Storage Mode Denition for Supported RAID mode
Independent mode ( JBOD ) : Two independent storage disks. ( this is the factory default setting )
Speed mode ( Raid 0 ) : One large independent storage disk for fast data access, but no data redundancy.
Safe mode ( RAID 1) : Mirrored storage capacity allowing data protection.
Span : One large storage disk without fast data access and without data redundancy.
To Change the RAID model setting, Plesae follow the following procedures :
Step 1 Set the DIP switches at the back of the unit to the RAID Mode you need ( Figure 5 )
Step 2 Press the reset switch at the back for 10 seconds and release it
Step 3 Power O the unit and Power On it again
Step 4 The required RAID mode is now set
Important Remark :
1) Hard Disk will be re-formatted during RAID Mode change, make sure you have back up all data before make the change
2) To change the RAID mode from RAID 0, RAID 1 and SPAN to other setting, you need to set it back to PM / JBOD mode rst.
Then set it again to the RAID Mode you need as shown from Step 1 to Step 4 above
