Migration To Install Mode From The Bootloader Prompt - Cisco Catalyst 3850 Deployment Manual

Migration to Install Mode from the Bootloader Prompt

The Cisco IOS XE Software image for the Cisco Catalyst 3850 Switch is distributed as a bundle image. You cannot
copy this bundle directly to the flash and then boot the switch. You must install the Cisco IOS XE Software bundle
into the flash and then boot the switch from the installed software using the install mode. Perform this procedure if
the Cisco IOS XE Software image that resides in the flash memory becomes corrupted.
Use the ping command to confirm TFTP connectivity from the boot loader prompt:
Boot the switch from TFTP:
Use the show version command to display the software image version and the mode:
The display shows bundle mode because the switch booted by loading the bundle either from TFTP or from a USB
flash drive.
Copy the final bundle image to the flash either from the TFTP server or from a USB flash drive.
Use the software expand command to expand the bundle image in the flash:
