Loosen the 5 screws at the back of the tower for 
the cover using a Philips screwdriver. Lift the 
cover and pull slightly toward the rear of the tower 
to disengage and remove.
Power LED: lit when RAID Tower is on .  
Host LED: lit when array group is connected, blinks 
during array activity.

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.
 
Installing drives into the 
RAID Tower XIII
1.  Be sure the lock on each drive doors 
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 the yellow label on the 
inside of the drive door – with drive door 
swing open at the 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 
the slot will cause the drive damage or 
permanent damage to the Disk Array. 
3.  Once the drive is all the way into the 
driver slot, close the door all the way until 
the drive door latches securely. This will 
engage power and data connection with the 
hard drive. The LED light for the drive slot 
should light if the Disk Array already is 
powered on. You may lock the drive door 
with the key.
4.  To remove the hard drive from the 
Disk Array, simply follow the steps 2-3 in 
reverse.

							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 beeps, an 
error has occurred during configuration of the array.
Windows users may install the JMicron HW RAID Manager application locate\
d 
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 stro\
ngly 
recommended to leave the dip switch in the factory default 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 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.

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\
d.
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.
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.
