Functional Description
The following chapters present more detailed, board level information about the CP342, the
CP342-SFP, and the CP342-RIO versions of the product whereby the board components and
their basic functionality are discussed in general.
2.1
General Information
The CP342 is designed as a dual channel Gigabit Ethernet CompactPCI IO board with inter-
facing for front panel connectors as well as supporting rear IO on the J2 connector. There are
three versions available with each version supporting a single interfacing type:
• a dual RJ45 connector (CP342)
• two single SFP cages for SFP transceivers (CP342-SFP)
• rear IO interfacing for both Gigabit Ethernet channels (CP342-RIO)
In addition, there are operational status LEDs provided with each version:
• integrated connector LEDs on the dual RJ45 connector
• three LEDs for each SFP/RIO Ethernet channel on the front panel
Further, there is a PLCC32 socket available for installing optional Boot Flash memory.
2.2
Board-Level Interfacing Diagram
The following figure demonstrates the interfacing structure between the internal processing
modules of the CP342 and other major CP342 module components. Where CP342 system el-
ements 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.
Board functions are dependent on the CP342 version and mutually exclusive of each other ex-
cept for the LEDs which are shared by the CP342-SFP and CP342-RIO versions.
