6.2.2Maintenance requirements

CAUTION

1.Always ground yourself with a wrist strap connected to ground before handling. ESD (Electrostatics Discharge) may cause the damage to the device.

2.To prevent electrical damage to the disk drive, turn the power off before connecting or disconnecting a cable, connector, or plug.

3.Do not remove a PCA.

4.Do not use a conductive cleaner to clean a disk drive assembly.

5.Ribbon cables are marked with a colored line. Connect the ribbon cable to a cable connector with the colored wire connected to pin 1.

6.2.2Maintenance requirements

(1)Preventive maintenance

Preventive maintenance such as replacing air filters is not required.

CAUTION

Damage

Never open the disk enclosure in the field.

Opening the disk enclosure may cause an irreparable fault.

(2)Service life

See "(3) Service life," in Section 2.1.5.
