    This OID will return the chassis status
    systemStateChassisStatus
    1.3.6.1.4.1.674.10892.1.200.10.1.4; it is mapped as :

    1:OTHER

    2:UNKNOWN

    3:OK

    4:NONCRITICAL

    5:CRITICAL

    6:NONRECOVERABLE

     Advantage is that it will change status each time the hadware status
    of any component will change. For example if a disk or power supply fails
    it will change status.
