Removing and Replacing a SIM Board

This section describes how to remove and replace a SIM board.



caution icon Caution - Potential loss of data access - Never remove a SIM assembly unless the SIM Locate LED is blue. See FIGURE 1.


Caution - The power supplies in this equipment can produce high energy hazards. Only personnel with authorized access to this equipment should remove and replace modules in the system.

procedure icon  To Remove a SIM Board

1. From the back of the disk tray, locate the failed SIM. The SIM Locate LED is blue. (See FIGURE 1.)

2. Label and then disconnect the tray interface cables.

To disconnect the SAS cable use two hands. With one hand grasp the metal body of the connector, with the other hand firmly grasp and pull the tab. Pull the tab gently in toward the connector body and then with the other hand extract the connector from the bulkhead. Do not twist or pull the tab in any direction other than parallel with the connector body or you might break the tab. If the tab were to break, a small sharp object (such as a fine-tipped screwdriver) would be required to lift the metal spring at the top of the connector shell to unlatch it.

3. Loosen the two captive screws using your thumb and forefinger.



Note - If the captive screws are too tight to loosen by hand, use a #2 Phillips screwdriver to loosen each screw.


4. Push each ejector tab outward to release the SIM from the chassis. (See FIGURE 2.)

caution icon Caution - Use care when handling either the new or failed SIM board. Make sure all ESD precautions are being followed.


Caution - For products with multiple power cords, all power cords must be disconnected to completely remove power from the system.
