7.HANDLING OF ADDITIONAL DISK ENCLOSURE

This chapter describes how to handle the additional disk enclosure.

7.1Notes on Handling of Additional Disk Enclosure

Note the following in use of the additional disk enclosure. Invalid handling of the additional disk enclosure may cause it to be defected and/or some data to be broken.

If the HDD READY LED (green) blinks, the disk access operation is indicated on the host system, or the initialization is being operated, do not turn on/off the powers of the additional disk enclosure. Do not reset the host system.

If the HDD READY LED (green) is lit or blinks and the disk access operation is indicated on the host system, do not give vibrations and shocks to the additional disk enclosure.

Because the additional disk enclosure is a precision device, it shall not be subject to hard vibration or shock.

The features of the additional disk enclosure are effective only for the hardware failure (e.g., the hard disk is physically damaged or inoperative). The software failure (e.g., the data is lost or rewritten due to program excursion) is not covered by these features. When the software failure would occur, the system could seriously be damaged. To minimize the damage, be sure to back up the data periodically.

It is recommended that important files are backed up to magnetic tapes. This enables the damage to be minimized in case of emergency including sudden vibration or shock and power shutdown caused by power interruption.
