Fujitsu MAG3182FC, MAG3091FC, MAF3364FC Maintenance Information 6.2.1 Maintenance requirements

(1)Interface test

The operations of the loop and data buffer on the IDD are checked with the WRITE BUFFER and READ BUFFER commands.

(2)Basic operation test

The basic operations of the IDD are checked by executing self-diagnosis with the SEND DIAGNOSTIC command (see Subsection 6.1.1).

(3)Random/sequential read test

The positioning (seek) operation and read operation are tested in random access and sequential access modes with the READ, READ EXTENDED, or VERIFY command.

(4)Write/read test

By using a data block in the internal test space, the write/read test can be executed with an arbitrary pattern for a disk drive in which user data is stored.

6.2Maintenance Information

6.2.1Maintenance requirements

(1)Preventive maintenance

Preventive maintenance such as replacing air filters is not required.

CAUTION

Damage

Do not open the DE in the field because it is completely sealed.

(2)Service life

The service life under suitable conditions and treatment is as follows. The service life is depending on the environment temperature. Therefore, the user must design the system cabinet so that the average DE surface temperature is as possible as low.

∙DE surface temperature:

∙DE surface temperature:

∙DE surface temperature:

∙DE surface temperature:

45°C or less 46°C to 50°C 51°C to 55°C 56°C and more

5years

4 years

3 years

Strengthen cooling power so that DE surface

temperature is 55°C or less.

Even if the IDD is used intermittently, the longest service life is 5 years.
