recently I had an issue where the firmware on a 9200 switch was corrupted. This can help during an upgrade, or removal, etc.
After a reboot the switch came up to rom monitor mode, no biggie I thought- just copy the firmware from USB over to flash and install. This did not work, I continued to get error: “Unsupported destination device/filesystem.” see below-
switch: copy usbflash0:cat9k_lite_iosxe.17.03.04b.SPA.bin flash
Unsupported destination device/filesystem.
I then booted from the USB image and installed the system that way. My steps were:
- Frist check the file on USB and make sure its there/get the name.
switch: dir usbflash0:
Attributes Size Name
D-HS- 0 System Volume Information
—-A 482856473 cat9k_lite_iosxe.17.03.04b.SPA.bin
Then set my switch to boot to this value :
switch: boot usbflash0:cat9k_lite_iosxe.17.03.04b.SPA.bin
This fully loaded up the switch, and came up at a default setup screen. Once there I copied over the file VIA TFTP to flash. The device would not recognize the USB drive now (Probably cause I booted from it). Once copied to flash, I just installed normally, and rebooted.

This operation requires a reload of the system. Do you want to proceed?
Please confirm you have changed boot config to flash:packages.conf [y/n]y
IMPORTANT!!!
Next you have to change the boot config – or else it will go back to rom monitor.
config t
boot system flash:packages.conf
exit
wr mem
That’s it!
