• Fan status indicator indicates a problem with the fan.
Action
CAUTION:
Only trained service technicians are authorized to remove the system cover and access any of the
components inside the system. Before performing any procedure, see your Product Information Guide for
complete information about safety precautions, working inside the computer and protecting against electrostatic
discharge.
1 Run the appropriate online diagnostic test. See "Using Dell PowerEdge Diagnostics" on page 117.
2 Open the system. See "Opening and Closing the System" on page 46.
CAUTION:
The cooling fans are hot-pluggable. To maintain proper cooling while the system is on, only replace
one fan at a time.
3 Locate the faulty fan indicated by the LCD panel, the diagnostic software, or the fan indicator that is
blinking amber. For the identification number of each fan, see Figure 3-4.
4 Ensure that the faulty fan's power cable is firmly attached to the fan power connector. For a hot-plug
fan, remove and reseat the fan. See "Cooling Fans" on page 48.
NOTE:
Wait 30 seconds for the system to recognize the fan and determine whether it is working properly.
5 If the problem is not resolved, install a new fan. See "Cooling Fans" on page 48.
If the replacement fan is working properly, close the system. See "Opening and Closing the System" on
page 46.
If the replacement fan does not operate, see "Getting Help" on page 129.
