rommon recovery of 3750-x switch

3750-x switch is having an advanced feature for rommon recovery. for other switches we used to do xmodem recovery. for 3750-x switch we do not have to waste time like that.

follow the procedure, we can set the ipaddress even in the rommon prompt and transfer the image

Step 1 Connect your PC to the switch Ethernet management port.

Step 2 Unplug the switch power cord.

Step 3 Press the Mode button, and at the same time, reconnect the power cord to the switch.

You can release the Mode button a second or two after the LED above port 1 goes off. Several lines of information about the software appear with instructions:

The system has been interrupted prior to initializing the flash file system. The following
commands will initialize the flash file system, and finish loading the operating system
software#

flash_init

boot

Step 4 Initialize the flash file system:

switch: flash_init

Step 5 Connect the switch to a TFTP server through the Ethernet management port.

Step 6 Start the file transfer by using TFTP.

a. Specify the IP address of the TFTP server:

switch: set ip_addr ip_address/mask

b. Specify the default router:

switch: set default_router ip_address

Step 7 Copy the software image from the TFTP server to the switch:

switch: copy tftp://ip_address/filesystem:/source-file-url flash:image_filename.bin

Step 8 Boot up the newly downloaded Cisco IOS image.

switch: boot flash:image_filename.bin
