INTRODUCTION

Welcome to the Cabletron Systems

Guide

for the ESX-1320 and ESX-1380 Ethernet Workgroup Switches.

ESX-1320/ESX-1380 Installation

This manual describes the ESX-1320 and ESX-1380 switches and
provides information concerning installation and troubleshooting.

The ESX-1320 and ESX-1380 Ethernet Workgroup Switches, shown in
Figure 1-1, are standalone network switch devices. Except for the
difference in the network media supported (ESX-1320, RJ45 Twisted P air
ports and ESX-1380, Multimode Fiber Optic ST ports), the two ESX
switches are identical in operation.

Introduction

1.1 USING THIS MANUAL

You should have a general w orking kno wledge of Ethernet or IEEE 802.3
type data networks and their physical layer components, prior to installing
the ESX. The following summarizes the organization of this manual.

Chapter 1,

Introduction

, provides instructions for using this manual,
product features, document conventions, related documents, and how to
contact Cabletron Technical Support.

Chapter 2,

Controls and Indicators,

discusses the controls and

indicators for the ESX.
Chapter 3,

Installation,

provides instructions required to unpack the
ESX, perform pre-installation testing, install the ESX, and connect the
ESX to the network.

Chapter 4,

Troubleshooting

, provides detailed troubleshooting

procedures for the ESX.
Appendix A,

Specifications

, contains information on functionality and
operating specifications, connector pinouts, environmental requirements,
and physical properties.

Appendix B,

Ethernet Cabling Requirements

, contains information on

general networking guidelines.

1.2 FEATURES

i960 RISC Processor Controlled

The ESX complies to the PLUS Architecture with Dual Intel i960 RISC
processors and provides advanced management capabilities such as
SNMP, RMON, and DLM. The ESX provides the option of using
Cabletron Systems Distributed LAN Monitor (DLM) software to locally
poll and monitor any SNMP or IP device.

1-2 ESX-1320/ESX-1380 Installation Guide

Features

Connectivity

The ESX-1320 switch connects to the external Ethernet networks or
workstations through the 12 standard RJ45 connectors on its front panel.
The RJ45 connectors (interface ports) support Unshielded Twisted Pair
(UTP) and Shielded Twisted Pair (STP) cabling at lengths up to 100
meters. The ports are IEEE 802.3 10BASE-T compliant.

The ESX-1380 switch connects to the external Ethernet networks or
workstations through the 12 Fiber Optic ST connectors on its front panel.
The ports are Fiber Optic Inter-Repeater Link (FOIRL) compliant.

The ESX provides a port located on the front panel that supports one
Cabletron Systems Bridge/Router Interface Module (BRIM). BRIMs are
an optional feature for the ESX that provide flexible, integrated switching
functions to the workgroup and enterprise network hub. Refer to the

Release Notes

Memory

for a list of BRIMs currently supported by the ESX.

The ESX has 4 Megabytes (MB) of Shared Dynamic Random Access
Memory (SDRAM), 4 MB of Local Dynamic Random Access Memory
(LDRAM), and 2 MB of FLASH Electrically Erasable Programmable
Read Only Memory (FLASH EEPROM). A new firmware image can also
be loaded while the system is operating through a Runtime Download.
This option allows the loading of a new firmware image from a network
interface into FLASH memory while the ESX is operating with the “old”
image. In addition, the ESX motherboard provides the option of
upgrading memory capacity by using Single In-line Memory Modules
(SIMMs). Cabletron Systems currently offers an 8 MB upgrade for
LDRAM and SDRAM (Part Number 8MB-SCM-UGK-60). Note that the
SDRAM is used for packet processing; the LDRAM is used for statistical
information and RMON support.

Full Duplex Switched Ethernet (FDSE)

Each switched Ethernet port supports full wire-speed Ethernet
communications and can be configured to operate in FDSE mode. FDSE
allows each port to provide a dedicated 20 Mbps bandwidth for file server
or high-end workstation connections.

ESX-1320/ESX-1380 Installation Guide 1-3

Chapter 1:

Management

Introduction

The ESX can be managed using Local Management (LM) tools or remote
SNMP management stations. Out-of-band Local Management is provided
through RS232 COM ports on the front panel using a standard VT220 or
VT320 terminal or emulator. In-band remote management is possible
through any SNMP compliant Network Management System (NMS).

Traditional Switching

The ESX provides Traditional Switching or future S

ECUREFAST

Switching Virtual Network Services between all of the front panel
interfaces as well as the high-speed uplink BRIM interface. This allows
for future migration to Virtual Network technologies without requiring the
replacement of existing infrastructure purchases.

IEEE 802.3 Compatibility

The ESX provides IEEE 802.1d Spanning Tree Algorithm (STA) support
to enhance the overall reliability of the network and protect against “loop”
conditions. The ESX supports a wide variety of industry standard MIBs
including RFC 1213 (MIB II), RFC 1757 (RMON), and RFC 1493
(Bridge MIB). A full suite of Cabletron Systems Enterprise MIBs pro vide
a wide array of statistical information to enhance troubleshooting.

LANVIEW Diagnostic LEDs

The LANVIEW diagnostic and status monitoring LEDs serve as an
important troubleshooting aid by providing an easy way to observe the
status of individual ports and overall network operations. Chapter 4
provides details about the ESX LANVIEW LEDs.

LCD Display

The front panel LCD Display provides information on power-up
diagnostics, hardware and firmware revision levels, IP address, serial
number, and alarms. This allows non-technical personnel to provide
network technicians with basic information critical to the troubleshooting
process through simple push-button operation. Chapter 4 provides details
about the LCD Display.

The ESX-1320 and ESX-1380 incorporate the Cabletron Systems
LANVIEW status monitoring and diagnostics system. LANVIEW LEDs
(PWR, CPU, TRANSMIT, and RECEIVE) help diagnose problems, such
as power failures or a cable fault.

2.2 RESET BUTTON

The front panel of the ESX has a RESET button that allows you to
re-initialize the processor. Chapter 4 provides procedures for using the
RESET button.

ESX-1320/ESX-1380 Installation Guide 2-1

Chapter 2: Controls and Indicators

2.3 LCD DISPLAY

The ESX is equipped with an LCD display located on the front panel. The
LCD provides status information about the present as well as past
conditions of the ESX. You can view power up diagnostics, firmware
revisions, MAC addresses, IP addresses, and alarm messages. The LCD
displays the most current event, but can store up to 25 past events in
memory. Chapter 4 provides details about the LCD Display.

2.4 NETWORK MANAGEMENT CAPABILITIES

You can control and manage the ESX using any of the following SNMP
network management systems:

• Cabletron Systems Local Management

• Cabletron Systems SPECTRUM

• Cabletron Systems SPECTRUM Element Manager for Windows

• Cabletron Systems Remote SPECTRUM Portable Management
Applications

• Third Party SNMP compliant Network Management Packages

Network management capabilities provide the necessary management
tools for the ESX to operate at full capacity. Your ability to set up
parameters with network management ensures optimal performance of
the ESX.

Refer to the applicable network management package user’s manual for
more information.

2.5 SIMPLEX OR FULL DUPLEX MODE OPERATION

With FDSE, each switched port can be configured to operate in simplex or
full duplex mode. The default is simplex mode.

In simplex mode, a port can send and receive, but not both
simultaneously. Collision detection is turned on. In the full duplex mode,
the transmit and receive paths operate independently, collision detection
is turned off (eliminating the collision domain), and a separate CRC
generator and receive CRC checker are used on the port transmit and
receive lines for error detection.

2-2 ESX-1320/ESX-1380 Installation Guide

Simplex or Full Duplex Mode Operation

To set a port for full duplex operation using MIB Navigator, proceed as
follows:

1. Access Local Management as described in the ESX-1320/ESX-1380

Local Management Guide.

2. Select MIB Navigator via the Local Management Main Menu screen.

MIBNav -> prompt appears.

The

3. Enter the following commands (shown in bold type) at the

MIBNav -> prompt as shown below:

MIBNav -> ctron
MIBNav -> cd 4/3/3/2/1/1
MIBNav -> set 5[x] y

where x equals the port number (1 through 12)

y can equal either 2 for simplex mode or 3 for

where
full duplex mode. For example:

set 5[3] 3 would set

port 3 for full duplex operation.

For more information concerning MIB Navigator, refer to the

ESX-1320/ESX-1380 Local Management Guide.
