■ Configurations — When you are logged in using

the Administer password, you can configure the

management module and monitor the chassis

environment.

This chapter contains:

■ EME Management Module Architecture

■ Switch 4007 Setup Wizard

■ Transcend Network Supervisor

■ Web Management Tools

■ Inventory — The management module provides a

complete inventory of switch contents, including

fans and power supplies. The inventory lists current

software revisions for all installed modules. The

inventory system also supports a scratchpad

feature so that you can add custom information to

the management module display.

EME Management Module Architecture

The Enterprise Management Engine (EME)

management module is the primary communication

mechanism into the chassis and any installed switch

fabric modules and interface modules.

■ SNMP Support — SNMP (Simple Network

Management Protocol) is a protocol that the

Internet Engineering Task Force defined. The

management module acts as an agent in an

SNMP-managed environment. The agent responds

to SNMP requests and generates SNMP traps.

The EME is an SNMP-based network management

module that manages and controls the Switch 4007

chassis and its modules.

■ Telnet Support — With the management module

telnet command, you can connect a

management module to any other Telnet device.

The management module also supports incoming

Telnet sessions so that you can manage a

management module from a workstation with

Telnet support, or from another management

module.

CHAPTER 5: MANAGEMENT TOOLS

■ In-Band and Out-of-Band Download — The

management module provides both in-band and

out-of-band downloads. In-band download uses

TFTP (Trivial File Transfer Protocol) through a

network connection. Out-of-band download uses

XMODEM software and the RS-232 serial port on

the front panel of the management module. The

management module allows you to download to

multiple modules using a single command.

Transcend Network Supervisor

3Com^®Transcend Network Supervisor, supplied on

the Software CD-ROM, provides easy-to-use network

management tuned to the needs of small to medium

enterprises. Network devices are automatically

discovered and network activity and stress monitored

through a graphical interface.

Transcend Network Supervisor features:

■ Web Management Support — You can monitor

and manage the management module through

the Switch 4007 Web Management suite of

applications.

■ Network Discovery — A Discovery wizard finds

up to 500 IP devices on the network. The discovery

works on the local subnet, the whole network or

across specified subnets. Transcend Network

Supervisor recognizes different types of device and

polls them for information.

■ Transcend^®Network Control Services

Support — You can also monitor and manage the

management module through the 3Com^®

Transcend Network Control Services.

■ Network Map — Discovered devices are

automatically mapped using graphics and color to

show links and network topology.

Switch 4007 Setup Wizard

■ Device Stress Monitor — Key network devices

are detected and monitored. The user can add and

tune monitors. Color stress bars show detailed

stress monitoring.

The Switch 4007 Setup Wizard, supplied on the

Software CD-ROM, is an easy-to-use Windows-based

application that helps you set up the Switch 4007 for

the first time.

Your directories may be different if you did not select

the default C:\3Com directory during installation.

Web Management and Netscape Navigator

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:

If you encounter problems accessing Help files from

Filter Builder or from other Web Management

applications when you use Netscape Navigator, clear

the browser memory cache and disk cache and restart

the browser.

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.

To clear the cache in Netscape Navigator:

1 In the browser window, from the Edit menu, select

Preferences

2 In the Category menu tree, select Advanced and

then, in the Advanced folder, select

MAINTAINING THE SWITCH 4007

This chapter describes the routine maintenance to

perform to keep your Switch 4007 chassis working at

its best. This chapter also provides instructions for

replacing power supplies and fan trays.

Routine Maintenance

On a regular basis, inspect your Switch 4007 chassis

to verify that all blank faceplates are securely attached

to the chassis, and the fans are running.

WARNING: Only trained electrical service personnel

should perform switch connections and

disconnections.

CAUTION: The Switch 4007 sends a fan fault

message when one fan fails in the fan tray. However,

the switch can continue to run if one fan fails in the

fan tray. If a second or third fan fails, in that fan tray,

no trap message is generated. Replace the fan tray

within 48 hours of receiving the trap message or

contact your service representative.

WARNING: Hazardous energy levels exist inside of

the chassis. Do not place hands or objects into the

switch or touch components on an inserted module.

There are no user-serviceable parts on either the

load-sharing power supplies or on the fan trays. If

these components fail, remove them as described in

this chapter and return them to your supplier. Keep

replacement power supply units and fan trays at your

site so that they are available if needed.

■ Ventilation to the switch is unobstructed.

■ All modules are securely seated in the backplane

and firmly attached to the chassis.

■ Module LEDs are functioning normally and show

normal readings.

This chapter provides information about the

Switch 4007 chassis and contains the following

topics:

■ Power requirements for all installed modules are

met by the power supplies.

■ Power cords from each power supply are not

■ Routine Maintenance

frayed or damaged.

■ Removing and Replacing a Power Supply

■ Removing and Replacing a Fan Tray

CHAPTER 6: MAINTAINING THE SWITCH 4007

WARNING: Hazardous energy exists within the

Switch 4007 system. Use extreme caution when you

install, remove, or replace the EME or a memory card.

■ Before you push the module into the chassis, make

sure that the module ejector handles are open.

■ When you slide the module into place, match the

left and right module guides.

When the system is on, never insert metal objects

such as a screwdriver or a finger with jewelry into

open module slots.

Unpacking Procedure

Use the following procedure when you unpack the 16

MB expansion memory card:

When the system is on, do not touch any connections

within the chassis w1ith your hands or fingers. Do not

insert metal objects into the backplane.

1 Verify that the expansion memory card is the correct

model by matching the model number that is listed

on the shipping box (Model Number 3CB9UD16) to

the model number that you ordered.

ESD Safety Information

Electrostatic discharge (ESD) can damage components

of the system. ESD, which occurs when the EME or a

memory card is improperly handled, can cause

complete or intermittent failures.

2 Remove the expansion memory card, in its antistatic

bag, from the shipping box.

3 Ensure that the box also contains the 16 MB

CAUTION: To prevent ESD-related damage:

■ Use proper grounding techniques.

All shipping boxes are reusable. After you remove the

contents, replace the packing materials and store the

shipping box for future use.

■ Keep the memory card in its antistatic bag until

you are ready to inspect or install it.

4 Remove the expansion memory card from the

antistatic bag and inspect it for damage. If the

expansion memory card appears to be damaged,

replace it in the antistatic bag, place it back in the

shipping box, and contact your local supplier.

Handling Precautions

When you handle the EME, follow these precautions:

■ Always handle the EME by the front panel only.

■ Do not touch the components, pins, leads, or

solder connections.

INTELLIGENT POWER SUBSYSTEM

The Switch 4007 provides a fault-tolerant, intelligent

power supply subsystem. The Switch 4007 chassis

To support redundancy, install one or more power

(n + 1 redundancy).

Power Availability and Power Supply Capacity

This section explains the following concepts

concerning power supply management:

components and resources continue to

operate, even under extreme failure

conditions.

■ 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.

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.

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.

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).

Download from Www.Somanuals.com. All Manuals Search And Download.

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.

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

Power Supply Modes

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.

The Switch 4007 runs in either of two power supply

modes:

■ Fault-Tolerant Mode

■ Non-Fault Tolerant Mode

If a power supply fails while the switch is running in

power fault-tolerant mode:

For optimal power redundancy in either power mode,

run the Switch 4007 with two power supplies.

■ EMEs respond by automatically disabling power

Fault-Tolerant Mode

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.

■ 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).

■ All modules that had power before the power

supply failure continue to receive power without

interruption.

While the chassis is running in fault-tolerant mode:

■ All installed power supplies are functioning and

contributing power to the chassis and modules.

■ Upon power supply recovery, the EME

automatically reenables power fault-tolerant

mode.

No single power supply is a dedicated standby

power supply.

APPENDIX B: INTELLIGENT POWER SUBSYSTEM

Operate the Switch 4007 in power fault-tolerant

mode to ensure that power that is equivalent to at

least one power supply is available to replace power

that is lost if a single power supply fails.

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.

To set the Switch 4007 to power fault-tolerant mode

or to power non-fault-tolerant mode, enter the set

power modecommand at the EME prompt.

If a power supply fails while the chassis is running in

power non-fault-tolerant mode:

■ Installed management modules may shut down

selected Switch 4007 interface modules and

switch fabric modules in an attempt to bring

installed module power consumption under the

now-reduced power budget.

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.

■ Installed interface modules and switch fabric

modules continue to operate without interruption

if the output of remaining installed power supplies

is sufficient to provide adequate power to all

installed modules.

■ If there is sufficient unallocated power budget, the

Switch 4007 sets to power fault-tolerant mode.

■ 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.

Non-Fault Tolerant Mode

A user-selectable mode in which 100 percent of the

power that can be allocated to all modules is available

to them (no power is held in reserve). This is the

default mode for power supplies as shipped.
