Execute the boot command to load the IOS image specified in the boot parameter as shown below

Step 8 is the last step which is to boot the switch and verify that the switch successfully boots the IOS image placed into flash from xMODEM. Note that when doing this youРІР‚в„ўll need to disconnect your current console connection and change the baud speed on your terminal emulator from 115200 back to 9600. Once the boot parameter has been set you can now set the BAUD rate back to the default 9600bps by executing the command unset BAUD.

Once the IOS image is copied into flash youРІР‚в„ўll need to update the BOOT parameter by executing the set BOOT flash:filename.bin command as shown below Transferring .bin.Р”Р‡ile 'xmodem:' successfully copied to 'flash.bin' Switch: copy xmodem: flash.binР”В«egin the Xmodem or Xmodem-1K transfer now. Once setting the BAUD rate and reconnecting to the console line of your Cisco switch youРІР‚в„ўre ready to copy the IOS image via xModem to the switchРІР‚в„ўs flash memory by executing the copy xmodem: flash:filename.bin and starting the xModem file transfer from the terminal emulator client as shown below However if you do not set the BAUD to 115200 your file transfer can take up to 3 hours.

If you do this youРІР‚в„ўll need to disconnect your console session and change the serial line speed from 9600 to 115200. To speed up the xModem file transfer speed youРІР‚в„ўll need to set the console line BAUD rate to 115200 by executing the set BAUD 115200. Step 3 РІР‚вЂњ OPTIONAL РІР‚вЂњ If your image is corrupted you can format your flash file system by executing the format flash: command as shown below however this will delete your start-up configuration!!!Р”Р„re you sure you want to format 'flash:' (all data will be lost) (y/n)?yР”Р‡lashfs: flashfs fsck took 12 seconds. Once youРІР‚в„ўve booted into Switch ROM mode youРІР‚в„ўll need to initialize the flash file system by executing the flash_init command as shown below Р”Р‡lashfs: 0 orphaned files, 0 orphaned directoriesР”Р‡lashfs: flashfs fsck took 10 seconds.

Once youРІР‚в„ўve booted your switch into Switch ROM mode youРІР‚в„ўll be see the following dispatch Р”В«oot Sector Filesystem (bs) installed, fsid: 2Р”В«ase ethernet MAC Address: 00:14:f2:d2:41:80 You can check out the required procedure by clicking HERE!

This typically involves holding down the STAT button on the front of the switch when plugging in the power.

Unfortunately fixed configuration switches require the use of xModem to restore a corrupt or missing IOS images unlike the Cisco 4500 and Cisco 6500 Series supervisor engines which use compact flash cards Recovering the Cisco IOS Image on a fix configuration Cisco Catalyst Series Switch is quite a bit different and more of an РІР‚Сљold schoolРІР‚Сњ way of doing an IOS image recovery.

Boot the switch and verify that the switch boots properly.

Unset the baud so that it defaults back to 9600.

Set the boot parameter to the new image name located in Flash:.

Copy the Cisco IOS Image via xModem to Flash:.

Set the baud rate to 115200 to increase xmodem transfer speed and decrease time required to restore the IOS Image.

(This will remove your startup configuration)

OPTIONAL РІР‚вЂњ Format the flash file system if needed.
