MSA 70 - diagnostics and firmware upgrade

Hi

I have MSA 70 - it is attached to P600. Where do I find diagnostics and firmware upgrade?

All the firmware upgrade that I found does NOT apply to P600 attached MSA.

Also is there a way to power cycle the MSA remotely? It seems there isn't a specific MSA management utility and the only way is to physically push the power button on the MSA which I can not.

Thanks
