Chapter 1: Introduction
Welcome
24-port 10/100 + 2-Port Gigabit Switch with WebView
Chapter 1: Introduction
Welcome
Thank you for choosing the 24-port 10/100 + 2-Port Gigabit Switch with WebView. This Switch will allow you to
network better than ever.
This new Linksys rackmount switch delivers non-blocking, wire speed switching for your 10, and 100 megabit
network clients, plus multiple options for connecting to your network backbone. Twenty-four 10/100 ports wire
up your workstations, while the two integrated 10/100/1000BaseTX ports connect to other switches and the
backbone at Gigabit speeds. And the mini GBIC port allows future expansion to alternate transmission media like
optical fiber.
It features WebView monitoring and configuration via your web browser, making it easy to manage the 26 VLANs
and up to 7 trunking groups. Or if you prefer, you can use the integrated console port to configure the switch.
The non-blocking, wire-speed switching forwards packets as fast as your network can deliver them.
All ports have automatic MDI/MDI-X crossover detection. 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.
Use the instructions in this User Guide to help you connect the Switch, set it up, and configure it to bridge your
different networks. These instructions should be all you need to get the most out of the 24-port 10/100 + 2-Port
Gigabit Switch with WebView.

The Side Panel
24-port 10/100 + 2-Port Gigabit Switch with WebView
RJ-45 Ports
The Switch is equipped with twenty-four auto-sensing RJ-45 ports. These RJ-45 ports support network speeds of
either 10Mbps or 100Mbps, 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 (10Mbps or 100Mbps), 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)
cable. For more information on twisted-pair cabling, refer to the Twisted-Pair Cabling section.
The Gigabit Expansion Ports
The Switch is equipped with one miniGBIC port and two Gigabit Ethernet ports that provide for the installation of
one expansion module. These ports provide links to high-speed network segments or individual workstations at
speeds of up to 1000Mbps (Gigabit Ethernet).
To establish a Gigabit Ethernet connection, you will need to install an MGBT1, MGBSX2, or MGBLH1 Gigabit
expansion module and use Category 5e cabling or fiber optic cabling. for more information on fiber optic cabling,
refer to the Fiber Optic Cabling section.
The Console Port
The Switch is equipped with a serial port labeled CONSOLE (located on the front of the switch) that allows you to
connect to a computer’s serial port (for configuration purposes) using the provided serial cable. You can use
HyperTerminal to manage the Switch using the console port.
With this and many other Linksys products, your networking options are limitless. Go to the Linksys website at
www.linksys.com for more information about products that work with the Switch.

Chapter 3: Connecting the Switch
Overview
24-port 10/100 + 2-Port Gigabit Switch with WebView
Chapter 3: Connecting the Switch
Overview
This chapter will explain how to connect network devices to the Switch. For an example of a typical network
configuration, see the application diagram shown in Figure 3-1.
When you connect your network devices, make sure you don’t exceed the maximum cabling distances, which are
listed in the following table:
Maximum Cabling Distances.
*A hub refers to any type of 100Mbps hub, including regular hubs and stackable hubs. A 10Mbps hub connected
to another 10Mbps hub can span up to 100 meters (328 feet)
Table 1: Maximum Cabling Distances

Pre-Installation Considerations
24-port 10/100 + 2-Port Gigabit Switch with WebView
Pre-Installation Considerations
Fast Ethernet Considerations
If you will be using the Switch for Fast Ethernet (100Mbps) applications, you must observe the following
guidelines:
Full-Duplex Considerations
As previously mentioned, the Switch provides full-duplex support for its RJ-45 ports. Full-duplex operation allows
data to be sent and received simultaneously, doubling a port’s potential data throughput.
If you will be using the Switch in full-duplex mode, the maximum cable length using Category 5 cable is 328 feet
(100 meters).
Positioning the Switch
Before you choose a location for the Switch, observe the following guidelines:
• Make sure that the switch is accessible and that the cables can be connected easily.
• Keep cabling away from sources of electrical noise, power lines, and fluorescent lighting fixtures.
• Position the Switch away from water and moisture sources.
• To ensure adequate air flow around the Switch, be sure to provide a minimum clearance of two inches (50
mm).
• Do not stack free-standing Switches more than four units high.
• Connect Network Devices
Hardware Installation
To connect network devices to the Switch, follow these instructions:
1. Make sure all the devices you will connect to the Switch are powered off.
2. Connect a Category 5 Ethernet network cable to one of the numbered ports on the Switch.
3. Connect the other end to a PC or other network device.

Placement Options
24-port 10/100 + 2-Port Gigabit Switch with WebView
4. Repeat steps 2 and 3 to connect additional devices.
5. If you are using the Gigabit port, connect a Category 5e Ethernet network cable to the Gigabit port on the
Switch, and connect the other end to a Gigabit server or other network device.
6. If you are using the mini-GBIC port, then connect the mini-GBIC module to the mini-GBIC port. For detailed
instructions, refer to the module’s documentation.
7. Connect the supplied power cord to the Switch’s power port, and plug the other end into an electrical outlet.
8. Power on the devices connected to the Switch. Each active port’s corresponding LED will light up on the
Switch.
Placement Options
There are two ways to physically install the Switch, either set the Switch on its four rubber feet for desktop
placement or mount the Switch in a standard-sized, 19-inch high rack for rack-mount placement.
Desktop Placement
1. Attach the rubber feet to the recessed areas on the bottom of the Switch. See Figure 3-1.
2. Place the Switch on a desktop near an AC power source.
3. Keep enough ventilation space for the Switch and check the environmental restrictions mentioned in
specifications as you are placing the Switch.
4. Connect the Switch to network devices according to the Hardware Installation instructions, above.
Figure 3-3: Attaching the Brackets to the Switch (Front
Panel Forward)
NOTE: If you need to reset the Switch, remove the power cord
from the back of the Switch and then reconnect it.
IMPORTANT: Make sure to use the power cord
that is supplied with the Switch. Use of a different
power cord could damage the Switch.
Figure 3-2: Attaching the Rubber Feet to the Bottom of
the Switch
IMPORTANT: Make sure to use the screws supplied with
the mounting brackets. Using incorrect screws could
damage the Switch and would invalidate your warranty.

24-port 10/100 + 2-Port Gigabit Switch with WebView
Rack-Mount Placement
To rack-mount the Switch in any standard 19-inch rack, follow the instructions described below.
1. Place the Switch on a hard flat surface with the front panel faced towards your front side
2. Attach a rack–mount bracket to one side of the Switch with the supplied screws. Figure 3-2 shows how to
attach brackets to one side of the Switch.
3. Secure the brackets tightly.
4. Follow the same steps to attach the other bracket to the opposite side.
5. After the brackets are attached to the Switch, use suitable screws to securely attach the brackets to any
standard 19-inch rack as shown in Figure 3-3.
6. Connect the Switch to network devices according to the Hardware Installation instructions.
Uplinking the Switch
To uplink the Switch, connect one end of a Cat5 (or better) cable into one of the 24 10/100 ports, and then
connect the other end of the cable into the peripheral device’s uplink port. MDI/MDIX will automaticlaly detect the
speed and cable type.
The hardware installation is complete,. Proceed to Chapter 4: Setting Up the 24-port 10/100 + 2-Port Gigabit
Switch with WebView, for directions on how to set up the Switch.
