    ---Solution---

    The 18000 has a total of 9 fans. A picture with the top cover off an 18000 can be found in the web administration page under Monitor>>System Status. There are two rows of fans towards the front half of the unit. One row contains 5 fans and the other has 4 fans.


    Here is a layout of the fans.


    Rear

    Chassis Fan1A| |CPU_2 FanA| |CPU_1 FanA| |Chassis Fan2A| |Chassis Fan3A

    Chassis Fan1B| |CPU_2 FanB| |CPU_1 FanB| |Chassis Fan2B| |No fan

    Front

    If the fan fails to spin or spins slower than expected, the amber LED on the failed fan should be lit. Here is a sample of fan messages in the event of a fan failure. Note the intentional removal of a fan will trigger a failure message.
