1 INTRODUCTION OVERVIEW The ECS4310-18T is a Gigabit Smart Switch with 16 1000BASE-T ports, and two 1000BASE-T ports Small Form Factor Pluggable (SFP) transceiver slots. The switch also includes an SNMP-based management agent, which provides both in-band and out-of-band access for managing the switch. The ECS4310-18T provides a broad range of powerful features for Layer 2 switching, delivering reliability and consistent performance for your network traffic.
CHAPTER 1 | Introduction Description of Hardware 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 SFP TRANSCEIVER SLOTS The following table shows a list of transceiver types that have been tested with the switch. For an updated list of vendors supplying these transceivers, contact your local dealer. For information on the recommended standards for fiber optic cabling, see “1000 Mbps Gigabit Ethernet Collision Domain” on page 50.
CHAPTER 1 | Introduction Description of Hardware PORT AND SYSTEM STATUS LEDS The switch 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.
CHAPTER 1 | Introduction Description of Hardware Table 3: SFP Port Status LEDs (17~18) LED Condition Status SFP On Green An SFP transceiver is installed in the slot. Off There is no SFP transceiver installed in the slot. On/Flashing Green Port has established a valid 1000 Mbps network connection. Flashing indicates activity. On/Flashing Amber Port has established a valid 10/100 Mbps network connection. Flashing indicates activity. Off There is no valid link on the port.
CHAPTER 1 | Introduction Description of Hardware POWER SUPPLY SOCKET There is one power socket on the rear panel of the switch. The standard power socket is for the AC power cord.
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 The 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 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 18 parallel bridging ports (i.e., 18 distinct collision domains), the switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 1000BASE-T ports on the switch are providing 1000 Mbps connectivity for up to 16 segments.
CHAPTER 2 | Network Planning Application Examples 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 10 km, and a 1000BASE-LH link up to 80 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN. The figure below illustrates the switch connecting multiple segments with fiber cable.
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. ■ be able to maintain its temperature within 0 to 50 °C (32 to 122 °F) and its humidity within 10% to 90%, non-condensing. ■ provide adequate space (approximately two inches) on all sides for proper air flow.
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 This switch can be mounted in a standard 19-inch equipment rack or on a desktop or shelf. 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 Figure 10: Attaching the Brackets 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 3. If installing a single switch only, turn to “Connecting to a Power Source” on page 44. 4. If installing multiple switches, mount them in the rack, one below the other, in any order. DESKTOP OR SHELF MOUNTING 1. Attach the four adhesive feet to the bottom of the first switch. Figure 12: Attaching the Adhesive Feet 2.
CHAPTER 3 | Installing the Switch Installing an Optional SFP Transceiver INSTALLING AN OPTIONAL SFP TRANSCEIVER Figure 13: Inserting an SFP Transceiver into a Slot The SFP slots support the following optional SFP transceivers: ◆ 1000BASE-SX ◆ 1000BASE-LX ◆ 1000BASE-LH 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 CONNECTING TO A POWER SOURCE To connect a switch to a power source: 1. Insert the power cable plug directly into the AC socket located at the back of the switch. Figure 14: Power Socket 2. Plug the other end of the cable into a grounded, 3-pin, AC power source. NOTE: For International use, you may need to change the AC line cord. You must use a line cord set that has been approved for the socket type in your country. 3.
4 MAKING NETWORK CONNECTIONS CONNECTING NETWORK DEVICES The 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, or 1000BASE-LH 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. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. Figure 15: 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. Otherwise, attach the other end to an available port on the switch.
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. It is actually 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 transceiver (1000BASE-SX, 1000BASE-LX or 1000BASELH) 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 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends.
CHAPTER 4 | Making Network Connections Fiber Optic SFP Devices Figure 17: 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 - 10 km (7 ft - 6.2 miles) LC Table 8: Maximum 1000BASE-LH Gigabit Ethernet Cable Length Fiber Size Fiber Bandwidth Maximum Cable Length Connector 9/125 micron singlemode fiber N/A 2 m - 80 km (7 ft - 49.
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 11: 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. ◆ ◆ Power cycle the switch to try and clear the condition. ◆ ◆ 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 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. CAUTION: DO NOT plug a phone jack connector into any RJ-45 port.
APPENDIX B | Cables 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).

APPENDIX B | Cables Twisted-Pair Cable and Pin Assignments 1000BASE-T PIN ASSIGNMENTS All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive.
APPENDIX B | Cables Fiber Standards 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. Replace any Category 5 patch cables with high-performance Category 5e or Category 6 cables. 2. Reduce the number of connectors used in the link. 3. Reconnect some of the connectors in the link.
