The activity LED connectors, designated JP26,
and JP27 are used to indicate the activity
status of each SAS drive. The activity LED
connector is located on the front panel. For
the activity LED connector to work properly,
connect using a 10-pin LED cable. This is only
used when the activity LED is not supported by
the hard drive.
