Riser 1 provides Slot0-2; Riser2 provides Slot3-5; Riser3 provides Slot6-7; Riser4 provides
Slot8-9.
Riser 1 is optional: two 3.5-inch hard disk modules/PCIE full-height expansion modules
(choose 1 from 2):
When selecting the PCIE expansion module, Slot0 can be connected to PCIe X8 or PCIe X16
devices, Slot1 can be connected to PCIe X8 devices, and Slot2 can be connected to PCIe X16
devices. When 3.5-inch hard disk module is selected (this module supports a maximum of two
3.5-inch SAS/SATA hard disks), Slot0-2 cannot be connected to any device.
Riser 2 is the same as Riser 1 configuration.
