bay 1 I/O module 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:
vI/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.

Installation guidelines
Before you install the switch in the IBM Flex System chassis, read the following
information:
vRead the safety information that begins on page v, “Handling static-sensitive
devices” on page 6, and the safety statements in the IBM Flex System chassis
documentation. This information provides a safe working environment.
vObserve good housekeeping in the area where you are working. Place removed
covers and other parts in a safe place.
vBlue on a component indicates touch points, where you can grip the component
to remove it from or install it in the compute node or IBM Flex System chassis,
open or close a latch, and so on.
vOrange on a component or an orange label on or near a component on the
switch, compute node, or IBM Flex System chassis indicates that the component
can be hot-swapped, which means that if the IBM Flex System chassis and
operating system support hot-swap capability, you can remove or install the
component while the IBM Flex System chassis is running. (Orange can also
indicate touch points on hot-swap components.) See the instructions for removing
or installing a specific hot-swap component for any additional procedures that
you might have to perform before you remove or install the component.
vYou do not have to turn off the IBM Flex System chassis to install or replace any
of the hot-swap modules on the front or rear of the IBM Flex System chassis.
vWhen you install the switch in the IBM Flex System chassis, you must also install
a compatible I/O network adapter in the compute node to support the switch.
vWhen you are finished working on the compute node or IBM Flex System
chassis, reinstall all safety shields, guards, labels, and ground wires.
vFor a list of supported optional devices for the IBM Flex System chassis and
other IBM products, see http://www.ibm.com/servers/eserver/serverproven/
compat/us/.
System reliability guidelines
To help ensure proper cooling, performance, and system reliability, make sure that
the following requirements are met:
vEach of the bays on the rear of the IBM Flex System chassis contains either a
module or a filler module.
vA removed hot-swap module is replaced with an identical module or filler module
within 1 minute of removal.
vA removed hot-swap compute node is replaced with another compute node or
filler node within 1 minute of removal.
Chapter 2. Installing and removing the switch module 5

vThe ventilation areas on the sides of the compute node are not blocked.
vYou have followed the reliability guidelines in the documentation that comes with
the IBM Flex System chassis.
Cable requirements for the switch are described in the IBM Configuration and
Options Guide at http://www.ibm.com/servers/eserver/xseries/cog/.
Handling static-sensitive devices
Attention: Static electricity can damage the IBM Flex System chassis and other
electronic devices. To avoid damage, keep static-sensitive devices in their
static-protective packages until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
vLimit your movement. Movement can cause static electricity to build up around
you.
vHandle the device carefully, holding it by its edges or its frame.
vDo not touch solder joints, pins, or exposed printed circuitry.
vDo not leave the device where others can handle and damage it.
vWhile the device is still in its static-protective package, touch it to an unpainted
metal surface of the IBM Flex System chassis or an unpainted metal surface on
any other grounded rack component in the rack that you are installing the device
in for at least 2 seconds. This drains static electricity from the package and from
your body.
vRemove the device from its package and install it directly into the IBM Flex
System chassis without setting down the device. If it is necessary to set down
the device, put it back into its static-protective package. Do not place the device
on the IBM Flex System chassis or on a metal surface.
vTake additional care when you handle devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
vSome types of IBM Flex System chassis come with electrostatic discharge (ESD)
connectors. If your unit is equipped with an ESD connector, see the
documentation that comes with the IBM Flex System chassis for using the ESD
connector.
Installing the switch
Note: The following illustration shows how to install the switch in a IBM Flex
System chassis. The appearance of your IBM Flex System chassis might be
different; see the documentation for your IBM Flex System chassis for
additional information.
Use the following instructions to install the switch in the IBM Flex System chassis.
You can install the switch while the IBM Flex System chassis is powered on. For
redundancy support, you must install I/O modules of the same type in I/O bays 1
and 2, and I/O modules of the same type in bays 3 and 4 of the chassis.
6EN4093 and EN4093R 10 Gb Scalable Switch: User's Guide

To install the switch, complete the following steps.
1. Read the safety information that begins on page v and “Installation guidelines”
on page 5.
2. Verify that the switch is compatible with the chassis. For a list of supported
optional devices for the IBM Flex System chassis and other IBM products, see
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
3. Select I/O bay in which to install the switch.
Note: For details about I/O bay requirements and bay locations, see the
documentation for the IBM Flex System chassis.
4. Remove the filler module from the selected bay. Store the filler module for
future use.
5. If you have not already done so, touch the static-protective package that
contains the switch to an unpainted metal surface of the IBM Flex System
chassis or an unpainted metal surface on any other grounded rack-component
for at least 2 seconds.
6. Remove the switch from its static-protective package.
7. Make sure that the release levers on the switch are in the open position
(perpendicular to the switch).
8. Slide the switch into the applicable I/O bay until it stops.
9. Push the release levers on the front of the switch to the closed position. After
you insert and lock the switch, it is turned on, and a power-on self-test (POST)
occurs to verify that the switch is operating correctly.
Note: The switch takes approximately 100 seconds to complete the POST.
During POST, the Power LED continuously flashes. Once POST has
successfully completed, the Power LED remains on and the Error LED
is off.
10. Make sure that the LEDs on the switch indicate that it is operating correctly
(see “Information LEDs” on page 16).
11. If you have another switch to install, repeat step 4 through step 10; otherwise,
go to the next step.
