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.
