2.2 Product Description - Magnum 6KL Managed Edge Switch
Magnum™ 6KL Managed Edge Switches provide configurability in an entry-
level industrial-grade package. The high performance 6KL base unit comes with four
10/100 copper ports (which may be either regular or PoE). Up to 4 100Mb fiber ports or
up to four more 10/100 copper ports or combinations, may also be configured. In
addition, one or two Gb ports may be configured as 10/100/1000 copper or SFP fiber in
any 6KL base unit.
Magnum 6KL comes with the best-of-breed MNS-6K managed networks
software. (MNS-6K-SECURE optional) See the Managed Networks Software (MNS-6K)
datasheet for more information at
http://www.garrettcom.com/techsupport/software/datasheets/mns6kds.pdf
Magnum 6KLs are ideal for building a switched, hardened Ethernet network
infrastructure, connecting edge devices such as PLCs and IEDs with upstream switches
or routers. Designed for use in industrial applications such as factory floors and control
cabinets, industrial video surveillance systems with PoE, power utility substations,
tariffed carrier field facilities, or transportation and oil and gas, the rugged Magnum 6KL
handles stressful workloads (mixes of bursty data traffic and priority streaming traffic) as
well as harsh environmental conditions.
The 6KL metal case serves as a heat sink and a sealed-case design enables the
unit to operate in harsh Industrial grade environments and achieves high EMI noise
immunity. Heavy duty Ethernet Switch jobs are readily accommodated with an extended
temperature rating of -40˚C to 60˚C by the UL Component Parts method, or -40˚C to
85˚C by the IEC 60068 Type-Test method. With options such as several popular DC
power input types, AC power and DIN-Rail mounting, the hardened Magnum 6KL is a
“multi-purpose” Industrial Ethernet Switch.

The 6KL managed switches also provides a PoE option via power –inside PoE
base unit (6KLP-48VDC) on Slot A and allows the users to utilize up to 4-ports of PoE 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 6KL 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 6KL Managed Edge Switches have heavy-duty steel cases and are
readily available with standard Industrial grade 24VDC power. Alternative internal DC
power options are available. Internal AC power and DC power input types may be 12V,
24V, 48V, 125V, 250V and dual source DC input is optional on the 6KL.
Alarm Relay contacts provided on each Magnum 6KL 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
6KL can do its part to prevent any QOS degradation while it is handling Ethernet traffic
through its ports and buffers.
The Magnum 6KL 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 6KL’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.
While other switching technologies (such as "cut-through" or "express")
impose minimal frame latency, they will also permit bad frames to propagate out to the
Ethernet segments connected. The "cut-through" technique permits collision fragment
frames (which are a result of late collisions) to be forwarded which add to the network
traffic. Since there is no way to filter frames with a bad CRC (the entire frame must be
present in order for CRC to be calculated), the result of indiscriminate cut-through
forwarding is greater traffic congestion, especially at peak activity. Since collisions and
bad packets are more likely when traffic is heavy, the result of store-and-forward
operation is that more bandwidth is available for good packets when the traffic load is
greatest.
When the Magnum 6KL 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 6KL 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.

2.5 Applications
Magnum 6KL Edge Switches offer high performance, modularity and
availability. They provide the flexibility of 100Mbps fiber and copper ports as well as
single or dual Gigabit (1000Mb) ports, with industry-standard LAN management
software. Magnum 6KL Switches are easily used in a variety of applications including
client/server computing, secure VLAN- performance upgrades to departmental networks,
and stream traffic for VOIP and audio/video applications. They can also be used in a
much diversified combination of mixed media in Industrial floor applications. The
performance characteristics of the 6KL Switches enable them to inter-connect a series of
subnets (one subnet per 6KL Switch port) in a LAN traffic center. The subnet
connections may be via fiber or twisted pair cabling, 100Mbps or 10 Mbps speed, and
full-or half-duplex.
The mixed-media modular capability is ideal for industrial applications where
existing Ethernet LAN network cabling must be accommodated. The fiber-built-in
media capability is ideal for integrating future-proof fiber cabling into the LAN structure.

Example 1: Magnum 6KL Switch for an Industrial Application
Equipped with lots of useful features including hardened enclosures, a wide
spread of DC power supply options, and extended temperature ratings qualifies the
Magnum 6KL Managed switch for any Industrial factory-floor, traffic control,
transportation system, or power utility application. The several MNS-6K software
operated features qualifies this managed switch to operate and perform securely and
reliably in all critical applications. The addition of S-Ring and the Link-Loss-Learn
software features allow this Managed switch to provide a very secure highly available
redundant network capability in any ring topology network.
The Managed 6KL’s modularity along with the MNS-6K management
software features remarkably handle industrial environments (i.e. where the factory
floors are networked with Ethernet based mixed-media LANs equipped with PLCs,
computers for taking readings and data from Machines, Client/ Server databases, etc. and
sending these important data to the central office data warehouses) very securely and
reliably. The DIN-Rail Mounting options on the Magnum 6KL allow the factory floor’s
industrial user to mount the 6KL securely anywhere on their Network setup.
The option of setting the ports at 10 or 100Mb on copper and 100Mb on fiber
media provide widespread options to the users to mix and match their legacy and
advance network needs. The modularity of the 6KL Managed Edge Switches make them
an attractive choice for use in applications with LAN connections to an organization’s
multiple site offices and factory- floors. The different locations can be easily connected
together with the Fiber ports supported by the Magnum 6KL Switch. A main NT-server
in a secure area protected from earthquake or fire hazards can be connected to the full
duplex Gigabit Fiber port.

Extended temperature ratings and a variety of options for AC/DC power
supplies qualify this managed 6KL switch for use in non-temperature controlled
networks and many other temperature sensitive critical Industrial applications where
above normal room temperatures occur while the network is in operation. Full-duplex
future proof fiber media can easily connect long distance subnets and provide a stable
secure network to all applications. The SNMP management capability of the Magnum
6KL Switch helps create a database of all the network subnets to easily manage the
network.
Example 2: A managed network is needed to provide a redundant ring topology for
maximum redundancy. In a network where any faulty cable, cable disconnection or
power failure can bring the whole thing down, a ring switch can be reconfigured and up
and running in milliseconds. The ring topology of the network consists of high speed
LAN segments supported by 100Mbps full-duplex future-proof fiber media to provide a
secure long distance LAN connection. The entire network is sharing a higher bandwidth
Gigabit-enabled data-mining server for the vital database located in a separate secured
building. The copper ports are required for multiple subnets inside the power plant to
check the status of other Ethernet units. The entire spread network will be manageable to
provide easy, detectable, uninterrupted support through a viewable SNMP monitor.
