5.2 1U/2U PCIe* Riser Card Accessory/Spare FRU Options
Each of the server board options within the Intel® Server S2600WF product family provides three riser slots. Riser slots #1 and #2 are capable of
supporting different riser card options to meet needs of specific system configurations. Riser card options for riser slots #1 and #2 are common. Riser
slot 3 is only supported in 2U system configurations and can only support a riser capable of supporting low profile PCIe* add-in cards.
All PCIe bus lanes to the riser slots are routed from the processors. Riser slot 1 has a total of 24 PCIe 3.0 bus lanes routed from both processors; 16
lanes from processor #1 and 8 lanes from processor #2. Riser slot #2 has a total of 24 PCIe 3.0 bus lanes routed from CPU 2. Riser slot #3 has a total
of 12 PCIe 3.0 bus lanes routed from CPU 2. See the product Technical Product Specifications (TPS) for additional information.
Riser slots #1 and #2 are capable of supporting up to 75W maximum power each. Available power to each add-in card slot on a given riser card is
defined by the PCIe specification. The server board provides two auxiliary 12V power connectors that when cabled (iPC AXXGPGPUCABLE), can
provide additional power to high power PCIe add-in cards.

One PCIe* add-in card slot – PCIe x16, x16 mechanical
Kit includes:
(1) Riser card PCBA
Each riser card assembly has support for a single full height, ½ length PCIe* add-in card. However, riser card #2 may be limited to ½ length, ½ height
add-in cards if either of the two mini-SAS HD connectors on the server board are used.
Note: Add-in cards that exceed the PCI specification for ½ length PCI add-in cards (167.65mm or 6.6in) may interfere with other installed devices on
the server board.
