Chapter 1: Introduction Overview The Gigabit Ethernet Switches are intelligent multilayer switches (Layer 2, 3) with 24/48 10/100/1000BASE-T ports, four of which are combination ports* that are shared with four SFP transceiver slots (see Figure 1-1, Ports 21-24/45-48). The rear panel provides two slots for single-port 10 Gigabit Ethernet hot-swappable expansion modules, and two stacking ports. Units can be stacked up to eight high through the built-in stacking ports that provide a 48 Gbps stack backplane.
1 Introduction Power Socket Module Slots Redundant Power Socket Stacking Ports Figure 1-2 Rear Panel Switch Architecture These 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. The switches also feature full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. For communications between different VLANs, these switches use IP routing.
Description of Hardware 1 Description of Hardware 10/100/1000BASE-T Ports The switches contain 24/48 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 these switches 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 1-8 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 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 or IP subnets. Some typical applications are described below. Collapsed Backbone The Gigabit Ethernet Switches are 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 or 48 parallel bridging ports (i.e., 24 or 48 distinct collision domains), a Gigabit switch stack 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 in a stack of 48-port Gigabit Ethernet switches are providing 1000 Mbps connectivity through stackable switches. In addition, the switches are also connecting several servers at 10 Gbps.
2 Network Planning 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 5 km, and a 1000BASE-LH link up to 70 km. This allows a switch stack to serve as a collapsed backbone, providing direct connectivity for a widespread LAN.
Application Examples 2 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. 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 Using Layer 3 Routing 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. These Gigabit Ethernet Switches are routing switches that provide 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 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. For network applications that require routing between dissimilar network types, you can attach these switches directly to a multi-protocol router.

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-2.
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. 5. If also installing an RPS, mount it in the rack below the other devices. Desktop or Shelf Mounting 1.
Installing an Optional Module into the Switch 3 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. 5. If also installing an RPS, place it close to the stack.
3 Installing the Switch Installing an Optional SFP Transceiver Figure 3-6 Inserting an SFP Transceiver into a Slot These switches support 1000BASE-SX and 1000BASE-LX, and 1000BASE-LH 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.
Connecting Switches in a Stack 3 Connecting Switches in a Stack Figure 3-7 shows how the stack cables are connected between switches in a stack. Each stacking connection is a 48 Gbps full-duplex high-speed serial link using proprietary stacking cables. The switch supports a line- and ring-topology stacking configuration, or can be used stand alone. To ensure minimal disruption in case a unit or stacking cable fails, we recommend always use a ring-topology.
3 5. Installing the Switch Select the Master unit in the stack by pressing the Master button in on only one of the switches. Only one switch in the stack can operate as the Master, all other units operate in slave mode. If more than one switch in the stack is selected as Master, or if no switches are selected, the system will select the unit with the lowest MAC address as the Master. Stacking Topologies All units in the stack must be connected via stacking cable.
Connecting to the Console Port 3 3. Check the front-panel LEDs as the device is powered on to be sure the Power LED is on. If not, check that the power cable is correctly plugged in. 4. If you have purchased a Redundant Power Supply, connect it to the switch and to an AC power source now, following the instructions included with the package. Connecting to the Console Port The RJ-45 serial port on the switch’s front panel is used to connect to the switch for out-of-band console configuration.

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 XFP or SFP transceivers. Twisted-Pair Devices Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends.
4 Making Network Connections Connecting to PCs, Servers, Hubs and Switches 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. Figure 4-1 Making Twisted-Pair Connections 2. 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 4 Equipment Rack (side view) Network Switch w it ch 10 /1 0 0 6724L 3 ES4524C Punch-Down Block Patch Panel Wall Figure 4-2 Network Wiring 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.
4 3. Making Network Connections 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.
10 Gbps Fiber Optic Connections 4 cable, the cover should be replaced to protect the optics. 2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port. 3.
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.
Connectivity Rules 4 1000 Mbps Gigabit Ethernet Collision Domain Table 4-4 Maximum 1000BASE-T Gigabit Ethernet Cable Length Cable Type Maximum Cable Length Connector Category 5, 5e, 6 100-ohm UTP or STP 100 m (328 ft) RJ-45 Table 4-5 Maximum 1000BASE-SX Gigabit Ethernet Cable Length Fiber Size Fiber Bandwidth Maximum Cable Length Connector 62.
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. Power LED is Amber • Internal power supply has failed. Contact your local dealer for assistance. Diag LED is Amber • Power cycle the switch to try and clear the condition. • If the condition does not clear, contact your local dealer for assistance.
A Troubleshooting Power and Cooling Problems If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses or surges at the power outlet, and verify that the fans on the unit are unobstructed and running prior to shutdown.
Stack Troubleshooting A Stack Troubleshooting If a stack fails to initialize or function, first check the following items: • • • • Check that all stacking cables are properly connected. Check if any stacking cables appear damaged. Check that only one Stack Master button is pressed in. Check that all switches in the stack are powered on. After checking all items, reboot all the switches in the stack. Switches in the stack may be configured using a ring- or line-topology.
