A Lenovo Flex System network adapter must be installed in each compute node
with which you want to communicate. To enable the switch to communicate with a
compute node, at least one switch must be installed in the Lenovo Flex System

Installing a second switch enables a redundant path and a separate connection
from the compute node to the external Ethernet network.
