1 Overview IN WIN backplanes (without Expander) are high performance economical 8 solution for users who has adequate SAS connection ports on motherboard or RAID/HBA card to accommodate the disks in the system. The passive backplanes support state-of-the art SAS3 12Gbps HDD/SSD and also backward compatible with SAS 6Gbps, SATA 6Gps and SATA 3Gps HDD/SSD.
Jumper Settings System indicators and buttons are designed for chassis by connecting 2-wire cable from front panel (if existed) to the jumpers on the backplane to facilitate the alarm system accordingly. The definitions of the Jumpers on the backplane are as below. Jumper Function Details...

4 LED and Buzzer Behavior 4.1 Disk Bay LED There are 3 color of LEDs for each bay to indicate HDD status by illuminating in different color and format. Blue LED: Power Indicator. Turned on whenever disk drive is properly installed. Green LED: Activity indicator.
4.2 System Alarm LED There is a FAN FAIL LED and a TEMP FAIL LED designed on the Backplane to indicate Fan Fail and Over-Temperature separately. Fan Fail: When the Fan RPM is lower than 75% of the expected speed the Fan Fail indicator goes ON.

and stops beeping when alarm is disappeared. ◆ 1 short beep(B—B—B) stands for Fan Fails ◆ 2 short beeps(BB—BB—BB) stand for Over-Temperature ◆ Press Mute Button to disable buzzer beeping and will be retriggered when either failure occurs again.
5. Smart Fan Control IN WIN’s Backplane is implemented Smart Fan Control feature by automatically detecting the existences of the Fan Modules and intelligently control the Fan RPM per the system temperature being detected by 1 or 2 thermal sensors on the backplane.

How it works? 1. Fan module auto-calibration would launch in every system boot. The profile would then be recorded and used until next reboot. 2. Backplane starts fan calibration and calculates the corresponding PWM duty cycle for each level. There are totally 8 speed levels to be calculated and used until next system boot.
6. Firmware Upgrade The passive backplanes are planted Nuvoton M052 series MCUs for hosting disk LED indication, Fan speed control and system fail alarm. These MCUs are preprogrammed in manufacturing. In most cases, the MCUs are not required to reprogram unless there is issue needed to fix. How to upgrade firmware? 1.

3. Make sure device is connected and select the binary file being programmed and then click on Start button to program firmware.
