  • Page 71: Figure 55 Removal Of A System Fan

    An important feature of the storage enclosure design is redundancy. The storage enclosure can maintain continuous operation during the replacement of a single system fan module, as long as it is within the time limit of two (2) minutes, since removal of a system fan module significantly reduces airflow in the main bay. CAUTION If you remove any FRU while the storage enclosure is powered up, you must replace it with a known good spare within the allotted time for that FRU.
