This chapter contains:
■ An overview of the CoreBuilder
®
9400 system and
how it provides solutions for your network
■ A description of the major features and
components of the system
■ A network configuration example
CoreBuilder 9400 Intelligent Switch
The CoreBuilder 9400 system delivers full line rate
switching among all 24 Gigabit Ethernet ports. The
system has the following ports (shown in Figure 1 on
page 15):
■ 12 1000BASE-SX (MMF) ports with SC connectors
■ 12 GBIC ports that can accept 1000BASE-LX or
1000BASE-SX GBIC transceivers
The system supports full-duplex mode on all Gigabit
Ethernet ports and up to 32,000 MAC addresses. To
deliver even higher performance rates among
switches, the system supports trunking, which allows
you to group up to six Gigabit Ethernet ports into a
single multigigabit connection for a maximum of
12 trunks per system.
System Features and Benefits
The CoreBuilder 9400 is part of 3Com’s CoreBuilder
family. To combine technologies as your network
grows, install the CoreBuilder 9400 in your network.
Some key features of the CoreBuilder 9400 system:
■ High-density Gigabit Ethernet configuration
This system exhibits no packet loss or delays even
under maximum network traffic on its 24 Gigabit
Ethernet ports.
■ Trunking of Gigabit Ethernet ports
This system allows you to configure up to six
Gigabit Ethernet ports into a single multigigabit
connection for a maximum of 12 trunks per unit.
■ Trunking links and Spanning Tree Protocol support
The CoreBuilder 9400 protects against cable and
equipment failures with Spanning Tree Protocol
and trunking links.
■ Failure protection
To protect your network, this system has an
optional second power supply.
