InfiniBand Fabric Initialization and Management
Subnet Management and Subnet Administration are standard components defined by the
InfiniBand Specification which implement fabric initialization, discovery, and configura-
tion.
The chassis is basically an InfiniBand fabric built out of individual InfiniBand switch
devices and appears so to external Subnet Managers. The chassis supports the System
Image GUID feature of the InfiniBand specification which means that software manage-
ment tools that support this feature can recognize all the internal devices as a single switch
system.

The switch's switching fabric can be managed by MLNX-OS, as well as any third
party Subnet Management software running on an InfiniBand Host that is connected to
any switch port. The switch is also compatible with the Open Source Subnet Manager
OpenSM.
On SX65xx systems, when having dual management systems, first connect the cable
and configure the master management module CPU and only then configure the slave.
By default the master CPU is the top management module. For further information on
the master and slave roles, see the MLNX-OS Software UM section "High Availabil-
ity" for more information.
Initial configuration must be done on all of the management modules.
Connect the host PC RS232 connector to the CONSOLE port of the manage-
ment module using the supplied cable.
