For Your Safety
Your new Kontron product was developed and tested carefully to provide all features neces-
sary to ensure its compliance with electrical safety requirements. It was also designed for a
long fault-free life. However, the life expectancy of your product can be drastically reduced by
improper treatment during unpacking and installation. Therefore, in the interest of your own
safety and of the correct operation of your new Kontron product, you are requested to conform
with the following guidelines.
High Voltage Safety Instructions
Special Handling and Unpacking Instructions
Do not handle this product out of its protective enclosure while it is not used for operational pur-
poses unless it is otherwise protected.
Whenever possible, unpack or pack this product only at EOS/ESD safe work stations. Where
a safe work station is not guaranteed, it is important for the user to be electrically discharged
before touching the product with his/her hands or tools. This is most easily done by touching a
metal part of your system housing.
It is particularly important to observe standard anti-static precautions when changing piggy-
backs, ROM devices, jumper settings etc. If the product contains batteries for RTC or memory
back-up, ensure that the board is not placed on conductive surfaces, including anti-static plas-
tics or sponges. They can cause short circuits and damage the batteries or conductive circuits
on the board.
Warning!
All operations on this device must be carried out by sufficiently skilled
personnel only.
Caution, Electric Shock!
Before installing your new Kontron product into a system always
ensure that your mains power is switched off. This applies also to the
installation of piggybacks.
Serious electrical shock hazards can exist during all installation,
repair and maintenance operations with this product. Therefore,
always unplug the power cable and any other cables which provide
external voltages before performing work.
ESD Sensitive Device!
Electronic boards and their components are sensitive to static elec-
tricity. Therefore, care must be taken during all handling operations
and inspections of this product, in order to ensure product integrity at
all times.

perature, or which has had its serial number(s), any other markings or parts thereof altered,
defaced or removed will also be excluded from this warranty.
If the customer’s eligibility for warranty has not been voided, in the event of any claim, he may
return the product at the earliest possible convenience to the original place of purchase, togeth-
er with a copy of the original document of purchase, a full description of the application the
product is used on and a description of the defect. Pack the product in such a way as to ensure
safe transportation (see our safety instructions).
Kontron provides for repair or replacement of any part, assembly or sub-assembly at their own
discretion, or to refund the original cost of purchase, if appropriate. In the event of repair, re-
funding or replacement of any part, the ownership of the removed or replaced parts reverts to

1. Introduction
1.1 System Overview
The CompactPCI board described in this manual operates using the CompactPCI PICMG
specification 2.16, CompactPCI Paket Switching Backplane. For further information regarding
this CompactPCI standard and its use, visit the home page of the PCI Industrial Computer
Manufacturers Group (PICMG).
Many system-relevant CompactPCI features that are specific to Kontron Modular Computers
CompactPCI systems may be found described in the Kontron CompactPCI System Manual.

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.
