Accusys 76500/76510
The settings for the master / slave are described in Chapter 3. (only for ACS-76500)
The IDE/SATA cable is the route used for reading and writing to the array.
The power connector supplies power to the RAID box. In order to provide stable power, we
recommend to connect both power connectors on the RAID box.
The 3-pin RS-232 cable is used for remote monitoring of ACS-76500/76510. The RS-232
port is configured with DTE and PC compatible pin assignments.
There is a triangular symbol "▲" on both PCB connector and RS-232 cable connector,
please make sure you connect in the right direction (both triangle symbols match each
other). Connecting in wrong direction will not damage RAID controller, however the terminal
or GUI will not work.
The cooling fan inside the RAID box provides air circulation for the disk drives.
