Installation
1. Use the provided key to unlock the front door if needed and open it.
2. Insert a drive into each bay as desired, SATA connectors first, label side up as 
shown, then press the drive firmly into place.
3. Connect one Host cable to a computer. The unit can only use one host 
connection at a time.
4. Make sure the AC input switch is set correctly, then connect the power cord to 
an AC  outlet.
5. Set the AC power switch on the rear to ON, then press the power button 
behind the front door to turn on the unit.
To remove a drive, pull the Eject Lever until the drive disengages from t\
he 
internal connector then pull the drive out.
Hot Swapping drives
The R1ESU3F unit supports hot 
swapping (inserting or removing 
drives while the drives are 
running and connected to a 
computer). In JBOD Mode, the 
eSATA controller on the computer 
must also support hot swapping - 
be sure to confirm this before 
attempting to insert or remove 
drives while the system is 
running. Also be sure to practice the appropriate safe removal procedure before 
proceeding. Failure to practice safe removal procedures will result in l\
oss or 
corruption of data.
Port Multiplier Compatibility
When configured as a set of individual drives and connected to an eSATA host 
adapter, the Port Multiplier will only work with a Port Multiplier aware host. \
This 
includes setting up the unit with more than one array. Identify your host controller 
and check with its hardware manufacturer if you are unsure. Addonics offers 
several Port Multiplier aware host adapters.
Using identical drives for all settings other than JBOD or LARGE is stro\
ngly 
recommended. Creating a LARGE array using drives that have different proper -
ties will use all space on all members, and performance will match that \
of the 
member in use during any particular I/O operation. Creating a RAID using\
 drives 
that are not all the same size will result in all members using only as \
much space 
as the smallest member. Creating a RAID using drives that have different 
performance will degrade the overall performance of the array.

Port Multiplier Modes
The Port Multiplier supports individual drives (JBOD Mode), several ty\
pes of RAID 
and some non-RAID drive sets. Each configuration has different properties and 
requirements, as follows:
JBOD Mode (Individual Drives)
Number of drives: at least 1
Unit capacity: N/A (100% of each individual drive)
Spares: no
Fault tolerance: none
JBOD mode offers all connected units to the host adapter, no RAID is defined at 
all.
NOTE: JBOD mode requires a SATA controller featuring Port Multiplier support for 
eSATA connections.
NOTE: Optical drives can only be configured as JBOD using an eSATA connec-
tion.
RAID 0 (Stripe set)
Number of drives: at least 2
Unit capacity: size of each member times number of members.
Spares: no
Fault tolerance: none - if any member is lost all data is lost.
RAID 0 “stripes” the file system across the array by placing “c\
hunks” of data 
sequentially between drives in a specific order.
RAID 1 or 10 (Mirror set, Stripe of mirror sets)
Number of drives: 2 (RAID 1) or 4 (RAID 10).
Unit capacity: size of one member (RAID 1) or size of two members (RA\
ID 10).
Spares: yes – if EZ mode is not disabled and 3 (RAID 1) or 5 (RAID\
 10) drives are 
present, the array will be initialized with a spare.
Fault tolerance: RAID 1 can withstand the loss of one drive without losi\
ng data. 
RAID 10 can withstand the loss of one drive from each mirror set without\
 losing 
data.
RAID 1 works by duplicating the exact same data on two drives.
RAID 10 works by using two RAID 1 sets configured as members of a RAID 0\
. 
Disks 1 and 2 are mirrored, disks 3 and 4 are mirrored, and the two mirr\
or sets are 
striped together.
RAID 3 (Stripe set with dedicated parity)
Number of drives: at least 3
Unit capacity: size of one member times number of members minus one.
Spares: yes
Fault tolerance: can withstand the loss of one drive without losing data\
.
RAID 3 works by striping data for individual I/O blocks across all membe\
rs except 
one, which contains parity data for the stripe set computed internally b\
y the Port 
Multiplier. In the event of failure, the missing information can be calculated usi\
ng 
the parity information.

RAID 5 (Stripe set with striped parity)
Number of drives: at least 3
Unit capacity: size of one member times number of members minus one.
Spares: yes
Fault tolerance: can withstand the loss of one drive without losing data\
.
RAID 5 works by striping entire I/O blocks across all members of the set\
, with 
each member taking turns carrying parity data computed by the Port Multi\
plier. In 
the event of failure, the missing information can be calculated using th\
e parity 
information.
CLONE (Mirror set)
Number of drives: at least 2
Unit capacity: size of one member.
Spares: yes
Fault tolerance: can withstand the loss of any number of drives without \
losing data 
as long as at least one complete member remains online. CLONE mode works\
 the 
same way as RAID 1, by maintaining a complete copy of the entire set of \
data on 
each drive.
LARGE (Spanned set)
Number of drives: at least 2
Unit capacity: 100% of all drives together regardless of differences in size
Spares: no
Fault tolerance: cannot withstand the loss of any drives without losing \
data. 
However, some data may be recovered as long as the drive(s) carrying the file\
 
system data (boot record, directory, etc.) remain online. LARGE mode is neither a 
RAID nor is it a JBOD. It works by declaring the sum of all available sp\
ace of the 
member drives as a single unit, without striping the data. As each member is filled, 
new data is stored on the next.
Notes about Spare Drives
If any kind of array is defined, all individual drives not configured as\
 array mem -
bers will be offered to the host adapter as separate units. Only the fault-tolerant 
modes (RAID 1, 10, 3, 5 or CLONE) will make use of a spare – indivi\
dual drives 
will not be used at all and are not accessible with RAID 0 or LARGE.
To create an array with one or more spares, set or modify the RAID mode w\
hile 
the spares are disconnected from the Port Multiplier. Afterward, any individual 
drives connected when an array is present are considered spare. Spare dr\
ives 
must be equal to or larger in size than the smallest member.
When a drive fails on a fault-tolerant RAID, if a spare is present the P\
ort Multiplier 
will automatically begin rebuilding the array onto the spare.

Configuring the Port Multiplier Using Switches
Resetting the RAID
NOTE: This procedure destroys all RAID data. It should not harm individual dri\
ves 
or their contents; however, creating backups of all data is strongly recommended 
before proceeding.
Be sure the port multiplier is connected to an active host before procee\
ding. The 
port multiplier will not complete the process if it has no host connecti\
on.
1. Power down the unit and set the switches to the desired RAID Mode.
2. While holding the SET/RESET button, turn the unit on. A long beep will sound 
from the Port Multiplier. The SET/RESET button may be released once the long 
beep starts.
Shortly after releasing the button, the port multiplier should “chirp\
” to indicate the 
process is complete. If instead of a chirp the Port Multiplier sounds a \
series of 
short beeps, an error has occurred during the process.
Setting or Modifying the RAID Mode
NOTE: Setting or modifying the RAID mode destroys all data.
Be sure the port multiplier is connected to an active host before procee\
ding. The 
port multiplier will not complete the process if it has no host connecti\
on.
1. Follow the procedure for resetting the RAID Mode.
2. Power down the unit and set the dip switch to the desired RAID Mode.
3. While holding the SET/RESET button with a ballpoint pen, turn the unit on. A 
long beep will sound from the Port Multiplier. The button may be released once the 
long beep starts.
Shortly afterward, the port multiplier should “chirp” to indicate \
the process is 
complete. If instead of a chirp the Port Multiplier sounds a series of s\
hort beeps, 
an error has occurred during configuration of the array.
RAID Mode Switches  (SW1:3 – SW1-5)
The RAID Mode switches define what type of RAID will be initialized when\
 the unit 
is powered up while the button is held down, as follows:
Sw itc h P ositi o n  1 2 3 
JB O D ( Indiv id u al  Dr iv e s) * F ACT ORY D EFA UL T S ETT ING O FF   OFF   OFF  
RA ID 0 O N O N O N 
RA ID 1 O R 1 0  ON  ON  OFF  
RA ID 3 O N O FF  O FF  
RA ID 5  OFF   ON  OFF  
CL ONE  OFF  O N O N 
LA RG E  ON  OFF   ON

Configuring the Port Multiplier Using the JMicron RAID Manager
Windows users may install the JMicron HW RAID Manager application locate\
d on 
the SATA Controller CD, or download it from 
http://addonics.com/drivers/driver_list.php. In the CD, browse to Config\
uration 
Utilities → JMB393.
Mac and Linux users may download those versions of the same utility from\
 
http://addonics.com/drivers/driver_list.php under “Port Multiplier & \
Hub.” The 
JMicron RAID Manager can be used to create, modify, and monitor the health status 
of the RAID drives, and provide status alerts with dialog boxes and even\
 email. 
When configuring the RAID mode using the RAID Manager application, it is\
 strongly 
recommended to leave the dip switch in the factory default setting.
Setting or Modifying the RAID Mode
This procedure briefly describes the steps for using the Jmicron RAID Ma\
nagers 
Basic Mode to create an array. The example shown is a LARGE set. There are 
other options available in the Advanced Modes, including building arrays using 
specified drives, setting up email notifications, and updating the firmw\
are – which 
are not discussed in this user guide.
After starting the Jmicron RAID Manager, the first screen will show the status of any 
Port Multipliers detected and any drives connected. Shown below is a Por\
t Multiplier 
with a variety of five drives connected:
On the left pane is “Controller 1” which is the first port multipl\
ier detected by the 
software. Shown in a tree view are the five drives, listed as P0-P4. These are 
currently individual drives. On the right pane is a listing of the drive\
s and below that 
is a graphical view of each drive. “Disk 1” through “Disk 4”\
 indicate which physical 
port the drive is connected to. For the AD5HPMSXA, AD5HPMRXA-E, and 
AD5HPMREU this refers to ports P0-P4. On the CPR5SA unit, this refers to HD0-
HD4. On the AD5EHPMEU3 this refers to D1-D5. On RAID Tower products this 
relates to the drives mounted left to right or top to bottom, except in \
cases where a 
drive map is included showing otherwise.

Next, click the Basic RAID Configuration tab and select the type of RAID\
 desired. 
Note that RAID 1 is currently disabled as an option since more than two \
individual 
drives are available, and DELETE ALL RAID is disabled since there are currently no 
arrays to delete. Shown below is the same set of drives being selected a\
s a LARGE 
array.
Finally, click Apply. The Jmicron RAID Manager will confirm the operation with a 
reminder that existing data on the drives will be lost, then perform the\
 RAID configu -
ration and report with a dialog box when it is complete.

The RAID and Disk Information screen (shown when the program was launch\
ed) 
will now show the Port Multiplier with an Array. The drives are now listed as 
M0-M4, indicating they are members of the array. If spares are present 
(individual drives added later, and the EZ switch is in the OFF position), they 
would be listed as S0, S1, etc. On the right pane, the RAID Level, statu\
s, capac -
ity and members that are online are listed. Status will show “Normal”\
 (all mem -
bers on line), “Degraded” (a fault-tolerant array with a drive f\
ailure needing 
service), “Rebuilding” (a fault-tolerant array in the process of\
 reconstructing lost 
data onto a spare) or “Broken” (an array that has lost all data)\
.
In the event of a drive failure, the Jmicron RAID Manager will present a\
 dialog 
box such as the one shown below, even if it is currently minimized to the system 
tray:
