A
Mini-SAS HD
For connecting to a mainboard or HBA, this Mini-SAS HD 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 or HBA/RAID card to the 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 a 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 Indicator
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
Buzzer will alarm when fan and temperature become abnormal.
