Xcellon HDD-202 Manuale utente
User Manual
Thank you for choosing Xcellon.
The Xcellon HDD-202 is the most convenient way to create a
two-disk RAID system with internal-type SATA drives. The HDD-
202’s tray-less, top-loading bays enable easy access with simple,
tool-free installation—instead of dismantling your computer
and installing your drives, just insert the drives directly into
the dock. Five RAID modes deliver a variety of options when it
comes to read/write functions, data storage, and backup, and are
configured via the DIP switches located on the rear of the device.
The HDD-202 is equipped with a USB-C™port that is capable
of attaining SuperSpeed USB 10 Gbps transfer rates, when used
with compatible devices. Designed to work with hard disk drives
and solid state drives, the HDD-202 accommodates 2.5″laptop-
sized and 3.5″ desktop-sized SATA I/II/III drives with capacities
up to 8 TB. The dock supports plug-and-play and hot-swapping
and includes all necessary interface cables.

Plugging In and Setting Up
1. Use the included power adapter to connect the dock to an AC
power source. Make sure the dock is turned o by verifying that
the power LED is not glowing.
2. Use one of the included USB cables to connect the dock to the
corresponding port on your computer.
3. Align the SATA contacts on your disk drive and the dock, and
fully insert the drive into the dock.
4. Press the power button to turn on the dock. The power LED will
glow blue and the status LED that corresponds to your hard disk
will blink purple.
The HDD-202 works with one drive or two. In order to set up a RAID
system, you will need to install two drives.
If your disk drive has been formatted, your computer will notify you
that new hardware has been detected, and the drive will appear on
the Desktop, in My Computer, or in the Finder.
If the drive has not been formatted, or if your computer cannot read
or recognize it, you may need to format the drive. See Formatting
Your Disk on page 11.
The HD LEDs will change color depending on the current status
of the corresponding drive. The LEDs will glow blue during normal
operation, purple when a drive is active, and red if a drive is damaged.

RAID Mode Configuration
The RAID mode options are 0, 1, Span (Big), JBOD, and Port Multiplier.
The default mode is JBOD. Familiarize yourself with the advantages
of each RAID mode before making a selection.
Important! Before configuring the RAID mode, make sure to
back up your data. All data on the installed disk drives will be
eliminated during the configuration process.
Make sure that both drives have the same rotational speed (RPM).
When using RAID modes 0 or 1, it is recommended that both hard
drives have the same capacity. If possible, use identical drives.
RAID 0
RAID 0 mode stripes data in blocks across the two disk drives. This
mode links the drives installed in the dock, so they can function as a
single drive with combined storage space. If you are using two 100
GB drives, they will combine to function as a single 200 GB drive.
Figure 1. In RAID 0 mode, both disks will appear as a single disk on your computer.

RAID 1
RAID 1 mirrors the data in blocks on the two disk drives, so the exact
same data is stored on both drives. Data integrity is more reliable
in this mode than in RAID 0 mode, although there is less accessible
disk space and the transfer speed is slower. Mirroring makes it
easier to recover lost data if one of the RAID drives is damaged (see
Troubleshooting on page 16). Only one of the two drives is accessible
in RAID 1 mode.
Figure 2. RAID 1 mode, only one drive will appear on your computer.
When using RAID 0 and RAID 1 modes, you can use disk drives
of varying capacities, although the capacity will be limited to the
smallest of the disk drives. For example, if you are using a 100 GB and
a 250 GB drive, then the 250 GB will be limited to the smaller 100 GB
capacity, and the total combined capacity will be 200 GB.

JBOD
In JBOD mode, the two disk drives function independently of one
another. JBOD is an acronym for Just a Bunch of Disks.
Figure 3. In JBOD mode, both disks will appear on your computer.
Span (Big)
Span mode links the two disk drives, so they function as a single drive
with combined storage space. This mode is similar to RAID 0 mode,
but it does not stripe the data across the disks. Span mode is not as
fast as RAID 0, but it is more secure.

Port Multiplier:
In Port Multiplier (PM) mode, you can run up to 15 drives from a single
SATA port via a PM cable. In a PM setup, the drives connected to the
PM cable will function as a JBOD system.
Note: Separate power is required for the drives in a PM setup. All
the drives will share the same SATA speed, so they will be unable
to attain the maximum rate.
Configuring the RAID Mode
RAID modes are configured via the switches on the back of the dock.
To configure the RAID mode, follow these steps:
1. With both drives installed into the dock,
set the RAID mode switches to the desired
configuration as shown in the table to the right.
2. Press and hold the Set button for ten seconds.
This will start the RAID setup procedure, during
which the HD status LEDs will blink purple
intermittently.
3. After ten seconds, let go of the Set button. At
this point, the LEDs will have stopped blinking,
and your computer will have recognized your
drives in the new RAID mode.
Note: If your disks are formatted, then you will not need to reformat
them after reconfiguring the RAID mode, but you will lose your data. You
may need to initialize your disk drives after configuring the RAID mode.
If your computer does not recognize your disks after reconfiguring
the RAID mode, try rebooting the dock or your computer. For more
information, refer to Troubleshooting on page 16.
