Catalyst 3750-X Series Switches

Hi,

Can you bring it to rommon prompt (by using the ctrl+brk) and use "boot flash:c3750e-universalk9-mz.122-58.SE2.bin"?

Make sure the image is in flah location. Else use the right image name.

Once it is up, check your start up config to see the boot command hardcoded.

HTH,

The reason why your 3750X cannot boot is because of either there's no IOS or the IOS available is corrupt.

You'll need to completely download the BIN file from Cisco and verify the MD5 hash matches with your file.

Next, get a USB stick and (hopefully it's supported), format to FAT16, copy the BIN file into the USB stick and insert the USB stick into the sole USB slot in the appliance.

In ROMmon, enter the command "boot usbflash0:IOS.BIN".
