Chapter 2. Installing and removing the switch module
This chapter provides instructions for installing and 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.

bay 3 I/O module
bay 2 I/O module
bay 4
An 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 EN4093 and
EN4093R 10 Gb scalable switches. The IBM Flex System chassis supports a
maximum of twenty-eight network adapters.
Notes:
v
I/O bays 1 and 2 support any standard IBM Flex System switch or pass-thru
module. When you install an I/O network adapter in the left fabric connector 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.
