Power Supplies

The Switch 4007 can contain two back-loading, 930-watt, modular AC power supplies (Model Number 3CB9EP9). The power supplies provide power to the management modules, switch fabric module, interface modules, fans, and backplane.

Figure 3 shows a 930-watt AC power supply in a Switch 4007 chassis.

930-watt AC Power Supply

Switch 4007 power supplies are autosensing. Each power supply (Figure 3) can automatically sense the type of input voltage to which it is being connected at the electrical outlet.

The power supplies are load sharing in that all power supplies provide an equal amount of the load current. Each 930-watt power supply has its own power cord and is shipped separately from the chassis. The type of power cord depends on your country location.

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.

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.

Management Modules

The Switch 4007 chassis contains two slots (slots 8 and 9) for Management Modules management modules. These modules do not occupy module payload slots. Figure 8 shows the front panel.

Figure 8

You can communicate through an RS-232 connector (for connection to a terminal) or an RJ-45 port (for connection to Ethernet networks) on the front panel of the EME to configure and report on switch and module operation.

The Switch 4007 EME is an SNMP-based network management module that allows you to configure and manage the Switch 4007 chassis and modules. The EME backplane services generate, control, and monitor the Switch. The management modules provide power management functions.

Fast Ethernet Modules

The frame-based switching modules are intelligent Layer 2 and Layer 3 modules that have their own embedded agent. These modules are physically connected to the backplane ports of the switch fabric module in the chassis. These modules switch between the front panel ports and the backplane ports. Switching interface modules provide network connectivity functions.

Fast Ethernet Interface Modules are available in these port configurations:

Gigabit Ethernet Modules

The Gigabit Ethernet (GEN) Interface Modules are two-port interface modules for the 3Com Switch 4007. The GEN interface modules serve as a 2–Gigabit data channel between the Gigabit Ethernet Switch Fabric Module and other 802.3z–compliant Gigabit Ethernet devices. GEN Interface Modules use SC connectors.

Because Gigabit Ethernet interface modules are not intelligent, you cannot access them directly; all communication takes place through the switch fabric module. GEN interface modules serve as a two-Gigabit data channel between the GEN Switch Fabric Module and other 802.3z-compliant Ethernet devices.

For information about how to install these modules, see the module’s with each module.

Gigabit Ethernet Interface Modules are available in these port configurations:

GBIC Transceivers

The Gigabit Interface Converter (GBIC) ports on your system connect to Gigabit Ethernet networks through a GBIC transceiver (Figure 1), providing a high-speed connection over fiber-optic cable. The transceiver connects to the network using a fiber-optic duplex subscriber connector (SC). You can remove and replace the transceiver with the system powered on, which is called hot-swapping.

Management Access

You can access and manage your Switch 4007 modules using several methods:

Administration Console

■

Web Management suite of applications

■

External SNMP-based network management

■

application, such as Transcend Services

Network Control

The Administration Console and most of Web Management are embedded parts of the software and are available for immediate use to manage your modules.

Administration Console Access

To manage the module from the Administration Console:

For information about logging in to the EME, see the

Enterprise Management Engine User Guide.

At the prompt, enter:

connect <slot>.1

Where

<slot>

is the chassis slot number of the module that you want to manage, and the number after the decimal point is a subslot number (which is always 1).

The Administration Console displays the top-level menu prompt. For example, if you installed a 20-port 100BASE-FX Fast Ethernet Switching Module in slot 4, then the prompt appears as follows:

CB9000@4.1 [20-E/FEN-FX-L2] ():

Enter commands to manage the module.

For example, to display a module baseline, enter:

module baseline display

For more information about Administration Console module commands, see the multiplatform

Reference Guide.

Web Management Access

Web Management applications are an embedded part of the Switch 4007. They include Web Console, DeviceView, and Performance monitoring tools. Additional installable applications include online Help.

After you have set up your IP address for the Switch, you can access the Web Management applications directly in your Web browser by entering the IP address. For information about setting up your IP address, see the

Quick Start Guide

Enterprise Management Engine
