• Before installing an internal hard disk unit, turn off the server and all peripheral
devices, and unplug all power cables from the server. Failure to do so may
cause electric shock ( "1.4.3 Turning Off the Server" (p.32)).
When an array system is configured (RAID1, RAID1+0, RAID5, and RAID6),
an internal hard disk unit can be replaced without shutting down the server.
• The circuit boards and soldered parts of internal options are exposed and can
be damaged by static electricity. Before handling them, first touch a metal part
on the server to discharge static electricity from your body.
• Do not touch the circuitry on boards or soldered parts. Hold the metallic areas
or the edges of the circuit boards.
• Before removing the unit, turn the power off and wait for about 30 seconds until
the disk stops spinning completely.
• When the hard disk unit is starting up, you may hear a resonant noise for a
while, but this does not mean a failure.
• Depending on the OS, you can configure the write cache settings for the hard
disk drives. However, disable the write cache for use in this server. If the power
failure should occur while the write cache is enabled, cached data may be lost.
• When disposing of, transferring, or returning a hard disk unit, wipe out the
data on the drive for your own security. Contact an office listed in the "Contact
Information" of "Start Guide" regarding repairs of the hard disk units.
• Rough handling of hard disk units can damage the stored data. To cope with
any unexpected problems, always back up important data. When backing up
data to another hard disk drive, you should make backups on a file or partition
basis.
• Use the unit in a dry place with low dust levels.
• Be careful not to hit the hard disk unit or bring it into contact with metallic
objects.
• Use the device on a shock and vibration free surface.
• Keep the device away from direct sunlight and from radiators or other heat
sources.
• Do not use the unit in extremely hot or cold locations, or locations with extreme
temperature changes.
• Never attempt to disassemble the hard disk unit.
