Hello EMC specialists,

I would like to get your help on a big problem that I have met for the first time :

I have a CX300 system which was fully operational.

I have checked the logs, and I have seen a message that I have not kept, telling that the battery is failed.

I have removed the storage processor and I have replaced the lithium battery, which was completely discharged : 1,2 V for a 3V battery.

After battery replacement, I have verified the voltage on pins, and I have plugged again the storage processor, but now it is unreachable :

At power up, the status LED stays on the phase : 1 flash for 4 seconds.

No activity on drives 0 and 2 for SPA boot.

There is no traffic at all on the serial management bus, and the SP stays not pingable.

I have followed the ESD rules, and the SP was on an antistatic bag when I have changed the battery.

Could you tell me if I have forgotten a specific step, and could you tell me how to restart the system normally ?

Normally I should get :

And this is that I have on SP B :
