The following signal denes the sideband connector which can
work with Areca sideband cable on its SFF-8087 to 4 SATA cable.
The sideband header is located at backplane. For SGPIO to
work properly, please connect Areca 8-pin sideband cable to the
sideband header as shown above. See the table for pin denitions.
Step 7. Re-check the SATA HDD LED and Fault LED Cable
Connections
Be sure that the proper failed drive channel information is dis-
played by the fault and HDD activity LEDs. An improper connection
will tell the user to ‘‘Hot Swap’’ the wrong drive. This will remove
the wrong disk (one that is functioning properly) from the control-
ler. This can result in failure and loss of system data.
Step 8. Power up the System
Check the installation thoroughly, reinstall the computer cover, and
reconnect the power cord cables. Turn on the power switch at the
rear of the computer (if equipped) and then press the power button
at the front of the host computer.
