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 This 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. Collapsed Backbone This switch is an excellent choice for mixed Ethernet and Fast Ethernet installations where significant growth is expected in the near future. You can easily build on this basic configuration, adding direct full-duplex connections to workstations or servers.
Application Examples Central Wiring Closet With 26 parallel bridging ports (i.e., 26 distinct collision domains), this switch can collapse a complex network down into a single efficient bridged node, increasing overall bandwidth and throughput. In the figure below, the 10BASE-T/100BASE-TX ports on the switch are providing 100 Mbps connectivity for up to 24 segments. In addition, the switch is also connecting servers at 100 Mbps. Module 2 Module 1 Server Farm 10/100 Mbps Segments ... ... Figure 2-2.
Network Planning Making VLAN Connections VLANs can be based on port groups, or each data frame can be explicitly tagged to identify the VLAN group to which it belongs. When using port-based VLANs, ports can either be assigned to one specific group or to all groups. Port-based VLANs are suitable for small networks. A single switch can be easily configured to support several VLAN groups for various organizational entities (such as Finance and Marketing).
Connectivity Rules Connectivity Rules When adding hubs (repeaters) to your network, please follow the connectivity rules listed below for Ethernet, Fast Ethernet, or Gigabit Ethernet. 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.
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. When a switch is connected to a hub or any kind of shared media, you may want to turn off back pressure flow control to prevent jamming packets from being propagated thoughout the hub. 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.
Installing the Switch Optional Rack-Mounting Equipment If you plan to rack-mount the switch, be sure to have the following equipment available: • Four mounting screws for each device you plan to install in a rack—these are not included • A screwdriver (Phillips or flathead, depending on the type of screws used) 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.

If installing multiple switches, mount them in the rack, one below the other, in any order.
Installing the Switch 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.
Installing a GBIC Transceiver 5. Holding the module level, guide it into the carrier rails on each side and gently push it all the way into the slot, ensuring that it firmly engages with the connector. Installing a GBIC Transceiver 1000B ASE-X GBIC Modul e Modu le 1 Link PWR Duple x Diag M1 M2 RPU Stack Figure 3-5. Installing a GBIC Transceiver You can install a GBIC transceiver as described below: 1. Insert the transceiver with the SC connector facing out toward you.
Installing the Switch Connecting to the Stack’s Backplane Plug one end of the stack cable (ordered separately) in the TX (right) port of the top unit and the other end to the RX (left) port of the next unit. Repeat this step for each unit in the stack. Form a simple chain starting at the TX port on the top unit and ending at the RX port on the bottom unit (stacking up to 8 units).
Connecting to a Power Source 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 3-7. Power Receptacle 2. Plug the other end of the cable into a grounded, 3-pin socket. Note: 3. 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.

Chapter 4: Making Network Connections Connecting Network Devices The switch may be connected to 10 or 100 Mbps network cards in PCs and servers, as well as to Ethernet and Fast Ethernet hubs and switches. It may also be connected to remote devices using the optional fiber optic modules. Twisted-Pair Devices Each device requires a shielded or unshielded twisted-pair (STP or UTP) cable with RJ-45 connectors at both ends.
Making Network Connections Connecting to PCs, Servers, Hubs and Switches 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. 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector. Figure 4-1.

Cables Twisted-Pair Cable and Pin Assignments Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards. For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be red and the other, red with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.
1000BASE-T Pin Assignments Straight-Through Wiring If the twisted-pair cable is to join two ports and only one of the ports has an internal crossover (MDI-X), the two pairs of wires must be straight-through. (When auto-negotiation is enabled for any RJ-45 port on this switch, you can use either straight-through or crossover cable to connect to any device type.

1000BASE-T Cable Requirements 1000BASE-T Cable Requirements All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable installations, Category 5e (enhanced Category 5) or 6 cable should be used. The Category 5e and 6 specification includes test parameters that are only recommendations for Category 5.
