System Reset Switch The 
System Reset
 switch on the front of the ioSafe R4 next to the power button. 
The System Reset switch allows you to perform three functions:  (1) re-install the ioSafe R4 
firmware, (2) reset the ioSafe R4 back to the factory default settings, and (3) change between 
X-
RAID
 and 
Flex-RAID
 mode. 
Typically, you should not need to resort to options (1) and (2) unless you have exhausted all other 
means of recovering your system.  You may want to re-install the ioSafe R4 firmware as a first step, 
if the ioSafe R4 had been working normally but a configuration change makes it inaccessible.  If this 
does not work and/or you wish to set the ioSafe R4 back to a factory default state, you can do so 
following the instructions below: 
To re-install the ioSafe R4 firmware
, use a paper clip to depress the switch while the 
system is off.  Continue to depress the reset switch while powering on the system and 
continue to hold the reset switch for 5 seconds afterward.  The disk LED’s will flash once 
to signify that the command has been accepted.  The firmware installation will take several 
minutes to complete.  The Status LED in the front will also be solid when the process is 
complete.  The installation will not affect the data on the ioSafe R4. 
Make sure not to 
press the reset switch for too long, otherwise a destructive Factory Default process 
will be started instead
 (see below). 
To set the ioSafe R4 device to Factory Default
, use the same process, except you must 
hold the System Reset Switch for 30 seconds after powering on the system.  You should 
see the disk LED’s flash for a second time to signify that the command has been accepted.  
Note that this process re-installs the firmware and resets the disk configuration,

OUT ANY DATA
 you may have had on the NAS. 
To change between X-RAID and Flex-RAID mode
, you will need to perform a 
Factory Default using the method described above.  Note that changing RAID modes will 
not preserve your data, so make sure to perform a backup before doing this.  During the 
boot process during Factory Default, there will be a 10-minute window where you can use 
RAIDar to select the desired volume setup.  RAIDar will display your ioSafe R4 with
