Fan Modules
The Cisco MDS 9513 Director has a front panel fan tray with 15 fans with an abrupt stop-to-fan rotation
safety feature after power is disconnected or the fan tray is removed from the midplane. The Cisco MDS
9509 Director has a front panel fan module with nine fans and the Cisco MDS 9506 Director has a front
panel fan module with six fans.
Sensors on the supervisor module monitor the internal air temperature. If the air temperature exceeds a
preset lower-level threshold, the environmental monitor displays warning messages. If the air
temperatures exceeds a preset higher-level threshold, the switch will shut down.
If one or more fans within the module fail, the Fan Status LED turns red and the module must be
replaced. If the higher-level temperature threshold is not exceeded, the switch continues to run for five
minutes after the fan module is removed. This allows you to swap out a fan module without having to
bring the system down. For information on how to replace a fan module, see the
Installing Fan Modules" section on page
The fan module has one status LED that indicates the following conditions:
•
•
•
Caution The Cisco MDS 9000 Family switches have internal temperature sensors that are capable of shutting
down the system if the temperature at different points within the chassis exceed certain safety thresholds.
To be effective, the temperature sensors require the presence of airflow; therefore, in the event a fan
module is removed from the chassis, the Cisco MDS 9000 Family switches will be shut down after five
minutes to prevent potentially undetectable overheating. However, the switches will shut down sooner if
the higher-level temperature threshold is exceeded.
The Cisco MDS 9513 Director also has crossbar module fan trays located at the back of the chassis.
There is one fan per crossbar module. There is one LED that provides operational status.

Supervisor Modules
The Cisco MDS 9500 Series supports two types of supervisor modules: Supervisor-1 and Supervisor-2
modules. Both the supervisor modules provide the control and management functions for the Cisco MDS
9500 Series. The Cisco MDS 9500 Series supports two supervisor modules for redundancy. In the event
of an internal component failure, the standby supervisor module takes over, if installed. This section
discusses the following modules:
•
•
The internal bootflash installed on the modules are not field-replaceable units. Do not remove or replace
Note
internal bootflash on the modules. Modifying the factory installed bootflash is not supported.
