Cisco Gigabit Ethernet Switch Module Description
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 server. 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 Mbps if used as RJ-45 ports and
operate at 1000 Mbps if small form-factor pluggable (SFP) fiber-optic modules are installed. See
Table 1 for more detailed descriptions of the switch module ports.
Figure 1 shows the switch module.
Figure 1 The Catalyst Blade Switch 3020 for HP
The switch module is managed through the RS-232 console port that uses an RJ-45 connector in the
switch module front-panel.

The blade server includes a chassis management module, the Onboard Administrator. Each switch
module connects internally to the Onboard Administrator through 100BASE-T Ethernet links. You
can manage the switch modules through the Onboard Administrator on a management network that
is isolated from other switch traffic. You can also manage the switch module through any of the
external uplink ports.
Table 1 describes the switch module ports. Each external port has an associated LED.
The switch module is powered from the blade server backplane, and temperature management is
provided by the blade server. There is no fan on the switch module.

Ports 1 to 16 Internal Gigabit Ethernet 1000BASE-X downlink 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 switch module 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 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.
4 Installing the Switch Module in the Blade Server
Before you install the switch module in the blade server, consider these points:
•Review and become familiar with the safety guidelines in the Regulatory Compliance and Safety
Information for the Cisco Catalyst Blade Switch 3020 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 server.

7
Follow these steps to install the switch module in the blade server:
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 server 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 3.)

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 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 14 for how to set up the switch module if the IP address is being assigned
dynamically.
5 Running Express Setup
You need to supply this equipment to run Express Setup:
•PC
•Ethernet (Category 5) straight-through cable (as shown)

10
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.

11
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 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.
If the switch module fails POST, the system LED turns amber. If the POST fails, see the “In
Case of Difficulty” section on page 21 to determine a course of action. POST errors are
usually fatal. Call Cisco Systems immediately if your switch module fails POST.

12
Step 4 Press and hold the Mode button until the four LEDs next to the Mode button turn green. This
takes approximately 3 seconds.
Step 5 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. For more information, see the “Resetting the Switch Module” section on
page 23.
Step 6 Connect a straight-through Category 5 Ethernet cable (not provided) to any Ethernet port on
the switch module front panel and to the Ethernet port on the PC. (See Figure 5.)

Step 9 Enter the IP address 10.0.0.1 and press Enter.
The Express Setup home page appears.
Step 10 Go to “Completing the Express Setup Fields” section on page 17 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.

15
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 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.
Step 1 Wait for the switch module to complete POST. It might take several minutes for the switch
module to complete POST.
Step 2 Verify that POST has completed by confirming that the system and 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 21 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.
Step 4 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.
Step 5 Click Enclosure > 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.

16
Step 6 Click the IP address hyperlink for the switch module from the Management URL column to
open a new browser window. The Device Manager window for the switch module opens.
Step 7 On the left side of the Device Manager GUI, click Configuration > Express Setup.

17
The Express Setup page appears.
Step 8 Go to “Completing the Express Setup Fields” section on page 17 to finish setting up the switch
module 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.

18
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.
– 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 switches 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 “Managing the Switch Module” section on page 19 for information about configuring
and managing the switch module.
If you need to rerun Express Setup, see the “Resetting the Switch Module” section on page 23.
To install additional switch modules, repeat the steps in the “Installing the Switch Module in the Blade
Server” section on page 6 through the “Running Express Setup” section on page 9.

19
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.
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:
1. Launch a web browser on your PC or workstation.
2. Enter the switch module IP address in the web browser, and press Enter. The device manager page
appears.

20
3. Use the device manager to perform basic switch module configuration and monitoring. Refer to
the device manager online help for more information.
4. For more advanced configuration, download and run the Cisco Network Assistant, which is
described in the next section.
Command-Line Interface
You can enter Cisco IOS commands and parameters through the CLI. Access the CLI either by
connecting your PC directly to the switch module console port or through a Telnet session from a
remote PC or workstation.
Follow these steps:
1. Connect the supplied RJ-45-to DB-9 adapter cable to the standard 9-pin serial port on the PC.
Connect the other end of the cable to the console port on the switch module.
2. Start a terminal-emulation program on the PC.
3. Configure the PC terminal emulation software for:
– 9600 baud
– 8 data bits
