Figure 55 Removal Of A System Fan - Seagate Exos CORVAULT Hardware Installation And Maintenance Manual

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. If you do not replace the FRU and, when applicable, close the related
cover within the identified time limit, you void the product warranty and the storage enclosure might overheat, causing
equipment failure and possible data loss.
CAUTION Do not remove covers from any FRU. There is a danger of electric shock inside. Return the FRU to your
supplier for repair.
To remove and replace a system fan module:
1. If you plan on removing all system fan modules, properly shut down the storage enclosure.
2. Retrieve the new system fan module in its static-protected container, ready to access and use it upon removal of the
faulty one.
3. Press down on the release latch to disengage the system fan module from the locked position.
4. Using the handle, gently remove the system fan module using a steady pressure to pull it from the storage enclosure
while supporting it with your other hand and set it aside.

5. While maintaining proper static protection, remove the new system fan module from its static-protected container.
6. Inspect the system fan module carefully to make sure it is not damaged or bent in any way, paying particular
attention to connector pins.
7. Properly orient the system fan module so you can grasp the handle, then orient it to its empty slot.
8. Slide the system fan module into its empty slot until you feel it connect to the power midplane.
