3 Chassis Management and
Fabric Modules
Chassis Management Module (CMM)
The Chassis Management Module (CMM) is the management unit for the OmniSwitch chassis. In its role
as the management unit, the CMM provides key system services, including:
•
Console, USB, and Ethernet management port connections to the switch
•
Software and configuration management, including the Command Line Interface (CLI)
•
Web-based management (WebView) management
•
Power distribution
•
Switch diagnostics
•
Important availability features, including redundancy (when used in conjunction with another CMM),
software rollback, temperature management, and power management
Chassis Fabric Module (CFM)
The Chassis Fabric Module (CFM) provides expanded switching fabric for the chassis. Data passing from
one NI module to another passes through the CFM. Additional CFMs provide increased switching
throughput, as well as redundancy.
CMM and CFM Slot Locations
Slot numbers are clearly marked on the OS10K front panel. In a non-redundant (i.e., single CMM)
configuration, the CMM module can be installed in either slot A or slot B of the chassis. For redundant
CMM configurations, a CMM module must be installed in both slot A and slot B.
Refer to the diagram on
page 3-9
for more information on slot locations. Refer to
page 3-9
for more
information on CMM redundancy.
CFM modules can be installed in slots C and D. If redundant (dual) CMMs are installed, two CFMs must
be installed in order to provide redundancy.
