1.3 Board Overview
1.3.1 Board Introduction
The CP930 five Channel Ethernet Switch is a 3U/4HP CPCI Board designed for use in a CPCI
system.
The CP930 itself is equipped with a five channel switch controller (Marvell 88E6063-RCJ).
Network interfacing is accomplished using CAT5 UTP cabling for 10Base-T and 100Base-TX,
and, optionally, for the fiber optical port, a MT-RJ multimode optical cable is recommended. For
copper solutions, all MAC and PHY functions are integrated into the controller chip. Only gal-
vanic isolation is performed externally. For the fiber optic solution, the controller also provides
MAC and PHY functions, except for the optical transceiver interface. This is accomplished us-
ing an external transceiver module for the channel which also includes the connector to the op-
tical link.
Host interfacing is provided by a CPCI connector, to provide power to the board.
1.3.2 Board Specific Information
Specific board components involved in the Ethernet communications and data handling pro-
cess are:
• Front panel connectors (depending on variant):
• Up to five RJ45 connectors
• Up to five Magnetics modules for galvanic isolation (RJ45 front end)
• One Agilent HFBR-5905 Fiber Optic Transceiver (optional)
• with built-in connectors
• 1300 nm InGaAsP LED and photodiode
• Fast Ethernet switch:
• One five port Fast Ethernet switch from Marvell
• Three linear voltage regulators
• Front panel LED’s:
• Two per channel with RJ45 copper front end
• CompactPCI connector (optional)
• one Molex 4 pole

ponent layout.
1.4.1 System Level Interfacing
There are two different possibilities, depending of the variant, to integrate the CP930 into a sys-
tem. In the standard variant the CP930 is available with a J1 CPCI Connector for integration
within a CompactPCI System (Note: this connector delivers only the power supply). The other
possibility, the CP930-FD standalone variant, is available with a 3.5” housing and a power con-
nector (4pol, MOLEX connector) suitable for ATX power supplies.
