         Perform these steps:

               Check the room ambient temperature to ensure that it is within the operating specifications for the chassis.
               Make sure that all fan/blower modules are running.  Replace fan modules if necessary.
               Make sure that a device or filler is installed in each bay in the front and rear of the chassis, and make sure that there is nothing covering the bays. Any missing components can cause a major reduction in airflow for the blade server.
               Make sure that there is nothing covering the media tray (that will disrupt the airflow to the ambient temperature sensor).
               Update the firmware for the advanced management module. You can find firmware on the IBM BladeCenter software and device drivers Web page.
               Update the firmware for the blade server.
               For all blade servers other than the JSxx blade servers, make sure the heat sink and CPU are secured on the system board.

                     Note: Be careful when handling the heat sink and CPU, they may be extremely hot.
