G301 – 3U CompactPCI® Serial Unmanaged 4-Port ETH
Switch
The G301 is an unmanaged 3U Ethernet switch implemented as a CompactPCI®
Serial board. It occupies one peripheral slot, using a 4 HP front panel sporting
4 Gigabit Ethernet ports on RJ45 connectors. Options include M12 front connectors
and a P6 connector for the rear I/O Ethernet signals from the board's fifth Gigabit
Ethernet port.
The G301 supports full-duplex and half-duplex operation with auto-negotiation,
high-speed non-blocking store-and-forward switching, Quality of Service (QoS)
support with four traffic classes IEEE 802.1p and three-level 802.1x security. The
switch is fault tolerant and restores itself on its own: If a link is temporarily
unavailable, frames can be sent via backup/redundant links (spanning tree protocol /
link aggregation) and no data loss occurs. Its built-in test mechanisms make the
G301 an even more reliable component in the communication system.
In addition, the switch can act as Power over Ethernet (PoE) Power Sourcing
Equipment (PSE), supplying other devices on all ports with power.
By using an application-specific configuration EEPROM, the G301 can act
similarly to a managed switch with fixed settings. This enables features untypical
for unmanaged models like 802.1p priority and port based priority, port based
VLAN or IEEE 802.1q VLAN IDs.
The board is specifically designed for rugged mobile communication systems. It is
thus for example fully compliant with the EN 50155 railway standard, screened for
a -40 to +85×C operation temperature and ready for coating.

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 cir-
cuitry.
• 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.

2.3 Ethernet Switch
The G301 uses a 5-port 10/100/1000Base-T switch component, the Marvell
88E6171. The switch provides 10/100/1000 Mbits/s configuration possibility on the
four front Ethernet ports and 1000 Mbits/s on the rear Ethernet port.
It is also possible to configure each port in half-duplex or full-duplex.
The switch characteristics are:
• Four external front ports configurable as 10/100/1000 Mbits/s and one rear port
fixed to 1000 Mbits/s
• GMII digital interface (not supported in standard G301 models)
• Each external port is configurable in half-duplex or full-duplex mode
• Non-blocking wire speed switching
• Store-and-forward mode
• Auto negotiation
• Port mirroring
• Port monitoring
• Flow control
• VLAN support
• Automatic MDI/MDI-X crossover (all ports)
• Port based frame priorization
2.3.1 Configuration of the Switch
The G301 loads the following standard configuration for all ports at startup:
Table 3. Default switch configuration at startup
By using a customer-specific configuration EEPROM, the G301 can act similarly to
a managed switch with fixed settings. Please contact MEN if you need a switch with
a non-standard configuration.
Setting Default
Duplex mode Full Duplex
Port speed Auto-Negotiate
VLAN (port-based) Off
QoS (Quality of Service) Off
Port mirroring and port monitoring Off
Port trunking Off
Power over Ethernet functionality PSE functionality enabled

20G301-00 E4 – 2012-10-04
2.4 Power over Ethernet
All front panel ports of the G301 support Power over Ethernet PSE ("power
sourcing equipment") functionality according to IEEE802.3af.
The G301 can deliver power to up to four PD ("powered device") devices.
Table 4. Power over Ethernet configuration
A combination of different classes is also possible. Please note, however, that the
combined power level drawn by connected PDs must not exceed 28 W!
2.5 Front Panel Status LEDs
The front panel features two LEDs for each of the four Ethernet ports to display
their status (LNK and ACT). The LEDs act as described in the following table.
