Description
Drawing
A
SATA/SAS
For connecting to a mainboard, this SATA/SAS 7-pin connector is applied.
A proper cable selection is essential as well to make sure good signal
integrity, which can be maintained for the whole connection path from
mainboard HDD devices.
B
Power
These two connectors are used to power four 3.5” hard disks, connected to
this backplane, and each can ensure that all drives are supplied with stable
power inputs. If the chassis fan is also powered by fan header (JF01), this
configuration is highly recommended.
C
Fan
There are two 4-pin headers for the PWM fan, and it is alternative solution
that the chassis fan can be powered and monitored by this backplane
instead of motherboard. If the chassis fan is connected to a mainboard,
user needs to disable the fan monitoring function of backplane by DIP
switch (SW1).
D
Signal
I
ndicator
The event LED with red/black wire is located on front bezel of SR107 Plus
series and can be configured through this pin header.
E
Power Fail Mute
Transfer mute signal from a backplane to PSU.
F
Power Fail Alarm
Send alarm signal to PSU.
G
Buzzer
