Maintenance
1. Don’t install or remove a PCA or connect or disconnect
a cable or connector plug when the drive is powered.
This may give you an electric shock.
2. Keep away from mechanical assemblies in the unit
during operation. This may cause injuries.
3. Avoid dangerous detergent when the disk drive is
cleaned.
1. Before touching a PCA or the drive, wear a wrist strap
and perform the human body grounding to discharge
static electricity from your body. This will prevent
irreparable damage to the PCA and the head of the drive.
2. Don’t install or remove a PCA or connect or disconnect
a cable or connector plug when the drive is powered.
This will prevent electrical damage to the disk drive.
3. Operating the disk drive with one or more PCA missing
will be unpredictable. Only power the drive with all
boards installed.
4. Avoid any detergent which may cause short circuits
when cleaning assemblies.
5. Keep all vents open opened and unblocked. Avoid other
conditions which may cause circuits to overheat.
6. A ribbon type cable has one line marked. Ensure that
this line is always connected to pin 1 of the cable
connector.
