Network Configuration Examples 17 Network Configuration Examples The following illustrations show some examples of how the Switch can be used in your network. Switch 3300 XM as a Segmentation Switch The example in Figure 3 shows how a Switch 3300 XM stack can segment a network of shared 10Mbps and 100Mbps connections. There is a 10/100 shared segment on each floor, and these segments are connected to the Switch which is positioned in the basement.
CHAPTER 1: INTRODUCING THE SWITCH 3300 XM Switch 3300 XM as a Collapsed Backbone Switch The example in Figure 4 shows how a Switch 3300 XM stack can act as a backbone for both shared and switched network segments.
Network Configuration Examples Switch 3300 XM as a Desktop Switch 19 The example in Figure 5 shows how a Switch 3300 XM can be used, within a stack, for a group of users that require dedicated 10Mbps or 100Mbps connections to the desktop. The Switch 3300 SM provides a Gigabit Ethernet connection to a SuperStack II Switch 9300 in the basement whilst the Switch 3300 TM provides a Gigabit Ethernet connection to a local server.
CHAPTER 1: INTRODUCING THE SWITCH 3300 XM Configuration Rules for Fast Ethernet The topology rules for 100Mbps Fast Ethernet are slightly different to those for 10Mbps Ethernet. Figure 6 illustrates the key topology rules and provides examples of how they allow for large-scale Fast Ethernet networks.
Configuration Rules with Full Duplex 21 The key topology rules are: Configuration Rules with Full Duplex ■ Maximum UTP cable length is 100m (328ft) over Category 5 cable. ■ A 412m (1352ft) fiber run is allowed for connecting switch-to-switch, or endstation-to-switch, using half-duplex 100BASE-FX. ■ A total network span of 325m (1066ft) is allowed in single-repeater topologies (one hub stack per wiring closet with a fiber run to the collapsed backbone).
CHAPTER 1: INTRODUCING THE SWITCH 3300 XM
2 INSTALLING THE SWITCH This chapter contains the information you need to install and set up the Switch. It covers the following topics: ■ Choosing a Suitable Site ■ Rack-mounting ■ Placing Units On Top of Each Other ■ Stacking Units ■ The Power-up Sequence ■ Choosing the Correct Cables ■ Solving Problems Indicated by LEDs ■ Managing the Switch WARNING: Safety Information.
CHAPTER 2: INSTALLING THE SWITCH Choosing a Suitable Site The Switch is suited for use in an office environment where it can be mounted in a standard 19-inch equipment rack, or free standing. Alternatively, the Switch can be rack-mounted in a wiring closet or equipment room. A rack-mounting kit, containing two mounting brackets and four screws, is supplied with the Switch.
Placing Units On Top of Each Other 25 Figure 7 Fitting a bracket for rack mounting 3 Insert the two screws and tighten with a suitable screwdriver. You must use the screws supplied with the mounting brackets. Damage caused to the unit by using incorrect screws invalidates your warranty. 4 Repeat steps 2 and 3 for the other side of the Switch. 5 Insert the Switch into the 19-inch rack and secure with suitable screws (not provided). Ensure that ventilation holes are not obstructed.
CHAPTER 2: INSTALLING THE SWITCH Stacking Units Units in the Switch 1100/3300 family can be stacked together and then treated as a single manageable unit with one IP address. The Matrix Port on the rear of the Switch allows you to connect two Switch units back-to-back. For this you need a Matrix Cable (part number 3C16965). Contact your supplier for details. The Switches in a stack are numbered 1 to 4, from the bottom up, for management purposes.
Stacking Units 27 Figure 8 A stack of two units Stacking Up To Four Units You can stack up to four Switch units using a Switch 3300 MM and the appropriate number of Matrix Cables. You need only one SuperStack 3 Switch 3300 MM per stack. To stack up to four Switch units: 1 Power-off all the units. 2 Arrange the units as required.
CHAPTER 2: INSTALLING THE SWITCH 4 If you use the management software of the units: ■ Ensure that all the units have the same version of management software ■ Ensure that you re-configure the stack-wide features on all the units For more information about management software, see “Managing the Switch” on page 32.
The Power-up Sequence The Power-up Sequence Connecting a Redundant Power System 29 The following sections describe how to get your Switch 3300 XM powered-up and ready for operation. You can connect a SuperStack Advanced Redundant Power System (part number 3C16071B) to the Switch. This unit, which is also known as an ARPS, is designed to maintain the power to your Switch if a power supply failure occurs. For normal redundancy, the unit requires one Type 2A Power Module.
CHAPTER 2: INSTALLING THE SWITCH Table 4 LED colors Color State Green The Switch is powered-up and operating normally Yellow The Switch has failed its Power On Self Test. This occurs if any of the ports fail during power-up. Off The Switch is not receiving power. If there is evidence of a problem, see “Solving Problems Indicated by LEDs” on page 31. Choosing the Correct Cables All of the ports on the front of the Switch 3300 XM are configured as MDIX (cross-over).
Solving Problems Indicated by LEDs Solving Problems Indicated by LEDs 31 If the LEDs on the Switch indicate a problem, refer to Table 5 which contains a list of problems and suggested solutions. Table 5 Problems indicated by LEDs Problem Suggested Solution A Power LED does not light Check that the power cable is firmly connected to the relevant Switch unit and to the supply outlet. If the connection is secure and there is still no power, you may have a faulty power cord.
CHAPTER 2: INSTALLING THE SWITCH Managing the Switch The Switch contains software that allows you to change and monitor the way it works. This management software is not required to get the Switch working, but if you do use it, you may improve the efficiency of the Switch and therefore improve the overall performance of your network. For information on managing the Switch using the management software, refer to the “SuperStack Switch Management Guide”.

GLOSSARY bridge A device that interconnects two LANs of a different type to form a single logical network that comprises of two network segments. Bridges learn which endstations are on which network segment by examining the source addresses of packets. They then use this information to forward packets based on their destination address. This process is known as filtering. broadcast A packet sent to all devices on a network.
flow control A congestion control mechanism. Congestion is caused by devices sending traffic to already overloaded port on a Switch. Flow control prevents packet loss and inhibits devices from generating more traffic until the period of congestion ends. full duplex A system that allows packets to be transmitted and received at the same time and, in effect, doubles the potential throughput of a link. half duplex A system that allows packets to transmitted and received, but not at the same time.
GLOSSARY line speed See baud. loop An event that occurs when two network devices are connected by more than one path, thereby causing packets to repeatedly cycle around the network and not reach their destination. MAC Media Access Control. A protocol specified by the IEEE for determining which devices have access to a network at any one time. MAC address Media Access Control address; also called hardware or physical address. A layer 2 address associated with a particular network device.
server SLIP SNMP stack STP SuperStack switch Switch Database TCP/IP A computer in a network that is shared by multiple endstations. Servers provide endstations with access to shared network services such as computer files and printer queues. Serial Line Internet Protocol. A protocol that allows IP to run over a serial line (console port) connection. Simple Network Management Protocol. The current IETF standard protocol for managing devices on an TCP/IP network.
GLOSSARY unicast WAN A packet sent to a single endstation on a network. Wide Area Network. A communications network that covers a wide area. A WAN can cover a large geographic area, and may contain several LANs within it.
