Remove a Fan Module

You do not have to power off the server to service fan modules.
Do not begin this procedure unless you have a replacement fan module and you are ready to
install it right away.
When removing and replacing a fan module in the Oracle Exadata Storage Server
Caution -
X7-2, complete the entire procedure within 60 seconds to maintain adequate cooling within the
system. Remove and replace only one fan module at a time. Ensure that you have obtained the
replacement fan module and that is it is ready for installation before starting the replacement
procedure. Each fan module contains two fans, with one fan motor per fan. The two fan motors
provide separate tachometer signals so that the fan module reports two tach signals to Oracle
ILOM. Even if only one fan motor is faulted within the fan module, the Oracle ILOM service
processor detects that two fan motors have failed to spin while the fan module is removed.
If you do not replace the fan module within 20 seconds of removal, Oracle ILOM takes the
protective action to shut down the system to prevent thermal damage to the system.
