Installing Host Boards
NOTE
As an upgrade to existing Single-Controller systems, down time may occur! Please
install one controller at a time. ALWAYS install to the left host board slot (close to SAS
Exp.) first before installing to the right host board slot! If you want to install a different
host board than currently installed, make sure that you replace both host boards. Both
installed host boards must be identical! The system will do a factory reset!
1. Shutdown (for Single-Controller systems in operation) and remove the controller
from the enclosure.
2. For users installing a new host board, you will need to remove the screws holding
the dummy covers in place.
3. If you are replacing an existing host board, please loosen the thumb screw that is
securing the host board onto the controller and gently lift the host board.

4. By holding onto the edges of the PCB and using the “guide pin” for positioning, power
the replacement host board into the controller. Tighten the thumb screw to complete the
installation. Reinsert the controller back into the system.
