CN4022 2-port 10Gb Converged Adapter
Some models of the x240 -- those with a model of the form 8737-xMx -- include the Flex System CN4022
2-port 10Gb Converged Adapter installed in slot 1. Table 2 lists the models with this adapter standard.
These models require that a compatible Ethernet switch be installed in I/O module bays 1 and 2 of the
chassis.
The features of the CN4022 2-port 10Gb Converged Adapter include the following features:
One Broadcom BCM57840 ASIC
Connection to either 1 Gb or 10 Gb data center infrastructure (1 Gb and 10 Gb auto-negotiation)
PCI Express 3.0 x8 host interface
Full line-rate performance
Supports 10 Gb Ethernet, FCoE, and iSCSI out of the box (no Features on Demand upgrade
required)
Supports vNIC - Switch Independent Mode

I/O expansion options
The x240 has two I/O expansion connectors for attaching I/O adapter cards. There is a third expansion
connector designed to connect an expansion node such as the PCIe Expansion Node. The I/O expansion
connectors are a very high-density 216-pin PCIe connector. Installing I/O adapter cards allows the server
to connect with switch modules in the Flex System Enterprise Chassis. Each slot has a PCI Express 3.0
x16 host interface and both slots support the same form-factor adapters.
The following figure shows the location of the I/O expansion connectors.

All I/O adapters are the same shape and can be used in any available slot.. A compatible switch or
pass-through module must be installed in the corresponding I/O bays in the chassis, as indicated in the
following table. Installing two switches means that all ports of the adapter are enabled, which improves
performance and network availability.
