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,
