1 Product Overview

Introduction

The 3Com Baseline Switch 2824 and the 3Com Baseline Switch 2816

are versatile, easy-to-use, unmanaged gigabit switches. It is ideal for

users who want the high-speed performance of 10/100/1000 switching

but do not need sophisticated management functions. The Switch is

shipped ready for use, and operational straight out of the box. No

configuration is necessary. Your 3Com Baseline Switch incorporates

the latest in Green technology to yield more than 20% power savings

over the previous generation technology.

Auto-negotiation Supported on all ports.

Forwarding Modes

Store and Forward.

Mac Address Table 8K

Port throughput

z 2816: 32Gbps

z 2824: 48Gbps

Auto MDI/MDIX Supported on all ports.

Traffic Prioritization

The Switch offers priority queuing, which

means all packets that are received are

examined to see if they have been priority

encoded. When a packet is received, the

Switch will read the priority level and

determine the appropriate queue to

forward the packet based on the priority

level. High priority data is forwarded

through the Switch without being delayed

by lower priority data.

This feature can be useful, for example,

during excessive loads when one type of

traffic may require priority over another.

The Switch is configured to comply with

802.1 p, VLAN tagged frames.

Notes:

The traffic prioritization feature supported

by the Switch is compatible with the

relevant sections of the IEEE 802.1 D

standard (incorporating IEEE 802.1 p).

Feature Description

Ethernet Ports

The Switch has 24/16 10/100/1000 Mbps

auto-negotiating ports. Each port

automatically negotiates with the attached

device to determine the correct speed and

duplex mode of operation. Once

negotiated, the port will operate in one of

the following modes:

z 10BASE-T half duplex

z 10BASE-T full duplex

z 100BASE-TX half duplex

z 100BASE-TX full duplex

z 1000BASE-T full duplex

WARNING:

RJ-45 ports. These are shielded RJ-45

data sockets. They cannot be used as

standard traditional telephone sockets, or

to connect the unit to a traditional PBX or

public telephone network. Only connect

RJ-45 data connectors, network telephony

systems, or network telephones to these

sockets. Either shielded or unshielded

data cables with shielded or unshielded

jacks can be connected to these data

sockets.

Mounting 19-inch rack or standalone mounting.

Fanless design

Silent operation whether used in a rack or

desktop situation.

Green Technology

When no connection exists or a short

network cable is used, power consumption

can be reduced automatically to save

energy.

Network Design

The Switch provides high performance switched connections to 10

Mbps, 100 Mbps, and 1000 Mbps hubs, switches, servers and

workstations that need a dedicated switched link.

The following figure illustrates one possible configuration. Each port

has a shielded RJ-45 connector on the front panel. Each port is

capable of operating at 10 Mbps, 100 Mbps or 1000 Mbps. Each port

can automatically determine the speed and the duplex mode of the

connected equipment and provides a suitable switched connection. At

10 Mbps and at 100 Mbps, the ports can operate in half or full duplex

mode. At 1000 Mbps, the ports operate in full duplex mode only.

2 Installing the Switch

WARNING: Safety Information. Before you install or remove

any components from the Switch or carry out any maintenance

procedures, you must read the safety information in Appendix A:

Safety Information in this guide.

AVERTISSEMENT: Consignes de sécurité. Avant d'installer

ou d'enlever tout composant de Switch ou d'entamer une procédure

de maintenance, lisez les informations relatives à la sécurité qui se

trouvent dansl'Appendice A de ce guide.

VORSICHT: Sicherheitsinformationen. Bevor Sie

Komponenten aus dem Switch entfernen oder den Switch hinzufügen

oder Instandhaltungsarbeiten verrichten, lesen Sie die

Sicherheitsanweisungen, die in Anhang A in diesem Handbuch

aufgeführt sind.

ADVERTENCIA: Información de seguridad. Antes de

instalar o extraer cualquier componente del Switch o de realizar

tareas de mantenimiento, debe leer la información de seguridad

facilitada en el Apéndice A de estaguía del usuario.

AVVERTENZA: Informazioni di sicurezza. Prima di installare

o rimuovere qualsiasi componente dal Switch o di eseguire qualsiasi

procedura di manutenzione, leggere le informazioni di sicurezza

riportate nell'Appendice A della presente guida per l'utente.

10

OSTRZEŻENIE: Informacje o zabezpieczeniach. Przed

instalacją lub usunięciem jakichkolwiek elementów z product lub

przeprowadzeniem prac konserwacyjnych należy zapoznać się z

informacjami o bezpieczeństwie zawartymi w Załączniku A

niniejszego podręcznika.

ADVERTÊNCIA: Informações de segurança Antes de

instalar ou remover quaisquer componentes do Switch ou de

executar quaisquer procedimentos de manutenção, leia as

informações de segurança no Appendix A: Safety Information deste

guia.

Package Contents

The switch packaging contains the following for all units:

z One product sealed in a plastic bag

z One power cord for use with the Switch

z One User Guide

z One Installation Guide(LAT-Spanish and Portuguese only)

z One warranty card

z One Rack Mounting Kit

z Four self-adhesive rubber pads

Positioning the Switch

The switch is suited for use in an internal wiring closet, a network

room, or telecommunications room, where it can be mounted in a

standard 19-inch equipment rack, or free-standing.

11

Ensure that the ventilation holes are not obstructed.

When deciding where to position the switch, ensure that:

z Cabling is located away from:

Sources of electrical noise such as radios, transmitters and

broadband amplifiers.

Power lines and fluorescent lighting fixtures.

z The switch is accessible and cables can be connected easily.

z Water or moisture cannot enter the case of the switch.

z Air flow is not restricted around the switch or through the vents in

the side of the switch. 3Com recommends that you provide a

minimum of 25 mm (1 in.) clearance.

z The temperature around the switch does not exceed 40 °C (104

°F).

If the switch is installed in a 19-inch rack or closed assembly its local

air temperature may be greater than room ambient temperature.

z The air is as free from dust as possible.

z The switch is situated away from sources of conductive

(electrical) dust, for example laser printers.

z The unit is installed in a clean, air conditioned environment.

12

z The AC supply used by the switch is separate from that used by

units that generate high levels of AC noise, for example air

conditioning units.

z No more than four switch units are placed on top of one another,

if the units are free-standing.

Rack Mounting

The Switch is 1U high and fits in most standard 19-inch racks.

z Disconnect all cables from the switch before continuing. Remove

all self adhesive pads from the underside of the switch if they

have been fitted.

z If you use a shelf or support ensure that it will not obstruct the air

flow through the side panels of the switch.

To rack-mount the switch:

1) Place the switch the right way up on a hard flat surface, with the

front facing towards you.

2) Locate a securing bracket over the mounting holes on one side of

the front of the switch, as shown in

Figure 2-1.

3) Insert the two screws and tighten with a suitable screwdriver.

13

Figure 2-1 Fitting a front bracket for rack-mounting

You must use the screws supplied with the securing brackets.

Damage caused to the unit by using incorrect screws invalidates your

warranty.

4) Repeat steps 2 and 3 for the other side of the switch.

5) Insert the switch into the 19-inch rack and secure with suitable

screws. Ensure that ventilation holes are not obstructed.

6) Reconnect network cables.

Powering On

The following steps describe how to get the switch powered-on and

ready for operation.

1) Check the network connections and cables.

2) Connect the power supply cable to the appropriate power socket

located on the rear panel of the unit.
