Introduction

The 24-Port 10/100 + 2-Port Gigabit Switch + 2

MiniGBIC

This new Linksys rack-mount switch delivers non-blocking, wire speed

switching for your 10/100 Mbps network clients, plus multiple options

for connecting to your network backbone. Twenty-four 10/100 ports

wire-up your workstations, while the integrated 10/100/1000 ports or

miniGBIC ports connect to your servers or backbone at Gigabit speeds.

The SR224G incorporates non-blocking, wire-speed architecture that

forwards packets as fast as your network can deliver them. It features

broadcast storm suppression that maximizes the system availability.

Also included are Address Learning and Aging function to prevent data

transfer errors and Data Flow Control to help prevent packet loss.

All ports have automatic MDI/MDI-X crossover detection, so you don’t

have to worry about the cable type. Each port independently and

automatically negotiates for best speed and whether to run in half- or

full-duplex mode. Head-of-line blocking prevention keeps your high-

speed clients from bogging down in lower-speed traffic and fast store-

and-forward switching prevents damaged packets from being passed

on into the network.

No matter how intensive your network demands, the Linksys 24-Port

10/100 + 2-Port Gigabit Switch + 2 MiniGBIC has speed, flexibility, and

reliability that you can count on.

Product Overview

Front Panel

The LEDs and network ports are located on the front panel of the

Switch.

Front Panel

LEDs

System (Green) This LED lights up and remains lit when the Switch is

powered on.

1-24 (Green) Each LED lights up when a connection is made through its

corresponding port. It flashes when the corresponding port is active.

Gigabit/miniGBIC 1-2 (Green) The Gigabit/miniGBIC LED lights up

when a connection is made through the corresponding Gigabit port. It

flashes when the corresponding port is active.

Ports

1-24 These ports connect the Switch to network devices,

such as computers.

Gigabit 1-2 The Gigabit RJ-45 ports support 10/100/1000

Mbps connections and are connection points for network

devices such as Gigabit servers. Each Gigabit RJ-45 port is

paired with a miniGBIC port. If a miniGBIC module is present,

the corresponding 10/100/1000 RJ-45 port will be disabled.

MiniGBIC 1-2 The two miniGBIC (Gigabit interface converter)

ports are connection points for miniGBIC modules, so the

Switch can uplink via fiber to another switch or two. The

miniGBIC ports are compatible with the MGBSX1, MGBLH1,

and MGBT1 only.
