GM3 – Quad Gigabit Ethernet Rear I/O Card
The GM3 is a mezzanine card which is plugged onto CompactPCI® Serial CPU
boards to implement four Ethernet interfaces on the backplane.
The CompactPCI® Serial standard defines up to eight Ethernet interfaces, which
can be connected in a star or in full mesh architecture via the backplane. The GM3
is used to implement four Gigabit Ethernet interfaces, which are led to the
backplane via CompactPCI® Serial connector P6. All four interfaces are controlled
by one Ethernet controller, which supports the IEEE 802.3x standard.
In addition, the GM3 also provides an mSATA SSD slot to provide mass storage to
the host.
The board is screened for operation in the extended temperature range of -40 to
+85°C.

Product Safety
Electrostatic Discharge (ESD)
Computer boards and components contain electrostatic sensitive devices.
Electrostatic discharge (ESD) can damage components. To protect the board and
other components against damage from static electricity, you should follow some
precautions whenever you work on your computer.
• Power down and unplug your computer system when working on the inside.
• Hold components by the edges and try not to touch the IC chips, leads, or
circuitry.
• Use a grounded wrist strap before handling computer components.
• Place components on a grounded antistatic pad or on the bag that came with the
component whenever the components are separated from the system.
• Store the board only in its original ESD-protected packaging. Retain the original
packaging in case you need to return the board to MEN for repair.

RoHS
Since July 1, 2006 all MEN standard products comply with RoHS legislation.
Since January 2005 the SMD and manual soldering processes at MEN have already been completely lead-free.
Between June 2004 and June 30, 2006 MEN’s selected component suppliers have changed delivery to RoHS-
compliant parts. During this period any change and status was traceable through the MEN ERP system and the
boards gradually became RoHS-compliant.
WEEE Application
The WEEE directive does not apply to fixed industrial plants and tools. The compliance is the responsibility of the
company which puts the product on the market, as defined in the directive; components and sub-assemblies are
not subject to product compliance.
In other words: Since MEN does not deliver ready-made products to end users, the WEEE directive is not
applicable for MEN. Users are nevertheless recommended to properly recycle all electronic boards which have
passed their life cycle.
Nevertheless, MEN is registered as a manufacturer in Germany. The registration number can be provided on
request.

1.3 Thermal Considerations
The Ethernet controller of the GM3 has to be connected to the heat sink of the CPU
board. Please ensure that the installation instructions in the user manual of the CPU
board are followed carefully.
Please note that if you do not follow the instructions, warranty on functionality and
reliability of the GM3 may cease. If you have any questions or problems regarding
thermal behavior, please contact MEN.

2.1 Power Supply
The GM3 is supplied with a primary voltage of +3.3V (±10%) via the board-to-
board connector from the CPU board.
2.2 Board-to-Board Connector
The GM3 is connected to the CPU board via a 40-pin board-to-board connector
which leads one PCI Express x1 link and two USB ports for controlling the Ethernet
controller and the mSATA SSD to the GM3.

2.3 Ethernet Interfaces
The four Ethernet interfaces of the GM3 are led to the CompactPCI Serial connector
P6. See Chapter 2.3.1 CompactPCI Serial Interface on page 15.
The Ethernet controller is connected to the CPU board via a PCI Express x1 link
over the board-to-board connector. It is compliant to the IEEE 802.3, 802.3u, and
802.3ab standards. The four Ethernet interfaces reach a performance of about 100
Mbit/s read and/or write when used simultaneously.
The GM3 supports Wake-on-LAN functionality.
The unique MAC address is set at the factory and should not be changed. Any
attempt to change this address may create node or bus contention and thereby render
the board inoperable. The naming of the interfaces may differ depending on the
operating system. The MAC addresses on GM3 are:
ETH 1: 0x 00 C0 3A A4 Bx xx - 0x 00 C0 3A A4 BF FF
ETH 2: 0x 00 C0 3A A4 Cx xx - 0x 00 C0 3A A4 CF FF
ETH 3: 0x 00 C0 3A A4 Dx xx - 0x 00 C0 3A A4 DF FF
ETH 4: 0x 00 C0 3A A4 Ex xx - 0x 00 C0 3A A4 EF FF
where "00 C0 3A" is the MEN vendor code, A4 is the MEN product code. The last
four digits depend on the interface and the serial number of the product. The serial
number is added to the offset, for example for LAN1:
Serial number 0042: 0x xx xx = 0xB000 + 0x002A = 0x B0 2A.(See Chapter 3.2
Finding out the Product’s Article Number, Revision and Serial Number on page 18.)

2.3.1 CompactPCI Serial Interface
A CompactPCI Serial connector P6 is used to realize the rear I/O Ethernet
connection of the GM3. The connector is directly assembled on the GM3 to achieve
more flexibility as the usage of Ethernet does not depend on the system board itself.
Different mezzanine boards can offer a different number of Ethernet connections,
thereby obtaining maximum scalability.
Please contact MEN sales staff for more information on possible mezzanine board
configurations.
The four Ethernet interfaces of the GM3 are led to the first four peripheral slots of a
standard CompactPCI Serial backplane.
