S5000PSL Power Supply Signal Connector J9D1

I am in the early stages of having to design a server based on the S5000PSL board and am having problems finding a suitable power supply unit for it. My problem is the Power Supply Signal Connector J9D1 (Table 15 in the S5000PSL Tech Spech). Where does the flying lead for this come from? Is it from the power supply unit, in which case, what type of power supply unit should I be looking for? This connector has the following signals:-

SMB_CLK_ESB_FP_PWR_R

SMB_DAT_ESB_FP_PWR_R

SMB_ALRT_3_ESB_R

3.3V SENSE-

3.3V SENSE+

The last time I designed a server (a few years ago) I used an ATX power supply, but they dont have outputs like these.

Thanks for your help

This connector enables communication between the PSU and BMC, for management purpose. The http://www.intel.com/support/motherboards/server/chassis/sc5400/sb/CS-022718.htm SC5400 TPS section 5.4 may give you more details.

Thankyou. That certainly helped, but perhaps you can add a bit of information - is this power supply interface an international standard (as ATX appears to be) or just an Intel standard? Either way, does it have an identity?

Thankyou for your help. Just two more questions - is this psu interface an international standard or just an Intel standard (just like ATX seems to be)? Does it have an identity?

I keep trying to reply to this but my reply doesn't appear - does it take 24 hours to appear on the web?

If Yes then here is another couple of questions on the subject of these signals:-

1) Are the inputs to the motherboard, or outputs from the motherboard?

2) What would happen if I didn't connect them to anything?

Thanks for your help

This is defined in SSI EPS12V power supply specification. See http://www.pcpower.com/downloads/EPS12VSpec2_91.pdf http://www.pcpower.com/downloads/EPS12VSpec2_91.pdf section 6.1.7, 8.3~8.5 for details. If you don't connect it the power supply will still work, but the management features are not available.
