Using the Centillion 100 ATMSpeed/155 Switch Modules and Media Dependent Adapters Caution: Centillion 100 modules use electronic components that are sensitive to static electricity. Static discharge from your clothing or other items around you, even at levels that do not create a spark, can cause damage. You should take all possible precautions to prevent static discharge damage when working with printed circuit boards. Keep each board in its protective conductive bag until you are ready to install it.

Installing the ATMSpeed/155 Modules Replacing a Module Note: To minimize configuration conflicts, you should replace a module with another identical module. The configuration of the new module is the same as the previously installed module in that slot. If the module you replace is not identical to the module previously in that slot, the module remains inoperative until you reconfigure it from the SpeedView application.
Chapter 3 Applications and Default Configuration This chapter provides connection instructions for typical ATMSpeed/155 applications. The chapter also describes the factory-set default configuration for the ATMSpeed/155 module. ATMSpeed/155 Port Applications You can connect the ATMSpeed/155 module for optimal LAN performance.
Using the Centillion 100 ATMSpeed/155 Switch Modules and Media Dependent Adapters Connecting Centillion 100 Switches through an Intermediate ATM Switch Two Centillion 100 switches can communicate through an intermediate ATM switch if each switch is connected to a port on the intermediate ATM switch. To connect two Centillion 100 switches through an intermediate ATM switch, follow these steps: 1. Configure the ATMSpeed/155 module ports. To configure ATM ports, refer to Using SpeedView 2.1 for Windows.
Applications and Default Configuration Connecting an ATM LAN Emulation Station to a Centillion 100 Switch To connect an ATM LAN emulation station to a Centillion 100 switch, follow these steps: 1. Configure the ATMSpeed/155 ports. To configure ATM ports, refer to Using SpeedView 2.1 for Windows. 2. Connect one end of the fiber cable to the ATMSpeed/155 module port. The SC connector of the fiber cable is keyed. 3. Connect the other end of the fiber cable to the other ATM switch. 4.
Using the Centillion 100 ATMSpeed/155 Switch Modules and Media Dependent Adapters Parameter Descriptions The physical type, networks timing, physical media type and speed of the ATM ports are not configurable. They are fixed at the factory for each model type. You can use SpeedView to enable or disable the state of an ATM port. The loop timing, networks timing, scrambling, and physical loop parameters are configurable, as described in this section.
