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).

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.

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:

Troubleshooting the Web Management Software

If you are unable to run the Web Management software, verify the accuracy of your environment variable.

CLASSPATH

By default, the Web Management installation adds two directories above your existing CLASSPATH: C:\3Com.

Your directories may be different if you did not select the default C:\3Com directory during installation.

If your system already has an existing

CLASSPATH

before you install the additional Web Management files, the necessary 3Com directories are added above yours. As a result, your classpath may look like this:

C:\3Com;C:\java\classes;C:\java\applets\myclasses;

If you modify your classpath and do not include the 3Com directories (and possibly if you do not list them before any other directories in your classpath), the Web Management components may fail to run properly.

In Windows 95, your CLASSPATH is set in the

autoexec.bat

SET CLASSPATH=C:\3Com;

file. It usually appears in this format:

Page 52

HAPTER

ANAGEMENT TOOLS

In Windows NT, your

CLASSPATH

CLASSPATH

Settings

This minimal setting is required for Web Management:

The following setting is also acceptable:

SET CLASSPATH=C:\3Com;C:\java\classes;

This setting can potentially cause problems:

SET CLASSPATH=C:\java\classes;C:\myclasses;C:\3Com;

The next setting results in unspecified behavior, because certain 3Com Web Management directories are not included. An unspecified

CLASSPATH

has similar results. In either case, the installed Web Management applications may fail to run:

High power capacity Determines the current power limit.

Intelligent Power Subsystem Features

Provides evenly distributed power consumption among all installed power supplies. Switch 4007 activity is not disrupted if a power supply fails because there is no changeover (and hence, no changeover interval).

Provides easy access for upgrades. As your power needs increase over time, it is easy to upgrade by adding a power supply into the rear of the 7-slot chassis.

Cools the power supply bay. Vent holes and fan trays reduce the possibility that an overheat condition in the power supply bay may cause or contribute to a failure of the chassis or its modules. This feature works with other switch features to maintain normal chassis internal operating temperature.

The power mode and the amount of power available determine the current power limit. The actual power that is delivered depends on whether you are running in non-fault-tolerant mode or in fault-tolerant mode.

Feature Description

Controller module-based, software-driven, power management

Intelligent Power Subsystem Features (continued)

Power Management

The Enterprise Management Engine (EME) works protects network integrity using power management. The EME determines how much power a Switch 4007 module requires before it permits the module to power on.

The EME manages power use in the chassis by:

Preventing newly installed modules from receiving

■

power when there is not enough power available.

Allowing you to prioritize the order in which

■

modules power off (if there is insufficient power available).

Confirms that there is enough power for a new Switch 4007 module.

Software-driven power management (Intelligent Power Management) also provides protection against the possibility of a catastrophic power failure. If the switch is operating in power fault-tolerant mode and a power supply fails, an installed EME powers off selected (low power class) Switch 4007 modules until the power deficit is corrected. Intelligent Power Management ensures that key components and resources continue to operate, even under extreme failure conditions.

Allowing you to implement fault-tolerant power,

■

which allows the chassis to reserve some of its power capacity to protect against a power supply failure.

To support redundancy, install one or more power supplies beyond the minimum number that is required to support the chassis and its modules (n + 1 redundancy).

Power Availability and Power Supply Capacity

This section explains the following concepts concerning power supply management:

Power available to modules

■

— The amount of power that is available to Switch 4007 modules is determined by the number of power supplies that are installed.

Power capacity of a power supply

■

— The power capacity of a power supply unit is the maximum amount of power that the power supply delivers.

When you manage power in your Switch, consider the system overhead, that is, the power that the Switch 4007 itself (including fans, signalling, and EMEs) consumes. Before you install any new module into a chassis, assess the power budget by calculating the total power requirements for all installed modules, fans, and management modules.

Page 69

Power Management

See the documentation that is supplied with each module to determine your module power requirements. Take into account any modules that you plan to install, as well as those that are already installed.

Power Supply Modes

The Switch 4007 runs in either of two power supply modes:

Fault-Tolerant Mode

■

Non-Fault Tolerant Mode

■

For optimal power redundancy in either power mode, run the Switch 4007 with two power supplies.

Fault-Tolerant Mode

A user-selectable mode in which power that is equivalent to one power supply is held in reserve. This reserve power is not available to installed modules until a power supply fails, or until you switch the power mode from power fault-tolerant mode to power non-fault-tolerant mode.

Rather, a factory-defined power limit (which is based on the number of installed power supplies) ensures that power that is equivalent to at least one power supply is available to replace power that is lost when a power supply fails.

The amount of power that installed modules in a

■

chassis require must not be greater than the number of installed power supplies, minus one (n-1). When you reserve power that is equivalent to one power supply in power fault-tolerant mode, the failure of a single power supply has no impact on installed modules that are already powered on.

If a power supply fails while the switch is running in power fault-tolerant mode:

EMEs respond by automatically disabling power

■

fault-tolerant mode.

Power formerly reserved (unavailable to installed

■

modules) is made available by power class and slot location to power-enabled Switch 4007 modules to prevent them from powering off (as an attempt to bring power consumption under the now-reduced power budget).

While the chassis is running in fault-tolerant mode:

All installed power supplies are functioning and

■

contributing power to the chassis and modules.

No single power supply is a dedicated standby power supply.

All modules that had power before the power

■

supply failure continue to receive power without interruption.

Upon power supply recovery, the EME

■

automatically reenables power fault-tolerant mode.

When you attempt to set the Switch 4007 to power fault-tolerant mode, EMEs determine if there is sufficient unallocated power budget available to place power that is equivalent to one power supply in reserve.

If there is insufficient unallocated power budget,

■

the Switch 4007 remains in power non-fault-tolerant mode.

To prevent management modules from automatically disabling power fault-tolerant mode in response to a power supply failure, ensure that two power supplies are installed. If a power supply failure occurs under any condition, an alert is sent to the management application.

While the switch is running in power non-fault-tolerant mode, the amount of power that is available to modules is determined by the number and type of power supplies that are installed.

If a power supply fails while the chassis is running in power non-fault-tolerant mode:
