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

Step 2. Load the new boot loader image from a TFTP server.
This example shows how to establish TFTP connectivity to the switch from the boot loader prompt:
switch: IP_ADDR=10.1.104.130/255.255.255.0
switch: DEFAULT_ROUTER=10.1.104.1
switch: MANUAL_BOOT=yes
switch: ping 10.1.104.211
ping 10.1.104.211 with 32 bytes of data ...
Up 1000 Mbps Full duplex (port 0) (SGMII)
Host 10.1.104.211 is alive.
This example shows how to copy the boot loader image from TFTP:
switch: copy tftp://10.1.104.211/cat3850_loader.img.12Sep12.SSA bs:
Up 1000 Mbps Full duplex (port 0) (SGMII)
...................................................................................................................................................................................................................................................
............................................................................................................................................................................................................................
File "tftp://10.1.104.211/cat3850_loader.img.12Sep12.SSA" successfully copied
to"bs:"
Note:
Step 3. Reset the switch.
The reset command reloads the switch, and it starts up with the new boot loader image:
switch: reset
To install the Cisco IOS XE Software, migrate from the boot loader prompt to the install mode.

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:
switch: ping 10.1.104.211
ping 10.1.104.211 with 32 bytes of data ...
Up 1000 Mbps Full duplex (port 0) (SGMII)
Host 10.1.104.211 is alive.
Boot the switch from TFTP:
switch: boot tftp://10.1.104.211/switch/cat3k_caa-universalk9.SPA.03.07.00.E.152-
3.E.bin
