Chapter 1: Introduction Overview The ES3528M V1 switch is a intelligent switch with 24 10/100BASE-T ports, and four Gigabit combination ports1 that are comprised of a RJ-45 port and an SFP transceiver slot. There is also 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.
1 Introduction Switch Architecture This switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. These switches 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.

Features and Benefits 1 Features and Benefits Connectivity • 24 10/100BASE-T ports plus 4 Gigabit combination ports (RJ-45/SFP). • Auto-negotiation enables each RJ-45 port to automatically select the optimum speed (10 or 100 Mbps), and the communication mode (half or full duplex) if this feature is supported by the attached device; otherwise the port can be configured manually. • Independent RJ-45 10/100BASE-T ports with auto MDI/MDI-X pinout selection.
1 1-6 Introduction
Chapter 2: Network Planning 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.
2 Network Planning Application Examples This switch isnot 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 in the following pages. Collapsed Backbone This switch isan excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future.
Application Examples 2 Network Aggregation Plan With 24 parallel bridging ports (i.e., 24 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 10/100BASE-TX ports on the switch are providing 100 Mbps connectivity through layer 2 switches. In addition, the switch is also connecting several servers at 1000 Mbps. Server Farm 10/100 Mbps Segments ... ... Figure 2-2.
2 Network Planning Remote Connection 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-LH link up to 70 km. This allows the switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.
Application Examples 2 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.
2 Network Planning 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. Otherwise back pressure jamming signals may degrade overall performance for the segment attached to the hub. 3.
Chapter 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.
3 Installing the Switch RJ-45 Connector Figure 3-1. RJ-45 Connections Equipment Checklist After unpacking the 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.
Mounting 3 Mounting The switch units 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. (See page C-2.
3 2. Installing the Switch Mount the device in the rack, using four rack-mounting screws (not provided). Figure 3-3. Installing the Switch in a Rack 3. If installing a single switch only, turn to "Connecting to a Power Source" at the end of this chapter. 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 3-4. Attaching the Adhesive Feet 2.
Installing an Optional SFP Transceiver 3 Installing an Optional SFP Transceiver Figure 3-5. Inserting an SFP Transceiver into a Slot The switch supports 1000BASE-SX and 1000BASE-LX, 1000BASE-LH and other SFP-compatible transceivers. To install an SFP transceiver, do the following: 1. Consider network and cabling requirements to select an appropriate SFP transceiver type. 2. Insert the transceiver with the optical connector facing outward and the slot connector facing down.
3 Installing the Switch Connecting to a Power Source To connect a device to a power source: 1. Insert the power cable plug directly into the socket located at the back of the device. Figure 3-6. Power Sockets 2. Plug the other end of the cable into a grounded, 3-pin socket. 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.
Connecting to the Console Port 3 Connecting to the Console Port The DB-9 serial port on the switch’s front panel is used to connect to the switch for out-of-band console configuration. The on-board configuration program can be accessed from a terminal or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are described in the following figure and table. 1 6 5 9 Figure 3-7. Serial Port (DB-9 DTE) Pin-Out Wiring Map for Serial Cable Table 3-1.

Chapter 4: Making Network Connections Connecting Network Devices These switches are 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 devices using optional SFP tranceivers. Twisted-Pair Devices Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
4 2. Making Network Connections If the device is a PC 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 ’Network Wiring Connections" on page 4-2.) Otherwise, attach the other end to an available port on the switch. Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length. 3.
Fiber Optic SFP Devices 4 Fiber Optic SFP Devices An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX, or 1000BASE-LH) can be used for a backbone connection between switches, or for connecting to a high-speed server. Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends. Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable with an LC connector at both ends.
4 Making Network Connections the port to be sure that the connection is valid. The 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic ports operate at 1 Gbps full duplex, with auto-negotiation of flow control. The maximum length for fiber optic cable operating at Gigabit speed will depend on the fiber type as listed under ’1000 Mbps Gigabit Ethernet Collision Domain" on page 4-5.

Maximum 1000BASE-SX Gigabit Ethernet Cable Length Fiber Size Fiber Bandwidth Maximum Cable Length Connector 62.
4 Making Network Connections 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. To best manage the physical implementations of your network, follow these guidelines: • Clearly label the opposing ends of each cable.
Appendix A: Troubleshooting Diagnosing Switch Indicators Table A-1. Troubleshooting Chart Symptom Action Power LED is Off • Power supply is disconnected. • Check connections between the switch, the power cord, and the wall outlet. • Contact your dealer for assistance. Power LED is Amber • Internal power supply has failed. Contact your local dealer for assistance. Diag LED is Amber • Power cycle the switch to try and clear the condition.
A Troubleshooting In-Band Access You can access the management agent in the switch from anywhere within the attached network using Telnet, a Web browser, or other network management software tools. However, you must first configure the switch with a valid IP address, subnet mask, and default gateway. If you have trouble establishing a link to the management agent, check to see if you have a valid network connection. Then verify that you entered the correct IP address.
Appendix B: Cables Twisted-Pair Cable and Pin Assignments For 10/100BASE-TX connections, a 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.
