MD3200i Controller not booting and can´t access via console

I have an MD3200i that was needing to replace battery. We did the procedure as recommended in Dell Manual.

But after reseat the controller, de iSCSI ports are flashing, but management port isn´t.

Tryed to access the controller via serial console, but got no response in terminal ( the other controller is responding)

Trying some suggestions from this forum, but didn´t get success:

Having those errors:

 

Also, this is a dual controller storage, but now wirte cache is disabled, there is any way to reenable write cache with only one controler if the second controller isn´t booting?
