Introduction

The 10/100/1000 Gigabit Switch

The 24-Port 10/100/1000 Gigabit Switch provides non-blocking,

wirespeed switching for your 10, 100, and 1000 megabit network

clients. Drop this Switch in place of your current workgroup hub or

switch, and you can upgrade your high-requirement workstations to full

Gigabit speeds as necessary, while continuing to service other clients at

their current speeds. Or build your network from the ground up, with

appropriate link speeds for each user’s requirements.

Either way, it’s perfect for graphics, multimedia, and other applications

that have to move large files across the network quickly. And with the

24-Port 10/100/1000 Gigabit Switch, when you need to expand your

network even further, its two MiniGBIC ports let you add fiber-optic

capability easily and cost effectively.

With the 24-Port 10/100/1000 Gigabit Switch, you can connect your

existing 10/100 Ethernet network to a Gigabit server backbone without

any additional equipment. 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 speed and duplex mode.

Address learning and aging is supported, as well as 802.3x flow control

with head-of-line blocking prevention to keep your high-speed clients

from bogging down in lower-speed traffic. Fast store-and-forward

switching prevents damaged packets from being passed on into the

network. World famous Linksys reliability and the limited lifetime

warranty give you peace of mind and the rackmount form factor

integrates smoothly into your network infrastructure. Let the Linksys 24-

Port 10/100/1000 Gigabit Switch kick your network into high gear.

System (Green) The System LED will light up when the

Switch is powered on.

Link/Act (Green) Each LED will light up when there is a

connection made through its corresponding port. It will flash

when there is activity on its corresponding port.

Gigabit (Amber) Each LED will light up when there is a Gigabit

connection made through its corresponding port. It will flash

when there is activity on its corresponding port.

Ports

1-24 The Switch is equipped with 24 auto-sensing RJ-45

ports. These RJ-45 ports support network speeds of either

10Mbps, 100Mbps, or 1000Mbps and can operate in half

and full-duplex modes. Auto-sensing technology enables

each port to automatically detect the speed of the device

connected to it and adjust its speed and duplex accordingly.

To connect a device to a port, you will need to use a network

cable. You will need to use Category 5 (or better) cables.
