Introduction

The 9A426-02 ATM Module is a hardware-based switching module that supports multiple interfaces simultaneously. The module’s interconnecting interfaces include:

Chapter 1

• Up to two front panel ATM interfaces via user-installed ATM Port Interface Modules (APIMs)

• A ﬁxed interface to the SmartSwitch 9000’s Internal Network Bus (INB)

• A user-conﬁgurable interface to the SmartSwitch 9000’s Flexible Network Bus (FNB-1 or FNB-2)

Each data packet, regardless of the interface in which the packet enters the module (ATM, FNB, or INB), is initially converted into a common format known as a canonical frame. Each canonical frame’s header section contains source and destination information. All canonical frames are forwarded to the module’s group of SmartSwitch Application Speciﬁc Integrated Circuits (ASICs) collectively known as the SmartSwitch Core.

The SmartSwitch Core can process data in two modes: as a traditional switch or as a Secure Fast Switch (SFS). When operating as a traditional switch, the Fast Packet Switch makes ﬁltering/forwarding decisions based on Destination Address, with standard IEEE 802.1d learning. When operating in SFS mode, all ﬁltering/forwarding decisions are based on a Destination Address-Source Address pair, and the associated receive/transmit port.

Canonical frames that enter the 9A426-02 Module via the backplane interface (FNB or INB) and are destined for the module’s front panel interface(s), are converted by the module’s ATM Network Interface Block (ANIB) into 53 byte ATM cells. The ANIB uses a separate set of ASICs to perform hardware-based packet to cell conversions. This conversion process is an integral part of the module’s ability to provide high-performance interconnections between legacy LANs and ATM attached networks.

Introduction

Conversely, canonical frames destined for the FNB bus on the SmartSwitch 9000 backplane are converted into FDDI packets via the 9A426-02 Module’s FDDI Network Interface Block (FNIB), and then forwarded onto the FNB.

Canonical frames destined for the INB bus on the SmartSwitch 9000 backplane are converted into ﬁxed length data packets via the 9A426-02 Module’s INB Network Interface Block (INB NIB), and then forwarded onto the INB.

Features

Processor

The 9A426-02 Module is equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions within a scalable RISC-based architecture.

SmartSwitch Core

The 9A426-02 Module incorporates the SmartSwitch Core, a collection of custom Application Speciﬁc Integrated Circuits (ASICs) designed speciﬁcally for high speed switching. The SmartSwitch ASIC bus is 64 bits wide with a bandwidth of 640 Mbps. Since all frame translation, address lookups, and forwarding decisions are performed in hardware, the 9A426-02 Module can obtain a throughput performance of greater than 750K pps.

Management

The 9A426-02 Module has one full implementation of SMT (Version 7.3) and SNMP for local and remote management. Local management is provided thr ough the RS-232 Com ports on the SmartSwitch 9000 Environmental Module using a standard VT-220™ terminal or emulator, or via telnet. Remote management is achieved through Cabletron’s SPECTRUM or any SNMP compliant management tool. Switching statistics of the selected FNB interface include frames ﬁltered, frames forwarded, and all Spanning Tree Protocol parameters.

Connectivity

The 9A426-02 Module has two front panel ATM interfaces. An ATM Port Interface Module (APIM) can be installed in one (or both) interface(s). The 9A426-02 Module also has one interface to the INB-2 backplane, and one user-conﬁgurable interface to the SmartSwitch 9000 FNB backplane (either FNB-1 or FNB-2, or neither).

Management Information Base (MIB) Support

The 9A426-02 Module provides MIB support including:

• IETF A ToM MIB

• IETF FDDI MIB

• IETF Bridge MIB

• A host of Cabletron Enterprise MIBs

Preparing and Installing the 9A426-02 Module

Chapter 2

This chapter describes the physical layout of the 9A426-02 Module and explains how to prepare and install the module in a SmartSwitch 9000 chassis.

Never expose the module’s components to Electr ostatic Dischar ge: Make sure you

WARNING

have attached the module’s disposable grounding strap to your wrist and always place the module on a non-conductive surface.

Unpacking the Module

1. Carefully remove the module from the shipping box. (Save the box and packing materials in the event the module must be reshipped.)

2. Remove the module from the plastic bag. Observe all precautions to prevent damage from Electrostatic Discharge (ESD).

3. Carefully examine the module, checking for damage. If any damage exists, DO NOT install the module. Contact Cabletron Systems Technical Support immediately.

The Module’s Physical Layout

The 9A426-02 Module has two major circuit boards on which components are attached (see Figure 2-1). The module’s base-level circuit board is known as the motherboard. The module’s second-level circuit board is known as the daughterboard. The removable daughterboard attaches to the motherboard’s connectors and standoffs. Both the motherboard and the daughterboard contain components that are accessible to the user.

The User Accessible Components on the motherboard of a 9A426-02 Module are positioned in close proximity to one another. Therefore, to attain easier access for removing a desired component, you may opt to remove an additional component. For example, you may remove an SRAM SIMM to gain better access for removing a Look-Up Engine.
