2.2 Product Description - Magnum 6KM Mobile Ethernet Switch
Magnum™ 6KM Mobile Ethernet Switches provide configurability in Heavy
Duty mobile networking applications. The high performance Magnum 6KM base unit
comes with four 10/100 M12 copper ports (either regular or PoE). Up to four 100Mb
fiber ports or up to four more 10/100 M12 copper ports, or combinations, may also be
configured. Two Gigabit ports may also be configured with 10/100/1000 M12 copper
ports or LC-type fiber ports.
M12 military-style port connectors for copper Ethernet ports (instead of RJ45
connectors) make the 6KM distinctive, and withstand the vibration and shock found in
mobile applications. To connect the M12 port cables, simply align the keyed female
connector to the 6KM male connector and twist the threaded lock to secure.
Magnum 6KM comes with the best-of-breed MNS-6K managed networks
software. (MNS-6K-SECURE optional) See the datasheet for more information at
http://www.garrettcom.com/techsupport/software/datasheets/mns6kds.pdf
Magnum 6KMs are ideal for mobile networks such as on passenger railways,
public service and emergency vehicles, shipboard, mining equipment, and military
vehicles. Applications include in-carriage networking of IP-enabled infotainment
systems, security and surveillance systems, and mobile network devices on trains, light
rail and busses, as well as passenger accommodation technology in a variety of mobile
scenarios. The 6KM Mobile Ethernet Switch has the appropriate agency approvals,
including EN50155 and EN50121-4 Railway Applications Standards, IEC61373 for
shock and vibration, NEMA TS-2 for transportation systems outdoors, and DNV
certification for shipboard and other marine applications. Additional certifications
include third-party UL testing for safety, NEBS L3 compliance, and IEC 61850 & IEEE
1613 for power utilities.
The 6KM’s sealed metal case serves as a heat sink, enabling it to operate in the
harshest mobile environments and achieves high EMI noise immunity. The 6KM is
available with optional Conformal Coating for moisture resistance and is rated IP52 for
protection against dust and dirt. The 6KM can be configured with the user’s choice of
power input, including DC at 12V, 24V, 48V, 110V, 125V, 250VDC, and Dual-Source
for each, as well as universal AC.

The 6KM managed switches also provides a PoE option via power –inside PoE
base unit (6KMP-48VDC) on Slot A and allows the users to utilize up to 4-ports of PoE
or 8-ports with additional PoE module (P6KM4-4M12) on Slot C to support 802.3af
Powered devices. See details for PoE base unit in sec 5.1.11. The Power Sourcing
Equipment (PSE) is fully compatible with Powered Devices (PD)(e.g wireless access
points, IP phones) that comply with the IEEE 802.3af PoE standard. The PoE switch
ports have an auto-sensing algorithm, so that they provide power only to 802.3af, PoE
end devices. PoE is managed by a multi-stage handshake to protect equipment from
damage and to manage power budgets . The PoE ports will discontinue supplying
power when the PoE powered devices are disconnected. This feature supports the
802.3af PoE PSE standard for over-current protection, under-current detection, and fault
protection.
High performance features include non-blocking unicast traffic speed on all
ports and 802.1p QoS Traffic Prioritization. Magnum 6KM switches are “plug-and-play”
and are designed for use in connecting edge devices such as PLCs, IEDs and PoE video
cameras with upstream switches and routers where a mix of bursty data traffic and
priority streaming traffic for video surveillance and cell-tower applications are present.
Magnum 6KM Mobile Ethernet Switches have heavy-duty steel cases and are
readily available with standard Industrial grade DC power. Internal AC power and DC
power input types may be 12V, 24V, 48V, 110, 125V, 250V and dual source DC input is
optional on the 6KM.
Alarm Relay contacts provided on each Magnum 6KM Switch monitor the
hardware and software through traps, providing a record of any losses of power signals
and other user- defined software events. See Section 3.5 for details.
2.2.1 Packet Prioritization, 802.1p QOS
Quality of Service means providing consistent predictable data delivery to
users from datagram paths that go all across a network. As a LAN device, the Magnum
6KM can do its part to prevent any QOS degradation while it is handling Ethernet traffic
through its ports and buffers.
The Magnum 6KM switching hardware supports the IEEE 802.1p standard and
fulfills its role in support of QOS, giving packet processing priority to priority tagged
packets according to the 802.1p standard. In addition to hardware support for QOS, the
MNS software (R2) supports two priority queues that can be shared across the eight
levels of defined packet priorities for application-specific priority control by the user
through software configuration settings.
2.2.2 Frame Buffering and Flow Control
Magnum 6KM’s are store-and-forward switches. Each frame (or packet) is
loaded into the Switch’s memory and inspected before forwarding can occur. This
technique ensures that all forwarded frames are of a valid length and have the correct
CRC, i.e., are good packets. This eliminates the propagation of bad packets, enabling all
of the available bandwidth to be used for valid information.

Magnum 6KM Mobile Ethernet Switch Installation and User Guide 07/10
9
www GarrettCom com ..
When the Magnum 6KM Switch detects that its free buffer queue space is low,
the Switch sends industry standard (full-duplex only) PAUSE packets out to the devices
sending it packets to cause “flow control”. This tells the sending devices to temporarily
stop sending traffic, which allows the traffic to catch-up without dropping packets. Then,
normal packet buffering and processing resumes. This flow-control sequence occurs in a
small fraction of a second and is transparent to an observer.
Another feature implemented in the Magnum 6KM Switches is a collision-
based flow-control mechanism (when operating at half-duplex only). When the Switch
detects that its free buffer queue space is low, the Switch prevents more frames from
entering by forcing a collision signal on all receiving half-duplex ports in order to stop
incoming traffic.
2.3 Managed Network Software for Magnum 6KM
Magnum 6KM comes with licensed MNS-6K software or MNS-6K-SECURE, which
allow the user to configure the Magnum 6KM as a Managed Switch and implements
security features and other software enabled features.
(NOTE: Magnum 6KM managed switch will work with MNS-6K Rel v4.1.9
firmware or higher version only, or MNS-6K-SECURE v14.1.9 firmware or higher
version only. Using any earlier MNS-6K versions will not support the 6KM
hardware)

3.0 INSTALLATION
Before installing the equipment, it is necessary to take the
following precautions:
1.) If the equipment is mounted in an enclosed or multiple rack
assembly, the steady-state long-term environmental temperature
around the equipment must be less than or equal to 600C.
2.) If the equipment is mounted in an enclosed or multiple rack
assembly, adequate airflow must be maintained for proper and
safe operation.
3.) If the equipment is mounted in an enclosed or multiple rack
system, placement of the equipment must not overload or load
unevenly the rack system.
4.) If the equipment is mounted in an enclosed or multiple rack
assembly, verify the equipment’s power requirements to prevent
overloading of the building/s electrical circuits.
5.) If the equipment is mounted in an enclosed or multiple rack
assembly verify that the equipment has a reliable and
uncompromised earthing path.
This section describes installation of the Magnum 6KM Switches, as well as connection
of the various Ethernet media types.
3.1 Locating Magnum 6KM Switches
For vertical DIN-Rail mounting, see Section 3.3
For vertical panel mounting and wall mounting, see Section 3.3.1
For DC power input data, see Appendix B. For Dual Source, see Appendix C
.
The rugged metal case of the Magnum 6KM will normally protect it from
accidental damage in a lab or workplace setting. Maintain an open view of the front to
visually monitor the status LEDs. Keep an open area around the unit so that cooling can
occur from convection while the unit is in operation. The 6KM has no fans, so it is silent
when in operation. Internal electronics use the case as a heat sink, so the unit may
normally be quite warm to the touch.

3.2 Connecting Ethernet Media
The Magnum 6KM Switches are specifically designed to support standard
Ethernet media types within a single Switch unit. (See Section 5.1 for a description of
the Modules)
The various media types supported along with the corresponding IEEE 802.3,
802.3D, 802.3u, 802.3AB and 802.3z standards and connector types are as follows:
Media IEEE Standard Connector
Twisted Pair (CAT3 or 5) 10BASE-T M12
Twisted Pair (CAT5) 100BASE-TX M12
Twisted pair (CAT5E or CAT6) 1000BASE-T M12
Fiber (Multi-mode) 10BASE-FL LC
Fiber (Multi-mode) 100BASE-FX LC
Fiber (Single-mode) 100BASE-FX LC
Fiber (Multi-mode) 1000BASE-SX LC
Fiber (Multi-mode, Single-mode) 1000BASE-LX LC
Fiber (Single-mode) 1000BASE-ZX LC
See http://www.garrettcom.com/techsupport/power_budget.pdf for Power budget
calculations, to find fiber cable distance information.
3.2.1 Connecting Twisted Pair for 10/100Mb (CAT3, CAT5, UTP or STP)
The M12 ports of the Magnum 6KM can be connected to the following two
media types: 100BASE-TX and 10BASE-T. CAT 5 cables should be used when making
100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3 may be
used. In either case, the maximum distance for unshielded twisted pair cabling is 100
meters (328 ft).
NOTE : It is recommended that high quality CAT. 5 cable be used whenever possible
in order to provide flexibility in a mixed-speed network, since 10/100 copper
switched ports are auto-sensing for either 10 and 100Mb/s.
The following procedure describes how to connect a 10BASE-T or 100BASE-TX twisted
pair segment to the M12 port. The procedure is the same for both unshielded and
shielded twisted pair cables.
1. Using standard twisted pair cable with M12, 4-pin connector at 6KM side, insert
the end of the cable with an M12 plug into the M12 connector of the port.
(unshielded or shielded cables and wiring may be used)
2. Connect the other end of the cable to the corresponding device
3. Use the LINK/A LED to ensure proper connectivity by noting that the LED will
be illuminated when the unit is powered and proper connection is established.

NOTE: for Power Substations: In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the M12 ports are intended for connectivity
to other communication equipment such as routers or telecommunication
multiplexers installed in close proximity (i.e., less than 2 meters or 6.5ft) to the
6KM. It is not recommended to use these ports in substation applications to
interface to field devices across distances which could produce high (greater than
2500V ) levels of ground potential rise (GPR) during line-to-ground fault
conditions. The 6KM passes the 1613 specifications for zero packet loss with fiber
ports & with M12 ports used as indicated here.
Fig 3.2.1a 10/100Mb 4-Pin D-Coded M12 pin configuration
3.2.2 Connecting Twisted Pair for Gigabit (CAT5e or better, UTP or STP)
The M12 Gigabit ports of the Magnum 6KM can be connected to the media
types, 1000BASE-T or CAT 5E or better 100-ohm UTP or shielded twisted pair (STP)
balanced cable. The CAT 5E or better 100-ohm UTP or shielded twisted pair (STP)
balanced cable is recommended to use when making 1000BASE-TX connections. In
either case, the max distance for unshielded twisted pair cabling is 100 meters (328 ft).
The following procedure describes how to connect a 1000BASE-T twisted pair segment
to the M12 port. The procedure is the same for both unshielded and shielded twisted pair
cables.
1. 1000BASE-T connections require that all four pairs or wires be connected.
Using CAT5e or better twisted pair cable with M12, 8-pin connector at 6KM
side, insert the end of the cable with an M12 plug into the M12 connector of the
port.
(unshielded or shielded cables and wiring may be used)
2. Connect the other end of the cable to the corresponding device
3. Use the LINK LED to ensure proper connectivity by noting that the LED will be
illuminated when the unit is powered and proper connection is established.

Pin 7 = TX+ (MDI0-)
Pair 3 Pin 5 = RX+ (MDI1-)
Pin 8 = RX- (MDI1+)
Pair 4 Pin 2 = RX+ (MDI2-)
Pin 3 = RX- (MDI2+)
Fig 3.2.2a 1000Mb 8-Pin A-Coded M12 pin configuration
3.2.3 Connecting Single-Mode Fiber Optic
When using single-mode fiber cable, be sure to use single-mode fiber port
connectors. Single-mode fiber cable has a smaller diameter than multi-mode fiber cable
(9/125 microns for single-mode, 50/125 or 62.5/125 microns for multi-mode where xx/xx
are the diameters of the core and the core plus the cladding respectively). Single-mode
fiber allows full bandwidth at longer distances, up to 70km with the single-mode LC.
3.2.4 Connecting Fiber Optic Cable to LC ports
1. Before connecting the fiber optic cable, remove the protective dust caps from
the tips of the connectors. Save these dust caps for future use.
2. Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens
tissue dampened in alcohol. Make certain the connectors are clean before
connecting.
3. Connect the Transmit (TX) port on the Magnum 6KM to the Receive (RX) port
of the remote device. Connect the Receive (RX) port on the 6KM to the
Transmit (TX) port of the remote device.
While connecting fiber media to LC connectors, simply snap on the two square
male connectors into the LC female jacks of the Fiber connector until it clicks
and secures.
The LINK LED on the front of the 6KM will illuminate and turn Green, when a proper
connection has been established at both ends (and when power is ON in the unit). If
LINK is not lit or OFF after cable connection, the normal cause is improper cable
polarity. Swap the fiber cables at the 6KM connector and also check the connectivity on
the target device to remedy this situation.
Reconfigure or reboot both of the devices if required.
If connected properly, you can check via (MNS-6K) software for verifying the validity of
SFF Gigabit ports.
