HAPTER TL-SL5428 BOUT THE Overview The TL-SL5428 is a Fast Ethernet switch with 24 10/100BASE-TX ports and four Gigabit combination ports that are comprised of an RJ-45 port and an SFP transceiver slot. The switch also includes an SNMP-based management agent embedded on the main board. This agent supports both in-band and out-of-band access for managing the switch.
This prevents errors from being propagated throughout the network. Network Management Options The TL-SL5428 switch contains a comprehensive array of LEDs for “at-a-glance” monitoring of network and port status. It also includes a management agent that allows you to configure or monitor the switch using its embedded management software, or via SNMP applications.
RJ-45 port or SFP slot, as required. Port and System Status LEDs The TL-SL5428 includes a display panel for key system and port indications that simplify installation and network troubleshooting. The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following tables.

HAPTER ETWORK LANNING Introduction to Switching A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology.
ETWORK LANNING Application Examples The TL-SL5428 switch is not only designed to segment your network, but also to provide a wide range of options in setting up network connections. Some typical applications are described below. Collapsed Backbone The TL-SL5428 switch is an excellent choice for Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future.
Network Aggregation Plan With 28 parallel bridging ports (i.e., 28 distinct collision domains), the TL-SL5428 switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10/100BASE-TX ports are providing 100 Mbps connectivity through layer 2 switches.
ETWORK LANNING Remote Connections with Fiber Cable Fiber optic technology allows for longer cabling than any other media type. A 1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a 1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-ZX link up to 100 km.
PPLICATION XAMPLES Making VLAN Connections This switch supports VLANs which can be used to organize any group of network nodes into separate broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in large networks. This provides a more secure and cleaner network environment.
ETWORK LANNING Application Notes 1. Full-duplex operation only applies to point-to-point access (such as when a switch is attached to a workstation, server or another switch). When the switch is connected to a hub, both devices must operate in half-duplex mode. 2.
HAPTER NSTALLING THE WITCH Selecting a Site Switch units can be mounted in a standard 19-inch equipment rack or on a flat surface. Be sure to follow the guidelines below when choosing a location. • The site should: be at the center of all the devices you want to link and near a power outlet.
NSTALLING THE WITCH Ethernet Cabling To ensure proper operation when installing the switch into a network, make sure that the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T operation. Check the following criteria against the current installation of your network: •...

NSTALLING THE WITCH Connecting to a Power Source To connect a switch to a power source: 1. Insert the power cable plug directly into the power socket located at the back of the switch. Figure 3-6 Power Socket 2. Plug the other end of the cable into a grounded, 3-pin, AC power source.
ONNECTING TO THE ONSOLE Connecting to the Console Port The DB-9 serial port on the switch’s rear panel is used to connect to the switch for out-of-band console configuration. The command-line-driven configuration program can be accessed from a terminal or a PC running a terminal emulation program.
ONNECTIONS Connecting Network Devices The TL-SL5428 switch is designed to interconnect multiple segments (or collision domains). It can be connected to network cards in PCs and servers, as well as to hubs, switches or routers. It may also be connected to remote devices using the optional SFP transceivers.
AKING ETWORK ONNECTIONS Connecting to PCs, Servers, Hubs and Switches 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. Figure 4-1 Making Twisted-Pair Connections 2. If the device is a network card and the switch is in the wiring closet, attach the other end of the cable segment to a modular wall outlet that is connected to the wiring closet.
WISTED EVICES Network Wiring Connections Today, the punch-down block is an integral part of many of the newer equipment racks. It is actually part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follows.
AKING ETWORK ONNECTIONS Fiber Optic SFP Devices An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX, or 1000BASE-ZX) can be used for a backbone connection between switches, or for connecting to a high-speed server. Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends.
ONNECTIVITY ULES Figure 4-3 Making Fiber Port Connections 4. As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid. The 1000BASE-SX, 1000BASE-LX, 1000BASE-ZX fiber optic ports operate at 1 Gbps, full duplex, with auto-negotiation of flow control.
AKING ETWORK ONNECTIONS 1000BASE-T Cable Requirements All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) or Category 6 cable should be used.

AKING ETWORK ONNECTIONS Cable Labeling and Connection Records When planning a network installation, it is essential to label the opposing ends of cables and to record where each cable is connected. Doing so will enable you to easily locate inter-connected devices, isolate faults and change your topology without need for unnecessary time consumption.

ROUBLESHOOTING Power Supply Problems If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet.
PPENDIX ABLES Twisted-Pair Cable and Pin Assignments For 10/100BASE-TX connections, the twisted-pair cable must have two pairs of wires. For 1000BASE-T connections the twisted-pair cable must have four pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes.
ABLES 10BASE-T/100BASE-TX Pin Assignments Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).
WISTED ABLE AND SSIGNMENTS Straight-Through Wiring If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on this switch, you can use either straight-through or crossover cable to connect to any device type.) You must connect all four wire pairs as shown in the following diagram to...

Adjusting Existing Category 5 Cabling to Run 1000BASE-T If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T, there are basically three measures that can be applied to try and correct the problem: 1.
