19.1 Configuration of the Fan Units
This section describes the configuration and the locations of the fan units.
Four fan units are mounted in each chassis.
If one of the cooling fans fails during system operation, the XSCF detects the error.
However, the system can continue operating because the fans have a redundant
configuration.
