About Intel Black Box for common redundant power supply format question.

[AChen97]

Hello ,

I reading the CRPS design guide about PMBus Black box Command

The meaning as below:

Name: MFR_BLACKBOX

Format: Read Block with PEC (238 bytes)

Code: DCh

The content have "System Tracking Data(47 bytes)" and "Power supply event data(38 byte per event)",

and the "Power supply event " can record 5 event,

so.. the total length of the command as 47 bytes + (38 bytes *5 ) = 237 bytes,

I calculated the result with the design guide length is not equal (238 byte ≠ 237bytes),

Is anyone knew the correct format about this command(DCh) , or can tell me what's detail I missed?

Hi Jeremiah,

Thank your reply, and the Intel product I used is S2600 series,

I see the Technical Product Spec for S2600, and found the description as below:

First, I just want know how to decode the "Black Box" command from power supply(CRPS),

and next step I will connect to S2600 mother board.

By the way, Is it have different black box protocol in different mother board?

Many thanks,

The result is 1 byte-Data Length + 47 bytes-Tracking Data + 190 bytes-Event Data = 238 bytes ,

Many thanks and Best regards,
