Installing the switch
When populating your IBM Flex System chassis, refer to the documentation that comes with your
chassis to determine the relevant order for populating the chassis I/O module bays.
A compatible 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 chassis. If only one switch is being used to populate the chassis, ensure that you
insert the switch in the recommended chassis I/O module bay. Refer to the support documentation
that comes with your IBM Flex System chassis and network adapter for more information.
Installing a second switch enables a redundant path and a separate connection from the compute
node to the external Ethernet switch.
The chassis supports a maximum of four IBM Flex System EN4023 10Gb Scalable Switches and a
maximum of 14 1-bay compute nodes.
See the documentation that comes with your IBM Flex System chassis for information about switch
bay locations and the components that can be installed in them that are specific to your chassis
type.

To install the switch, complete the following steps.
1. Read the following safety information:
2. Select the chassis bay in which to install the switch. For details about bay requirements and
3. Remove the filler panel from the selected bay. Store the filler panel for future use.
4. If you have not already done so, touch the static-protective package that contains the switch to
5. Remove the switch from its static-protective package.
Introduction
The compute nodes or chassis that are described or shown in this document might be different
from your compute nodes or chassis. For additional information, see the documentation that
comes with your compute nodes or chassis.
When the switch is installed in the chassis, the internal ports can operate at 10- or 1-Gbps
Ethernet; external ports can operate at 10-Gbps Ethernet through 10-Gbps SFP+ transceivers
(auto-negotiated) or 1-Gbps. Ports 57 and 58 can operate at 40-Gbps Ethernet or 4x10-Gbps
Ethernet when configured in breakout mode. For information on supported components, go to
the IBM Server Proven website at
http://www-03.ibm.com/systems/info/x86servers/serverproven/compat/us/flex.html.
Configuration requirements for the switch and chassis might vary. For the most up-to-date
product documentation for all of your IBM Flex System products, go to the IBM Flex System
Information Center at http://pic.dhe.ibm.com/infocenter/flexsys/information/index.jsp.
