XtendLan RAID SATA 4C
User’s Guide
2. Setting and Connecting
2.1. DC INPUT=> connect power connector of DC power in order to provide the power to RAID-SATA-4C.
2.2. RS232 =>GUI software is used for connecting the OS from HOST to monitor RAID-SATA-4C status.
PIN 1 TX
PIN 2 RX
PIN 3 GND
2.3. SATA TO HOST / ATA-133 FOR HOST =>
Please select SATA or ATA-133 to connect with HOST. Is not possible to connect both simultaneously.
2.4. BZ => The buzzer warning sound if HDD and fan failed
2.5. SW => Total for 7 sets of functions as below instruction:
Setting Mode
SW1 SW2 SW3 SW4 SW5 SW6 SW7
ON Master Cable Select Upgrade N.C Software / /
OFF Slave Default Default Default Hardware / /
SW1 … Adjust HOST as MASTER or SLAVE
SW2 … Default OFF, if adjust to CABLE SELECT, then set SW1 at MASTER
SW3 … Default OFF, when upgrade firmware need to switch to ON
SW4 … Default OFF
SW5 … Set ON, works as JBOD, SW6, SW7 without
Set OFF, works as independent hardware RAID, mode is selected by SW6 –SW7.
SW6 - SW7 …
Use 4 HDD on X0/X1/Y0/Y1 – When SW6 = OFF & SW7=OFF, RAID mode is RAID 0 (striping)
Use 4 HDD on X0/X1/Y0/Y1 – When SW6 = OFF & SW7=ON, RAID mode is RAID 0+1
Use 4 HDD on X0/X1/Y0/Y1 – When SW6 = ON & SW7=OFF, RAID mode is NRAID
Use 4 HDD on X0/X1/Y0/Y1 – When SW6 = ON & SW7=ON, RAID mode is JBOD
2.6. FAN => There is two sets of fan, which use 3 wires 12V DC fan. The pin assignment definition is as
below:
PIN 1 GND
PIN 2 12V
PIN 3 CLK
2.7. HOT SWAP DECTECT = Design for Hot Swap Function, Jumpers X0/X1/Y0/Y1
When hot-swap function demanded and hot-swap trays available then set for HDD-1 jumper X0 to ON (set
Jumper). Same setting for HDD-2 (Y0 to ON), HDD-3 (X1 to ON), HDD-4 (Y1 to ON).
However, if you do not have hot swap assembly for HDD, please short circuit on X0 AND X1 AND Y0 AND
Y1
