Statement 171 Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206 Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
Chapter 2 Switch Module Installation Preparing for Installation Installation Guidelines Note This product is not intended to be connected directly or indirectly by any means whatsoever to interfaces of public telecommunications networks. 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.
Chapter 2 Switch Module Installation Installing the Switch Module 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.
Chapter 2 Switch Module Installation Installing 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 C O N S O LM EO D E ! M B R M S T LNK 15 ACT LNK 16 ACT LNK 17 ACT LNK 1 STA CK 2 Step 8 201897 18 ACT 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.
Chapter 2 Switch Module Installation Creating Switch Stacks 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.
Chapter 2 Switch Module Installation Creating Switch Stacks 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.
Chapter 2 Switch Module Installation Creating Switch Stacks 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.
Chapter 2 Switch Module Installation Creating Switch Stacks Figure 2-5 is an example of a recommended configuration in which eight switch modules create a switch stack in eight blade enclosures.
Chapter 2 Switch Module Installation Creating Switch Stacks Figure 2-6 shows an example of a recommended configuration in which eight switch modules create two separate switch stacks in eight blade enclosures. This configuration provides redundant connections.
Chapter 2 Switch Module Installation Installing Devices in the 10-Gigabit Ethernet Slot 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.
Chapter 2 Switch Module Installation Installing Devices in the 10-Gigabit Ethernet Slot Caution 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.
Chapter 2 Switch Module Installation Connecting Devices to the Ethernet Ports 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. Caution Category 5e and Category 6 cables can store high levels of static electricity.
