1-1 Chapter 1 Intr oduction 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.
Introduction 1-2 Features Processor The 9H423-28 module is equipped with an advanced Intel i960 micropr ocessor . This micropr ocessor provides a platform for all management functions, such as Spanning T ree, RMON, and MIB support, within a scalable RISC-Based architectur e.
1-3 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.
Introduction 1-4 Arbitration for the backplane is accomplished in the INB T ime Division Multiplexing (ITDM) logic. The arbitration is a three-level scheme that ensur es that no one can get the backplane for more than one time slice at a time. The ITDM RAM contains 256 4-bit locations.

2-3 Installing the 9H423-28 Module Figure 2-2. User Accessible Components Setting the Module DIP Switch The DIP switch on the 9H423-289 module (Figur e 2-2 ), is an eight-switch DIP located near the right and center of the module. Each switch is set according to the functions described in T able 2-1.
Installing the 9H423-28 Module 2-4 See the Cautions at the end of this table. T able 2-1. Function of DIP Switch Switch Function Description 8 Clear Password -1 This module stores user enter ed passwords in NVRAM (Nonvolatile random access memory). T o clear these passwords, toggle this switch and then reset the module’s pr ocessor .
2-5 Installing the 9H423-28 Module Installing the Module in the Smar tSwitch 9000 Chassis T o install the 9H423-28 module in the SmartSwitch 9000 chassis, follow the steps below: 1. Remove the blank panel covering the slot in which the module will be mounted.
Installing the 9H423-28 Module 2-6 W arning: Ensure that the cir cuit card is between the car d guides. Lock down the top and bottom plastic tabs at the same time, applying even pr essur e.
2-7 Installing the 9H423-28 Module The Reset Switch The Reset switch is located on the front panel, under the top plastic tab as shown in Figure 2-4. It serves three functions: r esetting the i960 processor , shutting down the module, or restarting the module.

3-1 Chapter 3 Operation The 9H423-28 module is a twenty-nine port device. T wo front panel RJ21 connectors support twenty-four 10BASE-T ports, along with two RJ45 connectors, ST fiber connectors and a slot for an FEPIM that support four 100BASE-T ports.
Operation 3-2 Figure 3-1. P acket Flow f or the 9H423-28 ENIB/FENIB The Ethernet Network Interface Block (ENIB) and Fast Ethernet (FENIB) convert Ethernet data packets received thr ough front panel ports into a common canonical format that allows the SmartSwitch ASIC Engine to determine the proper destination port.
3-3 Operation Smar tSwitch ASIC The SmartSwitch ASIC is a har dwar e-based switch design that is the key building block of the SmartSwitch 9000 hub. The SmartSwitch ASIC makes all filtering/ forwarding decisions in custom har dware as opposed to softwar e, as in traditional bridges.
Operation 3-4 Figure 3-2. VLAN-based Network VLAN Domains VLAN domains consist of groups of inter connected VLAN switches separated by routing devices. Figur e 3-3 shows such an arrangement. Each group of switches constitutes a VLAN domain. Figure 3-3.
3-5 Operation Fully-Meshed VLAN Domains The switches shown in figure 3-3 above ar e said to be fully meshed. The term “fully meshed” is often used when describing the connections between switches in a domain. Fully meshed implies that there ar e links between all switches to every other switch.
Operation 3-6 i960 Core The i960 core pr ovides the SNMP pr otocol stacks to support industry-standar d MIBs. Additionally , Cabletron enterprise extension MIBs ar e supported for each media type.
3-7 Operation SMB-10 Bus The SMB-10 is a 10Mbs management bus located within the SmartSwitch 9000. This bus is used for inter-chassis communication of modules as well as serving as an side-band management channel into the SmartSwitch 9000.
Operation 3-8 Arbitration for the backplane is accomplished in the INB T ime Division Multiplexing (ITDM) logic. The arbitration is a three-level scheme that ensur es that no one can get the backplane for more than one time slice at a time. The ITDM RAM contains 256 4-bit locations.
3-9 Operation Monar ch/Sla ve Smar tSwitch 9000 Modules All modules in an SmartSwitch 9000 chassis that transfer packets across the INB backplane have identical INB interfaces. However , one of them has to be selected to perform the backplane arbitration.
