Solved: C9200L-48T-4X Firmware update issue.

Thin · ‎12-02-2025

The current device firmware version is 17.03.04. If I want to upgrade to 17.12.06, are there any intermediate versions in between, or can I directly upgrade to 17.12.06?

Direct upgrade to 17.12.X is supported.

There will be a mandatory micro-code upgrade (aka mcu) and this will take another 5 minutes.
