NOTICE 
 
Hot swapping 
In devices with removable rack, you can replace the drive without turning off the device. 
Replacement in devices without a removable rack may only take place when the device is 
turned off. 
The new hard disk can be integrated into the RAID system at operating system level with 
the RAID software. This is not possible at BIOS level. 
 
Points to note if the hard disk is replaced when the computer is turned off 
Only a hard disk that was active and functioning correctly when you booted can later be 
included in the RAID system.  
To be able to boot from the RAID system, you must place this first in the list of bootable 
sources in the BIOS "Boot" setup menu. Otherwise, the system will boot from the hard disk 
you have just installed and the message "Operating system not found" will be displayed.
