Replacing a system fan

The system fans on the server can be individually replaced or hot- swapped in the event of failure. To provide adequate cooling in the chassis, at least 3 fans must be installed to the server. Each fan is equipped with an LED to indicate a fan failure condition. If the system fan LED is on, the fan assembly needs to be replaced. The system fan LED remains off during normal operation.

The system ships out with only three system fans installed. The server allows for installation of 3 more additional system fans in the event of a fan failure.

System fans must be installed in the following order:

First - Fan 2, fan 4, and fan 5

Second - Fan 1, fan 3, and fan 6

Warning! To ensure proper system cooling, the replacement of a failed system fan should be completed within one minute.

To replace the system fan

Caution! Hot-swap operations should be performed only if a failure occurs in the system fan assembly.
