Chapter 1: Introduction Overview The ES3528MF-PoE switch is an intelligent PoE switch with 24 10/100BASE-T ports, two 10/100/1000BASE-T ports, and two 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 Power-over-Ethernet Capability The switch’s 26 10/100 Mbps ports support the IEEE 802.3af Power-over-Ethernet (PoE) standard that enables DC power to be supplied to attached devices using wires in the connecting Ethernet cable. Any 802.3af compliant device attached to a port can directly draw power from the switch over the Ethernet cable without requiring its own separate power source.
Description of Hardware 1 automatically. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually. Each port also supports IEEE 802.3x auto-negotiation of flow control, so the switch can automatically prevent port buffers from becoming saturated. SFP Slots The Small Form Factor Pluggable (SFP) transceiver slots are shared with two RJ-45 ports (Ports 27 and 28).
1 Introduction Port and System Status LEDs This switch includes a display panel for key system and port indications that simplifies installation and network troubleshooting. The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following table. Port Status LEDs Combination Gigabit Port Status LEDs Figure 1-2 Port Status LEDs Table 1-2 Port Status LEDs LED Condition Status On/Blinking Green The port has a valid 10/100 Mbps link.
Description of Hardware 1 System Status LED Figure 1-3 System Status LED Table 1-3 System Status LED LED Condition Status System On Green Internal power is operating normally. On Amber Power on Self Test (POST) is in progress. Blinking Amber Power on Self Test (POST) has failed. Off Power off. Power Supply Sockets There is one standard power socket on the rear panel of the switch for the AC power cord.
1 Introduction Features and Benefits Connectivity • 24 10/100BASE-T ports, 2 1000BASE-T ports, and 2 Gigabit combination ports (RJ-45/SFP). • Auto-negotiation enables each RJ-45 port to automatically select the optimum communication mode (half or full duplex) if this feature is supported by the attached device; otherwise the port can be configured manually. • RJ-45 network ports support auto MDI/MDI-X pinout selection.
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. Switches have, therefore, been recognized as one of the most important building blocks for today’s networking technology.
2 Network Planning Application Examples This Fast Ethernet switch is not only designed to segment your network, but also to provide a wide range of options in setting up network connections and linking VLANs or IP subnets. Some typical applications are described below. Supplying PoE The switch is an excellent choice for supplying power to connected PoE devices such as web cameras, IP telephones or access points.
Application Examples 2 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. In a basic stand-alone configuration, it can provide direct full-duplex connections for workstations or servers.
2 Network Planning Network Aggregation Plan With 28 parallel bridging ports (i.e., 28 distinct collision domains), this switch or a stack of 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 in the stack are providing 100 Mbps connectivity through other layer 2 switches. In addition, the switch is also connecting several servers at 1 Gbps.
2 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.
2 Network Planning 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.
Application Notes 2 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 This unit 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: - restrict access to authorized service personnel in accordance with IEC 60950-1. A restricted access location is one where access is secure and limited to service personnel who have a special key, or other means of security.
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 A switch can be mounted in a standard 19-inch equipment rack, on a wall, 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-1.
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.
Installing an Optional SFP Transceiver 3 2. Set the device on a flat surface near an AC power source, making sure there is 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" at the end of this chapter. 4. If installing multiple switches, attach four adhesive feet to each one. Place each device squarely on top of the one below, in any order.
3 Installing the Switch Connecting to a Power Source First verify that the external AC power supply can provide 100 to 240 VAC, 50-60 Hz, 8 A minimum. 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 receptacle type in your country. 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 Receptacle 2.
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 provided in the following figure and table.

Chapter 4: Making Network Connections Connecting Network Devices This 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 devices using optional SFP transceivers. If 802.3af-compliant PoE devices are connected to the switch’s 10/100 Mbps ports, the switch automatically supplies the required power.
4 Making Network Connections Cabling Guidelines The RJ-45 ports on the switch support automatic MDI/MDI-X pinout configuration, so you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs). See Appendix B for further information on cabling. Caution: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.
Twisted-Pair Devices 4 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.
4 Making Network Connections Fiber Optic SFP Devices An optional SFP transceiver (1000BASE-SX/LX/LH or 1000BASE-T) 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.
Connectivity Rules 4 The 1000BASE-SX/LX/LH fiber optic ports operate at 1 Gbps full duplex, with auto-negotiation of flow control. The maximum length for fiber optic cable depends on the fiber type as listed under “1000 Mbps Gigabit Ethernet Collision Domain” on page 4-5. Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed in the manuals for these products.

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, power cord, and wall outlet. • Contact your dealer for assistance. System LED is Flashing Amber • Power cycle the switch to try and clear the condition • If the condition does not clear, contact your dealer for assistance Link LED is Off • Verify that the switch and attached device are powered on.
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, 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.
