5.5Dismounting HDDs

Since the method and procedure for dismounting the HDD for replacement of 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 15 seconds for the spindle motor to stop completely.

2)Then, dismount the HDD using the HDD 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 unitil the spindle motor stops (about 15 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 bag (refer to Section 5.1 and 6.5).
