Network adapters
As described in "Embedded 1 Gb Ethernet Adapter," certain models have a Embedded 1 Gb Ethernet
controller on the system board, and its ports are routed to the midplane and switches installed in the
chassis through a Compute Note Fabric Connector that takes the place of an adapter in I/O slot 1.
Models without the Embedded 1 Gb Ethernet controller do not include any other Ethernet connections to
the Enterprise Chassis midplane as standard. Therefore, for those models, an I/O adapter must be
installed in either I/O connector 1 or I/O connector 2 to provide network connectivity between the server
and the chassis midplane and ultimately to the network switches.
The following table lists the supported network adapters and upgrades. Adapters can be installed in either
slot. However, compatible switches must be installed in the corresponding bays of the chassis. All
adapters can also be installed in the PCIe Expansion Node.

* For models with the Embedded 1 Gb Ethernet controller standard, the Compute Node Fabric Connector occupies
the same space as an I/O adapter in I/O slot 1, so you have to remove the Fabric Connector if you plan to install an
adapter in I/O slot 1.
