The HSBP does not route HDD activity signal to the front panel, and is not subject to the LED
being continuously on when running SAS HDDs. Any HDD activity (bus activity) driven from
SATA/SAS host on baseboard or HBA card hosts that cable HDD activity to baseboard 2pin
header would still result in the FP LED blinking. The following table shows the HDD activity LED
differences between with SATA and SAS HDDs.
