Functional Description
The following chapters present more detailed, board level information about the CP6925
whereby the board components and their basic functionality are discussed in general.
2.1
General Information
The CP6925 is designed as a 16 channel Gigabit Ethernet Switch board with interfacing for
front panel connectors as well as supporting fabric interfacing on the J3 and J5 backplane con-
nectors. In addition, there are two operational status LEDs provided each channel on the board
front panel.

Board-Level Interfacing Diagram
The following figure demonstrates the interfacing structure between the internal processing
modules of the CP6925 and other major CP6925 module components. Where CP6925 system
elements have common interfacing they are grouped into a block. Interfacing common to only
one element of a block is indicated with a direct connecting line. The interfacing lines are shown
in white where they are on board and in black for board external interfacing.
