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.

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.

Appendix A: Fast Ethernet and Gigabit Ethernet

About Fast Ethernet
1. As the demand for desktop video, multimedia development, imaging, and other speed-intensive applications continues to rise, the need for high performance, fault tolerant LAN technology will become more critical.
2. Standard Ethernet, which has been the most popular networking technology to date with a maximum data throughput of 10Mbps (Megabits per second), is becoming insufficient to handle the latest video, multimedia, and other speed-intensive client/server LAN applications.
3. Among the solutions to the problem of network speed, Fast Ethernet has emerged as the most viable and economical. Capable of sending and receiving data at 100Mbps, it is more than fast enough to handle even the most demanding video and other real-time applications.
4. Although there are a number of different competing Fast Ethernet implementations, 100BaseTX is by far the most popular. Operating on two pairs of Category 5 unshielded twisted-pair (UTP) cabling, 100BaseTX supports high speed signaling and is relatively inexpensive. Because it uses four wires for data transmission and the same packet format, packet length, error control, and management information as 10BaseT, 100BaseTX can be made to communicate with slower 10BaseT equipment when routed through a switch.
5. This backwards compatibility is one of 100BaseTX's major advantages over other forms of Fast Ethernet; it allows critical, speed-dependent network segments to be upgraded to 100BaseTX speeds as needed without re-wiring, refitting, and retraining an entire site. Networks can now mix both slow and fast network segments for different users or departments. Publishing, R&D, video, multimedia, or accounting departments can enjoy a 100Mbps pace, while other corporate segments can operate at slower and more affordable 10Mbps speeds.
About Gigabit Ethernet
Gigabit Ethernet runs at speeds of 1Gbps (Gigabit per second), ten times faster than 100Mbps Fast Ethernet, but it still integrates seamlessly with 100Mbps Fast Ethernet hardware. Users can connect Gigabit Ethernet hardware with either fiber optic cabling or copper Category 5 cabling, with fiber optics more suited for network backbones. As the new Gigabit standard gradually integrates into existing networks, current computer applications will enjoy faster access time for network data, hardware, and Internet connections.

Appendix B: Cabling

Overview
Twisted Pair Cabling and Fiber Optic Cabling are discussed in this appendix.
Twisted Pair Cabling
There are different grades, or categories, of twisted-pair cabling. Category 5 is the most reliable and is highly recommended. Straight-through cables are used for connecting computers to a hub. Crossover cables are used for connecting a hub to another hub (there is an exception: some hubs have a built-in uplink port that is crossed internally, which allows you to link or connect hubs together with a straight-through cable instead).
You can buy pre-made Category 5 cabling, or cut and crimp your own. Category 5 cables can be purchased or crimped as either straight-through or crossover cables. A Category 5 cable has 8 thin, color-coded wires inside that run from one end of the cable to the other. All 8 wires are used. In a straight-through cable, wires 1, 2, 3, and 6 at one end of the cable are also wires 1, 2, 3, and 6 at the other end. In a crossover cable, the order of the wires change from one end to the other: wire 1 becomes 3, and 2 becomes 6. See the diagrams on the next page for more detailed information on straight-through and crossover cabling.
To determine which wire is wire number 1, hold the cable so that the end of the plastic RJ-45 tip (the part that goes into a wall jack first) is facing away from you. Face the clip down so that the copper side faces up (the springy clip will now be parallel to the floor).When looking down on the copper side, wire 1 will be on the far left.
Crimping your own Network Cables
The processes for straight-through cabling and crossed-over cabling are illustrated below.

Fiber Optic Cabling
Fiber optic cabling is made from flexible, optically efficient strands of glass and coated with a layer of rubber tubing, fiber optics use photons of light instead of electrons to send and receive data. Although fiber is physically capable of carrying terabits of data per second, the signaling hardware currently on the market can handle no more than a few gigabits of data per second.
Fiber cables come with two main connector types. The most commonly used fiber optic cable is multi-mode fiber cable (MMF), with a 62.5 micron fiber optic core. Single-mode fiber cabling is somewhat more efficient than multi-mode but far more expensive, due to its smaller optic core that helps retain the intensity of traveling light signals. A fiber connection always require two fiber cables: one transmits data, and the other receives it.
Each fiber optic cable is tipped with a connector that fits into a fiber port on a network adapter, hub, or switch. In the U. S., most cables use a square SC connector that slides and locks into place when plugged into a port or connected to another cable. In Europe, the round ST connector is more prevalent.
You must use the Linksys MGBT1, MGBSX1, or MGBLH1 miniGBIC modules with the Linksys SRW224. The MGBSX1 and the MGBLH1 require fiber cabling with LC connectors. The MGBT1 requires a Category 5 Ethernet Cable with an RJ-45 connector.
