Replacing the Host Board
Before replacing the host board to the controller, you must take note of the following considerations:
•
A controller/host board downtime may occur if you replace a host board for an upgrade.
•
The firmware automatically restores the system to its factory settings when adding or replacing a
host board.
To replace the host board:
1.
Remove the controller that contains the host board you want to replace.
NOTE:
See section
4.1.2 Replacing the Controller Module
for details.
2.
Loosen the screw that secure the host board to the controller, push the release lever, then lift to
remove the host board.
