bay 2

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

v I/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.

v The 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.

v The 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.

v When 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:

v Read 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.

v Observe good housekeeping in the area where you are working. Place removed

covers and other parts in a safe place.

v Blue 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.

v Orange 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.

v You 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.

v When 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.

v When you are finished working on the blade server or IBM Flex System chassis,

reinstall all safety shields, guards, labels, and ground wires.

v 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/.

System reliability guidelines

To help ensure proper cooling, performance, and system reliability, make sure that
the following requirements are met:

6 1Gb Ethernet Scalable Switch: User's Guide

v Each of the module bays on the rear of the IBM Flex System chassis contains

either a module or a filler module.

v A removed hot-swap module is replaced with an identical module or filler

module within 1 minute of removal.

v A removed hot-swap compute node is replaced with another compute node or

filler node within 1 minute of removal.

v The ventilation areas on the sides of the compute node are not blocked.

v You 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:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or its frame.

v Do not touch solder joints, pins, or exposed printed circuitry.

v Do not leave the device where others can handle and damage it.

v While 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.

v Remove 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.

v Take additional care when you handle devices during cold weather. Heating

reduces indoor humidity and increases static electricity.

v Some 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

Configuring the switch

The switch has an internal Ethernet path to the management module, 24 external
Ethernet ports, and a serial console port. The switch supports two remote-access
modes for management through Ethernet connections. You can select the mode
that is best suited for your IBM Flex System environment.

v Default mode: The default mode uses the internal path to the management

module only. In this mode, the remote-access link to the management console
must be attached to the Ethernet connector on the management module. The
Internet protocol (IP) addresses and SNMP parameters of the switches can be
automatically assigned by the IBM Director Flex System Deployment wizard
(when available), or you must assign them through the IBM Flex System
Management and Configuration program. This mode enables you to provide a
secure LAN for management of the IBM Flex Systems subsystems that is
separate from the data network. See “Establishing a TCP/IP session through the
management module” on page 19 for more information.

v Remote management mode: You can enable remote management of the switch

through the external ports, instead of or in addition to access through the
management module. This mode can be enabled only through the
management-module configuration interface. When this mode is enabled, the
twenty external RJ-45 ports and the four external SFP+ ports support both
management traffic and IBM Flex System application data traffic.

This mode enables the use of additional switch IP addresses on different IP
subnets than the management modules. This is useful when the switches are to

Chapter 2. Installing the switch 17

be managed and controlled as part of the overall network infrastructure, while
secure management of other IBM Flex System subsystems is maintained through
the management module. See “Enabling management through external ports” on
page 19 for additional instructions about configuring the switch for this mode of
operation.

The mini-USB console port provides an alternative path to manage and configure
the switch for local access.

Important:

v Before you configure the switch, make sure that the management modules in the

IBM Flex System chassis are correctly configured. For more information about
configuring the switch, see the following documents:

– IBM Flex System Advanced Management Module Installation Guide

– IBM Flex System Advanced Management Module User’s Guide

v The default IP address of the switch is 192.168.70.120, 192.168.70.121,

192.168.70.122, or 192.168.70.123, depending on the switch bay where it is
installed.

v If you change the IP address of the switch and restart the IBM Flex System

chassis, the switch maintains this new IP address as its default value.

v The management module and the switch can communicate with each other only

if they are on the same IP subnet.

v When you use the management-module Web interface to update the switch

configuration, the management-module firmware saves the new configuration in
its internal nonvolatile random-access memory (NVRAM). If the switch restarts,
the management module applies the saved configuration to the switch.

If the switch restarts and the management module cannot apply the saved
configuration, the switch defaults to using the configuration that it had
previously saved. If the IP subnet address of the switch does not match the IP
subnet address of the management module, you can no longer manage the
switch from the management module.

v For switch communication with a remote management station, such as an IBM

Director management server, through the management-module external Ethernet
port, the switch internal-network interface and the management-module external
interface must be on the same IP subnet.

For specific details about configuring the switch and preparing for system
installation, see the documentation listed in “Related documentation” on page 1.

Notes:

v Unless otherwise stated, references to the management module apply only to the

IBM Flex System Advanced Management Module, which is the only type of
management module that supports the switch.

v Throughout this document, the management-module Web-based user interface is

also known as the IBM Flex System management-module Web interface.

v Throughout this document, the user name is also known as the login name or

user ID for logging on to interfaces or programs.

v The screens that are described or referenced in this document might differ

slightly from the screens that are displayed by your system. Screen content
varies according to the type of IBM Flex System chassis and the firmware
versions and options that are installed.

Establishing a TCP/IP session through the management
module

To establish a TCP/IP session for the switch through the management module,
complete the following steps:

1. Log on to the management module as described in the User’s Guide or

Command Line Interface Reference Guide for your advanced management module.

If necessary, obtain the IP address of the management module from your
system administrator. The management-module window opens.

Note: The User ID and Password fields are case-sensitive. Type your

information in uppercase letters only. To maintain system security,
change your password after you log on for the first time. The default
User ID is USERID, and the default password is PASSW0RD (where the sixth
character is the number zero, not the letter O).

2. From the I/O Module Tasks menu, click Configuration.

3. In the I/O Module Configuration area, click the bay number that corresponds

to the location of the switch that you installed.

4. In the IP address field in the New Static IP Configuration area, type the new

TCP/IP address of the switch; then, click Save.

Note: The management module does not check for invalid IP addresses.

5. Click Advanced Configuration. You can now start a Web session or a Telnet

session.

The Web interface and the Telnet program provide different ways to access the
same internal-switching firmware and configure it.

v If your system application requires that you use the Web interface program, see

“Configuring the switch through the switch browser-based interface” on page 21
for additional information.

v If your system application requires that you use the Telnet program, see

“Configuring the switch through the Telnet interface” on page 20 for additional
information.

Enabling management through external ports

To access and manage the switch through external interfaces, you must enable the
external ports and the ability to manage the switch through them. Use the
information in the following table to configure your ports.

External management External ports Description

Disabled Disabled The switch must be managed

through the management

3. Click Advanced Configuration and make sure that external management is

enabled.

4. Click I/O Module Tasks → Admin/Power/Restart and make sure that the

external ports are enabled for the switch that you installed.

Configuring the switch through the Telnet interface

Note: Telnet is disabled by default.

The switch supports a command-line interface (CLI) that you can use to configure
and control the switch over the network through the Telnet program. You can use
the CLI to perform many basic network-management functions. In addition, you
can configure the switch for management through an SNMP-based
network-management system. The following sections describe how to use the
Telnet interface to access the switch, change its settings, and monitor its operation.

Connecting to the switch

If you know the IP address for the switch and you have an existing network
connection, you can use the Telnet program from an external management station
or the management module to access and control the switch. The management
station and the switch must be on the same IP subnet. If you have to obtain the IP
address for the switch or establish a network connection, contact your system or
network administrator. Be sure to use the correct IP address in the required
command, as specified in “Accessing the main menu.”

Accessing the main menu

To connect to the switch through the Telnet interface, complete the following steps:

1. From a DOS command-line prompt, type telnet x and press Enter.

where x is the IP address for the switch.

2. If you do not have an assigned initial password, in the Password field, type the

default password (PASSw0RD, spelled with a zero) and press Enter.

Important: The apply command changes the currently active configuration. If you
want your change to persist beyond the next reboot of the switch, you must enter
the save command. This command stores the current switch configuration and all
changes in nonvolatile memory.

20 1Gb Ethernet Scalable Switch: User's Guide

For more information about configuring through the CLI, see the IBM Application
Guide for the switch.

Configuring the switch through the serial-port interface

The mini-USB serial port provides basic communication through a terminal
emulation program (such as Hyperterminal). Because messages from the power-on
self-test (POST) and all initialization information are transmitted through the serial
port, you can use the serial port to log in to the switch and access and configure
the internal switching firmware.

To log in to the switch, complete the following steps:

1. Connect one end of the specifically designed serial cable that comes with your

device into the mini-USB port and connect the other end to the management
station.

For additional information, see “Connecting the serial console cable” on page

10.

2. On the management station, open a console window and make sure that the

serial port is configured with the following settings:

v 9600 baud

v 8 data bits

v No parity

v 1 stop bit

v No flow control

3. Type the user name and password. The default user name is USERID. The
default password is PASSW0RD. The password is spelled with a zero, not the
letter O.

The serial port is compatible with the standard 16550 Universal Asynchronous
Receiver/Transmitter (UART) protocol. The mini-USB serial port is enabled by
default.

Configuring the switch through the switch browser-based
interface

Note: HTTP is disabled by default. HTTPS is not disabled by default.

Before you can access and start the browser-based interface, make sure that you
have completed the following procedures:

v Install the switch in the IBM Flex System chassis.

v Make sure that the switch firmware is installed on the switch.

v Configure at least one IP interface on the switch.

Chapter 2. Installing the switch 21

v Enable frames and the JavaScript program in your Web browser.

The following hardware and software are required for the Web interface:

v A frame-capable Web-browser program, such as Internet Explorer (version 6.0 or

later), Mozilla Firefox (version 1.0.4 or later), or Netscape Navigator (version 4.7
or later)

v A computer or workstation with network access to the switch

To start the browser-based interface, complete the following steps:

1. Start a Web browser. The Web-browser window opens.

2. In the URL field, enter the IP address of the switch, in the following format:

http://xxx.xxx.xxx.xxx. The login window opens.

3. Enter the switch user ID and password and click OK. The default user ID is

USERID. The default password is PASSW0RD. The password is spelled with a zero,
not the letter O.

Note: The passwords that are used to access the switch are case-sensitive. To

increase system security, change the password after you log on for the first
time.

Initial configuration

The operating firmware on the switch contains default configuration files that are
installed during the firmware installation. These initial configuration settings are
not in a separate configuration file but are components of the firmware. When you
restore the management module to factory defaults, the original configuration is
restored. For more information about configuring and managing the switch
through the management module, see the Command Reference for the switch.

Logging in to the switch

The switch supports user-based security that enables you to prevent unauthorized
users from accessing the switch or changing its settings.

To log in to the switch, complete the following steps:

1. At the prompt, type your user ID and press Enter. The default user ID is

USERID.

2. Type your password and press Enter. The default password is PASSW0RD. The

password is spelled with a zero, not the letter O. The main-menu window
opens.

After you log on to the switch, you must set the date and time. See the Command
Reference for the switch to perform this task and others as needed.

Obtaining the latest level of switch firmware

The latest firmware update for the IBM Flex System EN2092 1Gb Ethernet Scalable
Switch is available at the following site: http://www.ibm.com/supportportal/

Note: Changes are made periodically to the IBM Web site. The procedure for

locating firmware and documentation might change from what is described
in this document.

Upgrading the switch firmware

You can upgrade the switch firmware by using a TFTP server application.
Typically, this firmware runs as an application under your operating system. Make
sure that this firmware is installed on your server; then, download the firmware
images from http://www.ibm.com/systems/support/ into a directory on your
TFTP server. Enable the TFTP server and set its default directory to the one where
the image is.

To transfer the firmware image files from the TFTP server to the switch, you can
establish a Telnet session through the management module. Ping the TFTP server
to make sure that you have a connection. The Telnet session performs optimally if

© Copyright IBM Corp. 2012 23

all three network entities (TFTP server, management module, and switch IP
addresses) are on the same subnet. Otherwise, you must use a router and configure
a gateway address on the switch. Use the management-module interface to
configure the IP addresses of the management module external interface (eth0) and
the switch so that they are both on the same subnet as the TFTP server.

Examples of IP addresses and masks are described in the following table.

Network entity IP address Mask

TFTP server 192.168.2.178 255.255.255.0

Management module (eth0) 192.168.2.237 255.255.255.0

Switch-module current IP
configuration (IF 128)

192.168.2.51 255.255.255.0

Note: With this configuration, you can ping the switch from the TFTP server.

Access the switch command line interface (CLI). Refer to “Configuring the switch
through the Telnet interface” on page 20 for more information.

To upgrade the switch firmware, complete the following steps:

1. Log in to the switch.

2. At the CLI prompt, type the following command and press Enter.

/boot/gtimg imageX TADDR zzzzz

where imagex is the image to install and zzzzz is the operating-system image
file name.

3. At the CLI prompt, type the following command and press Enter.

/boot/gtimg boot TADDR yyyy

Where yyyy is the boot image file name.

4. Press Enter for user name.

5. Enter data path (either mgt or data).

6. Reset and restart the switch as described in “Resetting and restarting the

switch.”

Resetting and restarting the switch

To activate the new image or images, you must reset the switch. To reset the
switch, complete the following steps:

1. Log on to the management module CLI as described in the switch's User's

Guide or CLI Reference Guide. If necessary, obtain the IP address of the

management module from your system administrator.

2. Set the environment to the bay where you installed the switch. For example:

system> env -T system:switch[1]

3. Issue the reset command to restart the switch:

system:mm[1]> env -T system:switch[1]
system:switch[1]> reset

4. Wait approximately 100 seconds for POST to complete.

5. Issue the info command for the switch that was just restarted and note the

corresponding level of the firmware for the switch. Confirm that the firmware

Chapter 4. Solving problems

This section provides basic troubleshooting information to help you solve some
problems that might occur while you are setting up the switch. The Application
Guide for the switch provides more details about troubleshooting the switch.

If you cannot locate and correct a problem by using the information in this section,
see Appendix A, “Getting help and technical assistance,” on page 29.

Running POST

To ensure that it is fully operational, the switch processes a series of tests during
power-up or a restart (power-on self-test, or POST). These tests take approximately
1 minute to complete. The management module reads the test results and displays
them for you. During normal operation, these tests are completed without error,
and the green OK LED is lit. However, if the switch fails POST, the yellow switch
error LED and the system-error LED on the IBM Flex System chassis are lit. An
event is stored in the event log in the system status panel of the management
module. The specific failure is displayed on the system status I/O module panel of
the management module.

Note: For the locations and descriptions of the switch LEDs, see “Locating the

information panels, LEDs, and external ports” on page 14.

POST errors

There are two types of errors: noncritical and critical. A noncritical error applies to
one port, and the switch is operational. You can continue to operate the switch;
however, you must replace it as soon as possible. When critical errors occur, the
switch does not operate. To view POST results, complete the following steps:

1. Log on to the management module as described in the IBM Flex System Chassis
Management Module Command-Line Interface Reference Guide. If necessary, obtain

the IP address of the management module from your system administrator. The
login window opens.

2. Turn off the power to the switch; then, turn it on again.

3. After POST is completed, the management module displays the results. Refresh

the window to view the POST results. If a critical error occurs, replace the
switch. If a noncritical error occurs, see the switch error log for additional
details.

The following table describes the basic critical and noncritical failures. This
abbreviated list is representative; it is not an exhaustive list. An error code is
associated with each failure. Error codes are displayed on the Management Module
Switch Information window. Be sure to note the applicable error code and
corresponding failure. You might have to provide this information when you call
for service. For details, see Appendix A, “Getting help and technical assistance,” on
page 29.
