4 = SCA ports (hard disk carriers)

Each hard disk carrier is assigned to two drive indicators. The upper indicator (green) shows the drive activity. The lower indicator (orange) shows a hard disk error. However, a hard disk error can only be indicated when the drive is operated on a disk array controller.

The SCSI bus is terminated and the hot-replace control realized on the platter.
