If you can get into the console now, I would HIGHLY recommend putting an address on it for management, and then transfer the image via tftp. Xmodem is painfully slow.

Sateesh,
Here is a set of instructions I wrote a while back. There is a way to speed up the transfer time using xmodem. It will take minutes instead of hours.
How to Speed Up Xmodem Recovery
When a user tries to recover the switch from a corrupted or missing IOS,
the copy xmodem: flash:[IOS filename] command might not be displayed under the switch: prompt.
The copy command might be displayed under the switch: prompt, but not the copy xmodem: command.
Complete these steps in order to speed up the Xmodem recovery:
Set the baud rate to 115200 on the switch: prompt.
switch: set BAUD 115200
!--- The screen goes blank after you enter this command.
Restart HyperTerminal.
Under COM PORT properties, select the bits per second as 115200. The switch: prompt is displayed.
Start the Xmodem recovery.
After the Xmodem recovery, set the BAUD rate back to 9600. If the set BAUD 9600 command does not bring the baud rate to 9600, issue the unset BAUD command in order to bring the baud rate to a default value of 9600 bps.
HTH,

I would make a backup of your current .bin file, and then delete it from flash. Then upload the new one, and reboot the switch.

Sateesh,
It would be cutting it close but there are a few unnecessary files in flash and might be able to get new IOS on there. Also you could delete the existing IOS and then TFTP the new one which is a little risky.
I believe these are the web GUI files and if you are not using these you can remove them.

html
info.ver

Yes. You don't need those files to operate.

Yes, you can remove it if you are not using it.
