2 NETWORK PLANNING INTRODUCTION TO SWITCHING A network switch allows simultaneous transmission of multiple packets via noncrossbar 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.
CHAPTER 2 | Network Planning Application Examples 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.
CHAPTER 2 | Network Planning Application Examples 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.
CHAPTER 2 | Network Planning Application Examples 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.
CHAPTER 2 | Network Planning 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. VLANs can be based on untagged port groups, or traffic can be explicitly tagged to identify the VLAN group to which it belongs.
CHAPTER 2 | Network Planning Application Examples 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.
CHAPTER 2 | Network Planning 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 these switches directly to a multi-protocol router.

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.
CHAPTER 3 | Installing the Switch Ethernet Cabling ETHERNET CABLING To ensure proper operation when installing the switches into a network, make sure that the current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T operation.
CHAPTER 3 | Installing the Switch Equipment Checklist EQUIPMENT CHECKLIST After unpacking this 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.
CHAPTER 3 Mounting | Installing the Switch MOUNTING The switch 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.
CHAPTER 3 | Installing the Switch Mounting Figure 13: Attaching the Brackets 2. Mount the device in the rack, using four rack-mounting screws (not provided).
CHAPTER 3 Mounting 3. | Installing the Switch If installing a single switch only, turn to “Connecting to a Power Source” on page 51. 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. Attach the four adhesive feet to the bottom of the first switch. Figure 15: Attaching the Adhesive Feet 2.
CHAPTER 3 | Installing the Switch Installing an Optional Module into the Switch INSTALLING AN OPTIONAL MODULE INTO THE SWITCH Figure 16: Installing an Optional Module NOTE: The slide-in modules are hot-swappable, you do not need to power off the switch before installing or removing a module. To install an optional module into the switch, do the following: 1. Remove the blank metal plate (or a previously installed module) from the appropriate slot by removing the two screws with a flat-head screwdriver.
CHAPTER 3 | Installing the Switch Installing an Optional SFP Transceiver INSTALLING AN OPTIONAL SFP TRANSCEIVER Figure 17: 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.
CHAPTER 3 | Installing the Switch Connecting Switches in a Stack CONNECTING SWITCHES IN A STACK Figure 18 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.
CHAPTER 3 | Installing the Switch Connecting Switches in a Stack Figure 18: Making Stacking Connections 5. 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.
CHAPTER 3 | Installing the Switch Connecting to a Power Source should manually replace the failed link or unit as soon as possible. If you are using a wrap-around stack topology, a single point of failure in the stack will not cause the stack to fail. It would take two or more points of failure to break the stack apart. If the Master unit fails or is powered off, the backup unit will take control of the stack without any loss of configuration settings.
CHAPTER 3 | Installing the Switch Connecting to the Console Port 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. The on-board configuration program can be accessed from a terminal or a PC running a terminal emulation program.

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.
CHAPTER 4 | Making Network Connections Twisted-Pair Devices 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 21: Making Twisted-Pair Connections 2. If the device is a network 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 the section “Network Wiring Connections” on page 57.
CHAPTER 4 | Making Network Connections Twisted-Pair Devices 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.

CHAPTER 4 | Making Network Connections Fiber Optic SFP Devices WARNING: This switch uses lasers to transmit signals over fiber optic cable. The lasers are compliant with the requirements of a Class 1 Laser Product and are inherently eye safe in normal operation. However, you should never look directly at a transmit port when it is powered on.
CHAPTER 4 | Making Network Connections Fiber Optic SFP Devices The 1000BASE-SX, 1000BASE-LX, 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 64.
CHAPTER 4 | Making Network Connections 10 Gbps Fiber Optic Connections 10 GBPS FIBER OPTIC CONNECTIONS An optional 10 Gigabit transceiver (XFP) can be used for a backbone connection between switches. Single-mode fiber ports require 9/125 micron single-mode fiber optic cable. Multimode fiber optic ports require 50/125 or 62.5/125 micron multimode fiber optic cable. Each fiber optic cable must have an LC connector attached at both ends.
CHAPTER 4 | Making Network Connections 10 Gbps Fiber Optic Connections Figure 24: Connecting to an XFP Transceiver 4. As a connection is made, check the Link LED on the module to be sure that the connection is valid. The 10G fiber optic ports operate at 10 Gbps full duplex. The maximum length for fiber optic cable operating at 10 Gbps will depend on the fiber type as listed under “10 Gbps Ethernet Collision Domain” on page 63.
CHAPTER 4 | Making Network Connections Connectivity Rules 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.

Green Off Internal power functioning normally; RPU not plugged in. Amber Green Internal power faulty; RPU delivering power.
CHAPTER A | Troubleshooting Power and Cooling Problems 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. If you still cannot isolate the problem, the internal power supply may be defective.
CHAPTER A | Troubleshooting Stack Troubleshooting 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.
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. CAUTION: DO NOT plug a phone jack connector into any RJ-45 port.
CHAPTER B | Cables Twisted-Pair Cable and Pin Assignments 10BASE-T/100BASE-TX PIN ASSIGNMENTS Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).
CHAPTER B | Cables Twisted-Pair Cable and Pin Assignments Figure 26: Straight-through Wiring EIA/TIA 568B RJ-45 Wiring Standard 10/100BASE-TX Straight-through Cable White/Orange Stripe Orange End A White/Green Stripe 1 2 3 4 5 6 7 8 Blue White/Blue Stripe Green White/Brown Stripe 1 2 3 4 5 6 7 8 End B Brown CROSSOVER WIRING If the twisted-pair cable is to join two ports and either both ports are labeled with an “X” (MDI-X) or neither port is labeled with an “X” (MDI), a crossover must be implemented
CHAPTER B | Cables Twisted-Pair Cable and Pin Assignments 1000BASE-T PIN ASSIGNMENTS All 1000BASE-T ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports require that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are used for both transmit and receive.
CHAPTER B | Cables Fiber Standards ADJUSTING EXISTING CATEGORY 5 CABLING TO RUN 1000BASE-T If your existing Category 5 installation does not meet one of the test parameters for 1000BASE-T, there are basically three measures that can be applied to try and correct the problem: 1. Replace any Category 5 patch cables with high-performance Category 5e or Category 6 cables. 2. Reduce the number of connectors used in the link. 3. Reconnect some of the connectors in the link.
