NOTICE:
The fan modules are hot-pluggable. Remove and replace only one fan
module at a time in a system that is turned on. Operating the system without all six
fan modules for extended periods of time can cause the system to overheat.
1 Locate the faulty fan.
Each fan module has indicators that identify a faulty fan. See Figure 1-12.
2 Remove the fan module. See "Removing a Fan Module" on page 161.
3 Examine the blades for debris. If debris is present, carefully remove it.
4 Reseat the faulty fan. See "Installing a Fan Module" on page 162.
5 If none of the fans show a fault LED and the blades will not power on,
check the LCD display or CMC for status messages.
6 If the problem is not resolved, install a new fan.
7 If the new fan does not operate, see "Getting Help" on page 217.

NOTE:
To eliminate the possibility of a hardware problem with the module or its
attaching devices, first ensure that the module is properly initialized and
configured. See the Configuration Guide and the documentation that came with the
module before performing the following procedure.
1 Verify that the latest firmware is installed on the CMC module.
See support.dell.com for the latest firmware and refer to the release notes
for firmware compatibility and update information.
2 Verify that the CMC(s) have valid IP addresses for the subnet. Verify using
the ICMP ping command.
