Product Description - Magnum 6KQE Managed Edge Switch
Magnum™ 6KQE Managed Edge Switches provide configurability in an entry-
level industrial-grade package. The high performance 6KQE base unit comes with four
10/100 copper ports (which may be either regular or PoE). Up to 3 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 6KQE base unit.
Magnum 6KQE 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
Magnum 6KQEs 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
6KQE handles stressful workloads (mixes of bursty data traffic and priority streaming
traffic) as well as harsh environmental conditions.
Advanced thermal design techniques with ribbed–surface Aluminum cases for
maximum heat dissipation and a sealed case design enables the unit to operate in harsh
Industrial grade environments efficiently. 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 6KQE is a “multi-purpose” Industrial Ethernet Switch.

The 6KQE managed switches also provides a PoE option via power –inside
PoE base unit (6KQEP-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 5.2. 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 6KQE 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 6KQE Managed Edge Switches have heavy-duty aluminum 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 6KQE.
Alarm Relay contacts provided on each Magnum 6KQE 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
6KQE can do its part to prevent any QOS degradation while it is handling Ethernet
traffic through its ports and buffers.
The Magnum 6KQE 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 6KQE’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 6KQE 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 6KQE 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.

Applications
Magnum 6KQE 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 6KQE 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 6KQE Switches enable them to inter-connect a series
of subnets (one subnet per 6KQE 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 6KQE 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 6KQE 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 6KQE’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 6KQE allow the factory floor’s
industrial user to mount the 6KQE 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 6KQE 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 6KQE 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 6KQE switch for use in non-temperature controlled
02/09
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
6KQE 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.
Fig 2.5b Magnum 6KQE equipped with S-Ring in redundant ring solution
The Magnum 6KQE Managed Edge Switch equipped with a mix of copper and
fiber ports provides an economical and seamless solution to many requirements. The
user-configurable Magnum 6KQE provides an extra boost to the network requirements
by providing copper/fiber media along with the higher bandwidth support of 10/100 and
1000Mb. The user can utilize the SNMP feature equipped with VLAN, RMON, STP and

other standard managed LAN features to provide a secure and stable network.
The 6KQE Managed Fiber with S-ring and Link-Loss-Learn features easily
fulfill the redundant requirement with a secure and fast reconfiguration time for cable
breakup when set up in a ring topology. The Gigabit port option boosts the bandwidth for
high speed to support the peak traffic and minimize congestion.
Example 3: In another application in an industrial environment, a 12 port Nebs
compliant, 24VDC managed switch is required to meet the fiber and copper connections
to cover the wider area of video CCTV. The switch must be SNMP enabled and managed
to easily monitor the whole setup.
The Magnum managed edge switch easily qualifies for this requirement with
the various features and modularity it has. Loaded with MNS-6K management software,
the edge switch provides a very effective and economical solution for the video -vignette
environment.
The security features (e.g. port-security, VLANs, SNMPv3, secure telnet, etc.)
also boost the Magnum managed switches to provide a very effective and reliable
solution. The modularity feature to support both copper and fiber at either
10/100/1000Mb speeds easily meets the various speeds of legacy and future broadband
requirements.
In a fast growing secure video environment, the 6KQE is a reliable and secure
solution. The modular design of the Magnum 6KQE, provides a wide range of
copper/fiber options to meet requirements. The Gigabit uplink for storage or broadband
uplink allows the telecom user a very effective solution to store their sensitive data
securely.

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 6KQE Switches, as well as connection
of the various Ethernet media types.
3.1
Locating Magnum 6KQE Switches
For vertical panel mounting and wall mounting, see Section 3.3
For vertical DIN-Rail 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 6KQE 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 6KQE 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.

Connecting Ethernet Media
The Magnum 6KQE Switches are specifically designed to support standard
Ethernet media types within a single Switch unit. This is accomplished by using a two
popular Fiber Connectors which can be individually selected and configured.
(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:

3.2.1
Connecting Twisted Pair (CAT3, CAT5, UTP or STP)
The RJ-45 ports of the Magnum 6KQE 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 RJ-45 port. The procedure is the same for both
unshielded and shielded twisted pair cables.
1. Using standard twisted pair media, insert either end of the cable with an RJ-45
plug into the RJ-45 connector of the port. Note that, even though the connector is
shielded, either 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.

NOTE: for Power Substations: In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the RJ-45 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 6KQE. 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 6KQE passes the
1613specifications for zero packet loss with fiber ports & with RJ-45 ports used as
indicated here.
3.2.2
Connecting Twisted Pair (CAT5e or better, UTP or STP)
The RJ-45 Gigabit ports of the Magnum 6KQE 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 RJ-45 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. Insert
either end of the cable with an RJ-45 plug into the RJ-45 connector of the port.
Note that, even though the connector is shielded, either 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
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, about 70km with the single-mode LC.

Gigabit SFP (Small Form-factor Pluggable) Transceivers
The small form-factor pluggable (SFP) is a compact optical transceiver used in
optical communications for both telecommunication and data communications
applications. Due to its compact, hot pluggable characteristics, SFPs are becoming a very
popular choice for various applications. The small-chassis Magnum 6KQE is designed
for industry-standard Gb-SFPs for user selection of the SFP gigabit media type as
desired.
All SFPs used in Magnum 6KQEs are compliant with the industry standard Multi-Source
Agreement (MSA) ensuring compatibility with a wide range of networking kit.
(see Section 1.2 for the SFP’s available for the 6KQE)
Note: It is highly recommended to remove the fiber cable first before
removing the SFP transceiver for any reason. Not removing the fiber cable
first can damage the fiber cable, cable connector or optical interfaces. It is
advised not to remove and insert a SFP transceiver frequently as this may shorten its
useful life.
Note: Always use an ESD wrist strap while handling the SFP transceivers
since the SFP modules are static sensitive devices.
Note: The copper 1000BASE-T SFP transceiver port supports 1000Mb only. It is
recommended to use a straight-through RJ-45(4-twisted pair) connection while
connecting to any Server/workstation. While connecting with any Switch/repeater or
other device, it is recommended to use Crossover RJ-45 (4-twisted pair) category 5 or
higher cabling. The maximum length supported on copper 1000BASE-T is
100m (328 ft.).
3.2.5
Connecting Fiber Optic Cable to SFP Transceivers
1.
Before connecting the fiber optic cable, remove the protective dust caps from
the tips of the connectors on the PM. 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.
Note: One strand of the duplex fiber optic cable is coded using color bands at regular
intervals; you must use the color-coded strand on the associated ports at each end of the
fiber optic segment.

3.
Find the Transmit (TX) and Receive (RX) markings on the SFP transceiver to
verify the top side of it. Some of the transceiver marks arrow sign for up.
4.
Position the SFP transceiver correctly before insertion, and then insert the SFP
transceiver carefully, until the transceiver connector snap into the place in the
socket connector.
5.
Connect the Transmit (TX) port on the Magnum PM to the Receive (RX) port
of the remote device. Connect the Receive (RX) port on the PM to the
Transmit (TX) port of the remote device.
The LINK LED on the front of the PM 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 PM 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
SFP Gigabit ports.
3.3
Mounting Dimensions for 6KQE with metal brackets
Each Mangum 6KQE is supplied with metal mounting brackets and screws to
mount the unit securely on a panel or wall. It is recommended to mount the 6KQE
vertically, as shown on following page, for proper cooling and long-life reliability. It is
also advisable to mount the unit with space for air movement around the top and the
sides, typically a minimum of 1 inch.
Note:
The metal brackets supplied, hold the back of the 6KQE unit out from the
panel or wall behind it, creating a rear space of about ¼ inch or 1cm. This allows
air circulation and cooling of the rear part of the case.
For best cooling of the 6KQE, attach the metal brackets to metal (rather than wood
or plastic). Attaching to metal helps conduct heat away from the 6KQE through the
metal brackets and into the metal support structure.
Since the 6KQE has special internal thermal techniques (patent pending) to move
the heat generated by the electronic components inside into the case, the case may
be quite warm to the touch during normal operation.

3.3.1
DIN-Rail Mounting the Magnum 6KQE
The Magnum 6KQE is designed for use in a “factory floor” industrial
environment. It is available with an optional DIN-Rail bracket to mount it securely in a
metal factory floor enclosure, maintained
vertically for proper convection cooling of the
unit. The Magnum 6KQE requires one DIN-
Rail bracket for secure mounting. This may
be ordered as Model # DIN-RAIL-6KQ. See a
6KQE viewed from the side, at the rear, with
model DIN-RAIL-6KQ in place on the unit.
The DIN Rail bracket is mounted on
one of three available positions at the rear of
the 6KQE unit. Eight threaded holes are
provided on the rear of 6KQE for DIN-Rail
mounting purposes. The required four screws
are included with the DIN-Rail bracket, and

Position the DIN bracket over the top of the DIN-Rail. Then, snap the bracket into
holding position by moving the bottom of the 6KQE inwards to a vertical position. The
DIN-Rail bracket is heavy duty, and will hold the 6KQE securely in position, even with
cabling attached to the unit.
To release the 6KQE from the DIN-Rail mounting, press the top of the DIN-Rail
bracket slide DOWN to release the 6KQE so that it can be dismounted by pulling the
bottom out. Once the bottom of the 6KQE is rotated out, the DIN-Rail bracket is not
engaged and the 6KQE can be moved up and out, free of the DIN-Rail mounting.
The DIN-Rail mounting bracket is optional and needs to be ordered as separate
items, e.g Model # DIN-RAIL-6KQ
3.4
Powering the Magnum 6KQE Managed Edge Switch
The DC internal power supply supports installation environments where the
DC voltage is from 10 to 300 volts depending on the model selected. The power
consumption will range from about 15 up to 20 watts, depending on the port quantity and
types in the configuration.. When connecting the Ethernet cabling, there is no need to
power down the unit. Individual cable segments can be connected or disconnected
without concern for power-related problems or damage to the unit.

Alarm Contacts for monitoring internal power, and Software
Traps
The Alarm Contacts feature, standard on Magnum 6KQE’s, provides two Form
C Normally Closed (NC) contacts to which the user can attach two sets of status
monitoring wires at the green terminal block. When this option is present, the terminal
block for Alarm Contacts is part of the Power Input panel in the 6KQE case. The DC
power input connection is in the same panel.
The first NC Alarm Contact (top position, switch vertically mounted) is a
“Software Alarm”, operated by user settings in the MNS-6K software. The user can
disable the Software Alarm feature with a software configuration command if desired.
When the Software Alarm is enabled, the Form C Normally Closed (NC) contact is held
close during normal software operation. A user-defined software malfunction, such as an
SNMP Trap or a Software Security violation or an S-Ring Fault, causes the contact to
open and thus triggers an alarm in the user’s monitoring system
The second NC Alarm Contact is held closed when there is power on the main
board inside of the Switch. This provides a “Hardware Alarm” because the NC contacts
will open when internal power is lost, either from an external power down condition or
by the failure of the power supply inside of the Magnum Switch.
Useful info. about Alarm contacts:
1. There are four terminal blocks (1,2,3,4) provided next to the DC power supply
2. The left two pins (1,2) are hardware operated
3. The right two pins (3,4) are software operated
4. These are both NC (normally closed) relays
5. The switch’s software operation needs to be enabled and set to get the Alarm traps. For
detailed information about the Software Alarm and software control of SNMP alarm
traps, please reference the Magnum MNS-6K Software User Manual.
The Alarm Contacts are on the front left area (next to the DC power source) of
the Magnum 6KQE unit and are green in color as shown in the picture.

NOTE for Power Substations: In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the serial (DB-9) console ports are
intended for temporary connectivity to other equipment such as PCs. Since the
console port connection is temporary, it is excluded from IEEE 1613 packet-
loss testing per the 1613 standard-defined test procedure.

OPERATION
This chapter describes the functions and operation of the Magnum 6KQE Switch.
4.1
Switching Functionality
A Magnum 6KQE provides switched connectivity at Ethernet wire-speed
among all of its ports. The Magnum 6KQE supports10/100Mbs for copper media and
100Mb separate traffic domains for fiber ports to maximize bandwidth utilization and
network performance. All ports can communicate to all other ports in a Magnum 6KQE,
but local traffic on a port will not consume any of the bandwidth on any other port.
The Magnum 6KQE units are plug-and-play devices. There is no software
configuring necessary to be done for basic operation at installation or for maintenance.
The only hardware configuration settings are user options for an UP-LINK Switch
(resides inside the unit) on the 6KQE4-RJ-45. There is an optional Half / Full duplex
mode and 10Mbps or 100Mbps selection for the switched ports which must be
configured through MNS software per unit as per the requirement. The internal functions
of both are described below.
Filtering and Forwarding
Each time a packet arrives on one of the switched ports, the decision is taken to
either filter or to forward the packet. Packets whose source and destination addresses are
on the same port segment will be filtered, constraining them to that one port and relieving
the rest of the network from having to process them. A packet whose destination address
is on another port segment will be forwarded to the appropriate port, and will not be sent
to the other ports where it is not needed. Traffic needed for maintaining the un-
interrupted operation of the network (such as occasional multi-cast packets) is forwarded
to all ports.
The Magnum 6KQE Switches operate in the store-and-forward switching
mode, which eliminates bad packets and enables peak performance to be achieved when
there is heavy traffic on the network.
Address Learning
All Magnum 6KQE units have address table capacities of 4K node addresses
suitable for use in larger networks. They are self-learning, so as nodes are added,
removed or moved from one segment to another, the 6KQE Switch automatically keeps
up with node locations.
An address-aging algorithm causes least-used addresses to fall out in favor for
frequently-used addresses. To reset the address buffer, cycle power down-and-up.

Auto-Cross(MDIX) and Auto-negotiation, for RJ-45 ports
The RJ-45 ports independently support auto-cross (MDI or MDIX) in auto-
negotiation mode and will work properly with all the other connected devices with
RJ-45 ports whether they support Auto-negotiation (e.g 10Mb Hub, media converter)
or fixed mode at 10Mb or 100Mb Half/Full Duplex(managed switch) or not. No
cross-over cable is required while using the 6KQE’s copper port to other devices.
Operation is according to the IEEE 802.3u standard.
The Managed 6KQE’s Fast Ethernet copper ports can be set for either fixed 100Mb
speed or for 10/100 F/H N-way auto-negotiation per the IEEE802.3u standard. The
selection is made via MNS software. The factory default setting is for auto-negotiation.
At 10Mb or 100Mb-fixed speed, the user may select half- or full-duplex mode by MNS
Software for each RJ-45 port separately. For detail information See Section 2.3 of this
manual for information to access the “6K-MNS Software user guide”
One frequently-used application for the Managed Magnum 6KQE Switch
copper ports is to connect one of them using a fiber media converter to another Switch in
the network backbone, or to some other remote 100Mb device. In this case, it is
desirable to operate the fiber link at 100Mb speed, and at either half- or full duplex mode
depending on the capabilities of the remote device. Standard commercially available
Fast Ethernet media converters mostly do not support auto-negotiation properly, and
require that the switched port to which they are connected be at the 100Mb fixed speed.
Attachments to a 10/100 auto-negotiation port typically will not work properly. The
6KQE Switch’s RJ-45 ports handle this situation by configuring the ports as per desired
through MNS software port settings and can check the port status of each port after the
change.
When Magnum 6KQE RJ-45 copper ports are set for auto-negotiation and are
connected to another auto-negotiating device, there are 4 different speed and F/H modes
possible depending on what the other device supports. These are: (1) 100Mb full-duplex,
(2) 100Mb half-duplex, (3) 10 Mb full-duplex and (4) 10 Mb half-duplex.
The auto-negotiation logic will attempt to operate in descending order and will normally
arrive at the highest order mode that both devices can support at that time. (Since auto-
negotiation is potentially an externally controlled process, the original “highest order
mode” result can change at any time depending on network changes that may occur). If
the device at the other end is not an auto-negotiating device, the 6KQE’s RJ-45 ports will
try to detect its idle signal to determine 10 or 100 speed, and will default to half-duplex
at that speed per the IEEE standard.
General information -
Auto-negotiation per-port for 802.3u-compliant switches occurs when:
-- the devices at both ends of the cable are capable of operation at either
10Mb or 100Mb speed and/or in full- or half-duplex mode, and can
send/receive auto-negotiation pulses, and . . .

-- the second of the two connected devices is powered up*, i.e., when
LINK is established for a port, or
02/09
-- the LINK is re-established on a port after being lost temporarily.
•
NOTE – Some NIC cards only auto-negotiate when the computer system
that they are in is powered. These are exceptions to the “negotiate at LINK –
enabled” rule above, but may be occasionally encountered.
When operating in 100Mb half-duplex mode, cable distances and hop-counts
may be limited within that collision domain. The Path Delay Value (PDV) bit-times must
account for all devices and cable lengths within that domain. For Magnum 6KQE Fast
Ethernet switched ports operating at 100Mb half-duplex, the bit time delay is 50BT.
4.3
Flow-control, IEEE 802.3x standard
Magnum 6KQE Switches incorporate a flow-control mechanism for Full-
Duplex mode. The purpose of flow-control is to reduce the risk of data loss if a long
burst of activity causes the switch to save frames until its buffer memory is full. This is
most likely to occur when data is moving from a 100Mb port to a 10 Mb port and the
10Mb port is unable to keep up. It can also occur when multiple 100Mb ports are
attempting to transmit to one 100Mb port, and in other protracted heavy traffic situations.
Magnum 6KQE Switches implement the 802.3x flow control (non-blocking) on
Full-Duplex ports, which provides for a “PAUSE” packet to be transmitted to the sender
when the packet buffer is nearly filled and there is danger of lost packets. The
transmitting device is commanded to stop transmitting into the 6KQE Switch port for
sufficient time to let the Switch reduce the buffer space used. When the available free-
buffer queue increases, the Switch will send a “RESUME" packet to tell the transmitter
to start sending the packets. Of course, the transmitting device must also support the
802.3x flow control standard in order to communicate properly during normal operation.
Note: When in Half-Duplex mode, the 6KQE Switch implements a back-pressure
algorithm on 10/100 Mb ports for flow control. That is, the switch prevents frames from
entering the device by forcing a collision indication on the half-duplex ports that are
receiving. This temporary “collision” delay allows the available buffer space to improve
as the switch catches up with the traffic flow.

Power Budget Calculations for 6KQE Modules with Fiber Media
Receiver Sensitivity and Transmitter Power are the parameters necessary to
compute the power budget. To calculate the power budget of different fiber media
installations using Magnum products, the following equations should be used:
OPB (Optical Power Budget) = PT(min) - PR(min)
where PT = Transmitter Output Power, and PR = Receiver Sensitivity
Worst case OPB = OPB - 1dB(for LED aging) - 1dB(for insertion loss)
Worst case distance = {Worst case OPB, in dB} / [Cable Loss, in dB/Km]
where the “Cable Loss” for 62.5/125 and 50/125μm (M.m) is 2.8 dB/km,
and the “Cable Loss” for 100/140 (Multi-mode) is 3.3 dB/km,
and the “Cable Loss” for 9/125 (Single-mode) is 0.5 dB/km
and the “Cable Loss” for 9/125 (Single-mode) is 0.4 dB/km (LX25)
and the “Cable Loss” for 9/125 (Single-mode) is 0.25 dB/km (ZX40)
and the “Cable Loss” for 9/125 (Single-mode) is 0.2 dB/km (ZX70)

Magnum 6KQE Managed Edge Switch Port Modules
This chapter describes each Port Module (PM), including appearance,
functionality, and status displays.
5.1
6KQE Modules
An important feature of the Magnum 6KQE is the use of Port Modules for
flexible mixed-media connectivity to RJ-45 copper and various fiber media. The first
four ports (1,2,3 & 4) of the Magnum 6KQE Switches are fixed RJ-45 copper ports with
dual-speed 10/100Mbps auto-negotiating capability. Additionally the switch can accept
up to two Port Modules to provide the user with up to 6 additional ports (10 total)
providing a wide selection of Ethernet copper and fiber media connections with 10, 100
and 1000Mbps capability and up to 70km.
Note: The 6KQE Port modules are not identical to the port modules used in other
6K products such as the 6K25e and 6K16V. For information about other
6K products, please see the applicable manual. For a list of 6KQE Port
Modules, refer to Section 1.2
Each 6KQE Port Module (PM) is individually described in the following sections.

The 6KQE4-RJ45 4-port Copper module provides four 10/100Mb switched
RJ-45 ports. The 10/100Mb switched ports normally (as a default setting) are
independently N-way auto-negotiating and auto-crossover (MDIX) for operation at 10 or
100Mb speed in full- or half-duplex mode. (i.e., each independently selects a mode and
speed to match the device at the other end of the twisted pair cable).

(for auto-negotiation and MDIX details, see Section 4.2 in the 6KQE User Guide).
On the model 6KQE4-RJ45 module, there are four LEDs for each port, two
integrated into the connector, and two below the connector. The LK (Link) LED
indicates “ready for operation” on that port when lit. The blinking ACT (Activity) LED
indicates receiving Activity on that port when lit. The 10/100 LED indicates operation at
100Mb speed when ON and at 10 Mb speed when OFF (when auto-negotiation is not
disabled). The FDX/HDX LED is ON to indicate full-duplex operation and OFF to
indicate the half-duplex mode. A twisted pair cable must be connected into an RJ-45 port
and the Link (LK) indicator for that port must be ON (indicating there is a powered-up
device at the other end of the cable) in order for a LK LED to provide valid indications
of operating conditions on that port.
Using the 6K (MNS-6K or MNS-6K-SECURE) management software, the
user may disable auto-negotiation and fix the desired operation of each RJ-45 port. The
user may select 10Mb or 100Mb speed and full- or half-duplex mode per-port as per user
requirements. (See Magnum MNS-6K Software Manual for additional info)
NOTE: for Power Substations: In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the RJ-45 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 6KQE. 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 6KQE passes the
1613specifications for zero packet loss with fiber ports and with RJ-45 ports
used as indicated here.
5.1.4
6KQE4-1MMRJ, 1 x MTRJ / 3 x RJ45 (Slot C)
The 6KQE4-1MMRJ 4-port Fiber / Copper module provides one 100Mb
Multimode MTRJ Fiber port and three 10/100Mb switched RJ-45 ports.
The 6KQE4-1MMRJ fiber port is a Small Form Factor (SFF) MTRJ
Multimode connector. The MTRJ’s small size and ease of connection make it a good
choice for 100Mbps “fiber-to-the-desktop” Ethernet connectivity. When installed in a
Magnum 6KQE Series Switch, it supports fiber optic cable distances up to the IEEE-

standard 100Mbps distance limits, i.e., typically 2km at full-duplex and 412m at half-
duplex.
Each port has an Activity (ACT) LED indicating packets being received and a
Link (LK) LED that indicates proper connectivity with the remote device when lit.
The 6KQE4-1MMRJ copper ports support Ethernet twisted pair segments of
any standard length. It is equipped with a three-port RJ-45 connector, and offers 10/100
full / half-duplex auto-negotiating capability on each port. The RJ-45 connector is
shielded to minimize emissions and will allow both unshielded twisted pair (UTP) and
shielded twisted pair (STP) cable connections. When installed in a Magnum 6KQE Series
Managed Switch, the copper ports support the standard distance of 100m on each port.

6KQE4-1MLC, 1 x LC / 3 x RJ45 (Slot C)
The 6KQE4-1MLC 4-port Fiber / Copper module provides one 100Mb
Multimode LC Fiber port and three 10/100Mb switched RJ-45 ports.
The 6KQE4-1MLC fiber port is a Small Form Factor (SFF) LC Multimode
connector used primarily in 100Mbps fiber-to-the-desktop links. When installed in a
Magnum 6KQE Series Switch, it supports fiber optic cable distances up to the IEEE-
standard 100Mbps distance limits, i.e., typically 2km at full-duplex and 412m at half-
duplex.
The compact size of the LC Connector reduces the size of wiring panels in
wiring closets while providing the advantage of “future-proof” fiber optic technology.
The cable end is a “plug-in” connector with both fiber strands terminated in
one housing that cannot be improperly inserted. Each port has an Activity (ACT) LED
indicating packets being received and a Link (LK) LED indicating proper connectivity
with the remote device when lit.
The 6KQE4-1MLC copper ports support Ethernet twisted pair segments of any
standard length. It is equipped with a three-port RJ-45 connector, and offers 10/100 full /

6KQEP-48VDC, Base Unit w/PoE Power-pass-through
The 6KQE is available with the option of having PoE capabilities on the four
fixed RJ45 ports in the base unit (ports 1, 2, 3 and 4).
The PoE (Power-over-Ethernet) RJ-45 ports are similar to regular RJ-45 ports,
except they have the capability of providing power on each port to power up attached PD
devices, per the IEEE802.3af PoE standard. The power-pass-through PoE ports are
dependent upon the -48VDC input power to supply the PD power for these RJ-45
(10/100) ports. Each port supplies up to 15watts to power attached PoE PD devices.
The LEDs on the PoE ports are slightly different compared to regular (non-
PoE) RJ-45 ports. When the PoE port is in use, the PoE LED is ON when connected
properly to an IEEE 803.af compliant PD device on that port. When non-PoE devices are
connected, the PoE LED is OFF. Operation of Ethernet data traffic is not affected by
PoE. LINK and ACTIVITY LEDS are combined on the PoE modules into one LED that
is marked as LINK/ACT.
PoE LEDs Summary
•
For PoE devices, each RJ-45 PoE port supports only 802.3af complaint
devices. The PoE LED is ON when the attached PD is drawing power from the
port. The power is supplied on the data pairs, per IEEE802.3af PoE standard.
For non-PoE devices connected, the PoE port will act as a normal RJ-45 port
and the PoE LED is OFF. No power is sent out from the port.
The PoE ports in Magnum 6K’s with 48VDC power input act as a pass-
through, so the 48VDC power input source to the Magnum 6KQE must be
strong enough to provide power to the 6K switch and to all 4-RJ-45 ports with
PD devices connected (up to 15 watts per PoE port).

In the case where the 48VDC power in not internally connected to the POE
port pins and no power is coming to the PoE ports for some reason, all the PoE
port LEDs are ON simultaneously to indicate a trouble condition. The ports

The 12, 24, -48VDC,
125 and 250VDC power options
are designed using diodes inside
on each DC power input line
behind the two external power
connection terminals, so that the
power from an external source can
only flow into the hub. This
allows the Switch to operate only whenever DC power is correctly applied to the two
inputs. It protects the Switch from incorrect DC input connections. An incorrect polarity

APPLICATIONS FOR DC POWERED ETHERNET SWITCHES
Magnum 6KQE Switches are easily installed in a variety of applications where
12, 24, -48VDC, 125 and 250VDC power is used as the primary power source. The DC
power configuration capability provides an Ethernet networking solution utilizing a
special power supply in switches with a proven track record.
The –48VDC solution is particularly useful in the telecommunication industry,
where it is common for facilities to operate on -48VDC power. Such companies include
regular and wireless telephone service providers, Internet Service Providers (ISPs) and
other communication companies. In addition, many high availability equipment services,
such as broadcasters, publishers, newspaper operations, brokerage firms and other
facilities often use a battery backup system to maintain operations in the event of a power
failure. It is also frequently used for computer system backup, management and
operations monitoring equipment.
The 24V and 125VDC options are particularly useful in the industrial
environment, where it is common for facilities to operate on 24VDC or 125VDC power.
The 125VDC options are mainly used in power utilities, such as electrical substations,
electrical generating plants, etc. The 24VDC applications are mainly in heavy duty
industrial automation such as factory floor, process plants, HVAC, military equipment,
etc.

6KQE, 12, 24, –48, 125 and 250VDC INSTALLATION
This section describes the proper connection of the 12, 24, –48, 125 and
250VDC leads to the DC power terminal block on the Magnum 6KQE Switch. The DC
terminal block on the Magnum 6KQE Managed Switch is located on the left front of the
unit and is equipped with four (4) screw-down lead posts. The power terminals are
identified as positive (+) and negative (-), and they are electrically floating inside the unit
so that either may be grounded by the user if desired. The chassis is “earth” or ground
(GND).
The connection procedure is straightforward. Simply insert the DC leads to the
Switch’s power terminals, positive (+) and negative (-) screws. The use of Ground
(GND) connects to the Switch chassis screw provided under the DC terminal. Ensure that
each lead is securely tightened.
NOTE: Always use a voltmeter to measure the voltage of the incoming power supply
and figure out the +ve potential lead or -ve potential lead. The more +ve potential lead
will connect to the post labeled “+ve” and the rest to the “-ve”. The GND can be
hooked up at the last

When power is applied, the green PWR LED will illuminate.
Note: The GND should be hooked up first. The 6KQE unit has a floating ground, so
the user may elect to Ground either + or - terminal to suit the customer’s use.
Before connecting live power lines to the Terminal Block of –48VDC,
12VDC, 24VDC, 125VD or 250VDC products, always use a digital voltmeter to
measure the output voltage of the power supply and determine the lead which is more
“+ve potential”. The more “+ve” voltage lead from 48V or –48V supply must be
connected to the post labeled “+”.

C3.0 DUAL-SOURCE OPTION, THEORY OF OPERATION
The Dual-Source DC power option is designed using diodes inside of the
02/09
chassis on each DC power input line. A diode is placed in each of the four input lines
(behind the four external power
connection terminals) so that
power from an external source can
only flow into the unit. This
allows the unit to operate
whenever DC power is correctly
applied to either or both of the two
inputs.
C4.0
FEATURES AND BENEFITS OF THE DUAL-SOURCE DESIGN
a) The Switch unit can receive power from either input, “A” or “B”. The hub will
normally draw its power from the DC source with the highest voltage at a given
time.
b) The Switch unit will not allow power to flow from a higher voltage input to a lower
voltage input, i.e. the two DC power sources are not mixed together by the hub.
c) When one correct DC input is present, the Switch will receive power if the other DC
input is absent, or even if it is connected with reverse polarity or shorted or
grounded.
d) Reverse polarity connections, if they should accidentally occur on either input, will
not damage the Switch or power supply internally (nor will it blow the fuse in the
internal power supply) because of the blocking action of the diodes. This is true
even if one input connection is reversed while the Switch is operating from the other
source.
e) The Switch will not receive power (and will not work) when both inputs are
simultaneously absent or are both incorrectly connected.

The terminal block is located on the left front of the unit next to the Alarm
terminal block and is equipped with four (4) screw-down lead posts. The primary
terminals are identified as positive (A+),
negative (A-), and the secondary power terminals as negative (B-), positive (B+). The
chassis is earth/ground (GND). The Dual Source terminal block for the 12, 24, 48, 125
and 250VDC are the same.
Note: The GND should be hooked up first. The 6KQE unit has a floating
ground, so the user may elect to Ground either + or - terminal to suit the
customer’s use. Before connecting live power lines to the terminal block,
always use a digital voltmeter to measure the output voltage of the power
supply and determine the lead which is more “+ve potential”. The more
“+ve” voltage lead from a +ve or –ve power supply must be connected to the
post labeled “+”.
The connection procedure is straightforward. Simply connect the DC leads to
the Switch’s power terminals, positive (+) and negative (-) screws. The use of Ground
(GND) is optional; it connects to the Switch chassis. Ensure that each lead is securely
tightened.
