scv2020 firmwere/repair/replace controller module

Hello everyone. 
I have a problem with my DELL SCv2020:

Main controller module (sn211689) don't start normally. Seems like problem with BIOS (pic. 1)

Secondary controller module (sn211688) (pic.2) loads in "safe mode" and not switch from this state. I try to change state in CLI, module demands login/pass, but it did not work. And USB-storage with file "unlock.phy" did not help (this USB works well on the different SCv2020).

I try to plug the secondary controller module in another SC, but can not load it in normal state, not in "safe mode".
