That error can be caused by many different issues.
Try some of the following steps:
1. Decommission/Reack server
2. In CLI, run the command "reset slot x/y" x=chassis # y=blade #
3. Change the power allocation policy to manual. Equipment > Global Policies > Global Power Allocation Policy > "Manual Blade Level Cap"
4. Move blade to a different slot
5. Reseat all components within the server
Let me know if any of those worked.
