Overview
InWin backplanes (without Expander) are high performance and cost effective solution for
supporting Intel Purley platform by adding NVMe support.
The passive backplanes support state-of-the-art SAS3 12Gbps HDD/SSD and also backward
compatible with SAS 6Gbps, SATA 6Gps and SATA3Gps HDD/SSD. The backplane supports
NVMe SSD through OcuLink x4 connectors.
Basically, one single SFF-8621 (SFF-8643 MiniSAS HD connector substitute) connector can
support up to 4 disk bays. 2 of them are so called Hybrid that further support NVMe SSD via
Oculink x4 connectors.

LED Behavior
Disk Bay LED
Blue LED:
Disk Insertion Indicator –
Turned on whenever disk drive is properly installed.
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 to SFF-8621 cables. The SGPIO Jumper setting is
enabled the LEDs behave according to the SGPIO signals.
For NVMe application, The LEDs behave according to the VPP over I2C signals from NVMe

Model : IW-RS216-07 Slim Hybrid Backplane User Manual PAGE 10 OF 12
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 (forActivity) 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.
System Alarm LED
There is a FAIL LED design on the Backplane to indicate Over-Temperature for indicating
system fault.
Overheat:
When the system temperature at the backplane area is going beyond 45°C the Temp Fail
triggered and Fail LED blinks in 2Hz rate. Goes off when temperature is going under 45°C.

Firmware Upgrade
The passive backplanes are planted Nuvoton M058 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. Require Nuvoton ARM Cortex-M0 programming tool. Nu-Me or Nu-Link and install
Nuvoton ICP Programming tool software.
2. Connect Nu-Link USB end to a host and the SWD end to Backplane ICE connector for

Model : IW-RS216-07 Slim Hybrid Backplane User Manual PAGE 12 OF 12
each MCU.
3. Make sure device is connected and select the binary file being programmed and then
click on Start button to program firmware.
4. Please refer to http://www.nuvoton.com/resource-
files/NuLink_Adapter_User_Manual_EN_V1.01.pdf for more details.
