Chapter 2. Installing and removing the switch module

This chapter provides instructions for installing and removing the switch module in
the IBM Flex System chassis. See the documentation for your IBM Flex System
chassis for information about I/O bay locations and the components that can be
installed in them that is specific to your IBM Flex System chassis type.
You can install up to four I/O modules in the IBM Flex System chassis, including
Ethernet switch modules, Fibre Channel switch modules, Infiniband, and pass-thru
modules (optical and copper).
The following illustration shows an example of a IBM Flex System chassis with the
I/O bays identified.

To enable the switch to communicate with a compute node, at least one switch
must be installed in the IBM Flex System chassis. For details about network
adapter installation, configuration, and use, see the documentation that comes with
the network adapter.
Installing a second switch enables a redundant path and a separate connection
from the compute node to the external Ethernet network.
The IBM Flex System chassis supports a maximum of four switch modules.
Depending on the type of IBM Flex System chassis that you are using, the IBM
Flex System chassis supports a maximum of ten or fourteen network adapters.
