Chapter 1: Introduction Overview The SMCGS8P-Smart is an intelligent Layer 2 switch with 8 10/100/1000BASE-T ports, one of which is a Gigabit combination port* that is shared with an SFP transceiver slot. The switch’s 8 10/100/1000 Mbps ports support the IEEE 802.3af Power-over-Ethernet (PoE) standard that enables DC power to be supplied to attached devices over the data wire pairs in the connecting Ethernet cable.
1 Introduction Switch Architecture The switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The 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.
1 Description of Hardware Description of Hardware 10/100/1000BASE-T Ports The switch contains 8 RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all ports on the 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. (See “1000BASE-T Pin Assignments” on page B-3.

1 Features and Benefits Features and Benefits Connectivity • 8 10/100/1000 Mbps ports for easy Gigabit Ethernet integration and for protection of your investment in legacy LAN equipment. • All RJ-45 ports support IEEE 802.3af standard Power-over-Ethernet • 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.
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. the switch have, therefore, been recognized as one of the most important building blocks for today’s networking technology.
2 Network Planning Application Examples The 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 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. You can easily connect a PoE device to a switch port and allow power to be supplied over the connecting cable.
2 Application Examples PoE Power 1 2 3 4 5 6 7 8 LINK/ACT 1 2 3 4 5 6 7 Status 8 MiniGBIC ... Power-over-Ethernet Devices 10/100 Mbps Full Duplex Servers 1000 Mbps Full Duplex ... Network Segment 100 Mbps Workstations 100 Mbps Full Duplex Standard LAN PoE Figure 2-2 Collapsed Backbone Meeting Room With 8 1000Mbps parallel bridging ports (i.e., 8 distinct collision domains), this switch can function as an efficient bridged node that is ideal for a meeting room environment.
2 Network Planning Making VLAN Connections The switch supports VLANs that 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 Application Notes 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. For network applications that require routing between dissimilar network types, you can attach the switch directly to a multi-protocol router. 3.

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.
3 Installing the Switch RJ-45 Connector Figure 3-1 RJ-45 Connections Equipment Checklist After unpacking the switch unit, 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.
3 Mounting 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.). • Mechanical Loading: Do not place any equipment on top of a rack-mounted unit. • Circuit Overloading: Be sure that the supply circuit to the rack assembly is not overloaded.
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 Attach the four adhesive feet to the bottom of the first switch. MiniG BIC 5 1 2 3 6 7 1.
3 Installing an Optional SFP Transceiver 2. Set the device on a flat surface near an AC power source, making sure there are 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 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. 100-240V ~50-60Hz 1.5A Figure 3-6 Power Socket 2. Plug the other end of the cable into a grounded, 3-pin, AC power source. 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 socket type in your country. 3.
Chapter 4: Making Network Connections Connecting Network Devices The switch units 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. 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 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 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.
4 Fiber Optic SFP Devices 3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation. Figure 4-3 Making Connections to SFP Transceivers 4. 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.
4 Making Network Connections Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed in the manuals for these products. However, note that because switches break up the path for connected devices into separate collision domains, you should not include the switch or connected cabling in your calculations for cascade length involving other devices.

4 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. To best manage the physical implementations of your network, follow these guidelines: • Clearly label the opposing ends of each cable.
Appendix A: Troubleshooting Diagnosing Switch Indicators Table A-1 Troubleshooting Chart Symptom Action Power LED is Off • Check connections between the switch, the power cord, and the wall outlet. • Contact your dealer for assistance. • Contact our Technical Support. Link LED is Off • Verify that the switch and attached device are powered on. • Be sure the cable is plugged into both the switch and corresponding device.
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 a Web browser, or other network management software tools.
Appendix B: Cables Twisted-Pair Cable and Pin Assignments For 10BASE-T/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. Also, an RJ-45 connector must be attached to both ends of the cable.
