1.Current limiter value for +5 VDC power: 5 A or less

2.Specifications under transporting condition are under the packaging specified by Fujitsu.

3.A voltage drop may occur depending on the used power supply or power cable.

4.If power for the terminators in the other SCSI devices is supplied via an optical disk drive, note that the current of the +5VDC power for the optical disk drive may increase by a maximum of 200 mA. The method of supplying power to terminators cannot be changed.

5.Table 2.4 lists power consumption in power save mode when the temperature inside the drive is 20°C or lower.

Standby mode

1.0W(typ)

 

 

 

 

6.If the temperature inside the drive is 14°C or lower, disk access might become longer because the speed of the related mechanisms varies with temperature.
