Replacing a defective hard disk drive in the RAID system

Hard disk drives can be replaced during operation in the removable drive bay in connection
with a configured RAID1 system or RAID5 system. This functionality is referred to as "Hot
Swap".
Note
If you have configured a non-RAID system with several hard disk drives, you need to turn off
the device before you replace a hard disk drive.
Damaging the drive
If you replace a drive while it is active, the drive and data are corrupted. The device can no
longer be operated without problems.
Replace the drive in the removable drive bay when the "HDD" status display of the device
is not lit.
Observe the EGB guidelines. Always replace the drive with a new drive of the same type and
capacity.
Mounting locations for hard disk drives in the RAID1 system
Hard disk drives for a RAID1 system can be installed internally in the device or on the front in
a removable drive bay.
Note
The replacement of a hard disk drive with removable drive bays and in the RAID system can
be performed without shutting down the device. An internal hard disk drive may only be
replaced when the device is switched off.
The new hard disk drive can be integrated into the RAID1 system at operating system level
with the RAID software. Synchronization may take several hours, depending on system load.
