Download the BIN file (any version will do fine just to get the switch operational) and transfer it to a USB stick (maximum size 16 Gb, FAT16). In ROMMON use the following command to boot the IOS from the USB thumb drive: boot usbflash0:filename.bin
Once the switch boots up normally, use the CLI to upgrade the IOS using the TAR file: archive download-sw usbflash0:IOS_filename.tar
