Chapter 1: Introduction Overview The ES3528M-SFP is an intelligent switch with 24 100BASE SFP transceiver slots, two Gigabit combination ports that are comprised of a RJ-45 port and an SFP transceiver slot and 2 Gigabit stacking ports. There is also an SNMP-based management agent embedded on the main board.
Introduction Switch Architecture The ES3528M-SFP switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. This switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. his switch uses store-and-forward switching to ensure maximum data integrity.

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.
Network Planning Application Examples The ES3528M-SFP 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 in the following pages. Collapsed Backbone The ES3528M-SFP is an excellent choice for mixed Ethernet, Fast Ethernet, and Gigabit Ethernet installations where significant growth is expected in the near future.
Application Examples 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 SFP ports on the switch are providing 100 Mbps connectivity through layer 2 switches.
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 Making VLAN Connections The ES3528M-SFP 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.
Network Planning Application Notes 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. Avoid using flow control on a port connected to a hub unless it is actually required to solve a problem.
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. •...
Installing the Switch Optional Rack-Mounting Equipment If you plan to rack-mount the switch, be sure to have the following equipment available: • Four mounting screws for each device you plan to install in a rack—these are not included • A screwdriver (Phillips or flathead, depending on the type of screws used) Mounting The switch units can be mounted in a standard 19-inch equipment rack or on a desktop or shelf.
Mounting 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. Figure 3-2. Installing the Switch in a Rack If installing a single switch only, turn to “Connecting to a Power Source”...
Installing the Switch If installing a single switch only, go to “Connecting to a Power Source” at the end of this chapter. If installing multiple switches, attach four adhesive feet to each one. Place each device squarely on top of the one below, in any order. If also installing an RPS, place it close to the stack.
Connecting to a Power Source Connecting to a Power Source To connect a device to a power source: Insert the power cable plug directly into the socket located at the back of the device. B PS 1 0 0 /1 1 5/ 22 0 /2 3 0 V 1 .0 /1 .0 /0 .5 /0 .5 A DC IN 5 0 /6 0 HZ...
Chapter 4: Making Network Connections Connecting Network Devices The ES3528M-SFP is designed to interconnect multiple segments (or collision domains) using optional SFP tranceivers. It can be connected to network cards in PCs and servers, as well as to hubs, switches or routers. Two combination 1000BASE-T/SFP ports provide the uplink connection from the switch to other switches or routers at the central office.
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.
Fiber Optic SFP Devices Fiber Optic SFP Devices An optional SFP transceiver (100BASE-FX, 100BASE-BX, 1000BASE-SX, 1000BASE-LX, or 1000BASE-LH) can be used for a backbone connection between switches, or for connecting to a server or PC. Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at both ends.
Making Network Connections The maximum length for fiber optic cable operating at Fast Ethernet speed will depend on the fiber type as listed under “100 Mbps Fast Ethernet Collision Domain” on page 4-5. 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”...

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.
Appendix A: Troubleshooting Diagnosing Switch Indicators Table A-1. Troubleshooting Chart Symptom Action Pwr LED is Off • Power supply is disconnected. • Check connections between the switch, the power cord, and the wall outlet. • Contact your dealer for assistance. Pwr LED is Amber •...
Troubleshooting 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, and verify that the fans on the unit are unobstructed and running prior to shutdown.
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.
