%C6KPWR-4-DISABLED: power to module in slot 4 set off (New fabric sync sequence not supported)

We are using Cat6509-V-E chassis with redundant SUP-2T with ACE module. We are running IOS version: bootdisk:s2t54-advipservicesk9_npe-mz.SPA.150-1.SY.bin

ACE version: 4.1

We installed ACE on module 4 & 1. But in both the cases we are getting the following error message:
Router# *Feb 1 10:53:25.459: %C6KPWR-4-DISABLED: power to module in slot 4 set off (New fabric sync sequence not supported)
Router# *Feb 1 11:51:25.459: %C6KPWR-4-DISABLED: power to module in slot 1 set off (New fabric sync sequence not supported)

Any suggestions to resolve this?

A4(1.0) code. This is not a supported version on SUP2T(chassis hardware
being used by you). Please click here for the release notes.

The minimum required ACE30 module software version for Supervisor Engine 2T support is A4(2.1a) or later. This ACE software version supports both supervisor engine models: VS-S2T-10G and VS-S2T-10G-XL.

This is the reason for getting "New fabric sync sequence not supported" messages. Therefore please upgrade ACE module to A4(2.1) in order to run it on SUP2T. I would request you to seat this module in a supported SUP hardware like SUP720. Once loaded, please upgrade to A4(2.1). Then you can plug it back to the current SUP. It was supported finally in A4(2.1) upwards.
