Xcellon drd-401, User Manual

Span (Big)

Span mode links all the disk drives installed in the enclosure, so they can function as a single 
drive with combined storage space. This mode is similar to RAID 0 mode, but it does not stripe 
the data.

There are two ways to configure the RAID mode—via the included software or hardware. To 
configure the RAID mode via software, use the included RAID configuration software.

To configure the RAID mode via hardware, follow these steps:

1. 

Make sure the DRD-401 is turned off.

2. 

Clear the current RAID mode by pushing the RAID mode switches into the up position.

3. 

Press and hold the Set button. While holding the Set button, press and release the 
Power button to turn on the DRD-401. The DRD-401 will emit a beep as it turns on. 
Continue holding the Set button until you hear a second beep.

4. 

After the DRD-401 emits the second beep, release the Set button and press the Power 
button again to turn off the unit.

5. 

Set the RAID mode switches to the desired configuration, as shown in the image below:

6. 

Press and hold the Set button. While holding the Set button, press and release the 
Power button to turn on the DRD-401. The DRD-401 will emit a beep as it turns on. 
Continue holding the Set button until you hear a second beep. At this point, the DRD-
401 will be recognized in the reconfigured mode.

After reconfiguring the RAID mode, you will need to format. You may also need to initialize 
your disk drives.
