■GBIC Transceivers

■Slot Restrictions

■Management Access

■Where to Go from Here

Overview

The 3Com® Switch 4007 is a high performance, high-density, aggregation switch. The Switch 4007 has a modular 7-slot chassis that contains slots for the following types of modules:

■Management Modules (see page 21)

The EME management module exchanges information with all modules through the management bus. The EME uses the management bus to send commands to all chassis modules and to collect information from interface modules.

The Switch 4007 is required to have a minimum of one EME (Enterprise Management Engine) management module. You can install a second EME for redundant management operation.

■Switch Fabric Modules (see page 20)

The Gigabit Ethernet (GEN) switch fabric module is the central backplane aggregator for the chassis. Switch fabric modules fit into slot 7 of the

Switch 4007 chassis.

■Fast Ethernet Modules (see page 22) and Gigabit Ethernet Modules (see page 23)

Interface modules pass data through the switch fabric module. The data may get sent back out to other modules or sent out through a switch fabric module front panel port to another device.

The Switch 4007 contains six slots for interface modules. Fast Ethernet or Gigabit Ethernet modules can occupy every slot except slot 7. The six interface modules access five 2 Gbps serial channels, which are wired to one dedicated switch fabric module slot.

20 CHAPTER 2: SWITCH 4007 MODULES

Switch Fabric Modules

The Switch 4007 supports 9-port and 24-port Gigabit Ethernet Switch Fabric modules. Both switch fabric modules fit into slot 7 of the Switch 4007 chassis.

3Com enables you to simplify your installation by selecting from four pre-configured starter kits.

■Fast Ethernet starter kits are pre-configured with one 9-port Switching Fabric (Model Number: 3CB9FG9) in slot 7.

■Gigabit Ethernet starter kits are pre-configured with one 24-port Switching Fabric (Model Number: 3CB9FG24T) in slot 7.

The Switch Fabric modules support the following key features:

■18 Gbps or 48 Gbps switching capacity

■Hot-swapping of modules

■IEEE 802.1D Spanning Tree Protocol bridging for Gigabit Ethernet

■Multicast packet firewall to limit broadcast storms

■Port trunking support for 12 groups, with up to six ports in a group

■IEEE 802.1Q VLAN tagging for up to 126 groups of port-based virtual LANs (VLANs)

■Embedded Simple Network Management Protocol (SNMP) management agent

■Support for four RMON-1 groups: Ethernet Statistics, History, Events, and Alarms

9-port Gigabit Ethernet Switch Fabric

Model Number: 3CB9FG9

The 9-port Gigabit Ethernet (GEN) Switch Fabric Module is optimized for use in wiring closets. The module has six non-blocking Gigabit Ethernet ports that connect directly to the chassis backplane to provide high-speed, low-latency connectivity between Switch 4007 interface modules. Its front panel features three non-blocking Gigabit Interface Converter (GBIC) interface ports that accept optional GBIC transceivers (see “GBIC Transceivers” on

page 25). Figure 6 shows the front panel.
