Installation (4) Port control parameters The following parameters are used to control the ready LED signal behavior. Parameter • READY LED MEANING Default value 0 (LED is on when HDD is ready) 5.5 Dismounting HDDs Since the method and procedure for dismounting the HDD, etc. depends on the locker structure of the system, etc., the work procedure must be determined in consideration of the requirements specific to the system. This section describes the general procedure and notes on dismounting the HDD. High temperature To prevent injury, never touch the HDD while it is hot. The DE and LSI become hot during operation and remain hot immediately after turning off the power. Damage 1. When dismounting the HDD which is mounted on the system while power is supplied to it. 1) Stop the spindle motor by a START/STOP_UNIT command. It takes about 30 seconds for the spindle motor to stop completely. 2) Then, dismount the HDD using the drive mounting/dismounting mechanism, etc. of the system. When removing the HDD, avoid exposing it to shock or vibration. Just in case, stop dismounting once when SAS connector breaks off contact and wait until the spindle motor stops (about 30 seconds.). 2. When dismounting the HDD which is mounted on the system while power is not supplied to it. • Dismount the HDD using the HDD mounting/dismounting mechanism, etc. of the system. When removing the HDD, avoid exposing it to shock or vibration. 3. When storing or transporting the HDD, put it in the antistatic case (Fcell) (refer to Section 5.1 and 6.5). 64 C141-E252
