Intel® Server System R2000LH2/T2 Product Family TPS PCI Riser Card Support
Revision 1.0 77
9. PCI Riser Card Support
The system includes two riser card slots on the server board. Available riser cards can be used
in either slot. This chapter provides an overview of each available riser card and describes the
server board features and architecture supporting them.
9.1 Riser Slot Overview
The server system supports two 3-slot riser cards identified by IO Riser 1 (Right) and IO Riser 2
(Left). The two 3- slot PCIe Risers each support up to x48 lanes of PCIe Gen3 through a custom
interconnect (3 connector blocks at 120 pins per connector, 360pins total).The PCIe signals for
each riser card slot are supported each by two installed processors.
Additional support:

One double wide GPGPU or Graphics card per riser (up to 300W active supported,
passive not supported)
OR

Two single wide GPGPU or Graphics cards per riser (up to 150W active supported;
passive not supported)
OR

Two single wide full height, full length (FHFL) cards per riser (25W supported for each)
OR

Three single wide full height, half length (FHHL) cards per riser (one of these are internal
only slots). Un-shadowed PCIe slots support 25W each and shadowed supports 10W
each

3.3V VR for PCIe card power is located on the riser
