I/O module
bay 4
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 IBM Flex System
EN2092 1Gb Ethernet Scalable Switch Modules. Depending on the type of IBM
Flex System chassis that you are using, the IBM Flex System chassis supports a
maximum of 10 or 14 network adapters.
Notes:
© Copyright IBM Corp. 2012 5

vI/O bays 1 and 2 support any standard Ethernet switch or pass-thru modules
that connects to the two integrated Ethernet controllers in each of the compute
nodes. When you install an adapter card in the first bay on the compute node,
the I/O bays support any switch with the same type of network interface that is
used in the corresponding compute node adapter bay.
vThe I/O bays 3 and 4 support Ethernet switch modules, Fibre Channel switch
modules, Infiniband, and pass-thru modules (optical and copper) if the serial
pass-thru modules are not being used. If you install an additional I/O module in
bay 3 or 4, a corresponding adapter card is required to be installed in each
compute node to access the I/O bay.
vThe compute nodes or IBM Flex System chassis that are described or shown in
this document might be different from your compute nodes or IBM Flex System
chassis. For additional information, see the documentation that comes with your
compute node or IBM Flex System chassis.
vWhen the switch is installed in a IBM Flex System chassis, the internal ports
operate at 10 Gbps or 1 Gbps. The external ports can operate at 10 Gbps or 1
Gbps, depending on the SFP module type.
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 7, 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 blade server 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, blade server, 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 a switch in the IBM Flex System chassis, you must also install
a compatible I/O expansion card in the blade server to support the switch.
vWhen you are finished working on the blade server 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:
61Gb Ethernet Scalable Switch: User's Guide

vEach of the module 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.
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/. See the
documentation that comes with the IBM Flex System chassis for cable-routing
information.
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 a switch
Note: The following illustration shows how to install a 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.
Chapter 2. Installing the switch 7

Use the following instructions to install a switch in the IBM Flex System chassis.
You can install a 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.
To install a switch, complete the following steps:
1. Read the safety information that begins on page v and “Installation
guidelines” on page 6.
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 and compute nodes.
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. If the removed filler module (from step 4) occupied two bays:
vRemove the single-high filler module from its static-protective package.
vInstall the single-high filler module into the unused bay.
7. Remove the switch from its static-protective package.
8. Make sure that the release levers on the switch are in the open position
(perpendicular to the switch).
9. Slide the switch into the applicable I/O-module bay until it stops.
10. 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.
Notes:
a. The switch takes approximately 60 seconds to complete the POST. When
the switch is turned on, an LED test occurs. All LEDs are lit and remain lit
during POST; then, all the LEDs except the OK LED turn off. This
indicates normal POST results.
81Gb Ethernet Scalable Switch: User's Guide

b. To maintain proper airflow, make sure that the ventilation holes on the
front of the switch are not blocked.
11. Make sure that the LEDs on the switch indicate that it is operating correctly
(see “Information LEDs” on page 16).
12. If you have another switch to install, repeat step 4 on page 8 through step 11;
otherwise, go to the next step.
13. Install the SFP+ modules in the switch. For information and instructions, see
“Installing and removing a 10 Gb SFP+ module” on page 12 and the
documentation that comes with the SFP+ module.
14. Attach any cables that are required by the switch. For additional information
about cabling the switch, see “Cabling the switch and the SFP+ module” on

To replace a switch, complete the following steps:
I/O module Handles
1. Read the safety information that begins on page v, and “Installation guidelines”
on page 6.
2. Disconnect any cables from the switch that you are removing. Removing these
cables (especially an Ethernet cable) disrupts the network connection from the
external Ethernet port to any connected external Ethernet devices. If you plan
to replace the switch with another switch, you can use the existing Ethernet
cable, provided that it remains securely attached to the Ethernet network. For
additional information about cabling the switch, see “Cabling the switch and
the SFP+ module” on page 10, the documentation that comes with the cables,
and the optional network devices to which the cables have been connected. For
