WLC 2504 FUS 1.9.0.0 or 2.0.0.0?

[danibqb01]

Hello guys!

How can I identify which FUS is running on WLC 2504?

Is it version 1.9.0.0 or version 2.0.0.0?

I know it's one of two versions, but how do I identify which one?

The documentation does not make it clear!

Should be fine.

This is probably FUS 2.0, but only TAC can tell you for sure.
But based on this document you have FUS 2.0: https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/fus-rn-20.html

You already got FUS 2.0.0.0.

By looking at bootloader version you can tell it.

Note :  Verify the bootloader version by entering the command show sysinfo. The output displays the following line only if FUS 2.0 is installed.
Bootloader Version................... 1.0.20

In the FUS 1.9.0.0 Release Notes, it also shows that Bootloader is updated to 1.0.20.

Does the firmware version "PIC 16.0" have any relation? Because I have another WLC that this information is different: "PIC 20.0"

You are right. Boot loader upgraded to 1.0.20 in FUS 1.9 as well.

Real differentiator is the PIC 20 value. It is stated in FUS 2.0 release notes. 

FUS 2.0 is to address CSCuu46671 in 2504.

I upgraded FUS to 2.0.0.0 and the information remained the same:

(Cisco Controller) >show sysinfo

Manufacturer's Name.............................. Cisco Systems Inc.
Product Name..................................... Cisco Controller
Build Info....................................... Engineering Special
Product Version.................................. 8.5.140.0
Bootloader Version............................... 1.0.20
Field Recovery Image Version..................... 7.6.101.1
Firmware Version................................. PIC 16.0

I thought PIC 16.0 would change to PIC 20.0, but it didn't change after the upgrade!

The only certainty I have now is that WLC is running FUS 2.0.0.0. If before the FUS upgrade the version was 1.9 or 2.0 we will never know.

It really is confusing to know if it is 1.9 or 2.0.

Thank you all for the clarification!
