Chapter 2. Installing and removing the switch module

This chapter provides instructions for installing and for removing the switch 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 switches, Fibre Channel switches, Infiniband, and pass-thru modules.
The following illustration shows an example of a IBM Flex System chassis
(rear-view) with the I/O bays identified.

The IBM 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 IBM Flex System
chassis. For details about network adapter installation, configuration, and use, see
the documentation that comes with the IBM Flex System 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 IBM CN4093 10 Gb
Converged Scalable Switches. The IBM Flex System chassis supports a maximum
of 28 network adapters.

on the compute node, these I/O bays support any switch with the same type of
network interface that is used by the corresponding network adapter.
