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.
