1.2Other Sources of Information
For further information, refer to the Intel® NetStructure™ MPRTM4808 Rear Transition Board
User’s Manual, Order number 301070.
This section provides safety precautions to follow when installing, operating, and maintaining the
®
NetStructure™ MPRTM4808 Rear Transition Board.
Intel
Intel intends to provide all necessary information to install and handle the Intel MPRTM4808
board in this Installation Guide. However, as the product is complex and its usage manifold, Intel
does not guarantee that the given information is complete. For additional information, contact your
Intel representative.
The Intel MPRTM4808 board has been designed to meet standard industrial safety requirements. It
must be used only in the area of office telecommunication and industrial control.
Only personnel trained by Intel or persons qualified in electronics or electrical engineering are
authorized to install, maintain, and operate the Intel MPRTM4808 board. The information given in
this manual is meant to complete the knowledge of a specialist and must not be taken as
replacement for qualified personnel.
2.1Electromagnetic Compatibility (EMC)
The Intel MPRTM4808 board has been tested in a standard system and found to comply with the
limits for a Class A digital device in this system, pursuant to part 15 of the FCC Rules respectively
EN 55022 Class A. These limits are designed to provide reasonable protection against harmful
interference when the system is operated in a commercial, business or industrial environment.
The board generates and uses radio frequency energy and, if not installed properly and used in
accordance with this Installation Guide, may cause harmful interference to radio communications.
Operating the system in a residential area is likely to cause harmful interference, in which case the
user will be required to correct the interference at his own expense.
If boards are integrated into open systems, always cover empty slots.
2.2Switch Settings
The board provides two onboard switches and one FP reset switch. The switches must be set to
OFF upon initial installation of the board. Refer to Section 3.4, “Switch Settings” on page 17 for
additional configurations.
Electrostatic discharge and incorrect board installation and removal can damage circuits or shorten
their life. Therefore:
• Make sure that you are working in an ESD-safe environment before touching boards or
electronic components.
• When plugging in or removing the board, do not press or pull on the front panel; use the
handles.
• Before installing or removing an additional device or module, read the device’s
documentation.
• Make sure that the board is connected to the CompactPCI backplane via all assembled
connectors and that power is available on all power pins.
• Only install and use the rear transition module with CPU boards especially designed for it.
Otherwise, both the CPU board and the rear transition module may be damaged.
• Make sure to use only the backplane’s rear slot position.
2.4Operation
When operating the Intel MPRTM4808 board in areas of electromagnetic radiation, ensure that the
board is bolted on the CompactPCI system and the system is shielded by enclosure.
Make sure that the board’s contacts and cables cannot be touched while the board is operating.
Do not operate the board outside the specified environmental limits. High humidity and
condensation may cause short circuits. Make sure the product is completely dry and there is no
moisture on any surface before applying power. Do not operate the product below 0°C.
2.5Replacement/Expansion
Only replace or expand components or system parts with those recommended by Intel. Otherwise,
you are fully responsible for the impact on EMC or any possible malfunction of the product.
Check the total power consumption of all components installed and ensure that any individual
output current of any source stays within its acceptable limits. (See the technical specification of
the respective source.)
If more than two IDE devices are connected to the IDE bus, the bus is not able to recognize all of
the devices and the Intel MPRTM4808 board might not start correctly. Therefore, only connect up
to two devices to the secondary EIDE interface on the RTB.
If the secondary EIDE interface on the Intel MPRTM4808 board is connected to an external device,
data may get lost. Therefore, always save data on disk before installing or removing the baseboard
under hot-swap conditions.
The Intel MPRTM4808 board provides several RJ-45 connectors that commonly serve as different
interfaces (RS-485, twisted-pair Ethernet, and telephone). Connecting different interfaces (e.g.,
Ethernet and RS-485) may damage the board. Therefore, make sure that you only connect
matching interfaces. Furthermore, take note of the following:
• Clearly mark TPE connectors near your working area as network connectors.
• Connect TPE bushing of the system to safety extra low voltage (SELV) circuits only.
• Make sure that the electric cable connected to a TPE bushing does not exceed 100 meters.
2.7Environment
Always dispose of used batteries and/or old boards according to your country's legislation and in an
environmentally acceptable way.
The Intel® NetStructure™ MPRTM4808 Rear Transition Board provides easy access to I/O signals
of boards via the CompactPCI backplane.
Backplane I/O signals are available at connector J5. To connect System Management Bus 1 and the
Chassis Management Bus to the board, the Intel MPRTM4808 board provides the Intelligent
Platform Management Bus 1 (IPMB1) and Intelligent Chassis Management Bus (ICMB)
connectors.

• Installation Guide
If delivered as part of a system design, the Intel MPRTM4808 board is already installed in the
system. For information on system connectors available for user-defined system configuration,
refer to the respective system’s guide. The cabling of all other connectors of the Intel MPRTM4808
board must remain as configured at system delivery.
