0.0.1 address from the computer connect to vlan1 it just shows a blank page.  I have no idea why the page wont come up but I can telnet just fine.  Any ideas?

I would make sure that the firmware that you downloaded had the web interface feature part of that firmware, it is available with and without the web interface.

Sorry if that was a dumb statement, I try not to assume anything.

did you run the upgrade via the console cable?  Did the upgrade show any errors?

did you run a 'write erase' and delete the vlan.dat file?

after that were you prompted to run the initial setup and follow the prompts?

Also, on a side note.  I would assume (big assumption) that anyone who buys a Cisco switch.  The first thing they would do is put the firmware rev that their environment calls for and config it as they wish.

The only thing they will look for is bad ports or DOA.

Just my additional two cents.

Thanks for the heads up on how must people buy cisco switches.  I wont attempt to update the other one.  I upgraded via vlan1 over telnet with tftp.  I did not do "write erase", is that something i should have?  No i didn't see any error messages.


Here is what i followed.  All but the "wr mem" said shut down down ... (I don't remember the rest)

After that I held the mode button to reset then tried to go to express setup.

If you have a Cisco console cable, that is the way I would recommend.  With the console cable you can actually watch the device boot up.  It is more informative that connecting via TCP in my book (though I am no Cisco expert... yet!)

Good luck!

At that point press enter, it will then ask "Would you like to enter the initial configuration dialog? [yes/no]: type y or yes

and follow the prompts.

You will give it a name and an IP address, then you can attempt to connect to the http interface

I would run

write erase
delete flash:vlan.dat
and then reload without saving or running a write memory.

Then run the initial configuration setup.

Thats what works for me.

Perfect that worked.  After setting up the ip address it loaded.  Any idea why it wont load into the Express Setup without setting up the ip address like before i updated it worked that way.

I don't know, as I don't do it that way.  I would think because it doesn't have an IP but I'm not certain without hands on lab to test. Sorry.

Glad you got it worked out.
