Requirements
- Have your .bin file stored locally (laptop)
- linux + minicom with working serial connection
Steps
- Connect to switch - minicom 9600 8N1
- CHANGE baud rate of switch (otherwise it will be hours to load a file)
- change minicom to 115200 8N1
- ready switch to recieve file over xmodem
- send the local .bin file with minicom through xmodem
LAN Product Support
- watch your .bin file load! It will still be slow, but not hours @ 9600
- set baud rate back to 9600
- otherwise you or someone else will be really confused when they next try to use it. Go back into the bootloader by power-cycling the switch and holding down the “Mode” button.
- type boot (may have to type boot flash:/<your cisco file>.bin
- Check that you can reboot OK without ending up in the bootloader again.
Other Tricks
- If the switch is not going into the bootloader, you may be able to force it
- Try power-cycling the Catalyst while holding the “Mode” button on the front in to get the bootloader.
- file system needs to be initialzied
- Type “flash_init” to initialise the filesystem. (In our case, this wasn’t necessary)
- Type “load_helper” to load any helper files (in our case there weren’t any since we’d just wiped the flash).
