C3000 enclosure with 4 * BL460c GEN8 and 3 * BL460C GEN10

[JooKal]

We have a problem with a C3000 enclosure and 4 * BL460C GEN8 and 3 * BL460c GEN10
If I have the GEN8 server on. 
I can turn two GEN10 servers on without problems but if the third GEN10 server power on, 
two of the three GEN10 servers go power off with a Device Operational Error power off.
In the IML log we get the following message
Rack Infrastructure 07/16/2019 13:26:43 07/16/2019 13:26:43
 1 Server Blade Enclosure Power Request Denied: Enclosure Busy 
(Enclosure Serial Number Cxxxxxxxx, Bay 2)
OA firmware is 4.90 power managemeent 1.04 feb 2019.
The question is is this supported configuration or have we a other problemen.
The customer uses multiple C3000 with 6* GEN8 and 2* GEN10 servers without problems
