Chapter 1: Introduction Overview The ES3628EA 24 10/100 Ports + 4G L2/L3/L4 Intelligent Switch has 24 100BASE-TX ports, 2 1000BASE-T ports, and 2 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.
Description of Hardware 100BASE-TX and 1000BASE-T Ports The ES3628EA contains 24 100BASE-TX RJ-45 ports that operate at 10/100 Mbps, half or full duplex, and 2 1000BASE-T RJ-45 ports that operate at 1000 Mbps, full duplex. Because all RJ-45 ports on this switch support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs.
Description of Hardware Status LEDs The ES3628EA 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 table.
Introduction System Indicators Figure 1-3 System LEDs Table 1-2 System Status LEDs Condition Status Power On Green Internal power is operating normally. On Amber Internal Power supply fault.

Features and Benefits Features and Benefits Connectivity • 24 100BASE-TX ports for 10 or 100 Mbps Ethernet connections. 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.
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 ES3628EA 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 in the following pages. Collapsed Backbone The ES3628EA 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 28 parallel bridging ports (i.e., 28 distinct collision domains), the ES3628EA can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 100BASE-TX ports on the switch are providing 100 Mbps full-duplex connections for up to 24 local segments through stackable switches.
1000BASE-LX SFP can be used to connect to other buildings in a campus setting, and a 1000BASE-LH SFP transceiver can be used for a long-haul connection to a remote site. The figure below illustrates an ES3628EA switch connecting multiple segments with fiber cable. ES3628EA...
At Layer 3, VLANs are used to create an IP interface, where one or more ports are assigned to the same IP segment. Traffic is automatically routed between different IP segments on the same switch, without any need to configure routing protocols. R&D ES3628EA VLAN 1 Console Power...
VLANs can significantly enhance network performance and security. However, if you use conventional routers to interconnect VLANs, you can lose most of your performance advantage. The ES3628EA provides wire-speed routing, which allows you to eliminate your conventional IP routers, except for a router to handle non-IP protocols and a gateway router linked to the WAN.
Application Notes 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.

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). 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. If installing multiple switches, mount them in the rack, one below the other, in any order.
Mounting 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. Desktop or Shelf Mounting Attach the four adhesive feet to the bottom of the first switch.
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.

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 receptacle located at the back of the device. Figure 3-6 Power Receptacle 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.
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 ES3628EA 24 10/100 Ports + 4G L2/L3/L4 Intelligent 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 other devices using optional SFP transceivers.

Fiber Optic SFP Devices Fiber Optic SFP Devices An optional SFP transceiver (100BASE-FX, 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 As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid. 100BASE-FX fiber optic ports operate a 100 Mbps full duplex. 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic ports operate at 1 Gbps full duplex. All of these SFP modules also support auto-negotiation of flow control.

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 10BASE-T and 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.
