Prepare the Server for Warm Service (Oracle ILOM Web Interface)
This procedure describes how to prepare the server for warm service. Use warm service to remove and replace CMOD, DIMM, and processor components without accessing the server back panel to disconnect AC power cords or shutting down Oracle ILOM.
When Oracle ILOM detects that two fan modules in a single cooling zone (a vertical column) have been removed, the SP removes power from the CMODs, allowing you to service CMODs and their subcomponents without removing the power cords. Oracle ILOM remains available in warm service mode.
For more information about component serviceability, see Component Serviceability Requirements.
Caution:
Loss of service or component damage. Do not replace any components except for CMODs and internal CMOD subcomponents while the server is in warm service mode.
Caution:
Data Loss. Do not remove more than one fan module from a column while the system is in Main power mode. This action removes power from the CMODs and causes an immediate shutdown. On an eight-CMOD system, this applies to all fan modules. On a four-CMOD system, this applies to the fan modules in the left-hand fan frame.
This procedure is performed locally and requires physical access to the server front panel.
