Remove a Fan Module
This is a hot-service procedure that can be performed by a customer while the server is running.
Caution - While the fan modules provide some cooling redundancy, if a fan module fails,
replace it as soon as possible to maintain server availability. When you remove one of the fan
modules, you must replace it within 30 seconds to prevent overheating of the server.
