Catalyst Switch Module Descriptions

These sections describe the switch modules:

•Catalyst Switch Module 3110G and 3110X

•Catalyst Switch Module 3012

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 blade enclosure management module through 100BASE-T Ethernet links. You can manage the switch modules through the IBM advanced Management Module (aMM) on a management network that is isolated from other switch traffic. You can also manage the switch module through the console port on the switch module front panel or through any of the external uplink ports.

Catalyst Switch Module 3110G and 3110X

The Catalyst Switch Module 3110G and 3110X are stackable, 12- to 18-Gigabit Ethernet port, Layer 3 switch modules. The number of ports depends on the type of switch module. Up to 14 of the Gigabit Ethernet ports are internal 1000BASE-X downlink ports that connect to the blade enclosure. Figure 2 shows the two switch modules, and Table 1 describes the switch module ports.

3 Installing the Switch Module

This section covers switch module installation. The illustrations in this section show the Catalyst Switch Module 3110G as an example. The instructions are the same for the Catalyst Switch Module 3110X and 3012.

Installation Guidelines

Consider these guidelines before you install the switch module:

•Fill any unoccupied interconnect bays or any unoccupied power module bays in the blade enclosure with filler modules.

•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 4, if possible.

See the IBM blade enclosure documentation for more information about the specific enclosure model, the interconnect bay options, and the port mapping between the blade enclosure and the switch modules. Also see the blade enclosure compatibility table in the switch module release notes on Cisco.com.

•For switch stacks, you should first install and configure the switch module that will be the stack master before installing any additional switch modules. See the "Creating Switch Stacks" section for more information.

•Review and become familiar with the safety guidelines in the Regulatory Compliance and Safety Information for the Cisco Catalyst Switch Module 3110G, 3110X, and 3012 for IBM BladeCenter on the documentation CD.

•Review and become familiar with the safety guidelines, and the temperature, power, and grounding requirements specified in the IBM blade enclosure installation and user's guide.

See "Creating Switch Stacks" for more information about creating switch stacks.

5 Managing the Switch Module

After you complete the initial switch module configuration, use the aMM, the CLI, the switch module device manager, or the other management options described in this section for further configuration.

Blade Enclosure Advanced Management Module

For standalone switch modules, you can use the aMM to configure and manage the switch module. See the IBM BladeCenter Advanced Management Module User's Guide for more information. For stacked switch modules, use the CLI, the switch device manager, or the Cisco Network Assistant to configure and manage the switch stack.

Command-Line Interface

You can enter Cisco IOS commands and parameters through the CLI. You can access the CLI by connecting your management station directly to the switch module console port or by using Telnet from a remote management station.

To connect to the switch module console port, follow these steps:

1. Connect the supplied USB-to-DB-9 adapter cable to the serial port on the PC. Connect the USB 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, no parity, 1 stop bit, and no flow control.

4. Use the CLI to enter commands to configure and manage the switch module and switch stacks. See the software configuration guide and the command reference on Cisco.com for more information.

Switch Module Device Manager

You can use the device manager (Figure 8) that is in the switch module memory to manage a standalone switch module or a switch stack. 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.

3. Use the device manager to perform basic switch module configuration and monitoring. Refer to the device manager online help for more information.

Cisco Network Assistant

Cisco Network Assistant is a software program that you download from Cisco.com and run on your PC. It offers advanced options for configuring and monitoring multiple devices, including switch modules, switch clusters, routers, and access points. Network Assistant is free—there is no charge to download, install, or use it.

Follow these steps:

1. Go to this web address: http://www.cisco.com/go/NetworkAssistant.

You must be a registered Cisco.com user, but you need no other access privileges.

2. Find the Network Assistant installer.

3. Download the Network Assistant installer, and run it. (You can run it directly from the web if your browser offers this choice.)

4. When you run the installer, follow the displayed instructions. In the final panel, click Finish to complete the Network Assistant installation.

Refer to the Network Assistant online help and the getting started guide for more information.

Other Management Options

You can use SNMP management applications such as CiscoWorks Small Network Management Solution (SNMS) and IBM Director to configure and manage the switch module.

6 Creating Switch Stacks

This section is only for the Catalyst Switch Module 3110G and 3110X and is optional.

A switch stack is a set of up to nine stacking-capable switch modules that are connected through their StackWise Plus ports. One switch module controls the operation of the stack and is called the stack master. The stack master and the other switch modules in the stack are stack members. Layer 2 and Layer 3 protocols present the entire switch stack as a single entity to the network. When switch modules are not stacked, each acts as a standalone switch module.

---

Caution The Catalyst Switch Module 3110G and 3110X do not support switch stacks with other types of blade switches as members. Combining the switch module with other types of blade switches in a switch stack might cause the switch module to work improperly or to fail.

---

Stacking Guidelines

Before you connect the switch modules in a stack, observe these stacking guidelines:

•You should install the stack master switch module and run the initial setup program on that switch module before you connect the StackWise Plus cables to other stack members. We recommend that you assign the highest priority value to the switch module that you prefer to be the stack master. This ensures that the switch module is re-elected as stack master if a re-election occurs. As you add new switch modules to the stack, they automatically become stack members.

To assign a priority value after you have installed and initially configured the first switch module, see the "Designating the Switch Stack Master" section.

•When you connect the StackWise Plus cables and create a stack, only the status of the stack master Fa0 interface appears in the switch module configuration, and it will show that the port is shut down while in stack mode.

•You can stack a combination of up to nine switch modules. You can stack only the Catalyst Switch Modules 3110G and 3110X; other blade switches are not supported.

•For conditions that might cause a stack master re-election and for general concepts and procedures to manage switch stacks, see the "Managing Switch Stacks" chapter in the switch module software configuration guide on Cisco.com.

•Before connecting, verify the StackWise Plus cable length. Depending on your configuration, you might need different sized cables. If you do not specify the length of the StackWise Plus cable when you order your product, the 1-meter cable is supplied. If you need the 0.5-meter cable or the 3-meter cable, you can order these StackWise Plus cables from your supplier:

–CAB-STK-E-0.5M= (0.5-meter cable)

–CAB-STK-E-1M= (1-meter cable)

–CAB-STK-E-3M= (3-meter cable)

Connecting a Switch Stack

Follow these steps:

---

Step 1 Install the member switch modules if you have not already done so.

Step 2 Remove the dust covers from the StackWise Plus cables, and store them for future use.

Step 3 Verify that cables are aligned as shown in Figure 11. (The cables are keyed for correct insertion.)

Figure 11 Connecting the StackWise Plus Cables

Step 4 Insert the cable into the StackWise Plus port on the front panel of the switch module. Insert the other end of the cable into the connector of the other switch module.

Always use a Cisco-approved StackWise Plus cable to connect the switch modules.

---

Caution The new stack-member switch module restarts when you connect the StackWise Plus cables.

---

Step 5 Configure the member switch modules through the master switch by using the CLI through the console port of any stack member.

---

To remove the StackWise Plus cables, grasp the tab on the cable connector, and gently pull straight out. When you remove the StackWise Plus cables, replace the dust covers to protect them from dust.

---

Caution Removing and installing the StackWise Plus cable can shorten its useful life. Do not remove and insert the cable more often than is absolutely necessary.

---

Switch Stack Cabling Example

Figure 12 shows a single blade enclosure with two switch modules that create one stack. The stack uses the 1-meter StackWise Plus cables to make redundant connections between two switch modules. Other types of configurations are possible if you stack no more than nine switch modules. Although the StackWise Plus ports are numbered (1 and 2), you do not need to make specific port connections between switch modules.

For more stacking configuration examples, see the switch module hardware installation guide and the software configuration guide on Cisco.com.

Figure 12 Switch Stack Cabling Example

7 Connecting Devices

This section describes how to connect to the fixed switch module ports and to the 10-Gigabit Ethernet module slot.

Connect to 10/100/1000 Ports

The 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 UTP cable. The 10BASE-T traffic can use Category 3 or Category 4 cable.

The autonegotiation feature is enabled by default on the switch module. At this setting, the switch module ports configure themselves to operate at the speed of attached devices. If the attached device does not support autonegotiation, you can explicitly set the switch module port speed and the duplex parameters. To maximize performance, either allow the ports to autonegotiate both speed and duplex, or set the port speed and duplex parameters on both ends of the connection.

For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default on the switch module. With auto-MDIX enabled, the switch module detects the required cable type for copper Ethernet connections and configures the interface accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a switch module 10/100/1000 Ethernet port, regardless of the type of device on the other end of the connection.

For more information about enabling or disabling autonegotiation and auto-MDIX, see the switch module software configuration guide or the command reference on Cisco.com.

Install and Connect to Devices in the 10-Gigabit Ethernet Slot

The switch module 10-Gigabit Ethernet module slot is used for connections to other switches and routers. The module slot operates in full-duplex mode and uses the hot-swappable Cisco X2 transceiver module. The X2 transceiver module has SC connectors to connect to multimode fiber (MMF) and single-mode fiber (SMF) cables.

Use only Cisco X2 transceiver modules with the switch module. Each Cisco 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 module meets the requirements for the switch module.

Verify Port Connectivity

After you connect a device to a switch module port, the port LED is off while the switch module establishes a link. This process takes about 30 seconds. Then the LED turns green when the switch module and the attached device have an established link. If the LED is off, the device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the device. See the "In Case of Difficulty" section for more information.

8 In Case of Difficulty

If you experience difficulty, help is available in this section and also on Cisco.com. You can access the Cisco Technical Support and Documentation website for a list of known hardware problems and extensive troubleshooting documentation at:

http://www.cisco.com/en/US/support/index.html

For more information about the IBM blade enclosure, see the IBM blade enclosure website at: http://www-03.ibm.com/systems/bladecenter/

Troubleshooting Switch Module Setup

Review this section if you are having trouble running the initial setup procedures:

•Did you try to access the switch module through the aMM before installing the switch module in the blade enclosure?	If yes, install the switch module as described in the "Installing the Switch Module" section.
•Did you verify that POST successfully ran on the switch module before accessing the switch through the aMM?	If not, make sure that the switch module System power LED is green before using the aMM to access the switch module.
•Did you try to access the switch module through the aMM after connecting the StackWise Plus cables?	If yes, disconnect the StackWise Plus cables. Remove the switch module, and then reinstall the switch module. Follow the procedures described in the "Configuring the Switch Module" section.
•When accessing the switch module device manager, did you enter the wrong address in the browser, or is there an error message?	If yes, re-enter the switch module IP address in the browser, and press Enter.

Resetting the Switch Module

For a standalone switch module, you can perform these functions by using the aMM web interface:

•Reboot the switch module

•Restore factory defaults

•Set or reset the IP address, netmask, and default gateway

•Enable or disable external ports

•Enable or disable management through the external ports

•Change configuration

•Change or update firmware

For a switch stack, you can use the CLI to perform the same functions. For more information, see the switch module software configuration guide and command reference on Cisco.com.

Using the Mode Button to Reset the Switch Module

You can use the Mode button to reset a standalone switch module.

---

Caution For a standalone switch module, resetting the switch module deletes the configuration and reboots the switch module.

---

For a standalone switch module, use a small pointed object to press and hold the Mode button on the switch module front panel. The switch module LEDs begin blinking after about 3 seconds. Continue holding down the Mode button. The LEDs stop blinking after 7 more seconds, and then the switch module reboots.

The switch module is now unconfigured. You can enter the switch module IP information by following the procedures described in the "Configuring the Switch Module" section.

For switch stacks, pressing and holding the Mode button on a member switch module causes the stack to reboot. It does not remove the configuration from any member switch.
