Hard disk and solid state drives
The hard disk drives which can be ordered for the PRIMERGY RX900 S1 are 
supplied already mounted in an installation frame so that defective hard disk 
drives can be replaced and new hard disk drives can be added during operation. 
The hard disk drive/solid state drive and the installation frame together make up 
the HDD/SSD module.
This section provides information on how to install or remove HDD/SSD 
modules and how to replace the SAS backplane. For information on SAS RAID 
controllers controlling the HDD/SSD modules see 
.

CAUTION!
The hard disk drive must not be removed from the installation frame 
by anyone except a service technician.
The HDD/SSD modules (drives) must all be marked clearly so that 
they can be put back in their original places after an upgrade. If this 
is not done, existing data can be lost.
The hot-plug function is only possible in conjunction with a 
corresponding RAID configuration.
Further information about the RAID configuration or RAID level can 
be found in the RAID controller documentation.
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, 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. 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 unit, wipe out 
the data on the drive for your own security.
