Before you attempt to mount the chassis in a rack:
Although the data communication LEDs that are used
in this product meet the regulatory requirements for
casual exposure to the eye, as with any source of
bright light, 3Com recommends that you do not look
into the light source.
■ Select a rack that can support at least 115.65 kg
(255 lb), which is three times the weight of a fully
loaded Switch 4007 chassis, and that provides
sufficient vertical space for each chassis that you
want to install.
LED Safety Information: IEC 825, Class 1 LED
Device. For connection only to Class 1 LED Devices.
■ Make certain that the rack that you use is properly
aligned and is squared. Use a framing square to
ensure that the rack is squared.
■ To maintain proper cooling in the chassis and to
maintain safety compliance, make certain that
blank faceplates cover any empty slots.

MANAGEMENT TOOLS
5
The Switch 4007 supports a range of network
management methods and contains an embedded
Web-based management agent.
The EME management module provides the following
management and control capabilities:
■ 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

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

provides a log of network activity. Unnecessary
events are automatically filtered out. Events can be
filtered and annotated, grouped, and sorted.
The Setup Wizard enables you to configure:
■ Serial communication settings
■ Network Alerts — Alerts can be attached to any
network event. The alerts can be by e-mail, audio
or visual pop ups or can start applications.
■ IP address, subnet mask, and default gateway for
the EME management module
■ Administrators who have management access
■ SNMP community strings
■ Reports — Generate reports on Network
Inventory, Capacity Planning, and Network
Topology.

MAINTAINING THE SWITCH 4007
6
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
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.

Removing a 930-watt Power Supply
Removing and Replacing a Power Supply
The Switch 4007 chassis can accommodate up to two
930-watt modular load-sharing power supplies.
This section describes how to remove and then
replace the 930-watt AC power supply
(Model Number 3CB9EP9) in the Switch 4007 chassis.
To remove a 930-watt power supply from a
Switch 4007 chassis:
CAUTION: When you replace a power supply, leave a
sufficient number of power supplies running at all
times to satisfy the power requirements of installed
modules. If you have an installed Enterprise
Management Engine (EME), enter the show power
budgetcommand to display current power conditions
for the Switch 4007. If you determine that removal of
a defective, but still functioning, power supply will
not cause a power deficit in the Switch, you can
remove the faulty power supply without losing power
to any modules.
1 Set the power supply’s Standby/On switch (Figure 22),
which is located on the front of the power supply, to
the Standby position.

To support redundancy, install one or more power

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:
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).

Power Management
69
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:

■ 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

interruption.

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.

that any product that is stated to meet this standard does not perform properly with
