The slot is not available to install other adapters in the expanded function system backplane.
Two PCIe generation 3 (PCIe3) switches in the system backplane provide PCIe3 busses from the system
processor modules that provide connectivity to the following features:
v PCIe slots
v
Embedded PCIe local area network (LAN) controller
v PCIe3 internal SAS controller
v PCIe3 USB controller
The two PCIe3 switches follow:
v PCIe3 Switch 1 that provides PCIe buses from Processor Module 1, Chip-0.
v PCIe3 Switch 2 that provides PCIe buses from Processor Module 1, Chip-1.
Table 3 lists the features provided by the PCIe3 switches.
