I would like to upload a new IOS bin file to a C4503 switch via the console port. I have tried it with ROMmon, but I don't find xmodem or copy xmodem command in the ROMmon. I use Hyperterminal on my PC for the procedure.
Is my ROMmon version not good perhaps?
When the Supervisor II-Plus, III, IV or V-equipped switch boots up or resets, there are these two possibilities:
The switch starts up normally and displays the Hostname> prompt or the default Switch> prompt.
The switch cannot find the image, the image is corrupt, no image is present in the bootflash device, or the boot variable is set incorrectly and therefore winds up in ROM monitor (ROMmon) mode. It displays the rommon> prompt. In ROMmon mode, the switch must be able to locate a valid system image from either the bootflash device or the slot0 Compact Flash card. These Supervisor Engines also provide an Ethernet Management port (10/100 Base T), which is available only from ROMmon mode and can be configured to download a new valid image through TFTP from a TFTP process. There is no option for Xmodem or Ymodem which allows you to copy an image through the console port.
