1 INTRODUCTION OVERVIEW The ECS3510-26T is a Fast Ethernet Layer 2 switch with 24 10/100BASE-TX ports, and two Small Form Factor Pluggable (SFP) transceiver slots that operate in combination with 1000BASE-T ports 25~26 (see "Front and Rear Panels" on page 23). This switch provides a broad range of powerful features for Layer 2 switching, delivering reliability and consistent performance for your network traffic.
CHAPTER 1 | Introduction Overview SWITCH ARCHITECTURE The switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. This switch uses store-and-forward switching to ensure maximum data integrity.
CHAPTER 1 | Introduction Description of Hardware DESCRIPTION OF HARDWARE 10/100BASE-T PORTS The switch contains 24 RJ-45 ports that operate at 10 Mbps, or 100 Mbps, half or full duplex. Because these ports support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.

2 NETWORK PLANNING INTRODUCTION TO SWITCHING A network switch allows simultaneous transmission of multiple packets via noncrossbar 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.
CHAPTER 2 | Network Planning Application Examples APPLICATION EXAMPLES This 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 This switch is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future.
CHAPTER 2 | Network Planning Application Examples NETWORK AGGREGATION PLAN With 26 parallel bridging ports (i.e., 26 distinct collision domains), these switches 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 on the switch are providing 100 Mbps connectivity for up to 24 segments, while the 1000BASE-T ports are providing connectivity for two Gigabit segments.
CHAPTER 2 | Network Planning Application Examples REMOTE CONNECTIONS WITH FIBER 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, a 1000BASE-LH link up to 80 km, and a 100BASE-FX (SMF) link up to 20 km. This allows the switches to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.
CHAPTER 2 | Network Planning Application Examples 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. VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs.
CHAPTER 2 | Network Planning Application Notes 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. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem.
3 INSTALLING THE SWITCH 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.
CHAPTER 3 | Installing the Switch Ethernet Cabling 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.
CHAPTER 3 | Installing the Switch Equipment Checklist EQUIPMENT CHECKLIST After unpacking this switch, check the contents to be sure you have received all the components. Then, before beginning the installation, be sure you have all other necessary installation equipment.
CHAPTER 3 | Installing the Switch Mounting MOUNTING The switch can be mounted in a standard 19-inch equipment rack, on a desktop or shelf, or on a wall. Mounting instructions for each type of site follow. RACK MOUNTING Before rack mounting the switch, pay particular attention to the following factors: ◆ Temperature: Since the temperature within a rack assembly may be higher than the ambient room temperature, check that the rack-environment temperature is within the specified operating temperature range.
CHAPTER 3 | Installing the Switch Mounting To rack-mount devices: 1. Attach the brackets to the device using the screws provided in the Bracket Mounting Kit. Figure 12: Attaching the Brackets 27 28 2. Mount the device in the rack, using four rack-mounting screws (not provided). Be sure to secure the lower rack-mounting screws first to prevent the brackets being bent by the weight of the switch.
CHAPTER 3 | Installing the Switch Mounting Figure 13: Installing the Switch in a Rack 3. If installing a single switch only, turn to "Connecting to a Power Source" on page 45 at the end of this chapter. 4. If installing multiple switches, mount them in the rack, one below the other.
CHAPTER 3 | Installing the Switch Mounting DESKTOP OR SHELF MOUNTING To attach the switch to a vertical surface: 1. Attach the four adhesive feet to the bottom of the first switch. Figure 14: Attaching the Adhesive Feet ECS35 10-26T 2. Set the device on a flat surface near an AC power source, making sure there are at least two inches of space on all sides for proper air flow. 3. If installing a single switch only, go to "Connecting to a Power Source" on page 45, at the end of this chapter. 4.
CHAPTER 3 | Installing the Switch Installing an Optional SFP Transceiver INSTALLING AN OPTIONAL SFP TRANSCEIVER Figure 15: Inserting an SFP Transceiver into a Slot The SFP slots support the following optional SFP transceivers: ◆ 1000BASE-SX ◆ 1000BASE-LX ◆ 1000BASE-LH ◆ 100BASE- FX To install an SFP transceiver, do the following: 1. Consider network and cabling requirements to select an appropriate SFP transceiver type. 2.
CHAPTER 3 | Installing the Switch Connecting to a Power Source NOTE: SFP transceivers are hot-swappable. The switch does not need to be powered off before installing or removing a transceiver. However, always first disconnect the network cable before removing a transceiver. NOTE: SFP transceivers are not provided in the switch package. CONNECTING TO A POWER SOURCE To connect a switch to a power source: 1. Insert the power cable plug directly into the AC inlet located at the back of the switch.
CHAPTER 3 | Installing the Switch Connecting to the Console Port CONNECTING TO THE CONSOLE PORT This port is used to connect a console device to the access point through a serial cable. The console device can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal. A crossover RJ-45 to DB-9 cable is supplied with the unit for connecting to the console port, as illustrated below. The PIN assignments used to connect to the serial port are described below.

4 MAKING NETWORK CONNECTIONS CONNECTING NETWORK DEVICES This switch is designed to be connected to 10, 100, or 1000 Mbps network cards in PCs and servers, as well as to other switches and hubs. It may also be connected to remote devices using optional 1000BASE-SX, 1000BASE-LX, 1000BASE-LH, or 100BASE-FX SFP transceivers. TWISTED-PAIR DEVICES Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
CHAPTER 4 | Making Network Connections Twisted-Pair Devices CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES 1. Connect one end of a twisted-pair cable segment to the device’s RJ-45 connector. Figure 18: 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. (See the section "Network Wiring Connections" on page 51.
CHAPTER 4 | Making Network Connections Twisted-Pair Devices NETWORK WIRING CONNECTIONS Today, the punch-down block is an integral part of many of the newer equipment racks. Actually it is a part of the patch panel. Instructions for making connections in the wiring closet with this type of equipment follows. 1. Attach one end of a patch cable to an available port on the switch, and the other end to the patch panel. 2.
CHAPTER 4 | Making Network Connections Fiber Optic SFP Devices FIBER OPTIC SFP DEVICES An optional Gigabit SFP (1000BASE-SX, 1000BASE-LX, 1000BASE-LH, or 100BASE-FX) transceiver 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. Each multimode fiber optic port requires 50/ 125 or 62.
CHAPTER 4 | Making Network Connections Fiber Optic SFP Devices Figure 20: 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-LH fiber optic ports operate at 1 Gbps, full duplex, with auto-negotiation of flow control.
CHAPTER 4 | Making Network Connections Connectivity Rules CONNECTIVITY RULES When adding hubs (repeaters) to your network, please follow the connectivity rules listed in the manuals for these products. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.
CHAPTER 4 | Making Network Connections Connectivity Rules Table 7: Maximum 1000BASE-LX Gigabit Ethernet Cable Length Fiber Size Fiber Bandwidth Maximum Cable Length Connector 9/125 micron singlemode fiber N/A 2 m - 5 km (7 ft - 3.
CHAPTER 4 | Making Network Connections Cable Labeling and Connection Records 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.
A TROUBLESHOOTING DIAGNOSING SWITCH INDICATORS Table 12: Troubleshooting Chart Symptom Action Power LED is Off ◆ Check connections between the switch, the power cord and the wall outlet. ◆ Contact your dealer for assistance. Diag LED is Flashing Amber ◆ ◆ Power cycle the switch to try and clear the condition. Link LED is Off ◆ ◆ Verify that the switch and attached device are powered on. ◆ If the switch is installed in a rack, check the connections to the punch-down block and patch panel.
APPENDIX A | Troubleshooting Power and Cooling Problems POWER AND COOLING 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. If you still cannot isolate the problem, the internal power supply may be defective.
B CABLES AND PINOUTS 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. Also, an RJ-45 connector must be attached to both ends of the cable.
APPENDIX B | Cables and Pinouts Twisted-Pair Cable and Pin Assignments 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).
