IBM Flex System x440 Compute Node 21
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.
