The low-profile air duct used in the GPU enabled system option will accommodate 1U processor heat sinks
and allow support for four half-height/half-length PCIe add-in cards on the server board, one (1) GPU add-in
card (Full-Height Full-Length Double-wide) + one (1) Full-Height Half-Length PCIe add-in card from each
riser card assembly. The top side of the air duct has mounting features for an M.2 interface board capable of
supporting up to two (2) SATA M.2 SSDs, and support for one (1) Intel® RAID Maintenance Free Backup
(RMFBU) module.
The following illustrations identify the features found on the back panel for both the Standard and GPU
enabled system options. All I/O connectors, buttons, LEDs, OCP support, and power supply bays will be
common between the two system options.
The base Standard system option includes support for up to six (6) server board mounted PCIe* Gen3 add-in
cards. Riser card options adds support for an additional six (6) PCIe Gen 3 add-in cards
