1.2 Board Overview
1.2.1 Board Introduction
The CP6925 Gigabit Ethernet switch is a 6U/4HP, unmanaged layer 2, Ethernet fabric board
designed for use with CompactPCI PICMG 2.16 packet switching backplane (PSB) systems.
The CP6925 provides 16 channels of Gigabit Ethernet: 14-channels on the backplane and two
channels on a dual RJ45 connector at the front panel. It supports 10, 100, and 1000 Mbit/s data
transfer rates.
The purpose of the CP6925 is to connect up to 14 Gigabit Ethernet nodes on the backplane
using the J3 and J5 connectors. In addition, two Gigabit Ethernet uplink channels are provided
on the J6A/B connectors. Front panel LEDs are available for each channel to indicate activity
and speed.
The major components involved in this process are: the high-performance, 16-port Gigabit
Ethernet switch controller, BMC5396; four quad-channel Gigabit Ethernet transceivers
(BMC5464), and associated Magnetics for each channel.
Power is supplied to the CP6925 is via the CompactPCI connector J1.
1.2.2 Board Specific Information
Major board components of the CP6925 board are:
• a Gigabit Ethernet switch: BMC5396
• four quad-channel Gigabit Ethernet transceivers: BMC5464
• Magnetics
• dual RJ45 connector
• a configuration EEPROM
Other board features are:
• 14 link ports (LP01 to LP14) via fabric slot connectors J3 and J5
• layer 2, unmanaged
• three speed operation: 10/100/1000 Mbit/s
• auto-negotiation
• galvanic de-coupling
1.2.3 System Considerations
Within any given CompactPCI PICMG 2.16 system there may be up to two CP6925 boards
installed (depends on the availability fabric slots, one or two). Only power is supplied by the
CPCI connector J1. No other backplane signals are available on this connector. There is no
link port ’f’ (fabric-to-fabric) interface available.
