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.

Summary of Hardware Features

Table 1-1 summarizes the hardware features supported by the

Switch.

Table 1-1 Hardware Features

Feature Description

Auto-negotiation Supported on all ports.

Forwarding Modes Store and Forward.

Mac Address Table 8K

Port throughput z2816: 32Gbps

z2824: 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:

z10BASE-T half duplex

z10BASE-T full duplex

z100BASE-TX half duplex

z100BASE-TX full duplex

z1000BASE-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.
