Board Structure

Board Structure

A board mainly consists of the printed circuit board (PCB) and the front panel.

Figure 3-1 shows the structure of a board (using the SCUN board as an example).

Figure 3-1  Board structure

A board mainly consists of the following parts:

  • PCB

    The PCB houses various functional chips of the board and is the most important part of the board. Through the front panel, the PCB provides indicators, buttons, and ports. For some boards, the PCB also provides a position for installing a daughter board.


    Different boards provide different indicators, buttons, and ports; not all boards support a daughter board. For details, see the description of each board.

  • Front panel, including the captive screws, ejector levers, and plate
    • Captive screws: secure the board in the subrack.
    • Ejector levers: used for inserting or removing the board.
    • Plate: connects the PCB and the ejector levers. The plate also provides a surface for attaching some labels (such as the bar code label and laser label).
