RX2540 M2 Upgrade and Maintenance Manual 143
7 Hard disk drives (HDD) and solid
state drives (SSD)
Safety notes
V CAUTION!
● The HDD must not be removed from the installation frame by anyone
except a service technician.
● HDD/SSD modules must all be marked clearly so that they can be
reinstalled into their original mounting locations after an upgrade.
Otherwise, data may be lost.
● Do not touch the circuitry on boards or soldered parts. Hold the
metallic areas or the edges of the circuit boards.
● Before removing an HDD, wait for about 30 seconds until the disk has
stopped spinning completely.
● When an HDD is starting up, a resonant noise may be audible for a
short while. This does not indicate a failure.
● Depending on the OS, you can configure the write cache settings for
the HDDs. If a power failure should occur while the write cache is
enabled, cached data may be lost.
● When disposing of, transferring, or returning a hard disk or SSD, wipe
out the data on the drive for your own security.
● Rough handling of HDDs may damage the stored data. To cope with
any unexpected problems, always back up important data. When
backing up data to another HDD, you should make backups on a file
or partition basis.
● Handle the HDD and SSD on a shock and vibration free surface.
● Do not use the HDD and SSD in extremely hot or cold locations, or
locations with extreme temperature changes.
● Never attempt to disassemble the HDD or SSD.
● For further safety information, please refer to chapter "Important
information" on page 49.
