SR224Gv1.2-UG-60210NC BW Table of Contents Chapter 1: Introduction The 24-Port 10/100 + 2-Port Gigabit Switch + 2 miniGBIC Features 1 1 1 Chapter 1: Introduction r The 24-Port 10/100 + 2-Port Gigabit Switch + 2 miniGBIC 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 integrated 10/100/1000BaseTX port connects to the backbone at Gigabit speeds. And the mini GBIC ports allow future expansion to alternate transmission media like optical fiber. It features non-blocking, wire-speed switching that forwards packets as fast as your network can deliver them. Also included are Address Learning and Aging to prevent data transfer errors and Data Flow Control to help prevent packet collisions. The switch provides broadcast storm suppression, has hardware MAC learning, and supports packet filtering and port security. 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-ofline 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.

Gigabit 2 3 Chapter 3: Connecting the 24Port 10/100 + 2-Port Gigabit Switch + 2 miniGBIC Overview ur Network Layout 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. Connecting Network Devices 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. Figure 3-2 3. Connect the other end to a PC or other network device. 4. Repeat steps 2 and 3 to connect additional devices. 5. If you are using a Gigabit port, connect a Category 5e Ethernet network cable to a Gigabit port on the Switch, and connect the other end to a Gigabit server or other network device. 6. If you are using a mini-GBIC port, then connect a mini-GBIC module to a mini-GBIC port. For detailed instructions, refer to the module's documentation. Note: The mini-GBIC ports are compatible with two types of miniGBIC modules, 850 nm and 1310 nm. 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. 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: From Switch Hub Switch or Hub To Switch or Hub* Hub Computer Maximum Distance 100 meters (328 feet) 1 5 meters (16.4 feet) 1 100 meters (328 feet) 1 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). Proceed to the following section, "Placement Options." 4 5 Placement Options There are two ways to physically install the Switch: · · set the Switch on its four rubber feet mount the Switch in a standard-sized, 1U high rack. Appendix A: Glossary 10BaseT - An Ethernet standard that uses twisted wire pairs. 100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs of Category 5 UTP or STP wire. 1000Base-T - Provides half-duplex and full-duplex 1000Mbps Ethernet service over Category 5 links as defined by ANSI/TIA/EIA-568-A. Topology rules for 1000Base-T are the same as those used for 100BaseT. Category 5 link lengths are limited to 100 meters by the ANSI/TIA/EIA-568-A cabling standard. Auto MDI/MDI-X - On a network hub or switch, an auto MDI/MDI-X port automatically senses if it needs to act as a MDI or MDI-X port. The autoMDI/MDI-X capability eliminates the need for crossover cables. Auto-negotiate - To automatically determine the correct settings. The term is often used with communications and networking. For example, Ethernet 10/100 cards, hubs and switches can determine the highest speed of the node they are connected to and adjust their transmission rate accordingly. CAT 5 - ANSI/EIA (American National Standards Institute/Electronic Industries Association) Standard 568 is one of several standards that specify "categories" (the singular is commonly referred to as "CAT") of twisted pair cabling systems (wires, junctions, and connectors) in terms of the data rates that they can sustain. CAT 5 cable has a maximum throughput of 100 Mbps and is usually utilized for 100BaseTX networks. CAT 5e - The additional cabling performance parameters of return loss and farend crosstalk (FEXT) specified for 1000BASE-T and not specified for 10BASE-T and 100BASE-TX are related to differences in the signaling implementation. 10BASE-T and 100BASE-TX signaling is unidirectional-signals are transmitted in one direction on a single wire pair. In contrast, Gigabit Ethernet is bi-directional-signals are transmitted simultaneously in both directions on the same wire pair; that is, both the transmit and receive pair occupy the same wire pair. Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Has a transfer rate of 10 Mbps. Forms the underlying transport vehicle used by several upper-level protocols, including TCP/IP and XNS. For rack-mounting, the Switch has four mounting holes located on each side. Place the Switch in the rack, and secure it with screws. Congratulations! The installation of the 24-Port 10/100 + 2-Port Gigabit Switch + 2 miniGBIC is complete. 6 7 Fast Ethernet - A 100 Mbps technology based on the 10Base-T Ethernet CSMA/CD network access method. Hub - The device that serves as the central location for attaching wires from workstations. Can be passive, where there is no amplification of the signals; or active, where the hubs are used like repeaters to provide an extension of the cable that connects to a workstation. Mbps (Megabits per second) - One million bits per second; unit of measurement for data transmission. MDI (Medium Dependent Interface) - On a network hub or switch, a MDI port, also known as an uplink port, connects to another hub or switch using a straightthrough cable. To connect a MDI port to a computer, use a crossover cable. MDI-X (Medium Dependent Interface Crossed) - On a network hub or switch, a MDI-X port connects to a computer using a straight-through cable. To connect a MDI-X port to another hub or switch, use a crossover cable. Network - A system that transmits any combination of voice, video and/or data between users. Switch - 1. A data switch connects computing devices to host computers, allowing a large number of devices to share a limited number of ports. 2. A device for making, breaking, or changing the connections in an electrical circuit. Topology - A network's topology is a logical characterization of how the devices on the network are connected and the distances between them. The most common network devices include hubs, switches, routers, and gateways. Most large networks contain several levels of interconnection, the most important of which include edge connections, backbone connections, and wide-area connections. UTP - Unshielded twisted pair is the most common kind of copper telephone wiring. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each signal on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable.
