Smart Array P410i Controller: Array Accelerator is disabled

I have a DL380 G7 server, with P410 controller and a 1GB cache module. 

I bought a SAS expander (468406-B21) and a new cage (516914-B21). I installed them with attention to cabling instruction. I powered on the server, I saw this POST message:

I found that cache module has been disabled. I updated the firmware using SPP G7.1 , but there is no change.

These are ADU screenshots:
