Network Configuration Examples Switch 3300 XM as a 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 Desktop Switch 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.
1: I 3300 XM HAPTER NTRODUCING THE WITCH Configuration Rules The topology rules for 100Mbps Fast Ethernet are slightly different to for Fast Ethernet 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 The key topology rules are: 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).

NSTALLING THE WITCH 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.
2: I HAPTER NSTALLING THE WITCH Choosing a Suitable The Switch is suited for use in an office environment where it can be Site 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.
Placing Units On Top of Each Other 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.
2: I HAPTER NSTALLING THE WITCH 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.
Stacking Units Figure 8 A stack of two units Stacking Up To Four You can stack up to four Switch units using a Switch 3300 MM and the Units 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.

MDIX (cross-over). If you want to make a connection to another MDIX port, you need a cross-over cable. Most of the 10BASE-T and 100BASE-TX ports on 3Com devices are MDIX-only. Many ports on workstations and servers are configured as MDI (straight-through). If you want to make a connection to an MDI port, you need to use a standard straight-through cable.
Solving Problems Indicated by LEDs Solving Problems If the LEDs on the Switch indicate a problem, refer to Table 5 which Indicated by LEDs contains a list of problems and suggested solutions. Table 5 Problems indicated by LEDs Problem Suggested Solution A Power LED does not Check that the power cable is firmly connected to the light...
2: I HAPTER NSTALLING THE WITCH Managing the The Switch contains software that allows you to change and monitor the Switch 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.
AFETY NFORMATION You must read the following safety information before carrying out any installation or removal of components, or any maintenance procedures on the Switch 3300 XM.
