Question I have a CSE-M35T1 mobile rack and discovered that the HD LED never blinks (which is not the case with another CSE-M35S). Answer The CSE-M35S is a SCSI mobile rack where the drive activity signal is associated with the data signal; whereas the CSE-M35T1 is a SATA mobile rack in which the drive activity signal requires a separate cable. Therefore, you should connect the JP26 jumpers on the CSE-M35T1 to your SATA controller to get the LEDs to blink. Was this FAQ helpful?
