Caching Services Module
The Caching Services Module (CSM) provides virtualization services that allow the Cisco MDS 9000
Family switches to reallocate physical resources as virtual resources for increased efficiency. The CSM
receives and sends data through the switch backplane. It has two disk drives, two internal batteries for
backup in case of power failure, and no external ports.
CSMs must be implemented in pairs in the fabric to provide redundancy and backup. Only two or more
CSMs in a fabric are supported. However, the CSMs need not to be installed in the same switch.

Description
All diagnostics pass and the module is operational (normal
initialization sequence).
One of the following occurs or occurred:
The module is booting or running diagnostics (normal
•
initialization sequence).
•
The inlet air temperature of the system exceeded the
maximum system operating temperature limit (a minor
environmental warning). To ensure maximum product life,
you should immediately correct the environmental
temperature and restore the system to normal operation.
One of the following occurs or occurred:
The diagnostic test failed. The module is not operational
•
because a fault occurred during the initialization sequence.
he inlet air temperature of the system exceeded the safe
•
T
operating temperature limits of the card (a major
environmental warning). The card shut down to prevent
permanent damage.
