• Thunderbolt device chains can support up to six Thunderbolt devices. • There is no power switch on the Mercury Elite Pro Dual. As long as the power supply is connected, the device will turn on when it receives a data signal through the interface cable (USB 3.0 or Thunderbolt).
1. Remove the Mercury Elite Pro Dual from the retail box and the protective plastic bag. Set the Mercury Elite Pro Dual on its side and look at the bottom of the enclosure. Use a Phillips screwdriver to remove the two screws, as circled below in red.

Remove the packet of screws and use the screws as directed later in the assembly instructions. Note that the plastic shield over the circuit board is there by design and should not be removed. OWC DIGITAL - MERCURY ELITE PRO DUAL DEVICE SETUP...

5. Install the upper hard drive (HDD1), as shown below. Insert the SATA power and SATA data cables from the Mercury Elite Pro Dual into the SATA connector on the hard drive (NOTE: do not twist the black SATA data cable. Doing so could cause instability in the connection), then slide the hard drive to line up the screw holes in the hard drive with those on the inner chassis.

As shown below, the screw holes at the front of the outer enclosure are close to the silicone feet. The screw holes at the rear of the outer enclosure are farther away from the silicone feet. REAR FRONT OWC DIGITAL - MERCURY ELITE PRO DUAL DEVICE SETUP...

9. Once the front grill of the inner chassis sits flush with the edge of the outer enclosure, turn the Mercury Elite Pro Dual on its side again to look at the screw holes on the bottom. You should be able to see that the screw holes in the outer enclosure line up with the screw holes in the inner chassis.
Note that a data cable (Thunderbolt or USB) must be connecting the Mercury Elite Pro Dual to a computer in order for the device to power up. 4. Once the Mercury Elite Pro Dual powers up, it will be set to the new RAID mode.
In the event that one of the drives fails, the corresponding drive LED will turn solid red. If the Mercury Elite Pro Dual was configured as a RAID 0 or span, the data on the array is lost and the volume cannot be used. In a span, only the data stored on the failed drive is lost, although data recovery software will be required to recover the data from the other drive in the span.
RAID 0 or RAID 1. If the Mercury Elite Pro Dual is set up as a span or as a RAID 0, the array must be reformat- ted before it can be used again. If the device is set up in independent drive mode, you do not need to reformat the existing drive or the new drive.
Then, simply verify that both ends of your cables are properly plugged into the computer and the Mercury Elite Pro Dual. If the Mercury Elite Pro Dual is still not working properly, try connecting to another interface (USB or Thunderbolt) and see if the device works properly.
To ensure that your files are protected and to prevent data loss, we strongly suggest that you keep two copies of your data: one copy on your Mercury Elite Pro Dual and a second copy on either your internal drive or another storage medium, such as an optical backup, or on another external storage unit.
