Overview

Several items must be removed from the chassis, before the motherboard may be removed. These items fall into two groups: rear-panel elements and chassis elements. Once these items have been removed, you may remove the motherboard.

Concerned parts

Any Event Master series card fits Slot #1 and Slot #2.

Necessary tools

• 1x Phillips Screwdriver #1
• 1x Phillips Screwdriver #2

Rear-panel elements

1. Remove the hex nuts and the toothed washers from both Genlock BNC connectors, and remove the insulating bushing from the Genlock In BNC connector.

   Note: Do not forget to install the insulating bushing on the Genlock In BNC connector during re-installation.

2. Loosen the thumbscrews on the Event Master series card in Slot #1, and remove the card from the slot.

Chassis elements

1. Remove the top cover.

2. Snip the zip ties on the rear USB cable and the DisplayPort connector cable.

   CAUTION: Not snipping the zip ties around the cables to be moved or removed may result in damage to the zip-tie mounts and the surfaces to which they are attached.

3. Disconnect the Slot #1 edge-card ribbon cable first from the motherboard, then from the Slot #1 interposer, and remove the ribbon cable from the chassis.

4. Remove the two screws that fasten the Slot #1 interposer to the floor of the chassis, and remove the interposer from the chassis.

   These are located on the bottom of the chassis near the front and close to the center of the chassis when looking from left to right.

5. Disconnect the Slot #2 edge-card ribbon cable first from the motherboard, then from the Slot #2 interposer, and remove the ribbon cable from the chassis.
6. Disconnect the DC power cable from the motherboard.
7. Disconnect the rear USB Type B connector cable from the rear-panel USB header on the motherboard.
8. Remove the screws above and below the rear-panel USB Type B connector, and remove the connector and its cable from the chassis.

9. Remove the two screws that fasten the RJ45 (Ethernet) mounting plate to the rear panel of the chassis.

   These screws are below and to the left, and above and to the right of the RJ45 mounting plate. Do not remove the screws on the mounting plate itself. The mounting plate should remain attached to the RJ45 connector on the motherboard.

10. Disconnect the DisplayPort cable from the motherboard.
11. Remove the two screws (just above the Genlock connectors) that fasten the DisplayPort cable to the rear panel, and remove the DisplayPort cable from the chassis.
12. Remove the two screws that fasten the Slot #1 card guide to the motherboard, and remove the card guide from the chassis.

13. Unscrew and remove the card-guide standoffs from the chassis.

    These go through slots in the motherboard, but the motherboard cannot be removed without first removing the standoffs.

The chassis elements are shown removed from the chassis in Image 16–19.

The motherboard

1. Remove the 11 screws that fasten the motherboard to the chassis.

2. Lift the front end of the motherboard, and rotate the motherboard up.

   

3. Remove the motherboard from the chassis.

   Note: There is one BNC insulator on the Genlock input connector. Make sure you put this to the side, so you can re-install it when re-installing the motherboard.

How to install the motherboard

To install the motherboard in the EX chassis, follow the steps of the removal procedure in reverse order.

1. Place the motherboard in the chassis.
2. Install the chassis elements.

3. Install the rear-panel elements.

   Note: Do not forget to install the insulating bushing on the Genlock In BNC connector—both internal to the chassis and external—before installing the toothed washers and hex nuts.
