Flex System x240 Compute Node (E5-2600 v2) 30

Network adapters

As described in "Embedded 10Gb Virtual Fabric Adapter," certain models (those with a model number of

the form 8737-x4x or 8737-xDx) have a 10Gb Ethernet controller on the system board, and its ports are

routed to the midplane and switches installed in the chassis via a Compute Note Fabric Connector that

takes the place of an adapter in I/O slot 1.

Models without the Embedded 10Gb Virtual Fabric Adapter (those with a model number of the form

8737-x2x) 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. The "Maximum supported" column indicates

the number of adapter than can be installed in the server and in the PCIe Expansion Node (PEN).

* For x4x models (where the Embedded 10Gb Virtual Fabric Adapter standard), and for xMx models (where a

CN4022 2-port 10Gb Converged Adapter is standard), only one extra adapter can be installed in the compute node.
