2 Hardware Issues
This section describes important operating notes and known hardware issues for Oracle Server X9-2L.
Failure of a Single Server Fan Module Might Impact Performance
Important Operating Note
If a single server fan module fails and the server's operating temperature rises above 30 degrees C (86 degrees F), the performance of the server's processors might be reduced.
Remove and Replace a Fan Module Within 60 Seconds
Important Operating Note
When removing and replacing a server fan module, you must complete the entire removal and replacement procedure within 60 seconds in order to maintain adequate cooling within the system. In anticipation of this time limit, prior to starting the replacement procedure, obtain the replacement fan module and verify that the new fan module is ready for installation. Remove and replace only one fan module at a time.
Fan modules are hot-swappable components, with N+1 fan redundancy. 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 tachometer 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 to the system. This is expected behavior.
