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.
•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.
•The orange release latch on the switch module means that it is hot-swappable. To maintain proper system cooling, you must replace a hot-swap switch module within 1 minute of removal.
•Verify that clearance to the switch-module front panel is such that
–Front-panel indicators can be easily read.
–Access to ports is sufficient for unrestricted cabling.
–The X2-10GB-CX4 transceiver-module minimum-bend radius and connector length is met. See the X2 transceiver module documentation for more information.
•Confirm that cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.
•For copper connections on Ethernet ports, cable lengths from the switch module to connected devices can be up to 328 feet (100 meters).
•For cable requirements for X2 module connections, see the "Cable and Adapter Specifications" section on page B-2. Each port must match the wave-length specifications on the other end of the cable, and the cable must not exceed the required cable length.
•Operating environment is within the ranges listed in Appendix A, "Technical Specifications."
•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.

Installing the Switch Module
This section covers switch module installation. The illustrations in this section show the Catalyst Switch Module 3110G. The instructions are the same for the Catalyst Switch Module 3110X and 3012.
Follow these steps:
Step 1 Remove the acoustic attenuation module, if one is installed, from the rear of the blade enclosure.
Step 2 Select the blade enclosure bay in which to install the switch module (Figure 2-1).
Note Figure 2-1 shows the IBM BC-H blade enclosure as an example. Your blade enclosure might look different.
Figure 2-1 Blade Enclosure Rear-Panel View
I/O module bay 1
I/O module bay 3
I/O module bay 2
I/O module bay 4
Step 3 Remove the filler module from the selected bay. Store the filler module for future use.
Step 4 If you have not already done so, touch the static-protective package that contains the switch module to any unpainted metal surface of the blade enclosure or any unpainted metal surface on any other grounded rack component for at least 2 seconds.
Step 5 Remove the switch module from its static-protective package.
Step 6 Move the switch module release latch to the open position (perpendicular to the switch module).
Step 7 Slide the switch module into the bay until it stops (Figure 2-2).
Figure 2-2 Installing the Switch Module
Step 8 Move the switch module release latch to the closed position. After you insert and lock the switch module, it turns on, and the power-on self-test (POST) runs to verify that the switch module is operating correctly.
The system power LED blinks green while POST is running and then turns solid green when POST is finished.
Step 9 Confirm that the switch module system power LED is green. See the "Switch Module LEDs" section on page 1-5 for more information about the switch module LEDs.
Step 10 Replace the acoustic-attenuation module, if applicable.
To remove the switch module, reverse the installation procedure. Place either another switch module or a filler module in the blade enclosure bay within 1 minute of removal.
After Installing the Switch Module
After the switch module is installed, you might need to:
•Configure the switch module with the initial configuration. For instructions, see the switch module getting started guide on the documentation CD and also on Cisco.com.
•Connect the StackWise Plus cables to create a switch stack. See the "Creating Switch Stacks" section for more information.
•Connect to the switch-module ports. See the "Installing Devices in the 10-Gigabit Ethernet Slot" section and the "Connecting Devices to the Ethernet Ports" section.
Creating Switch Stacks
This section is only for 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.
The Catalyst Switch Module 3110G and 3110X do not support switch stacks with other types of blades 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.
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.
•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 shows 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.
•Although the StackWise Plus ports are numbered (1 and 2), you do not need to make specific port connections between switch modules.
•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 2-3. (The cables are keyed for correct insertion.)
Figure 2-3 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.
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 module 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.
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 Examples
Figure 2-4 is an example of a recommended configuration in which two switch modules create a switch stack in a single blade enclosure.

Installing Devices in the 10-Gigabit Ethernet Slot
This section describes how to install and remove X2 transceiver modules.
Use only Cisco X2 transceiver modules with the switch modules. 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.
For more information about installing, removing, cabling, and troubleshooting X2 transceiver modules, see the module documentation that shipped with your device. For module cable specifications, see Appendix B, "Connector and Cable Specifications."
Installing an X2 Transceiver Module
When installing an X2 transceiver module, observe these general precautions:
•Do not remove the module slot cover from the 10-Gigabit Ethernet slot until you are ready to install an X2 transceiver. Either a module or the module slot cover must be installed in the slot at all times.
•Do not remove the dust plugs from the fiber-optic X2 transceiver modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.
•Removing and installing an X2 module can shorten its useful life. Do not remove and insert any X2 module more often than is absolutely necessary.
•To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch module and other devices.
To install an X2 transceiver module, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2 Remove the module from the protective packaging.
Step 3 Remove the 10-Gigabit Ethernet module slot cover and save.
Step 4 Align the transceiver module in the module slot (Figure 2-7).
Verify the correct orientation of your module before inserting it into the slot. Incorrect insertion can damage the module.
Step 5 Slide the transceiver module into the opening until the back of the module faceplate is flush with the switch module faceplate.
Figure 2-7 Installing an X2 Transceiver Module
Removing a Module
To remove an X2 transceiver module, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2 Disconnect the cables from the module. For fiber-optic modules, install the optical bore dust plugs.
Step 3 Carefully pull on the X2 module sleeve to disengage it from the slot. Grasp the edges of the module, and carefully slide it out of the slot.
Step 4 Reinstall a replacement module or the module slot cover in the 10-Gigabit Ethernet slot.
Step 5 Place the module in an antistatic bag or other protective environment.
Connecting Devices to the Ethernet 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.
Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables to a suitable and safe earth ground before connecting them to the switch module or other devices.
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 device. If the attached device does not support autonegotiation, you can explicitly set the switch-module port speed and duplex parameters. To maximize performance, either let the ports 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.
See the switch module software configuration guide and the command reference on Cisco.com for more information about enabling or disabling autonegotiation and auto-MDIX.
If auto-MDIX is disabled, use the guidelines in Table 2-1 to select the correct cable for connecting the switch-module 10/100/1000 Ethernet ports to other devices. See the "Cable and Adapter Specifications" section on page B-2 for cable-pinout descriptions.
