4.1.5 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. Shut down your system, unplug the power cords, then remove the controller. Wait for a minute for
the remaining electric current to dissipate.

board (B).
