Cisco Switch Module Descriptions
These sections describe the switch modules:
•Cisco Catalyst Blade Switch 3120 for HP, page 4
•Cisco Catalyst Blade Switch 3020 for HP, page 6
The switch module is powered from the blade enclosure backplane. The switch module does not have
a fan. The blade enclosure provides temperature management.
The switch module connects internally to the management module through 100BASE-T Ethernet links.
You can manage the switch modules through the HP Onboard Administrator management module on
a management network that is isolated from other switch traffic. You can manage the switch module
through the RS-232 console port that uses an RJ-45 connector in the switch module front-panel. You
can also manage the switch module through any of the external uplink ports.
Cisco Catalyst Blade Switch 3120 for HP
The Cisco Catalyst Blade Switch 3120 for HP is a stackable, 25 to 27 Gigabit Ethernet port, Layer 3
switch module. The number of ports depends on the type of module installed in ports 19 to 22.
See Table 1 for a description of the switch module ports. See the release notes and the software
configuration guide for information about supported Layer 3 features. See the hardware installation
guide for detailed information about stacking the switch.
The Cisco Catalyst Blade Switch 3120 for HP has a 3120G and a 3120X model. Both are
stacking-capable. The initial setup procedure for both models is the same. For more information about
the features of each model, see the hardware installation guide and the software configuration guide
for the switch module.

port has an associated LED.
Cisco Catalyst Blade Switch 3020 for HP
The Cisco Catalyst Blade Switch 3020 for HP is a 24-Gigabit Ethernet port, Layer 2+ switch module.
Sixteen of the Gigabit Ethernet ports are internal 1000BASE-X downlink ports that connect to the
blade enclosure. The other eight Gigabit Ethernet ports are external uplink ports that provide
connections to other switches or routers. Uplink ports operate at 10/100/1000 M/ps if used as
copper-based ports and operate at 1000 M/ps if small form-factor pluggable (SFP) fiber-optic modules
are installed. See Table 2 for more detailed descriptions of the switch module ports.

Ports 17 to 20 and
Ports 17x to 20x
Dual-purpose SFP module/RJ-45 copper Ethernet uplink ports. The SFP module
ports support only Cisco 1000BASE-SX fiber-optic modules.
By default, the switch module dynamically selects the interface type that first
links up. SFP modules have precedence if both SFP module and copper Ethernet
interface types are in link-up state. You can also specifically configure each port
for either copper Ethernet or SFP modules if you do not want to use
autodetection.
The copper Ethernet ports support automatic medium-dependent interface
crossover (auto-MDIX) and autonegotiation.
For information about configuring speed and duplex settings for a
dual-purpose uplink port, see the software configuration guide.
Ports 21x to 22x External 10/100/1000BASE-T copper Gigabit Ethernet uplink ports that
support auto-MDIX and autonegotiation.
Ports 23x to 24x Dual-purpose external/internal 10/100/1000BASE-T copper Gigabit Ethernet
uplink ports. These ports can be configured for internal 1000BASE-X
cross-connection with a corresponding switch module. When ports 23x and
24x are in external operation mode, they support auto-MDIX and
autonegotiation. The default is external operation mode.

Consider these prerequisites before you install the switch module:
•Fill any unoccupied interconnect bays or any unoccupied power module bays in the blade
enclosure 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 enclosure and how they are configured. See the blade enclosure documentation information
about installing and configuring the mezzanine or Ethernet cards.
The interconnect module bays are physically interconnected in pairs through the blade enclosure
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 enclosures
and the switch modules.
4 Installing the Switch Module in the Blade Enclosure
Before you install the switch module in the blade enclosure, consider these points:
•Review and become familiar with the safety guidelines in the Regulatory Compliance and Safety
Information for the Cisco Catalyst Blade Switch 3000 Series for HP that accompanies this guide.
•Review and become familiar with the safety guidelines in the HP BladeSystem enclosure setup and
installation guide.
•Review and become familiar with the temperature, power, and grounding requirements specified
in the HP BladeSystem enclosure setup and installation guide.
Warning Only trained and qualified personnel should be allowed to install, replace, or service
this equipment. Statement 1030
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 blade enclosure.

11
Follow these steps to install the switch module in the blade enclosure. The illustrations in this section
show the Cisco Catalyst Blade Switch 3020 for HP switch module. The instructions are the same for
the Cisco Catalyst Blade Switch 3120 for HP switch module.
Step 1 If you have not already done so, touch the static-protective package that contains the switch
module to an unpainted metal part of the blade enclosure for at least 2 seconds.
Step 2 Remove the switch module from its static-protective package.
Step 3 Remove the interconnect blank from the bay where you plan to install the switch module, if
one is present, and install the switch module. (See Figure 4.)

Step 6 Push the release latch on the front of the switch module to the closed position.
5 Using the Onboard Administrator to Assign an IP Address
to the Switch Module and Running Express Setup
For the switch module to obtain an IP address for the Fa0 interface through the Onboard
Administrator, these conditions must be met:
•The blade enclosure 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 enclosure 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.
After you have installed the switch module (see the “HP Blade System Architecture” section on
page 9), it powers on. The switch module begins the power-on self-test (POST), a series of tests that
runs automatically to ensure that the switch module functions properly.
To set up and initially configure the switch module by using the Cisco IOS CLI, see the “Configuring
the Switch with the CLI-Based Setup Program” section in the hardware installation guide.
Step 1 Wait for the switch module to complete POST. This might take several minutes.
Step 2 Verify that POST has completed by confirming that the system status LEDs remain green.
If the switch module fails POST, the system LED turns amber. If the POST fails, see the “In
Case of Difficulty” section on page 27 to determine a course of action. POST errors are
usually fatal. Call Cisco Systems immediately if your switch module fails POST.
Step 3 Wait approximately 2 minutes for the switch module to get the software image from its flash
memory and begin autoinstallation.
If you already have the Onboard Administrator open through a browser window, go to Step 5.

14
Step 4 Using a PC that is connected to the same network segment as the blade enclosure Onboard
Administrator, access the Onboard Administrator in a browser window. Enter your assigned
user name and password.
Step 5 Choose Enclosure Information > Interconnect Bays to open the Interconnect Bay Summary
window where you can find the assigned IP address of the switch module Fa0 interface in the
Management URL column.
Step 6 Click the IP address hyperlink for the switch module from the Management URL column to
open a new browser window.
Step 7 On the left side of the Onboard Administrator, choose Configuration > Express Setup.
The Express Setup page appears (see Figure 6 and Figure 7). (Close or minimize the Device Manager
Help window.)

15

Figure 7 Express Setup Page for the Cisco Catalyst Blade Switch 3020 for HP
Step 8 Go to “Using Express Setup” to finish setting up the switch module.

16
Using Express Setup
Before you complete the setup program, obtain the default gateway IP address and the switch
password from your system administrator. Depending on whether you are running Express Setup on
a Cisco Catalyst Blade Switch 3120 for HP switch module or a Cisco Catalyst Blade Switch
3020 for HP switch module, you can configure these optional parameters through the Express Setup
program:
•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
•System time, time zone, Daylight Savings Time enable
Follow these steps to finish setting up the switch module. The Onboard Administrator assigns an
IP address and a subnet mask to the management interface (VLAN ID) and to the Ethernet
management port.
Step 1 Enter this information in the Network Settings fields.
– In the Default Gateway field, enter the IP address for the default gateway (router).
– In the Switch Password field, enter your password. 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.
You can enter the Optional Settings information now or enter it later by using the device manager
interface.
Note The fields in the Express Setup page depend on the type of switch module. Not all fields are
available in the Cisco Catalyst Blade Switch 3020 for HP switch module Express Setup page.
Some of the settings are on the Advanced Settings tab for the Cisco Catalyst Blade Switch
3120 for HP switch module (see Figure 8).

17
Figure 8 Advanced Settings Tab
Step 2 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.
Step 3 In the System Date and System Time fields, enter the current date and time, or use the down
arrows to select them.
Step 4 In the Time Zone field, use the down arrow to choose your time zone.
Step 5 Click Enable in the Daylight Savings Time field to enable this feature.
Step 6 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.
Note If you plan to create a switch stack, enable Telnet access so that you can use the CLI
to set this switch to the highest priority. See the “Planning and Creating a Switch
Stack (Only the Cisco Catalyst Blade Switch 3120 for HP)” section on page 23 for
more information about creating a switch stack.
Step 7 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.
Step 8 In the SNMP field, click Enable to enable Simple Network Management Protocol (SNMP).
Enable SNMP only if you plan to manage switches by using CiscoWorks 2000 or another
SNMP-based network-management system.

18
Step 9 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 10 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.
Step 11 Depending on which software license you choose, you can enable IPv6 in the IPv6 Settings
area.
– Click Enable IPv6 to enable it.
– In the Interface column, choose the interface for which you want to set an IPv6 address and
complete the other fields in this table.
Step 12 Click Submit to save your settings, or click Cancel to clear your settings.
You can close this window. If you need to rerun Express Setup, see the “Resetting the Switch
Module” section on page 27.
To install additional switch modules, repeat the steps in the “Installing the Switch Module in the Blade
Enclosure” section on page 10 through the “Using the Onboard Administrator to Assign an IP Address
to the Switch Module and Running Express Setup” section on page 13.
Setting the Installed Switch to be the Stack Master (Only Cisco
Catalyst Blade Switch 3120 for HP Switches)
If you plan to create a switch stack, we recommend that you set the switch module that you first
configured as the stack master. To do this, you must assign the highest priority value to this switch
module. To assign a priority value after you have installed and initially configured the first switch
module, follow these steps:
Step 1 Choose Maintenance > Telnet on the left side of the Onboard Administrator window to
launch a Telnet session.
Step 2 Enter enable.
Step 3 Enter configure terminal.
Step 4 Enter switch 1 priority 15.
Step 5 At the prompt, press Return.

19
Step 6 Enter end.
Step 7 Enter copy running-configuration startup-configuration to save this setting.
Step 8 At the prompt, press Return.
Step 9 To verify that this switch is set as the stack master, enter the show switch user EXEC
command.
For more information about creating switch stacks, see the “Planning and Creating a Switch Stack
(Only the Cisco Catalyst Blade Switch 3120 for HP)” section on page 23.
6 Managing the Switch Module
After you complete Express Setup and install the switch module in your network, use the device
manager or other management options described in this section for further configuration.
Using the Device Manager
The simplest way to manage the switch module is by using the device manager that is in the switch
module memory. This is a web interface that offers quick configuration and monitoring. You can
access the device manager from anywhere in your network through a web browser.
Follow these steps:
Step 1 Launch a web browser on your PC or workstation.
Step 2 Enter the switch module IP address in the web browser, and press Enter. The device manager
page appears (see Figure 10 and Figure 9).
