Replacing an Oracle ZFS Storage ZS9-2 Fan Module
Unpack the replacement fan module and get it ready to insert into the controller chassis as soon as the faulted fan is removed.
You do not have to power off the controller to service fan modules. You should not begin this procedure unless you have a replacement fan module and you are ready to install it immediately.
Caution:
When performing the actual removal and replacement of a fan module in the Oracle ZFS Storage ZS9-2 controller, you must 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 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 the fan module is not replaced within 60 seconds of removal, Oracle ILOM will take the protective action to shut down the system to prevent thermal damage.Fan modules are hot-swappable and can be removed and installed while the controller is running without affecting other hardware capabilities. Use the following procedure to replace an Oracle ZFS Storage ZS9-2 fan module.
