4. Take the transport paper board out of the device.
5. Slide 4 HDDs into the chassis and make sure they are securely installed
in order from top to bottom.
6. Reinstall the metal frame that was removed in Step 3.
Please make sure the bottom of the frame stays inside the track
before closing the cover.
7. Connect the power supply to the device, plug in either USB-C cable
in the rear panel and power on the device. Make sure computer is ON.
Make sure the HDD is securely
installed first at all times.
Otherwise the PC may not recognize
the device.

SETUP
RAID Mode Setup
1. First install the HDD from up to down in the enclosure. Make sure the PC is on
and ready to go, Power on the device.
2. The Device is built in 2 sets of RAID, and each RAID is constructed by 2 HDDs.
There are two sets of Raid mode need to be setup properly before you using
this device, finds " SET 1" and "SET 2" in the front panel on this device.
3. The setup procedures are as follows:
There are several mode options for HFR7-SU31CH, Single, JBOD (Spanning),
RAID 0 (Striping) and RAID 1. The enclosure is not default to any of the above.
So If you just put hard drives in without setting a mode to use, the enclosure
will just turn off after a few seconds of turning it ON.
‧Changing RAID mode may cause data lost,
backup your data before making changes.
‧Do not use hard drives containing data
to create a RAID array.

Press and hold the "SET 1" button until the RAID option
light starts to flash then let go of "SET 1" button.

When using RAID function, HDDs with the same brand,
model and capacity is strongly recommended.

Spanning concatenates multiple hard drives as a single large volume;
resulting in a seamless expansion of virtual volumes beyond the physical
limitations of separately connected hard drives. The data are written from
HDD1 to HDD2.
Raid 0, JBOD Spanning Only , Non-Single JBOD
Spanning (BIG) JBOD
RAID 0
Striping is a method of concatenating multiple hard drives into one logical
storage unit. It is the automated process of writing data across .multiple drives
simultaneously. Striping is used to increase the performance of disk reads.
The multiple hard drives will write data in “column” effect.
If one drive in a striped set fails, all of the data in the stripe set is lost.
RAID 0 Striping
Mirroring is the automated process of writing data to multiple drives simultaneously.
Mirroring is used to provide redundancy. If one drive fails, the redundant drive(s)
will continue to store the data and provide access to it. The failed drive can then
be replaced and the drive set can be rebuild.
Mirroring
RAID 1
Simulate as a 4-bay non-RAID enclosure,
and you can separately access 4 hard drives.
Note：Do not use hard drive with data to create any RAID mode.

Initialization
Windows
If the HDD is uninitialized, you may have to initialize it by doing steps as followed:
At first click ''Start'', ''Execute'' on your PC and key in ''diskmgmt.msc''.
After that please press ''Return'' key.
1. Start disk initialization

Mac OS X 13 or later
1. Click ''Disk Utility'' icon.
2. HDD initialize...
Start disk initialization
Please enable GPT if the total capacity is more than 2TB and enable MBR
if the total capacity is less than 2TB.
Activate MBR if total volume is less than 2TB
Activate GPT if total volume is more than 2TB

Changing the RAID mode will cause data lost.
Please refer to the instructions when switching the RAID mode,
otherwise set up might fail.
When using RAID function, HDDs with the same brand, model and
capacity is strongly recommended.
When using RAID function, more than one HDD partition is not recommended.
Under Windows 7 / 8.1, users can enable GPT when initializing HDD with
a total capacity of more than 2TB.
If users enable MBR by mistake, in order to clean the partition table, you have
to switch to another RAID mode and do the RAID mode switch all over again
referring to Setup. Then go back to the RAID mode you want, repeat the previous
actions and enable GPT when initializing HDD.
For Macintosh users: the total capacity of more than 2TB could be recognized
only for the operation system is 10.4.11 Tiger or later.
Rebuild time is based on the capacity, e.g. it takes about 1 hour for 200GB.
When the USB cable is plugged out, the device goes to sleeping
mode automatically
.
To take the HDD out from the device, slightly press down the handle
and pull it out.
Setting up motherboard's power management in S3 is recommended.
(
For more details, please refer to the user guide of motherboard BIOS setting ).
If the device takes too long to initialize, please check if the HDD is securely
installed.
If there is noise with the fan, power off the device, unscrew the fan, take out the cover,
clean the fan and assemble it back.
Troubleshooting
14. If the noise is still present, you can change the fan with another identical fan of size
80 x 80 x 20 mm referring.
