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.

MiniGBIC (1-2) The Switch is equipped with two miniGBIC
ports. These ports provide links to high-speed network
segments or individual workstations at speeds of up to
1000Mbps (Gigabit Ethernet). These ports are shared. If you
use the MiniGBIC1 port, then you cannot use port 12. If
you use the MiniGBIC2 port, then you cannot use port 24.
