I/O subsystem

The I/O subsystem consists of the core I/O and two optional I/O riser boards. Wake-on-LAN is
not enabled on any PCIe Public slots. The server does not support PCI Hot Plug (PHP).
The standard I/O Riser supports one full-height, full-length PCIe x8 and two full-height, half-length
PCIe x4 add-in cards. The second riser option supports one full-height, full-length PCIe x8, and one
full-height, half-length PCIe x8 add-in cards.
NOTE: All PCIe x8 slots are electrically connected as x8 slots but are physically loaded with x16
connectors.
The secondary I/O riser position can either be a riser that supports one full-height, full-length PCIe
x8 and two low-profile PCIe x4 add-in cards or a riser that supports one full-height, full-length PCIe
x8 and one low profile PCIe x8.
