Installation Guidelines
Before you install the switch module in the blade server, read these guidelines:
•Review and become familiar with the safety and handling guidelines specified in the blade server
Product Information Guide.
•Review the “Warnings” section on page 2-2 and the Regulatory Compliance and Safety Information
for the Cisco Catalyst Blade Switch 3020 for HP that accompanies this guide.
Consider these prerequisites before installing your switch module:
•Fill any unoccupied interconnect bays or any unoccupied power module bays in the blade server
with blanks.
•Identify the bays in which you will insert the switch modules. Plan to install the first switch module
in bay 1, the second in bay 2, and so on up to bay 8, if possible. The bay in which you choose to
install each switch module depends on whether mezzanine or Ethernet cards are installed in the
blade server and how they are configured. See the blade server documentation for more information
about installing and configuring the mezzanine or Ethernet cards.
The interconnect module bays are physically interconnected in pairs through the blade server
backplane. That is, each of these pairs—bays 1 and 2, bays 3 and 4, bays 5 and 6, and bays 7 and
8—are interconnected. If you install two switch modules in one of the paired bays, they are
internally interconnected. You must configure the switch modules to logically enable the
interconnect ports, Gigabit Ethernet ports 23 and 24. See the switch module software configuration
guide for information on configuring these ports.
•See the HP c-Class documentation for information on the port mapping between blade servers and
the switch modules.
Caution To prevent electrostatic-discharge (ESD) damage when installing switch modules, follow your normal
board and component handling procedures.
Note When you install a switch module, you do not need to power down the server modules or the enclosure.
Note The initial configuration assumes that the switch module was never configured, that it is in the same state
as when it was received, and that it is not configured with a default username and password.
Be sure to observe these requirements:
•For copper Ethernet ports, cable lengths from the switch module to connected devices can be up to
328 feet (100 meters).
•See the documentation for the SFP module for more information about cable specifications for the
SFP module connections. Each port must match the wave-length specifications on the other end of
the cable, and the cable must not exceed the stipulated cable length for reliable communications.
Note When using shorter lengths of single-mode fiber-optic cable, you might need to insert an inline
optical attenuator in the link to avoid overloading the receiver.

Step 6 Push the release latch on the front of the switch module to the closed position.
Switch Module IP Addresses
IP addresses can be assigned to two of the switch module interfaces:
•The fa0 Ethernet interface. This Layer 3 Ethernet interface is connected to the Onboard
Administrator through which you can manage the switch module. It is used only for switch module
management traffic, not for data traffic.
•The VLAN 1 interface. You can manage the switch module from any of its external ports through
VLAN 1.
If you want to assign the VLAN 1 IP address through Express Setup, you must start that process
immediately after installing the switch module in the blade server. If you miss the opportunity to have
the IP address assigned in this way, you can remove and then re-install the switch module. See the
“Running Express Setup” section on page 2-9 for instructions.
When you install the switch module, you need to determine whether the Onboard Administrator is
connected to a network in which a DHCP server is also connected or if the Onboard Administrator has
been configured as a DHCP server. If either of these conditions is true, the switch module automatically

obtains an IP address for its fa0 Ethernet interface that is connected to the Onboard Administrator. In
this case, a VLAN 1 IP address is not assigned, and to set up the switch module by using the Device
Manager you must use the fa0 interface IP address that the DHCP server assigns.
See the “Using the Onboard Administrator to Assign an IP Address to the Switch Module fa0 Interface”
section on page 2-12 for how to set up the switch module if the IP address is being assigned dynamically.
Running Express Setup
To run Express Setup, you need a PC and an Ethernet (Category 5) straight-through cable (as shown):
Before you run Express Setup, you must set up your switch module to communicate with a
Hyperterminal program.
Note The initial configuration assumes that the switch module was never configured, that it is in the same state
as when it was received, and that it is not configured with a default username and password.
Note To set up the switch module by using the command-line interface (CLI), see the switch module hardware
installation guide on cisco.com.
Information You Need to Run Express Setup
You need this information about your switch module from your system administrator before you
complete the setup program:
•Fixed IP address
•Subnet mask (IP netmask)
•Default gateway IP address
You can also configure these optional parameters through the Express Setup program:
•Local access password
•Telnet access password
•Names of the SNMP read and write community strings if you are going to use a
network-management program like CiscoWorks.
•Host name, system contact, and system location
When you first set up the switch module, you can use Express Setup to enter the initial IP information.
Doing this enables the switch module to connect to local routers and the Internet. You can then access
the switch module through the IP address for further configuration.

Chapter 2 Switch Installation
Running Express Setup
Using Express Setup to Assign a VLAN 1 IP Address to the Switch Module
Use these steps to assign an IP address to the VLAN 1 interface through Express Setup. You must start
these steps immediately after you have installed the switch module (see the “Installing the Switch
Module in the Blade Server” section on page 2-6).
Note If approximately 2 minutes pass after you press the Mode button, obtaining the VLAN 1 IP address
through Express Setup is no longer possible unless you remove and then re-install the switch module.
To prepare the switch module:
Step 1 Verify that no devices are connected to the switch module, because during Express Setup, the switch
module acts as a DHCP server. If your PC has a static IP address, before you begin you should change
your PC settings to temporarily use DHCP.
As the switch module powers on, it begins the power-on self-test (POST), a series of tests that runs
automatically to ensure that the switch module functions properly.
Step 2 Wait for the switch module to complete POST. It might take several minutes for the switch module to
complete POST.
Step 3 Verify that POST has completed by confirming that the system and status LEDs remain green.
Step 4 If the switch module fails POST, the system LED turns amber. If the POST fails, see the “Understanding
POST Results” section on page 3-1 to determine a course of action. POST errors are usually fatal. Call
Cisco Systems immediately if your switch module fails POST.
Step 5 Press and hold the Mode button until the four LEDs next to the Mode button turn green. This takes
approximately 3 seconds. (See Figure 2-5.)
Figure 2-5 Press and Hold the Mode Button
Step 6 Release the Mode button.
If the LEDs next to the Mode button begin to blink after you press the button, release it. Blinking LEDs
mean that the switch module has already been configured and cannot go into Express Setup mode.

Step 11 Go to “Completing the Express Setup Fields” section on page 2-14 to finish setting up the switch module
using the Express Setup screen of the Device Manager.
Using the Onboard Administrator to Assign an IP Address to the Switch Module
fa0 Interface
For the switch module to obtain an IP address for the fa0 interface through the Onboard Administrator,
these conditions must be met:
•The blade server is powered on and connected to the network.
•Basic configuration of the Onboard Administrator is completed, and you have the username and
password for the Onboard Administrator.
•A DHCP server is configured on the network segment to which the blade server is connected, or the
Onboard Administrator is configured to run as a DHCP server.
Note See the Onboard Administrator user guide at http://www.hp.com/go/bladesystem/documentation for
more information about configuring and using the Onboard Administrator.
After you install the switch module in the interconnect module bay, after approximately 2 minutes, the
switch module automatically obtains an IP address for its fa0 interface through the Onboard
Administrator. This method of obtaining an IP address occurs if a DCHP server is configured on the same
network, or if the Onboard Administrator is configured as a DHCP server. If you prefer to use Express
Setup to assign the switch module IP address to the VLAN 1 interface, you must start the Express Setup
steps immediately after you install the switch module.
After you have installed the switch module (see the “Installing the Switch Module in the Blade Server”
section on page 2-6), it powers on. As it powers on, the switch module begins the POST, a series of tests
that runs automatically to ensure that the switch module functions properly.

POST Results” section on page 3-1 to determine a course of action. POST errors are usually fatal. Call
Cisco Systems immediately if your switch module fails POST.
Step 4 Wait approximately 2 minutes for the switch module to get the software image from its flash memory
and begin autoinstallation.
Step 5 Using a PC that is connected to the same network segment as the blade server Onboard Administrator,
access the Onboard Administrator in a browser window.

using the Express Setup screen of the Device Manager.
Completing the Express Setup Fields
Follow these steps to finish setting up the switch module:
Step 1 Enter this information in the Network Settings fields:
– In the Management Interface (VLAN ID) field, the default is 1. Enter a new VLAN ID only
if you want to change the management interface through which you manage the switch module
and to which you assign IP information. The VLAN ID range is 1 to 1001.
– In the IP Address field, enter the IP address of the switch module. In the IP Subnet Mask field,
click the drop-down arrow, and select an IP Subnet Mask.
– In the Default Gateway field, enter the IP address for the default gateway (router).
– Enter your password in the Switch Password field. The password can be from 1 to 25
alphanumeric characters, can start with a number, is case sensitive, allows embedded spaces,
but does not allow spaces at the beginning or end. In the Confirm Switch Password field, enter
your password again.
Step 2 (Optional) You can enter the Optional Settings information now or enter it later by using the device
manager interface:
– In the Host Name field, enter a name for the switch module. The host name is limited to
31 characters; embedded spaces are not allowed.
– In the System Contact field, enter the name of the person who is responsible for the switch
module. In the System Location field, enter the wiring closet, floor, or building where the
switch module is located.
– In the Telnet Access field, click Enable if you are going to use Telnet to manage the switch
module by using the CLI. If you enable Telnet access, you must enter a Telnet password.

2-15
Cisco Catalyst Blade Switch 3020 for HP Hardware Installation Guide
OL-8914-02
Chapter 2 Switch Installation
Installing and Removing SFP Modules
– In the Telnet Password field, enter a password. The Telnet password can be from 1 to 25
alphanumeric characters, is case sensitive, allows embedded spaces, but does not allow spaces
at the beginning or end. In the Confirm Telnet Password field, re-enter the Telnet password.
– In the SNMP field, click Enable to enable Simple Network Management Protocol (SNMP).
Enable SNMP only if you plan to manage the switch modules by using CiscoWorks 2000 or
another SNMP-based network-management system.
– If you enable SNMP, you must enter a community string in the SNMP Read Community field,
the SNMP Write Community field, or both. SNMP community strings authenticate access to
MIB objects. Embedded spaces are not allowed in SNMP community strings. When you set the
SNMP read community, you can access SNMP information, but you cannot modify it. When
you set the SNMP write community, you can both access and modify SNMP information.
Step 3 Click Submit to save your settings, or click Cancel to clear your settings.
When you click Submit, the switch module is configured and exits Express Setup mode. The PC displays
a warning message and then attempts to connect with the new switch module IP address. If you
configured the switch module with an IP address that is in a different subnet from the PC, connectivity
between the PC and the switch module is lost.
Step 4 Disconnect the switch module from the PC, and install the switch module in your network. See the
“Management Options” section on page 1-6 for information about configuring and managing the switch
module.
If you need to rerun Express Setup, see the “Running Express Setup” section on page 2-9.
To install additional switch modules, repeat the steps in the “Installing the Switch Module in the Blade
Server” section on page 2-6 through the “Running Express Setup” section on page 2-9.
Refreshing the PC IP Address
After you complete Express Setup, you should refresh the PC IP address:
•For a dynamically assigned IP address, disconnect the PC from the switch module, and reconnect
the PC to the network. The network DHCP server assigns a new IP address to the PC.
•For a statically assigned IP address, change it to the previously configured IP address.
Installing and Removing SFP Modules
These sections describe how to install and remove SFP modules. The modules are inserted into the
SFP module slots on the front of the switch module. These field-replaceable modules provide uplink
interfaces.
You can use any combination of SFP modules. Refer to the switch module release notes for the list of
SFP modules that the switch module supports. Each port must match the wave-length specifications on
the other end of the cable, and the cable must not exceed the stipulated cable length for reliable
communications. See the “Installation Guidelines” section on page 2-3 for cable stipulations for
SFP connections.

Chapter 2 Switch Installation
Installing and Removing SFP Modules
Use only Cisco SFP modules on the switch module. Each SFP module has an internal serial EEPROM
that is encoded with security information. This encoding provides a way for Cisco to identify and
validate that the SFP module meets the requirements for the switch module.
•For detailed instructions on installing, removing, and cabling the SFP module, refer to your
SFP module documentation.
Installing SFP Modules into SFP Module Slots
Figure 2-10 shows an SFP module that has a bale-clasp latch.
Caution We strongly recommend that you do not install or remove fiber-optic SFP modules with cables attached
because of the potential damage to the cables, the cable connector, or the optical interfaces in the
SFP module. Disconnect all cables before removing or installing an SFP module.
Removing and installing an SFP module can shorten its useful life. Do not remove and insert
SFP modules more often than is absolutely necessary.
Figure 2-10 SFP Module with a Bale-Clasp Latch
To insert an SFP module into the module slot, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the enclosure.
Step 2 Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.
Note On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows
that show the direction of the connection, either send or receive (TX or RX).
Step 3 Align the SFP module in front of the slot opening.

Connecting to the 10/100/1000 Ports
Step 5 Grasp the SFP module between your thumb and index finger, and carefully remove it from the
module slot.
Step 6 Place the removed SFP module in an antistatic bag or other protective environment.
Connecting to the 10/100/1000 Ports
The switch module 10/100/1000 ports configure themselves to operate at the speed of attached devices.
If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex
parameters. Connecting devices that do not autonegotiate or that have their speed and duplex parameters
manually set can reduce performance or result in no linkage.
To maximize performance, choose one of these methods for configuring the Ethernet ports:
•Let the ports autonegotiate both speed and duplex.
•Set the port speed and duplex parameters on both ends of the connection.
Follow these steps to connect to 10BASE-T, 100BASE-TX or 1000BASE-T devices:
Caution To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling
procedures.
Step 1 When connecting to workstations, servers, routers, and Cisco IP Phones, connect a straight-through
cable to an RJ-45 connector on the front panel. (See Figure 2-13.) When connecting to switches or
repeaters, use a crossover cable. (See the “Cable and Adapter Specifications” section on page B-3 for
cable-pinout descriptions.)

Connecting to SFP Modules
Note You can use the mdix auto interface configuration command in the CLI to enable the automatic
medium-dependent interface crossover (auto-MDIX) feature. When the auto-MDIX feature is enabled,
the switch module detects the required cable type for copper Ethernet connections and configures the
interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for
connections to a copper 10/100/1000 module port on the switch module, regardless of the type of device
on the other end of the connection.
The auto-MDIX feature is enabled by default.
Step 2 Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on
when both the switch module and the connected device have established link.
The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for
loops. This takes about 30 seconds, and then the port LED turns green. If the port LED does not turn on,
the device at the other end might not be turned on, or there might be a cable problem or a problem with
the adapter installed in the attached device. See Chapter 3, “Troubleshooting,” for solutions to cabling
problems.
Step 3 Reconfigure and reboot the connected device if necessary.
Step 4 Repeat Steps 1 through 3 to connect each device.
Connecting to SFP Modules
This section describes how to connect to SFP modules. For instructions on how to connect to fiber-optic
SFP modules, see the “Connecting to Fiber-Optic SFP Modules” section.
For instructions about how to install or remove an SFP module, see the “Installing and Removing SFP
Modules” section on page 2-15.
Connecting to Fiber-Optic SFP Modules
Follow these steps to connect a fiber-optic cable to an SFP module:
Caution Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable
until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables
from contamination and ambient light.
Before connecting to the SFP module, be sure that you understand the port and cabling stipulations in
the “Installation Guidelines” section on page 2-3 and in the “SFP Module Slots” section on page 1-4.
See Appendix B, “Connector and Cable Specifications” for information about the LC on the
SFP module.
Step 1 Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.
Step 2 Insert one end of the fiber-optic cable into the SFP module port (see Figure 2-14).
Step 3 Insert the other cable end into a fiber-optic receptacle on a target device.

Step 4 Observe the port status LED.
The LED turns green when the switch module and the target device have an established link.
The LED turns amber while the STP discovers the network topology and searches for loops. This process
takes about 30 seconds, and then the port LED turns green.
If the LED is off, the target device might not be turned on, there might be a cable problem, or there might
be a problem with the adapter installed in the target device. See Chapter 3, “Troubleshooting,” for
solutions to cabling problems.

Step 5 If necessary, reconfigure and restart the switch module or target device.
Where to Go Next
If the default configuration is satisfactory, the switch module does not need further configuration. You
can use any of these management options to change the default configuration:
•Using the Device Manager
Access the device manager through a web browser from anywhere in your network. Follow
these steps:
a. Launch a web browser on your PC or workstation.
b. Enter the switch module IP address in the web browser, and press Enter. The device manager
page appears.
c. Use the device manager to perform basic switch module configuration and monitoring. Refer to
the device manager online help for more information.
•Using the Command-Line Interface
The switch module CLI is based on Cisco IOS software and enhanced to support desktop-switching
features. You can fully configure and monitor the switch module from the CLI. You can access the
CLI either by connecting your management station directly to the switch module console port or by
using Telnet from a remote management station. Refer to the switch module command reference on
Cisco.com for more information.
•Using SNMP
You can use SNMP management applications such as CiscoWorks Small Network Management
Solution (SNMS) to configure and manage the switch module. You also can manage it from an
SNMP-compatible workstation that is running platforms such as HP OpenView or SunNet Manager.
