Summary of Features

Network managers are currently faced with the challenge of creating networks that can provide high-speed and high performance to serve the needs of today’s network users.

Part of the 3Com SuperStack

II range of products, the Switch 9000

provides switching between multiple Gigabit Ethernet ports.

The Switch 9000 has the following features:

■ Eight Gigabit Ethernet ports

■ Support for 12,000 addresses in the Switch forwarding database

■ Fully nonblocking operation

■ All ports transmit and receive packets at wire speed

■ Full duplex operation

■ 4Mb packet memory

1-2 CHAPTER 1: SWITCH 9000 OVERVIEW

■ Virtual LANs (VLANs)

■ Support for 64 VLANs on a single Switch 9000

■ Support for IEEE 802.1Q tagging

■ Controls trafﬁc (including broadcasts)

■ Provides extra security

■ Protocol-sensitive ﬁltering for VLANs

■ Recognition of the Priority Access Control Enabled (PACE) bit set by

3Com Etherlink

■ Responds to 802.3x ﬂow-control messages

■ Auto-negotiation to IEEE 802.3z for plug and play

■ Load sharing

■ Easy software upgrades

■ BOOTP for automatic Internet Protocol (IP) address conﬁguration

■ Local management

Port Connections The Switch 9000 provides eight 850nm ﬁber-optic Gigabit Ethernet

ports, using duplex SC connectors. Using the eight ports, you can connect other Gigabit Ethernet devices (such as 10/100 switches that have Gigabit Ethernet modules) to the Switch 9000. You can also connect Switch 9000 devices to each other.

Summary of Features 1-3

Full Duplex The Switch 9000 provides full-duplex support for all ports. Full-duplex

allows frames to be transmitted and received simultaneously and, in effect, doubles the bandwidth available on a link. The Switch 9000 will refuse a half duplex connection on any port.

Switch Operation The Switch 9000 uses the same algorithm as a conventional 802.1d

bridge for ﬁltering, forwarding, and learning packets.

Virtual LANs (VLANs)

The Switch 9000 has a Virtual LAN (VLAN) feature that allows you to build your network segments without being restricted by physical connections. A VLAN is a group of location- and topology-independent devices that communicate as if they are on the same physical Local Area Network (LAN). Implementing VLANs on your network has the following three advantages:

■ It eases the change and movement of devices on networks. If a

device in VLAN marketing is moved to a port in another part of the network, all you must do is specify that the new port belongs to VLAN marketing.

■ It helps to control broadcast trafﬁc. If a device in VLAN marketing

transmits a broadcast frame, only VLAN marketing devices receive the frame.

■ It provides extra security. Devices in VLAN marketing can only

communicate with devices on VLAN sales using a device that provides routing services.

For more information on VLANs, refer to Chapter 5.

Priority Access Control Enabled (PACE)

The Switch recognizes the PACE bit set by 3Com Etherlink

adapters and other devices supporting PACE. When enabled, trafﬁc with these bits receives priority service from the Switch.

Spanning Tree Protocol

(STP)

The Switch 9000 supports the IEEE 802.1d Spanning Tree Protocol (STP) which is a bridge-based mechanism for providing fault tolerance on networks. STP allows you to implement parallel paths for network trafﬁc, and ensure the following:

1-4 CHAPTER 1: SWITCH 9000 OVERVIEW

■ Redundant paths are disabled when the main paths are operational.

■ Redundant paths are enabled if the main trafﬁc paths fail.

For more information on STP, refer to Chapter 7.

IP Unicast Routing

The Switch 9000 can route IP trafﬁc between the VLANs conﬁgured as virtual router interfaces. Both dynamic and static IP routes are maintained in the routing table. RIP version 1 and RIP version 2 are supported.

For more information on IP unicast routing, refer to Chapter 8.

Network Conﬁguration Example

This section describes where to position the Switch 9000 within your network. One common use of the Switch 9000 is on a Gigabit Ethernet backbone. Figure 1-1 shows an example of a Gigabit Ethernet backbone within a building.

Network Configuration Example 1-5

Figure 1-1 Switch 9000 used in a backbone conﬁguration

The Switch 3000 on each ﬂoor is provided with a Gigabit Ethernet full-duplex link to the Switch 9000.

Using Gigabit Ethernet as a backbone technology removes bottlenecks by providing scalable bandwidth, low-latency, high-speed data switching.

In addition to providing a fast backbone between Ethernet LANs, Gigabit Ethernet equipped ﬁle servers and services may be directly

INSTALLATION AND SETUP

This chapter describes the following:

■ How to decide where to install the Switch 9000

■ Gigabit Ethernet conﬁguration rules

■ How to install the Switch in a rack or free-standing

■ How to connect equipment to the console port

■ How to check the installation using the Power On Self-Test (POST)

Following Safety Information

Determining the Switch 9000 Location

Before installing or removing any components of the Switch, or before carrying out any maintenance procedures, you must read the safety information provided in Appendix A of this guide.

The Switch 9000 is suited for use in the ofﬁce, where it can be free-standing or mounted in a standard 19-inch equipment rack. Alternatively, the device can be rack-mounted in a wiring closet or equipment room. Two mounting brackets are supplied with the Switch.

CAUTION: When using a rack mounting system, the Switch must be mounted on a shelf or runners. The rack mounting brackets alone are not sufﬁcient to support the weight of the Switch. The rack mounting brackets are provided to ensure stability across the horizontal plane. If you stack Switches, you must ensure that the shelf or runners are strong enough to hold the combined weight. Ensure that the ventilation holes are not obstructed.

After deciding where to install the Switch, make sure that:

■ You will be able to meet the conﬁguration rules detailed in

Chapter 1.

■ The Switch is accessible and cables can be connected easily.

2-2 CHAPTER 2: INSTALLATION AND SETUP

■ Water or moisture cannot enter the case of the unit.

■ Temperature must be within the range of 0 to 40 degrees Celsius.

■ Air-ﬂow around the unit and through the vents in the side of the

case is not restricted. You should provide a minimum of 25mm (1-inch) clearance.

■ No objects are placed on top of the unit.

■ Units are not stacked more than four high if the Switch is

free-standing.

Conﬁguration Rules

for Gigabit Ethernet

Installing the Switch 9000

Rack Mounting The Switch 9000 is 2U high and will ﬁt in most standard 19-inch racks.

The connectors, supported media types, and maximum distances for the Switch 9000 are described in Chapter 1.

The Switch 9000 can be mounted in a rack, or placed free-standing on a tabletop.

The Switch should only be used in a rack if it is mounted on runners, a shelf, or a tray to support the weight. The rack mount kits alone are not sufﬁcient to support the weight of the Switch.

CAUTION: The rack mount kits must not be used to suspend the Switch from under a table or desk, or attach it to a wall.

To install the mounting brackets on the Switch, follow these steps:

1 Place the Switch the right way up on a hard ﬂat surface, with the front

facing toward you.

2 Remove the existing screws from the sides of the chassis. 3 Locate a mounting bracket over the mounting holes on one side of the

unit.

4 Insert the four screws and fully tighten with a suitable screwdriver, as

shown in Figure 2-1.
