Chapter 1: Introduction Overview The MIL-SM24004TG Gigabit Ethernet Switch is an intelligent switch with 24 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.
1 Introduction Switch Architecture The MIL-SM24004TG Gigabit Ethernet 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. The switch uses store-and-forward switching to ensure maximum data integrity.
Description of Hardware 1 Status LEDs The LEDs, which are located on the front panel for easy viewing, are shown below and described in the following table.

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. These switches have, therefore, been recognized as one of the most important building blocks for today’s networking technology.
2 Network Planning Application Examples The MIL-SM24004TG Gigabit 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 in the following pages. Collapsed Backbone The MIL-SM24004TG is an 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 MIL-SM24004TG 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 switch are providing 100 Mbps connectivity for up to 24 segments through layer 2 switches. In addition, the switch is also connecting several servers at 1000 Mbps.
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 a Gigabit Ethernet Switch to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.
2 Application Examples 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 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.
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 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: • 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 Installing the Switch This 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. Note that SFP transceivers are keyed so they can only be installed in one orientation. 3.
Connecting to a Power Source 3 Connecting to a Power Source To connect a device to a power source: 1. Insert the power cable plug directly into the receptacle located at the back of the device. 100-240V~,50-60HZ 2A Figure 3-6 Power Receptacle 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 receptacle type in your country. 3.

Chapter 4: Making Network Connections Connecting Network Devices The MIL-SM24004TG 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. Twisted-Pair Devices This 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 4. 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. 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 4-4.

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 Red • Internal power supply has failed. Contact your local dealer for assistance. Diag LED is Red • Power cycle the switch to try and clear the condition.
A 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. 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.
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.
