Servicing Fan Modules (CMIOU Chassis)

A CMIOU chassis contains eight fan modules. The server can operate at full capacity with
seven fan modules installed in the CMIOU chassis. The server will not operate with fewer than
seven fan modules. If the server is operating with seven fan modules and one or more of those
fan modules fails, the server will continue operating until defined temperature thresholds are
exceeded, at which point the server will perform a graceful shutdown.
