2.6. Accessing the Controller Board

2.6.1 Overview

WARNING:

The controller board is a very sensitive component and must therefore be handled with extreme care. Before accessing the controller board, please ensure that all anti-static precautions previously stipulated are strictly adhered to.

The controller board is located in the controller box and should only be removed from the controller box if the controller board fails. However, it is necessary to access the controller board in order to install the DIMM module, optional BBU module and the optional daughter board. To access the controller board, remove the top cover of the controller box. Replace the cover after the different components have been correctly installed.

2.6.2Removing and Replacing the Chassis Top Cover

Removing the top cover: The chassis top cover is secured to the chassis with four retention screws (two on each side). To remove the top cover, remove these four retention screws (see Figure 2-1). Once they have been removed, gently lift the top cover up to expose the controller board.

Figure 2-1: Remove the top cover

Replacing the top cover: After the controller board components have been installed, the chassis top cover must be replaced. To do this, make sure the front panel LCD screen is properly positioned. Next, ensure the top cover is correctly oriented. Notice that the two rectangular holes in the top cover are located at the front and must be installed in this way. Once correctly oriented, gently place the top cover on the chassis and re-insert the four previously removed retention screws (two on each side).
