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 Table 1 for more detailed descriptions of the switch module ports.

Figure 1 shows the switch module.

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.

Port Description

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 precedenceif both SFP module and copperEthernet interface types are in link-up state.You can also specifically configureeachport 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.

Internal 100BASE-T Ethernet port

Console port RJ-45 switch module management port.

This port (fa0) is used only for switch module management traffic,not for data traffic. It is connected to the Onboard Administrator through the blade server backplane connector.

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.

Onboard Administrator module

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 firstswitchmodule 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 forinformation on the port mapping betweenblade 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

Caution To prevent electrostatic-discharge (ESD) damage when installing switch modules, follow

Note When you install a switch module, you do not need to power down the blade server.

Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

your normal board and component handling procedures.

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.)

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)

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.

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.
