exceed the 75 W maximum power supplied by the PCIe x16 riser slot. A cable from this connector may be
routed to a power connector on the given add-in card. Maximum power draw for each connector is 225 W,
but is also limited by available power provided by the power supply and the total power draw of the rest of
the system. A power budget for the complete system should be performed to determine how much
supplemental power is available to support any high power add-in cards configured in the system.
Each connector is labeled as “OPT_12V_PWR” on the server board. The following table provides the pin-out
for both connectors.

Figure 28. Power cable for the OPT_12V
The power cable for the OPT_12V_PWR connectors (shown in Figure 28) is included in the two-slot riser card
accessory kit (iPC – A2UL16RISER2 ) and can support both six- and eight-pin 12 V AUX power connectors
found on high power add-in cards.

Hot Swap Backplane Power Connector
The server board includes one white 2x6-pin power connector that is used to provide power for the hot
swap backplanes mounted in the front of the chassis only. On the server board, this connector is labeled as
“HSBP PWR”. The power for this connector is routed from two separate 12 V power rails, each capable of
supporting a current limit of 18 A. The following table provides the pin-out for this connector.
