16954ua.book Page 11 Friday, April 30, 1999 9:39 AM 1 INTRODUCING THE SWITCH 610 This chapter contains introductory information about the Switch and how it can be used in your network.
16954ua.book Page 12 Friday, April 30, 1999 9:39 AM 12 CHAPTER 1: INTRODUCING THE SWITCH 610 About the SuperStack II Switch 610 The SuperStack® II system solves the problem of growth in dynamic network environments and provides everything you need for successful workgroup networking. Much more than a collection of stackable components, the system comprises a complete, integrated architecture of modular parts that are easy to install and use.
16954ua.book Page 13 Friday, April 30, 1999 9:39 AM Switch 610 — Front View Detail 13 Switch 610 — Front View Detail Figure 1 Switch 610 — Front view Port Connections 10BASE-T Ports The Switch has 24 10BASE-T ports configured as MDIX (cross-over). The maximum segment length is 100m (328ft) over Category 3, 4, or 5 twisted pair cable. As these ports are configured as MDIX (cross-over), you need to use a cross-over cable to connect to devices whose ports are MDIX-only.

Here switching is brought to the desktop with a single endstation per port. Local servers are connected via 100Mbps Fast Ethernet links.
16954ua.book Page 19 Friday, April 30, 1999 9:39 AM Configuration Rules for Fast Ethernet Configuration Rules for Fast Ethernet 19 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.
16954ua.book Page 20 Friday, April 30, 1999 9:39 AM 20 CHAPTER 1: INTRODUCING THE SWITCH 610 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.
16954ua.book Page 21 Friday, April 30, 1999 9:39 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 ■ The Power-up Sequence ■ Choosing the Correct Cables ■ Solving Problems Indicated by LEDs ■ Managing the Switch WARNING: Safety Information.
16954ua.book Page 22 Friday, April 30, 1999 9:39 AM 22 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 six screws, is supplied with the Switch.
16954ua.book Page 23 Friday, April 30, 1999 9:39 AM Placing Units On Top of Each Other 23 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).
16954ua.book Page 24 Friday, April 30, 1999 9:39 AM 24 CHAPTER 2: INSTALLING THE SWITCH The Power-up Sequence Connecting a Redundant Power System The following sections describe how to get your Switch 610 powered-up and ready for operation. You can connect a SuperStack II Advanced Redundant Power System (part number 3C16071) to the Switch. This unit, which is also known as an RPS, is designed to maintain the power to your Switch if a power supply failure occurs.
16954ua.book Page 25 Friday, April 30, 1999 9:39 AM Choosing the Correct Cables Choosing the Correct Cables 25 All of the ports on the front of the Switch 610 are configured as 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).
