San192C-6 Crossbar Fabric Modules - IBM SAN192C-6 Installation, Service And User Manual

When a fabric module needs to be located, the locator LED of the corresponding fan module must be
activated, followed by the locator LED of the crossbar fabric switching module, using the CLIs locator-
led fan <fan module number> and locator-led xbar <xbar slot number>. For example,
to locate the crossbar fabric switching module in slot 4, the locator LED of the fan module 2 needs to be
activated followed by the locator LED of the crossbar fabric switching module 4.

SAN192C-6 Crossbar Fabric Modules

The SAN192C-6 supports up to six crossbar (xbar) fabric switching modules. The crossbar fabric
switching modules Crossbar Fabric-1 and Crossbar Fabric-3 are supported. The crossbar fabric switching
modules are installed vertically at the back of the chassis behind the fan modules. Crossbar fabric
switching module slots 1 and 2 are behind the fan module slot 1, crossbar fabric switching module slots 3
and 4 are behind the fan module slot 2, and crossbar fabric switching module slots 5 and 6 are behind the
fan module slot 3.
The IBM c-type SAN 48-Port 32-Gbps Fiber Channel Switching Module with Crossbar Fabric-1, needs a
minimum of 6 crossbar fabric switching modules to deliver full bandwidth to all the modules in the switch.
Each Crossbar Fabric-1 Switching Module provides 256-Gbps of fiber channel bandwidth.
The IBM c-type SAN 48-Port 32-Gbps Fiber Channel Switching Module with Crossbar Fabric-3, needs
a minimum of 3 crossbar fabric switching modules to deliver full bandwidth to all the modules in the
switch. Each Crossbar Fabric-3 Switching Module provides 512-Gbps of fiber channel bandwidth. A fourth
crossbar fabric switching module is required for N+1 protection.
The Crossbar Fabric-1 switching module is supported from NX-OS Release 6.2(1) or later. It is supported
only with Supervisor-1 Module.
The Crossbar Fabric-3 switching module is supported from NX-OS Release 8.4(1) or later. It is supported
only with Supervisor-4 Module.
