3. Extract the circuit board:
- For tall circuit boards, use the extraction lever on the front of the board and
the extraction ring at the back of the board to lift the circuit board free of the
connectors on the motherboard.
- For short circuit boards, carefully grasp the board and lift upward to free
the circuit board from the motherboard connectors. You might need to
remove an adjacent tall board to get enough room for a safe hold on the
shorter board.
Board Location Guide
This section provides a simple approach you can use to determine proper board
location. It explains the relationship between the motherboard and video router
connectors and provides tables, charts and examples to assist you in installing boards.
Table 1 (page 8) identifies the inputs and outputs of all Profile boards currently
available, as well as the input and output connections on the video router connectors on
the motherboard. Use this information when:
• Adding a new circuit board to your Profile system and you need to select an
installation slot.
• Moving boards to meet requirements for a new board.
Keep in mind that some circuit boards must occupy a specific slot, while you can install
other boards in almost any slot that meets their I/O requirements.
NOTE: If more than one slot appears in a column in Table 1, the slots are listed in
order of preference.
Video Router to Motherboard Relationship
The video router provides and controls video data to twelve connectors on the
motherboard. These video data connectors are aligned with the main motherboard
connectors for slots J5 through J16. Since the Reference Genlock (RefGen) board must
occupy J16 to provide the necessary system clocks, this discussion excludes J16.
When choosing a board slot, the major constraint on a slot is how the board connects
to the video router. Not all boards require the same number of video I/O connections
and not all video data connectors provide the same number of video I/O connections.
Therefore, you must know how many input and output connections the board you want
to install needs, as well as the available slots that meet those requirements.
