RAID Rack with Port Multiplier Compatibility
The redundant power supply provides 500W of power. Before turning on 
the main switch located on the front panel of the RAID Rack, connect and\
 
switch on both units in this power supply. If only one power supply is 
running, an audible alarm will sound.
Connect the unit to a computer using the provided mini SAS cable before \
powering up the RAID Rack.
Power Supply and Host Connection
Note: When configured as a set of individual drives, the Port Multiplier\
 
will only work with a Port Multiplier aware host. Identify your host con\
trol -
ler and check with its hardware manufacturer if you are unsure. Addonics 
offers several Port Multiplier capable host adapters.

1. Be sure the lock on each drive door is in an unlock position. If not,\
 use the key 
    that comes with the Disk Array to unlock the drive door. Pull on the door lever to 
    swing open the drive door all the way. 
2. Slide a 3.5” SATA hard drive into the drive slot with the drive connector side 
    facing in. Be sure to orient the hard drive correctly as shown in th\
e yellow label 
    on the inside of the drive door – with drive door swing open at t\
he bottom, the 
    top of the hard drive should face to the right. The drive should slide all the way 
    into the slot with very little resistance. Forcing the drive into th\
e slot will cause 
    drive damage or permanent damage to the Disk Array.
3. Once the drive is all the way into the drive slot, close the door all\
 the way till the 
    drive door latch securely. This will engage power and data connection with the 
    hard drive. The LED lit for the drive slot should lit if the Disk Array already 
    powered on. You may lock the drive door with the key.
4. To remove the hard drive from the Disk Array, simply follow the step 2 – 3 in 
    reverse.

Resetting the RAID Mode
NOTE: This procedure destroys all RAID data. It should not harm individual 
drives or their contents; however, creating or running backups of all data is 
strongly recommended before proceeding.
1. Power down the unit and set the dip switch to the factory default setting (all 
switches OFF).
2. While holding the SET button with a ballpoint pen, turn the unit on. A long 
beep will sound from the Port Multiplier. The SET button may be released 
once the long beep stops.
Setting or Modifying the RAID Mode
NOTE: Setting or modifying the RAID mode destroys all data.
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 button with a ballpoint pen, turn the unit on. A long 
beep will sound from the Port Multiplier. The SET button may be released 
once the long beep stops.
If instead of a long beep the Port Multiplier sounds a series of short b\
eeps, an 
error has occurred during configuration of the array.
Windows users may install the JMicron HW RAID Manager application 
located on the SATA Controller CD. In the CD, browse to Configuration 
Utilities → JMB393. The JMicron HW RAID Manager can be used to create, 
modify, and monitor the health status of the RAID drives, and  provide status 
alerts. When configuring the RAID mode using the RAID Manager application, 
it is strongly recommended to leave the dip switch in the factory defaul\
t 
setting.
Using identical drives for all settings other than JBOD or LARGE is stro\
ngly 
recommended. Creating a LARGE array using drives that have different 
properties 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 u\
sing 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.

BZS Switch (SW1:1):
The BZ switch is used to silence the audible alarm buzzer. The OFF position 
permits the audible alarm, and the ON position silences the audible alar\
m. 
The BZ switch has immediate effect.
EZ Switch (SW1:2):
The EZ (spare) switch inhibits spares when ON. When in the OFF positio\
n, 
all individual drives (not defined as members of an array) are conside\
red 
spare. Should a RAID become degraded, when the EZ switch is in the OFF 
position a spare drive will be used automatically to rebuild the RAID, i\
f 
present. EZ mode is determined when the unit is powered up. Changing the\
 
switch will have no effect until the unit has been re-powered.
RAID Mode Switches M2, M1, M0 (SW1:3 – SW1-5)
The RAID Mode switches define what type of RAID will be initialized when\
 
the unit is powered up while the RAID Mode button is held down. Each typ\
e 
of RAID has different properties and requirements, as follows:
           
              1 Audible alarm is recommended at all times.
              2 EZ mode has no effect in JBOD mode.
              3 Disabling EZ for RAID 0 and LARGE is strongly recommende\

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 
connection.
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 secto\
rs 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 m\
irror 
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 by th\
e 
Port Multiplier. 
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 \
Multiplier.
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 space of the member drives as a single unit, withou\
t 
striping the data. As each member is filled, new data is stored on the next.
