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 in the rear row (fan modules 3, 4, or 5), you must replace it within 30 seconds to
prevent overheating of the server.
