Card Structure and Dimensions
Card Structure
Figure 8-1 shows card appearance.
A card consists of the following components:
Printed circuit board (PCB)
The PCB contains all the functional chips of the card and is the core of the card. The PCB provides indicators and ports on the front panel.
Different cards provide different indicators and ports. For details, see the description of specific cards.
- Front panel, consisting of the captive screws, ejector levers, and plate
- Captive screws: fix the card into the chassis.
- Ejector lever: allows you to insert and remove the card.
- Plate: joins the ejector levers and the PCB.
Card Dimension
Figure 8-2 shows the definitions of width, height, and depth of a card.
The card dimensions are defined as follows:
- Width: the longest distance between the tops of two ejector levers
- Depth: the distance between a plate and the end of PCB
- Height: the height of the front panel
