Remove a Fan Module
 | 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 fans in the rear row (fans 3, 4, or 5), you must replace it within 30 seconds to prevent overheating of the server. |
 | Caution - The fan module contains hazardous moving parts. Unless the power to the server is completely shut down, replacing the fan modules is the only service permitted in the fan compartment. |
A customer can perform this procedure while the server is running. See Component Service Categories for more information about hot-service procedures.
