I/O subsystem
The I/O subsystem is made up 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 other riser option when loaded in the primary position has a
iLO/RMII/NC-SI connector to use with certain NIC add in cards that will allow iLO sideband
connections. This 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.
