1Run the appropriate diagnostic test. See "Using Server Administrator Diagnostics" on page 153.

2Open the system. See "Opening and Closing the System" on page 66.

CAUTION: The cooling fans are hot-pluggable. To maintain proper cooling while the system is on, only replace one fan at a time.

3Locate the faulty fan indicated by the LCD display or diagnostic software. For the identification number of each fan, see Figure 3-8.

4Ensure that the faulty fan's power cable is firmly attached to the fan power connector. See "System Fans" on page 78.

NOTE: Wait 30 seconds for the system to recognize the fan and determine whether it is working properly.

5If the problem is not resolved, install a new fan. See "System Fans" on page 78.

If the replacement fan is working properly, close the system. See "Opening and Closing the System" on page 66.

If the replacement fan does not operate, see "Getting Help" on page 167.
