Cisco MDS 9718 Director Crossbar Fabric Switching Modules

The Cisco MDS 9718 Director supports up to six crossbar fabric (xbar) switching modules. The crossbar
fabric switching modules, DS-X9718-FAB1 and DS-X9718-FAB3 are supported. The crossbar fabric switching
modules are installed vertically at the back of the chassis behind the fan modules.
Crossbar fabric switching modules slots 1 and 2 are behind the fan module slot 1, the crossbar fabric switching
modules slots 3 and 4 are behind the fan module slot 2, and crossbar fabric switching modules slots 5 and 6
are behind the fan module slot 3.
Cisco MDS 48-Port 32-Gbps Fiber Channel Switching Module needs a minimum of 6 (DS-X9718-FAB1)
Crossbar Fabric-1 Switching Modules to deliver full bandwidth to all the modules in the switch. Each
DS-X9718-FAB1 Crossbar Fabric-1 Switching Module provides 256-Gbps of fiber channel bandwidth per
slot.
Cisco MDS 48-Port 32-Gbps Fiber Channel Switching Module needs a minimum of 3 (DS-X9718-FAB3)
Crossbar Fabric-3 Switching Modules to deliver full bandwidth to all the modules in the switch. Each
DS-X9718-FAB3 Crossbar Fabric-3 Switching Module provides 512-Gbps of fiber channel bandwidth per
slot. A fourth crossbar fabric switching module is required for N+1 protection.
The DS-X9718-FAB1 Crossbar Fabric-1 Switching Modules are supported from Cisco MDS NX-OS Release
7.3(1) or later. DS-X9718-FAB1 modules are supported only with Supervisor-1E Modules (DS-X97-SF1E-K9).
The DS-X9718-FAB3 Crossbar Fabric-3 Switching Modules are supported from Cisco MDS NX-OS Release
8.4(2a) or later. DS-X9718-FAB3 modules are supported only with Supervisor-4 Module (DS-X97-SF4-K9).
Note You cannot have a mix of different supervisor modules or a mix of different crossbar fabric switching modules
in a chassis, except during migration of a supervisor module or a crossbar fabric switching module.
