1.1.1 Rules for maintenance

The following cautions must be observed to prevent injury during troubleshooting

or maintenance.

Static, Damage

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.

The following cautions must be observed to avoid damaging the disk drive during

troubleshooting and maintenance.

Device damage

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. Do not apply excessive force to the cover under any

circumstances. Doing so may cause irreparable damage to the

cover.
