Overview
The backplane is a high performance economical solution for users who has sufficient SAS host
ports on MB or RAID/HBA to accommodate 4 disks in the system.
The passive backplanes support state-of-the-art SAS 6Gbps HDD/SSD and also backward
compatible with SATA 6Gps and SATA 3Gps HDD/SSD.
Basically,4 SATA7P connector can support up to 4 disk bays.
The 2pcs of 1*4Pin-P5.08 power receptacles support up to 5V(10A)/12V(10A) current to satisfy
the power needs of fully loaded disk drives
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 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.

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.
The LEDs behave by following SGPIO signal coming through customized cable. 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.
