information:

■

SNMP Network Manager documents

The Switch 9300 uses SNMP (Simple Network

Management Protocol), which can be accessed by

a remote network management application. 3Com

has network management applications for a

variety of platforms. Contact your network

supplier for current product information. Each

network management application includes a guide

that explains how to manage your system.

If you are using network management software

from another vendor, refer to the sections of the

product’s documentation that describe how to

manage SNMP devices.

This chapter contains:

■ An overview of the SuperStack

II Switch 9300

and how it provides solutions for your network

■ A description of the major features and

components of the system

■ A network configuration example

Switch 9300 Intelligent Switch

The SuperStack II Switch 9300 family delivers full line

rate, nonblocking switching among all 12 Gigabit

Ethernet ports. The three models give you options for

using multimode (MMF) or single-mode (SMF) fiber:

■

3C93010

— 12 1000BASE-LX ports (MMF or SMF)

for fiber with SC connectors. See Figure 1.

■

3C93011

— 10 1000BASE-SX (MMF) ports plus 2

1000BASE-LX ports (MMF or SMF) for fiber with

SC connectors. See Figure 2.

■

3C93012

— 12 1000BASE-SX ports (MMF) for

fiber with SC connectors. See Figure 1.

The Switch 9300 supports full-duplex mode on all

Gigabit Ethernet ports and up to 16,000 MAC

addresses. To deliver even higher performance rates

among switches, the Switch 9300 supports trunking,

which allows combining up to six Gigabit Ethernet

ports into a single multigigabit connection.

System Features and Benefits

The Switch 9300 is part of 3Com’s SuperStack family.

To combine technologies as your network grows,

install the Switch 9300 in a SuperStack network.

Some key features of the Switch 9300 system:

■ High-density Gigabit Ethernet configuration

The SuperStack II Switch 9300 exhibits no packet

loss or delays even under maximum network traffic

on its 12 Gigabit Ethernet ports.

■ Trunking of Gigabit Ethernet ports

The Switch 9300 allows you to choose

performance-level links between switches, with up

to 6 Gigabits of bandwidth.

■ Resilient Links

Resilient links protect your network against an

individual link or device failure by providing a

secondary backup link that is inactive until needed.

■ Trunking links, Spanning Tree Protocol, and

Advanced Redundant Power System (RPS) support

The Switch 9300 protects against cable and

equipment failures with Spanning Tree Protocol

and trunking links. The SuperStack II Advanced RPS

protects against power interruptions for

fault-tolerant networks. See Figure 3.

Manageability

The Switch 9300 provides full support for VLANs

and RMON Version 1, as well as a roving analysis

port through SNMP management.

Switch 9300 System Management

Switch 9300 systems include integrated management

to provide fault tolerance and maximum network

availability. This management is accessible in two

ways:

■

Switch 9300 Administration Console

■

Standard network managers based on SNMP, such

as 3Com’s Transcend

®

Network Control Services,

Sun’s SunNet Manager, HP OpenView, and IBM’s

NetView AIX applications

Network Configuration Example

This section discusses one way to place the

Switch 9300 in your network.

Speeding Up Server Access

To centralize your servers for easier service and

support, use a configuration like the one in Figure 4.

Suppose all of your organization’s servers are located

in the same physical space. These servers must

support a large number of clients that are distributed

throughout the organization’s campus. The client

connections are switched Fast Ethernet.

You can multiplex the traffic from each grouping of

desktop clients into one higher-bandwidth stream

through a SuperStack II Switch 3900.

Each Switch 3900 can, in turn, pass its traffic along to

a Switch 9300, which multiplexes the traffic into

Gigabit Ethernet streams for the servers.

This architecture eliminates bottlenecks that are

caused by each Fast Ethernet device as it vies for

access to the server.

You can also use the Switch 9300 for many other

applications, such as to consolidate LAN backbones or

to provide more flexible trunking configurations.

Installing the System on a Table Top or in a

Free-Standing Stack

To install the Switch 9300 system on a table top or in

a free-standing stack, follow these instructions:

1

See Appendix B for site requirements.

2

Turn the system on its side.

3

Remove the protective covering from the rubber feet.

4

Place one rubber foot in each marked area at the four

corners of the unit.

5

Turn the system onto its feet.

6

Verify that the air intake vents and fan exhaust vents

at the sides of the system are not blocked.

To install the system into a free-standing stack, place

the system on top of another. Be sure that the rubber

feet of the upper unit fit securely in the recesses in

the top of the lower unit. See Figure 5.
