Overview
INWIN’s 12G SAS3 Backplanes equipped with Broadcom 35x36R Expander provide an industry
leading high performance and high stability of data transfer for storage server solution.
The backplanes support state-of-the art SAS3 12Gbps HDD/SSD and also backward compatible
with SAS 6Gbps, SATA 6Gps and SATA 3Gps HDD/SSD. The backplane has 4 * SlimSAS
(SFF-8654) connectors and 4* U.2 (SFF-8639) connectors to accommodate 4 * 2.5”NVMe SSDs
per each backplane.
There are 3 MiniSAS HD (SFF-8643) wide ports on each backplane. one of them are defined as
host ports for connecting to RAID/HBA cards and the other is defined as the cascade port for
connecting to another backplane and/or storage enclosure (JBOD) by extending it to the rear
panel of the chassis through a SFF-8643 to SFF8644 cable.
1 piece of 2*3-Pin 5V and 1 piece of 2*4-Pin 12V power receptacles support up to
5V(24A)/12V(32A) current to satisfy the power needs of fully loaded HDDs (12 HDDs depends
on backplane model).
The backplane implemented with smart fan control feature to support wide variety of fan
modules by auto-calibrating the installed fan modules at system boot. This feature provides an
efficient way to control the thermal heat exhaustion by sensing the temperature on the
backplane. The fan module speeds up and down upon the temperature rises and falls in the
enclosure. Further, the backplane reserves a connector for adapting Fan PWM from
motherboard so backplane can leverage PWM request from motherboard and behave according
to the higher RPM number between MB and backplane.
Along with the smart fan control feature, a system alarming feature is also implemented to alert
users in case Fan module failure and/or system overheat occurs by illuminating the LED
indicator. Users can then informed of issue and take corresponding actions to resolve the issue
according to the failure type.

LED Behavior
Disk Bay LED
Blue LED:
Disk Insertion Indicator –
Turned on whenever disk drive is properly installed.
Green LED:
Activity indicator –
Stay off when idle and blinking (~8 Hz) whenever disk drive is being accessed.
RED LED:
Fail and Locate indicator –
Turned steady on when disk failure occurs. Blinking (1 Hz) when locating Disk, RAID
rebuild and RAID consistent check.
There are 2 parts of LED Management on the backplane. One is for SAS and another is for
NVMe. Please note that the disk slots can only accommodate SAS/SATA or NVMe disk at a
time since they share the same disk connector.
For SAS application, The LEDs behave by following SGPIO signal coming through
sideband bus inside the SFF-8643 cables. Please refer to Section 2 for SGPIO settings.
When SGPIO Jumper setting is enabled the LEDs behave according to the SGPIO signals.
When SGPIO is disabled, the RED LEDs (for Locate and Fail) do not behave while the
GREEN LEDs (for Activity) behave according to the signal from P11 (READY LED) of the
disk connectors.

Model : RS212-07 Hybrid EXP-BP (CUB) User’s Manual PAGE 13 OF 23
For NVMe application, The LEDs behave according to the VPP over I2C signals from NVMe
host controllers through sideband bus of OCulink or SlimSAS cables. Whenever the NVMe
host controller support VPP over I2C, the RED LEDs behave Locate, Fail and Rebuild
signals following VPP signals on the I2C bus. The Green LEDs (for Activity) behave
according to the signal from P11 (Activity) of the disk connectors.
Examples of NVMe connections to Broadcom RAID/HBA controller. Each pair of VPP over
I2C signal supports 2 pieces of NVMe disks LED management. The I2C bus is leaded to
odd-number NVMe connector (OCulink or SlimSAS) to manage its corresponding and the
following NVMe disks. For example, NVMe1 and NVMe2 LED management signal is form
NVMe1 connector’s sideband I2C bus, NVMe3 and NVMe4 LED management signal is
from NVMe3 connector’s sideband I2C bus and …etc.

Model : RS212-07 Hybrid EXP-BP (CUB) User’s Manual PAGE 14 OF 23

System Alarm
There is a system error LEDs designed on the Backplane to indicate system Error including
system Fan Fail and Over-Temperature.
System Fail Indicator:
JB3 is the jumper for system Fail Indicator. The System Fail indicator on the front panel
connect to this jumper to indicate system fan fails or system overheat when it occurs.
Fan Fail:
When the Fan RPM is lower than 50% of the expected speed the indicator goes ON. And it
would go off when the issue is resolved or not existed.
Overheat:
When the system temperature at the backplane area is going beyond 45°C the System Fail
LED is turned ON. And would be turned off when temperature is going under 44°C
Note:
When the system alarm is triggered, the Buzzer beeps along with it and stops
beeping when alarm is disappear.
1 short beep stands for Fan Fails
2 short beeps stand for Over-Temperature
Press Mute Button to disable buzzer beeps and will be retriggered when either
system error occurs again.

Model : RS212-07 Hybrid EXP-BP (CUB) User’s Manual PAGE 16 OF 23
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 two thermal sensors (RTB1/RTB2) on the backplane.
Thanks to Smart Fan Control feature the Fan connectors (FAN1/FAN2/FAN3/FAN4) on
backplane support wide variety of PWM driven Fan modules being used in the enclosure.
How it works?
1. Fan module auto-calibration triggered in every system boot. The thermal 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 sensed and used until next system boot.
3. The 8 levels of fan speed are mapped to the temperature readings detected by thermistor
spreading from 25 to 45 °C in 3.75 degree C step.
4. In normal operation, when the system temperature changes to next level, the fan module
would change speed accordingly. And, the Fan failure alarm would be triggered when the
RPM of the Fan module is dropped lower than 75% of its expected speed.
5. The fan module calibration and thermal profile are as below.
6. When an external PWM source joins, the output PWM duty is determined by comparing
the internal calculated PWM and external PWM and then select whichever is higher as
the output PWM to the fan modules.

Firmware Upgrade
Expander Chipset SAS35x36R Firmware Upgrade Description
The SAS3 backplane equipped with firmware upgrade feature through serial console in case
it is required. There are 2 firmware to be upgraded. One is Expander system firmware and
another is system configuration data. They are not necessarily to be upgraded at the same
time. Ether one can be upgraded independently when required.
How to upgrade firmware?
1. Out-Of-Band through serial console
2. In Band through SCSI Command
Out-Of-Band through serial console
IN WIN’s SAS-3 12Gps Backplane implements a serial UART port allowing users to conduct
firmware upgrade through it.
1. Require a proprietary serial cable IN WIN made.
Please note that the connector to Backplane varies depends on the backplane. The 07
series backplane UART port is redesigned with smaller form factor.
2. Require a host with a serial COM port.
3. Connect serial cable between Backplane and host.

Model : RS212-07 Hybrid EXP-BP (CUB) User’s Manual PAGE 19 OF 23
4. Configure serial port setting as 115200, N, 8, 1.
5. Command “fdl 0 0 y” for system firmware upgrade in serial console. Sending system
firmware through Xmodem.

Model : RS212-07 Hybrid EXP-BP (CUB) User’s Manual PAGE 20 OF 23
6. Command “fdl 1 0 y” in serial console for system configuration data upgrade. Sending
system firmware through Xmodem.
7. Reset system by typing “reset” command in serial console or power cycle to make new
firmware take effect.
