11.1 Configuration of the Fan Units
This section describes the configuration and the locations of the fan units.
Five fan units are mounted in each chassis. Each fan unit has two cooling fans that
cool the components in the chassis.
If a fault occurs with a cooling fan during system operation, the XSCF detects the
error. However, the system can continue operating because the fans have a
redundant configuration.
