Notice Safety Information CLASS 1 LASER TRANSCEIVERS Laser Radiation and Connectors When the connector is in place, all laser radiation remains within the fiber. The maximum -6 amount of radiant power exiting the fiber (under normal conditions) is -12.6 dBm or 55 x 10 watts. Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum radiance from the optical port (under worst case -2 3 2 conditions) is 0.8 W cm o

Chapter 1 Introduction The 9H423-28 (Figure 1-1) is a switching module with twenty-four 10 Mbps Ethernet ports and four 100 Mbs Fast Ethernet ports. The module is configured with two RJ21 connectors, two RJ45 connectors, two ST fiber connectors and a slot for an FEPIM. The two RJ21 connectors provide twenty-four 10 Mbps Ethernet ports. The RJ45 connectors, ST connectors and FEPIM (the module supports either the FE-100TX or the FE-100FX) provide the four 100 Mbps Ethernet ports. The t

Introduction Features Processor The 9H423-28 module is equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions, such as Spanning Tree, RMON, and MIB support, within a scalable RISC-Based architecture. Fast Packet Switching The 9H423-28 module incorporates a hardware-based switch design referred to as the SmartSwitch ASIC, a collection of custom ASICs designed specifically for high-speed switching. Because all fr

Introduction negotiate duplex, both the 9H423-28 and the attached device must be configured for auto-negotiation. If only the 9H423-28 is configured for auto-negotiation, the module will set the connection to half duplex at either the 10 Mbps or 100 Mbps rate. This technology is similar to how modems negotiate transmission speed, finding the highest transmission rate possible. Similarly, auto-negotiation determines the highest common speed between two devices and communicates at that

Introduction Arbitration for the backplane is accomplished in the INB Time Division Multiplexing (ITDM) logic. The arbitration is a three-level scheme that ensures that no one can get the backplane for more than one time slice at a time. The ITDM RAM contains 256 4-bit locations. This RAM is used to hold slot numbers of modules participating in INB backplane arbitration. The arbitration engine accesses this RAM once every time slice to get a slot number. That slot number will be grante
