A SCSI backplane comes pre-installed in the TS300-E3 PS4 model. The SCSI

backplane has four 68-pin SCSI connectors to support SCA SCSI hard disks.

The backplane design incorporates a hot swap feature to allow easy

connection or removal of SCSI hard disks. The LEDs on the backplane

connect to the front panel LEDs to indicate HDD access, HDD failure,

thermal failure, or fan failure. See section “1.6 LED information.”
