CAUTION
Cautions concerning disk drives
A disk drive is an electronic device.
When handling one, take measures against static electricity, such as using a wrist
strap.
If you do not have a wrist strap, firmly place one hand on the unpainted metal surface of
the disk drive before handling it.
Mount three disk drives in the disk array unit at locations 00, 01, and 02 of the unit. If
these are not mounted, data may be lost.
Do not remove more than one of the drives at locations 00, 01, and 02 of the disk array
unit while the power to the unit is off. Moreover, do not turn off the power if more than
one of the drives at locations 00, 01, and 02 are removed. If you remove drives, data
may be lost.
When adding disk drives or changing the locations at which disk drives are mounted, be
sure to work on one at a time in powering them on. Install the next disk drive after
confirming that the installed disk drive is ready.
When installing a disk drive, lock the ejector after it has been inserted fully. Not
inserting it fully may cause failure.
Do not change the locations at which disk drives are installed if logical disks have been
configured. Data may be lost.
