Chapter 1: Introduction Overview The ES4512C, ES4524C and ES4548C Gigabit Ethernet Switches are intelligent switches with 12/24/48 10/100/1000BASE-T ports, four of which are combination ports that are shared with four SFP transceiver slots. 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.
50-60Hz 2A Figure 1-3. ES4548C Front and Rear Panels Switch Architecture The ES4512C/24C/48C Gigabit Ethernet switches employ 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 feature full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.
The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of the RJ-45 ports (ports 9~12 in the ES4512C, ports 21~24 in the ES4524C, and ports 45~48 in the ES4548C). In its default configuration, if an SFP transceiver (purchased separately) is installed in a slot and has a valid link on its port, the associated RJ-45 port is disabled and cannot be used.
The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following table. Port Link and Activity Full Duplex Operation SFP Port Enabled Figure 1-4. ES4512C Port LEDs Port Link and Activity 1000=Green 10/100=Yellow Link Power...

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. These switches have, therefore, been recognized as one of the most important building blocks for today’s networking technology.
Network Planning Application Examples The ES4512C/24C/48C Gigabit Ethernet switches are not only designed to segment your network, but also to provide a wide range of options in setting up network connections and linking VLANs. Some typical applications are described in the following pages.
Network Aggregation Plan With 12, 24 or 48 parallel bridging ports (i.e., 12, 24 or 48 distinct collision domains), the ES4512C/24C/48C can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10/100/1000BASE-T ports on the ES4524C are providing 1000 Mbps connectivity for up to 24 segments 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 a Gigabit Ethernet Switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.
Application Examples Making VLAN Connections These switches support 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 Switches 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. •...
Then, before beginning the installation, be sure you have all other necessary installation equipment. Package Contents • Gigabit Ethernet Switch (12-port ES4512C, 24-port ES4524C or 48-port ES4548C) • Four adhesive foot pads • Bracket Mounting Kit containing two brackets and four screws for attaching the brackets to the switch •...
Mounting Mounting A switch unit 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: •...
Installing the Switch Mount the device in the rack, using four rack-mounting screws (not provided). E S 4 5 2 4 Figure 3-3. Installing the Switch in a Rack If installing a single switch only, turn to “Connecting to a Power Source” at the end of this chapter.
Montage (Rack Mounting Instructions - German) Wenn Sie nur einen Switch installieren, dann springen Sie bitte über zu "Verbinden mit einer Stromquelle" auf Seite 3-7 am Ende dieses Kapitels. Wenn Sie mehrere Switches installieren möchten, dann montieren Sie sie untereinander in einer beliebigen Reihenfolge.

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. 100-240V~,50-60HZ 2A Figure 3-6. Power Socket Plug the other end of the cable into a grounded, 3-pin socket.
Installing the Switch 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 table.
Chapter 4: Making Network Connections Connecting Network Devices The ES4512C/24C/48C 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 transceivers.
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 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.
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.

Troubleshooting Installation Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (such as the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.
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.
