Use only the filler panels provided with the Pilot to maintain proper airflow
and EMI conformance for empty slots inside the Pilot.

Fail over the Pilot before replacing the component using Guided
Maintenance
Each Pilot supports a single 6 Gb/s SAS HBA on the PCIe slot of its riser. The SAS
HBA is installed in the internal PCIe 4 slot of riser 3 and is not visible from the
back of the Pilot. To service a SAS HBA, the PCIe risers inside the Pilot and the
filler panels inside the riser must be removed. The SAS HBA is a customer
replaceable unit (CRU) and is not hot-serviceable. However, replacing a SAS
HBA will require failing over all operations to the other Pilot. The following
figure shows the location of the SAS HBA inside a riser board assembly.

Note: The SAS HBA can be accessed only after removing the cover over the Pilot
chassis.
Note: To replace a SAS HBA, you do not need to remove the Pilot from the rack
but extend it along the Pilot rails using the cable management arm (CMA).
Note: The riser that contains the failed SAS HBA must be removed before
servicing the HBA.
