Riser slots 1 and 2 are capable of supporting up to 100 W maximum power each. Available power to each
add-in card slot on a given riser card is defined by the PCIe* specification. Add-in cards with power
requirements above 75 W require the additional power to be drawn from either of two 2x2 pin
“OPT_12V_PWR” connectors on the server board. A 12 V aux power cable is routed from the “OPT_12V_
PWR” on the server board to a six- or eight-pin 12 V AUX power connector located on the add-in cards.
Note
: Both the two-slot PCIe riser card and the 12 V auxiliary power cable are included in accessory kit
A2UL16RISER2.
Configuration Note
: An add-in card that requires additional 12 V power and is installed in Riser Slot #1 must
have its AUX 12 V power connector located on the back edge of the card to avoid interference with the
chassis side wall.
High power add-in cards with passive cooling solutions (no fan on the heat sink) can only be supported in
systems configured with the high air flow air duct included in accessory kits AWFCOPRODUCTAD and
AWFCOPRODUCTBKT.

Air Duct Note
: The high air flow air duct included in accessory kit AWFCOPRODUCTAD includes two plastic
knock-out panels to allow for additional air flow over a specific riser card area. A knock-out panel is only
removed when installing a high power add-in card that is a double wide card with a passive heat sink
