IIRC, the chassis locator LEDs are driven from the mobo option, not from
the SAS backplane. It wouldn't surprise me if the locator was not wired, or
wired to an internal LED, depending on the exact model.

NB, Supermicro gear is very flexible and many options can be [re]wired by hand
and thus can be inconsistently configured in the field. It is a good habit to
verify disk serial numbers to slot maps as you install disks.
