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 SM as a Segmentation Switch The example in Figure 3 shows how a Switch 3300 SM stack can segment a network of shared 10Mbps,100Mbps and 1000Mbps 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 SM Switch 3300 SM as a Collapsed Backbone Switch The example in Figure 4 shows how a Switch 3300 SM stack can act as a backbone for both shared and switched network segments.
Network Configuration Examples Switch 3300 SM as a Desktop Switch 19 The example in Figure 5 shows how a Switch 3300 SM can be used, within a stack, for a group of users that require dedicated 10Mbps or 100Mbps connections to the desktop. The 3300 SM Switches provide a Gigabit Ethernet connection to a SuperStack II Switch 9300 in the basement and to a local server.
CHAPTER 1: INTRODUCING THE SWITCH 3300 SM 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 SM Configuration Rules for Gigabit Ethernet Gigabit Ethernet is designed to run over four media: ■ Single-mode fiber optic cable, with connections up to 5km. ■ Multimode fiber optic cable, with connections up to 550m. ■ Balanced, shielded copper cabling, with connections up to 25m. ■ Category 5 cabling, with connections up to 100m.
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 II 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 SM powered-up and ready for operation. You can connect a SuperStack II Advanced Redundant Power System (part number 3C16071A) 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 2 Power Module (part number 3C16074).
CHAPTER 2: INSTALLING THE SWITCH Table 5 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 SM 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 6 which contains a list of problems and suggested solutions. Table 6 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 II Switch Management Guide”.
