DANGER
Electrical voltage and current from power cables are hazardous. To avoid a shock hazard,
always place electrical equipment on dry, static-free level surfaces. Never turn on any
electrical equipment when there is evidence of fire, water, or structural damage.
c. Place the controller on a dry, static-free level surface.
5. Remove the cover (see “Removing and installing a cover” on page 5-2).
6. If no host port adapter is installed, skip to the next step. Otherwise, release the four captive
thumbscrews that hold the host port adapter to the controller board. Then, remove the host port
adapter by lift it slightly upward to release it from the board connector, and pull it away from the
front of the controller module.
7. If you are replacing a failed host port adapter, skip to the next step. Otherwise, remove the two
screws from the cover plate. Flip the top edge of the cover plate outward to release the alignment
tab and remove the cover plate from the controller.
