Fan guidelines
The server has 4 fan modules with 2 rotors in each module. The fan modules operate in a 7+1
configuration.
Observe the following guidelines:
• If one rotor fails, the system runs with the fans in a degraded condition.
• If a second rotor fails, either in the same fan module or a different one, the system performs an OS
type shutdown if the health OS agents are loaded. The chance of two rotors in the same module
failing is low.
• If a fan module is missing, a message appears indicating that cooling is not adequate. Then, the
system starts to shut down.
• If you remove a hot-plug fan module, you have approximately 60 seconds to replace the module.
Otherwise, the system starts to shut down.
