1 SYSTEM AND SETUP OVERVIEW This chapter contains: s An overview of the CoreBuilder® 9400 system and how it provides solutions for your network s A description of the major features and components of the system s 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): s 12 1000BASE-SX (MMF) ports with SC connectors s 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: s High-density Gigabit Ethernet configuration This system exhibits no packet loss or delays even under maximum network traffic on its 24 Gigabit Ethernet ports. s 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. s Trunking links and Spanning Tree Protocol support The CoreBuilder 9400 protects against cable and equipment failures with Spanning Tree Protocol and trunking links. s Failure protection To protect your network, this system has an optional second power supply.
