XtendLan RAID SATA 4C User’s Guide 1. System Board 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 ON Master OFF Slave SW3 SW4 SW5 SW6 SW7 Cable Select Upgrade N.C Software / / Default Default Hardware / / Default SW1 … SW2 … SW3 … SW4 … SW5 … Adjust HOST as MASTER or SLAVE Default OFF, if adjust to CABLE SELECT, then set SW1 at MASTER Default OFF, when upgrade firmware need to switch to ON Default OFF 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 2.8 Output PIN header PIN Title Description PIN 1 N.C N.C PIN 2 N.C N.C PIN 3 N.C N.C PIN 4 N.C N.C PIN 5 HDD-X1- Access When HDD X1 R/W, is able to connect LED PIN 6 HDD-X0- Access When HDD X0 R/W, is able to connect LED PIN 7 HDD-Y0- Access When HDD X0 R/W, is able to connect LED PIN 8 HDD-Y1- Access When HDD X1 R/W, is able to connect LED PIN 9 Power LED Able to connect with power indicated LED PIN 10 Access LED PIN 11 Buzzer Power Able to connect with HDD reading & writing LED Control Buzzer to be ON or OFF mode PIN 12 Total Fail PIN 13 Temp Sensor PIN 14 GND If any failure happen then pin is set to high and is possible connect with LED. Able to connect with one set of thermal resistance sensors. (GND) Ground PIN 15 3.3V Able to provide 3.3V / 100 mA power PIN 16 5V Able to provide 5V / 500 mA power 2.9 LCD header Connecting with 4 bit LCD module that is able to monitor RAID-SATA-4C status by LCD.
