Caution - If you remove one of the fans in the rear row (fans 3, 4, or 5), 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.
This procedure can be performed by customers while the server is running. See Hot Service, Replaceable by Customer for more information about hot service procedures.
The Service Action Required LEDs are located on the fan module as shown in Locate a Faulty Fan Module.
Caution - When removing a fan module, do not rock it back and forth. Rocking fan modules can cause damage to the fan board connectors.
Caution - When changing fan modules, note that only the fan modules can be removed or replaced. Do not service any other components in the fan compartment unless the system is shut down and the power cords are removed.
