The ATM switch fabric module is the core cell
switching engine of the CoreBuilder 9000 ATM
Enterprise Switch, controlling and monitoring
passive backplane and ATM activity.
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.
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.

Switch Fabric Modules

Switch fabric modules fit into the CoreBuilder 9000
chassis. The scalable design of the CoreBuilder 9000
platform provides the Switch with the highest
bandwidths.
You can select the switch fabric module based on
technology:
Gigabit Ethernet, packet-based interface —
This high-performance, packet switch fabric
module has an initial aggregate switching capacity
of 48 Gbps.
ATM, cell-based interface — The ATM Switch
Fabric Module has an initial aggregate switching
capacity of 30 Gbps.

The CoreBuilder 9000 7-slot chassis contains one slot
(slot 7) for a switch fabric module. The 7-slot chassis
is shipped with slot 7 open and not covered by a
blank faceplate.
The CoreBuilder 9000 8-slot chassis contains two
slots (slot 7 and slot 8) for switch fabric modules. The
8-slot chassis is shipped with slot 7 open and not
covered by a blank faceplate; slot 8 is covered with a
blank faceplate. You usually install the first switch
fabric module in slot 7.
The CoreBuilder 9000 16-slot chassis contains two
slots (slot 8 and slot 9) for switch fabric modules. The
16-slot chassis is shipped with slot 8 open and not
covered by a blank faceplate; slot 9 is covered with a
blank faceplate. You usually install the first switch
fabric module in slot 8.
