Switch as a Segmentation Switch The example in Figure 7 shows how a Switch 3300 SM/XM stack can segment a network of shared 10Mbps and 100Mbps and 1000Mbps connections.
1697ua.bk Page 19 Monday, December 3, 2001 11:31 AM Network Configuration Examples Switch as a Collapsed Backbone Switch 19 The example in Figure 8 shows how a Switch 3300 TM stack can act as a backbone for both shared and switched network segments.
1697ua.bk Page 20 Monday, December 3, 2001 11:31 AM 20 CHAPTER 1: INTRODUCING THE SWITCH 3300 XM, SM, TM, MM Switch as a Desktop Switch The example in Figure 9 shows how the Switch can be used for a group of users that require dedicated 10Mbps or 100Mbps connections to the desktop. The 3300 SM Switch provides a Gigabit Ethernet connection to a SuperStack II Switch 4900 in the basement and the 3300 TM Switch provides a Gigabit Ethernet connection to a local server.
1697ua.bk Page 21 Monday, December 3, 2001 11:31 AM Configuration Rules for Fast Ethernet Configuration Rules for Fast Ethernet 21 The topology rules for 100Mbps Fast Ethernet are slightly different to those for 10Mbps Ethernet. Figure 10 illustrates the key topology rules and provides examples of how they allow for large-scale Fast Ethernet networks.
1697ua.bk Page 22 Monday, December 3, 2001 11:31 AM 22 CHAPTER 1: INTRODUCING THE SWITCH 3300 XM, SM, TM, MM 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.
1697ua.bk Page 23 Monday, December 3, 2001 11:31 AM Configuration Rules for Gigabit Ethernet (SM and TM) Configuration Rules for Gigabit Ethernet (SM and TM) 23 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.

1697ua.bk Page 25 Monday, December 3, 2001 11:31 AM 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.
1697ua.bk Page 26 Monday, December 3, 2001 11:31 AM 26 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.
1697ua.bk Page 27 Monday, December 3, 2001 11:31 AM Rack-mounting Rack-mounting 27 The Switch is 1U high and fits in most standard 19-inch racks. CAUTION: Disconnect all cables from the Switch before continuing. Remove all self adhesive pads from the underside of the Switch if they have been fitted. 1 Place the Switch the right way up on a hard flat surface, with the front facing towards you. 2 Locate a mounting bracket over the mounting holes on one side of the Switch, as shown in Figure 11.
1697ua.bk Page 28 Monday, December 3, 2001 11:31 AM 28 CHAPTER 2: INSTALLING THE SWITCH Placing Units On Top of Each Other If the Switch units are free-standing, up to four units can be placed one on top of the other. If you are mixing a variety of SuperStack Switch and Hub units, the smaller units must be positioned at the top. If you are placing Switch units one on top of the other, you must use the self-adhesive rubber pads supplied.
1697ua.bk Page 29 Monday, December 3, 2001 11:31 AM Stacking Units Stacking Units 29 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 SM, TM and XM 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.
1697ua.bk Page 30 Monday, December 3, 2001 11:31 AM 30 CHAPTER 2: INSTALLING THE SWITCH Figure 12 A stack of two units Stacking Up To Four Units You can stack up to four Switch units using one Switch 3300 MM and the appropriate number of Matrix Cables. Only one SuperStack 3 Switch 3300 MM unit can be fitted per stack. To stack up to four Switch units: 1 Power-off all the units. 2 Arrange the units as required.
1697ua.bk Page 31 Monday, December 3, 2001 11:31 AM Stacking Units 31 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 34.
1697ua.bk Page 32 Monday, December 3, 2001 11:31 AM 32 CHAPTER 2: INSTALLING THE SWITCH The Power-up Sequence Connecting a Redundant Power System The following sections describe how to get your Switch 3300 XM, SM, TM or MM 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.
1697ua.bk Page 33 Monday, December 3, 2001 11:31 AM Choosing the Correct Cables 33 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.
