■Slots for two Enterprise Management Engine
(EME) management modules that do not take up
interface module or switch fabric module space.
Switch 4007 starter kits are supplied with with one
management module (Model Number: 3CB9EME)
installed in the lower slot. You can install a second
management module to provide standby
management support.
The management module uses the management
bus to send commands to all installed interface
modules and the switch fabric module and to
collect information from the modules.
■A single passive backplane that enables the use of
multiple networking technologies, defined by the
type of switch fabric module that is installed.
■One slot for a switch fabric module in the chassis
to provide optimal network performance.
■Gigabit Ethernet starter kits (Model Numbers
3C16810 and 3C16811) have one 24-port
Switching Fabric (Model Number: 3CB9FG24T)
preinstalled in slot 7.
■Fast Ethernet starter kits (Model Numbers
3C16815 and 3C16816) have one 9-port
Switching Fabric (Model Number: 3CB9FG9)
preinstalled in slot 7.
■Slots for two power supplies to supply 930 watts
with n + 1 redundancy and 1860 watts without
n + 1 redundancy, depending on the type and
quantity of installed modules.
Switch 4007 starter kits have one 930W AC Power
Supply (Model Number: 3CB9EP9) preinstalled in
the lower bay.
■Power supplies that you can add or replace while
the chassis is running (referred to as warm
swapping).
■Slots for six interface modules. In Switch 4007
starter kits, modules are preinstalled in slots 1 and
2, and the remaining slots are empty.
■Packet switching at an aggregated bandwidth of
up to 30 Gbps.
■Power fault-tolerant mode where you can reserve
the power of a single power supply (930 watts) to
act as a backup if the other power supply fails.
■One exhaust fan tray (with the power and
reliability of four fans) to make sure that the
chassis maintains the optimal temperature for
operation.

■Modules

16 CHAPTER 1: ABOUT THE SWITCH 4007
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.
Figure 3 930-watt AC Power Supply in the Switch 4007
You can add or replace power supplies while the
chassis is running (referred to as warm swapping). See
Chapter 6, “Maintaining the Switch 4007”, for
instructions about how to replace a faulty power
supply.
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.
Figure 4 shows the 930-watt AC power supply for the
Switch 4007 chassis.

Hardware Components 17
Fan Tray
The Switch 4007 chassis contains one fan tray, which
contains four fans (Model Number 3CBEF7). The fans
cool the interface modules, the switch fabric module,
and the management modules.
Figure 5 Switch 4007 Chassis Fan Tray
Module Slots in the Switch 4007 Chassis
You insert modules horizontally into the chassis. Slots
are numbered from bottom to top, with the bottom
slot being number 1.
The chassis contains:
■Management slots — There are two slots (slot 8
and slot 9) for management modules:
■The Enterprise Management Engine (EME) is an
SNMP-based network management module
that manages and controls the Switch 4007 and
its modules. The management module is the
primary communication mechanism into the
switch and modules. You manage other
intelligent modules within the chassis through
the management module.
■The Enterprise Management Controller (EMC)
module provides standby controller functions
for an EME in a Switch 4007.
■Payload slots — There are six slots (slot 1 through
slot 6) for interface modules. The interface
modules offer a selection of packet-based or
cell-based interfaces that work with the switch
fabric module.
■Switch fabric slots — There is one slot (slot 7) for
a Gigabit Ethernet Switch Fabric Module, which is
the central backplane aggregator for the Switch.
To learn more about management, switch fabric, and
Fast Ethernet and Gigabit Ethernet interface modules,
see Chapter 2, “Switch 4007 Modules”.

18 CHAPTER 1: ABOUT THE SWITCH 4007

2SWITCH 4007 MODULES
This chapter contains the following topics:
■Overview
■Switch Fabric Modules
■Management Modules
■Fast Ethernet Modules
■Gigabit Ethernet Modules
■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
