Card Structure

Figure 7-1 shows an example of a card.

Figure 7-1 Card

1. Name label

2. Ejector lever

3. Indicator

4. Port

5. Front panel plate

6. Button

7. Printed circuit board (PCB)



A card consists of the following components:

  • PCB

    The PCB contains all the functional chips and is the core of the card. The PCB provides indicators, buttons, and ports on the front panel. PCBs of some cards provide a clock daughter card slot.


Indicators, buttons, and ports on a card vary depending on the card model. Some cards support clock daughter cards, while others do not. For details, see the description of specific cards.

  • Front panel, made of the following parts:
    • Captive screws: fix the card into the chassis.
    • Ejector levers: allow you to insert and remove the card.
    • Plate: connects the ejector levers and PCB to the panel. Some labels are attached on the plate.

Card Dimensions

Figure 7-2 shows how the dimensions (height, width, and depth) of a card are defined.

The card dimensions are defined as follows:

  • Depth: the distance between the outer edge of an ejector lever and the end of the PCB
  • Width: the longest distance between the outer edges of two ejector levers
  • Height: the height of the front panel
