1Overview
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.
Basically, one single SFF-8643 miniSAS connector can support up to 4 disk bays. There
are several miniSAS connectors and 29-pin high profile disk connectors on the
backplanes depends on the product model.
The backplane is 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 in the enclosure. The fan module speeds up and down upon the
temperature rises and falls in the enclosure.
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 and sounding the buzzer at the same time. Users
can then detect issue and take corresponding actions to resolve the issue according
to the failure type. As soon the issue disappears the alarm stops.
2 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.

JM1
Setting Function
1-3 Short SGPIO_0 Enable
3-5 short SGPIO_0 Disable
2-4 Short SGPIO_1 Enable
4-6 Short SGPIO_1_Disable
To enable/disable SGPIO
function. When SGPIO is
enabled, the Green and

controlled by MCU by
sensing the SGPIO signals
sent by RAID/HBA car.
SGPIO_0 is for disk 0 ~ 3
SGPIO_1 is for disk 4 ~ 7

3.2 SFF-8643 Mini-SAS connector:
Different model of backplane has different number of miniSAS connector.
Most of backplanes are supporting 12G SAS connection while SK35/ IW-
R400-03N is supporting 6G SATA only.
Since these backplanes has no expander. All the miniSAS connectors or
SATA connectors are directly wired to the 29-pin disk connectors.
