I've noticed that the Cisco 2501 does not support the xmodem command(I don't have a transiever yet so I want to upgrade this way)the version I have is 11.0(10c). Does anyone know what the correct protocal is? I've been to Cisco site concerning xmodem and the 2501 is not one of the routers that use it. By the way I have 8 megs ram/8 megs flash if anyone asks :) I do have crossover cable but I don't think that would work using the aux LOL Any suggestions would be humbly appreciated. Doing the upgrade via console(which I know would be slow)doesn't bother me at all. Thanks :)
 
rather difficutlt if I don't have a transciever is it not?
 
I test and load Cisco routers all day long using a Roll-Over
console cable and the RJ45 to 9-pin adapter plugged into the
serial port on my PC running Win98. I use ProComm as my terminal emulator, Xmodem, 8,N,1,9600

Right after you power on the Router, you will see a line that starts with 2500 blah blah. This is where you press the BREAK key, which is Alt B in ProComm. (try Ctrl Break
in HyperTerm)

This will get you the > prompt.
Type o/r 0x142 <return>
Type init <return>
try &quot;reset&quot; if &quot;init&quot; does not work

You will come up to the Router> prompt where you can now
go to the Enable prompt and erase the old config in NVRAM
by typing &quot;erase start&quot; followed by &quot;copy run start&quot;

At the Router# prompt, type &quot;config term&quot;
Type &quot;config-register 0x2102&quot;

Now you can power cycle the Router and it will come up without any passwords. If you want to keep your configuration, you will have to &quot;copy start run&quot; after getting to the Enable prompt, then you need to reset your
passwords before doing a &quot;copy run start&quot; then you can reboot.

You can find several good TFTP servers that will run on your
Win98 PC. You can go to &quot; to find them.

Copy your new Cisco image into some directory on your PC,
then set the TFTP server to point to this directory for its
default. If your Router has an IP address on an Ethernet
port, you can set your PC to be in the same subnet and netmask. Once you have rebooted your PC with the new IP
address, you can use the &quot;copy tftp flash&quot; command to copy
the new image to your Cisco router.
