This feature is called “hot-swapping.” Caution: Be sure to remove cables from all ports on the module, or disable all the ports through the management interface, prior to hot-swapping.
Chapter 2 Planning a Network with EtherSpeedII Switch Modules Installing the EtherSpeedII 10/100BASE-T or EtherSpeedII 100BASE-FX switch modules in a network can significantly improve LAN performance. This chapter provides information to help you plan a network that uses either or both of these modules.
Using the Centillion EtherSpeedII Switch Modules To connect the ports on the patch panel to another Ethernet switch or an Ethernet hub, follow these guidelines: • Personal computers (PCs) and servers typically have network interface cards (NICs) that are configured as MDI connections. To connect these devices, use a straight-through cable. • Hubs and other switches typically have connectors that are configured as MDI-X.
Planning a Network with EtherSpeedII Switch Modules This section describes the following Ethernet switching applications: • • • • • • Dedicated ports for servers (page 2-4) Replacement for a bridge port (page 2-5) Desktop switch with ATM uplinks in a wiring closet (page 2-6) Segment switch in a wiring closet with ATM uplinks to a network center switch (page 2-7) Desktop switch and frame-to-cell converter (page 2-8) MultiLink Trunking (page 2-9) ATM MDA MCP module with fiber MDAs EtherSpeedII modules Cen
Using the Centillion EtherSpeedII Switch Modules Giving a Server a Dedicated Port Moving a server from a 10 Mb/s shared-media connection to a dedicated port on the EtherSpeedII 10/100BASE-T switch module or the EtherSpeedII 100BASE-FX switch module improves server response time and increases throughput capacity. For even higher performance, upgrade the server to 100 Mb/ s and the switch modules can autonegotiate for 100 Mb/s.
Planning a Network with EtherSpeedII Switch Modules Replacing a Bridge Using a switch instead of a bridge in the network can increase the aggregate network bandwidth. The “After” example in Figure 2-3 shows one server connected to a dedicated 10BASE-T port. It also shows the other server and additional clients attached using dedicated 100BASE-TX connections. This network configuration allows you to have switched 10 Mb/s Ethernet along with segmented 10 Mb/s Ethernet to conserve ports.
Using the Centillion EtherSpeedII Switch Modules Desktop Switch with ATM Uplinks In the example shown in Figure 2-4, the EtherSpeedII 10/100BASE-T switch module provides 20 RJ-45 switched Ethernet (10/100 Mb/s) ports to connect to desktops, with redundant high-speed ATM OC-3c and OC-12c ports to connect to an ATM backbone. This network configuration can support small to large wiring closets. Figure 2-4 also illustrates a sample network providing ATM uplinks to a Centillion 50/100 chassis.
Planning a Network with EtherSpeedII Switch Modules Segment Switch in an Enterprise Network To achieve a gradual transition from shared media to switched networks, you can use the EtherSpeedII 10/100BASE-T switch module or the EtherSpeedII 100BASE-FX switch module to aggregate traffic from stations connected to one or more hubs. Figure 2-5 shows such a network with switches used to connect shared-media hubs to a backbone switch.
Using the Centillion EtherSpeedII Switch Modules Desktop Switch and Frame-to-Cell Converter For wiring closets with higher densities and lower bandwidth requirements, you can use the EtherSpeedII 10/100BASE-T switch module to aggregate traffic from other stackable switch products such as the BayStack™ 301 and BayStack 350T switches (providing frame switching) to an ATM backbone (providing cell switching).
Planning a Network with EtherSpeedII Switch Modules MultiLink Trunking MultiLink Trunking (MLT) allows up to four physical connections for the same media type and speed to be grouped and treated as a single logical link. MLT improves performance between two switches or between a switch and a server. Ports in a single MLT group can span multiple modules. MLT allows data to be carried over multiple 100 Mb/s full-duplex links connected to the same device, thus improving performance.
Using the Centillion EtherSpeedII Switch Modules Default Port Configuration The EtherSpeedII 10/100BASE-T switch module is shipped preconfigured with the factory default settings listed in Table 2-1. Table 2-1.
Planning a Network with EtherSpeedII Switch Modules Predefined SpeedView Configurations SpeedView offers several predefined configurations. You may choose one of these without configuring individual ports. Predefined configurations are available for the following applications: • All transparent switching with no IEEE 802.1d Spanning Tree support • All transparent switching with IEEE 802.
Chapter 3 Installing the EtherSpeedII Switch Modules This chapter explains how to install and connect the EtherSpeedII 10/100BASE-T switch module or the EtherSpeedII 100BASE-FX switch module, and includes the following information and procedures: • Preparing for installation (this page) • Installing a switch module (page 3-2) • Checking LEDs to verify the installation (page 3-6) • Connecting cables to Model # ports (page 3-8) • Removing a switch module (page 3-8) Preparing for Installation Before
Using the Centillion EtherSpeedII Switch Modules Safety Always follow static electricity and other safety guidelines when handling EtherSpeedII switch modules. Caution: Centillion equipment uses electronic components that are sensitive to static electricity. Static discharge from your clothing or other fixtures around you can cause damage. Take all possible precautions to prevent static discharge damage when working with printed circuit boards.
Installing the EtherSpeedII Switch Modules To install and secure the module in the chassis: 1. Remove the filler panel. Using the medium flat-tip screwdriver, loosen the two captive retaining screws on the filler panel until they pop free of the chassis. Rotate the left and right inserter/extractor levers away from the center of the filler panel to their protruding positions and remove the filler panel (Figure 3-1). 6463 Figure 3-1. 2.
Using the Centillion EtherSpeedII Switch Modules 3. Align the left and right edges of the module in the guides on each side of the slot (Figure 3-3). 6465 Figure 3-3. 4. Slot Module Guides Slide the module into the chassis until you feel it engage the backplane. The inserter/extractor levers should still be protruding and in contact with the front of the chassis. Do not push the module all the way into the chassis (Figure 3-4). 6466 Figure 3-4.
Installing the EtherSpeedII Switch Modules 5. To seat the module onto the backplane, push the inserter/extractor levers inward toward the module (Figure 3-5). 6537FA Figure 3-5. Seating the Module When the front panel of the module is flush with the front of the chassis, the module backplane connectors are properly seated. 6. Use the flat-tip screwdriver to tighten the captive retaining screw at each end of the module front panel.
Using the Centillion EtherSpeedII Switch Modules Checking LEDs on the Switch Modules If an EtherSpeedII 10/100BASE-T switch module is installed correctly, upon power-up, all of the LEDs on the front panel light in a sequential pattern. As you connect devices to the switch module’s ports, watch the LEDs on the front panel (Figure 3-6). An established link displays the following LED color sequence: • The LINK LED lights green for each port showing link status.
Installing the EtherSpeedII Switch Modules If an EtherSpeedII 100BASE-FX switch module is installed correctly, upon power-up, all of the LEDs on the front panel light in a sequential pattern. As you connect devices to the switch module’s ports, watch the LEDs on the front panel (Figure 3-7). • The LINK LED lights green for each port for which a link is established. • The ERROR LED lights amber if a line error is detected.
Using the Centillion EtherSpeedII Switch Modules Making 10/100 Mb/s Cable Connections The 10/100 Mb/s jacks on the EtherSpeedII 10/100BASE-T switch module accept standard UTP or STP cable connections. To connect network devices to the 10/100 Mb/s ports on the switch module, follow these guidelines: • Use Category 3 or 5 UTP cable or STP cable with RJ-45 connectors for the ports on the switch module. • Use straight-through cables to connect the network interface card (NIC) in a PC workstation or server.
Installing the EtherSpeedII Switch Modules 2. Wait 45 seconds. Waiting allows the system software to process the requests to disable the ports. Caution: If you remove a module without waiting 45 seconds after disabling the ports, you must power cycle the Centillion 50/100 chassis. When you turn off the power on the chassis, you must wait 15 to 20 seconds before turning the power back on. The switch modules begin switching an additional 15 to 20 seconds after power is resumed. 3.
Using the Centillion EtherSpeedII Switch Modules 5. Slide the switch module out of the chassis (Figure 3-9). Hold the front panel with one hand while you support the bottom of the switch module with the other hand. 6471 Figure 3-9. Removing the Module from the Centillion 50/100 Chassis 6. Place the switch module on an antistatic mat until you are ready to put it back into the chassis. 7. If you are not installing another switch module of the same model, install a filler panel over the empty slot.

Using the Centillion EtherSpeedII Switch Modules EtherSpeedII Switch Module Startup Failure Symptom: All LEDs are solidly lit (do not blink) on the switch module. To resolve the problem: 1. Ensure that an MCP module is present and operational with the appropriate version of software. • The EtherSpeedII 10/100BASE-T switch module requires version 4.1.2 software or greater. • The EtherSpeedII 100BASE-FX switch module requires version 4.2.1 software or greater. 2.
Troubleshooting Port Connection Problems Symptom: The LED on a switch port is off. If an LED does not light when traffic is present, there may be a port connection problem. To resolve the problem: 1. Verify whether or not the port is enabled, using SpeedView or the CLI. a. From the Map window in SpeedView, choose Switch and then choose Configure. When the configuration information has been downloaded to the management station, check the port state. The port state should be either enabled or disabled. b.
Using the Centillion EtherSpeedII Switch Modules 3. Verify that the port is transmitting and receiving data frames. a. Check the green RJ-45 LED, which indicates a data exchange. Refer to Appendix C, “LED Displays on the EtherSpeedII Switch Modules,” for additional information. b. From the Map window in SpeedView, choose Statistics. When the statistics information is displayed at the management station, verify that the octet counts for transmit and receive are incrementing.

Appendix B Cables and Connectors This appendix provides general information about 10BASE-T and 100BASE-TX cabling and connections. UTP Cable Length Limitations All 10BASE-T/100BASE-T ports on EtherSpeedII switch modules support the maximum lengths for twisted pair cable that are specified in the IEEE 802.3 10BASE-T/100BASE-TX Ethernet specification. This specification defines the maximum segment length in terms of the performance characteristics of the cable media, which can vary according to cable type.
Using the Centillion EtherSpeedII Switch Modules UTP Cabling A 10BASE-T/100BASE-TX connection between two ports requires two twisted pairs. The transmit data (TD) pair carries data out from the port transmitter. The receive data (RD) pair carries data in to the port receiver.
Cables and Connectors The switch module receives data on pins 1 and 2 and transmits its data on pins 3 and 6. The host module ports implement this MDI standard crossover internally and are called MDI-X (the X for crossover), as shown in Figure B-1. All EtherSpeedII switch module 10BASE-T ports are MDI-X standard.
