The server board provides several connectors to provide power to various system options. The following sub-
sections will identify the location; provide the pin-out definition; and provide a brief usage description for each.
3.3.2 Riser Card Power Connectors
The server board includes two white 2x2-pin power connectors that provide supplemental power to high power
PCIe x16 add-in cards that have power requirements that exceed the 75W 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 225W, 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.
Each connector is labeled as “OPT_12V_PWR_1” and “OPT_12V_PWR_2” on the server board. The following
table provides the pin-out for both connectors.

The power cable (as shown above) for the OPT_12V_PWR_# connector is included in the following Riser Card
accessory kit options: Riser Slot #1 - AXX2UPCIEX16 and Riser Slot #2 - A2UL16RISER. The cable can
support both 6 and 8 pin 12V AUX power connectors located on the add-in cards.
3.3.3 Hot Swap Backplane Power Connector
The server board includes one white 2x4-pin power connector designated as the power source for any installed
hot swap backplanes. On the server board, this connector is labeled as “HSBP PWR”. The following table
provides the pin-out for this connector.
