10/100/1000 copper ports may be configured to a maximum or 12 at 10/100 and 2 Gig
ports. Magnum 6KQ comes with the best-of-breed MNS-6K managed networks software
featuring GUI ease of use, Secure Web Management, SNMPv2,v3 management, 802.1p
QoS Prioritization, Tag-based VLANs, IGMP Snooping and IGMP-L2 multicast
management, port security, RADIUS and TACACS+ support, and a choice of
redundancy options including RSTP and GarrettCom’s rapid-ring-recovery S-Ring and
RS-Ring products. See the Managed Networks Software (MNS-6K) datasheet for more
information.
Magnum 6KQs 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 6KQ
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 -50˚C to 85˚C by the IEC 60068 Type-Test method. With
options such as several popular DC power input types (optional AC power) and DIN-Rail
mounting, the hardened Magnum 6KQ is a “multi-purpose” Industrial Ethernet Switch.

..
The 6KQ managed switches also provide PoE options via power –
inside PoE modules on one of A, B or C slots and allows the users to select a wide option
of combo PoE modules to support 802.3af pd devices. See details for PoE modules in sec
5.2.10. 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 6KQ 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 6KQ Field Switches are provided with LAN management software
including SNMP, Tag- and Port-based VLANs, IGMP-L2 and IGMP Snooping, and Port
Security with control via GUI and command line interface (CLI). For high availability
LANs using ring topologies, Spanning Tree Protocol, RSTP, Link-Loss-Learn and S-
Ring are available. Dual-Homing is a software configuration feature. See the Managed
Networks Software (MNS-6K) and S-Ring datasheets for additional details on the
comprehensive set of software programs and options.
Magnum 6KQ Managed Field Switches have heavy-duty aluminum
cases and are readily available with standard Industrial grade 24VDC power. Alternative
internal DC power options are available. DC power input types may be 24V, 48V, 125V,
and dual source DC input is optional on all 6KQ’s. (AC power is available via an
external power supply unit, see Section 3.4 for details).

Alarm Relay contacts provided on each Magnum 6KQ 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.
The wide selections of Quad port (queen size) modules are key to the flexibility and
adaptability of Magnum 6KQs. Some of the popular 4 ports modules are described
below. For a list of all the modules and options, see Section 1.2
NOTE: The 6KQ modules can only be configured at the factory.
2.2.1 Four-port SFF fiber modules (6KQ4-MTRJ, 6KQ4-MLC), 100Mb
fiber
Fig.2.2.1 :
SFF Fiber Port Modules,
6KQ4-MTRJ (to right) and
6KQ4MLC or -SLC (below)
In a four-port SFF (Small Form Factor) fiber
port module, all of the fiber ports are of the
same speed (100Mb), mode, and connector
type. Small Form Factor (SFF) Fiber Ports
come in multi-mode forms MT-RJ or LC-type connectors, and single-mode form LC-
type connectors.
The 100Mb fiber four-port modules for the Magnum 6KQ’s normally are set
(factory default) to operate in full-duplex mode for best fiber distance and performance.
Using the 6K-MNS software, the user may select full- or half-duplex mode per-port
through set port command.
The set-up of the software
(See Magnum 6K-MNS
Software Manual) gives the
user flexibility to adapt to any
FDX or HDX type of Fast Ethernet devices).
There are three LED’s per fiber port. The Link (LK) LED indicates “ready for
operation” on that port when lit. The F/H LED indicates operation in full-duplex mode
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)

..
when ON (half-duplex when OFF). The blinking ACT LED indicates receiving Activity
on the port. A fiber cable must be connected into a SFF 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.
2.2.2 Four-Port Copper Module, 6KQ4-RJ45
The 6KQ’s 4-port Copper module, model 6K4-RJ45, 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).
(See Section 4.3 for auto-negotiation and MDIX details).
On the model 6KQ-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 6KQ (MNS-6K) 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 details info.).
2.2.3 PoE (power pass-through), model P6KQ4-RJ45 (MDIX), 10/100Mb 4-port
The PoE (Power-over-Ethernet) RJ-45 ports are similar to regular RJ-45 ports,
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)
11
www GarrettCom com
..
except they have the capability of providing power on each port to power up the PD
devices, per the IEEE802.3af PoE standard. The power-pass-through PoE modules 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 the PoE PD devices. A
maximum of 8 PoE ports can be configured in the A and B slots of a 6KQ switch with -
48vdc power input. The PoE modules are also available with mix–n-match fiber modules
configured in other 6KQ slots. Please check the Configuration Guide and the ordering
information Sec.1.2 for all the various P6K PoE module options.
The LEDs on P6KQ4-RJ45- PoE modules are slightly different compared to regular
(non-PoE) RJ-45
modules as shown in Fig
2. When the PoE port is
in use, the PoE LED is
ON when connected
properly to an 803.af
compliant PD device on that port. When non-PoE devices are connected, the PoE LED is
OFF. The 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, as shown in the diagram.
2.2.4 Two-Port Fiber Modules, 2@ 100Mb fiber
The two-port modules are available as two 100Mb fiber ports. ST or SC connector
styles are available utilizing multi-mode or single-mode fiber optics. These fiber
modules may be factory configured with a choice of them in slot B and D only.
The fiber port’s LEDs indicate status the same as the SFF fiber modules in Section 2.2.2
above. Color-coding on the panel of the module shows which LEDs belong to which
port.

..
2.2.5 Two -Port 10 Mb mm Fiber ST Modules
The 2-port @10Mb ST fiber modules behave the same as the 2@100Mb ST
fiber modules except for the 10Mb speed.
The default setup on the 10Mb fiber module is half-duplex, which allows the Magnum
6KQ Switch to connect to any 10Mb hub or media converter or almost any other device
with a 10Mb fiber Ethernet port. The default setting of the 100Mb fiber module is full
duplex. User mode-control per port through the MNS “port settings”
software is the
same as the other 6KQ modules.
The fiber ports support fiber cabling distances according to the 10BASE-FL
and 100BASE-FX standards, i.e., 2km distance for multi-mode fiber. (Single-mode for
greater distances may be available as a special order, request quote).
2.2.6 SFP Gigabit (1000Mbps) port modules
The Gigabit port options for the modular slot come in a few different
configurations of Fiber SFP’s or RJ-45’s. The Magnum 6KQ offers only SFPs (Small
Form Pluggable) for Gigabit speed. There are multiple choices of SFP Gigabit
transceiver types to combine with RJ-45’s for the modular slot. Up to two Gigabit ports
(max.) can be configured in the modular slot D only. An example of a two Gb module is
the 6KQ-2GSFP (SFP fiber). An example of a single Gigabit module is the 6KQ-1GCU
(10/100/1000Mb RJ-45 ports). A combo option of Gigabit copper and SFP fiber (6KQ-
2GSFPCU) is shown below in the figure.
1@ 10/100/1000Mb RJ-45 + 1@ 1000Mb SFP
The 6KQ Modules provide an SFP opening for insertion of industry-standard
SFP transceivers to provide Gigabit (Gb) media flexibility. Gigabit SFP modules are
available in both multi-mode (550m) and single-mode (10, 25, 40, 70) km fiber options
as well as a Gigabit copper option.
There are three LEDs mounted on each Gigabit port module. The Gigabit fiber has LEDs
that indicate F/H (Full/Half duplex), LK (Link status) and ACT (receiving activity) on
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)

..
that port when lit. The copper Gigabit ports come with speeds indicating
(10/100/1000Mb) LEDs also.
The operation of the Gigabit SFP and 10/100/1000 RJ-45 ports is as described
for those port types above. For detailed information about 10Mb mm ST fiber half of the
module, see Section 2.2.5.
2.2.7 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
6KQ can do its part to prevent any QOS degradation while it is handling Ethernet traffic
through its ports and buffers.
The Magnum 6KQ 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.
2.2.8 Frame Buffering and Flow Control
Magnum 6KQ’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 6KQ Switch detects that its free buffer queue space is low,
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)
14
www GarrettCom com
..
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 6KQ 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.
2.2.9 Managed Network Software (MNS-6K ) for Magnum 6KQ-Series
Magnum 6KQ’s come with Rel3.6 licensed MNS-6K software, which allows the user to
configure the Magnum 6KQ as a Managed Switch and implements security features and
other software enabled features.
(NOTE: Magnum 6KQ managed switch will work with Rel 3.6 firmware
or higher version only, using any other MNS-6K version will not support the
hardware)

2.4 Applications
Magnum 6KQ Field 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 6KQ 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
very diversified combination of mixed media in Industrial floor applications. The
performance characteristics of the 6KQ Switches enable them to inter-connect a series of
subnets (one subnet per 6KQ 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 6KQ Switch for a 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 6KQ 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 6KQ’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 6KQ allow the factory floor’s
industrial user to mount the 6KQ securely anywhere on their Network setup.
The option of setting the ports at 10 or 100Mb on copper and 10 or 100Mb on
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)

..
fiber media provide widespread options to the users to mix and match their legacy and
advance network needs. The modularity of the 6KQ Managed Field 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 6KQ 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 6KQ 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
6KQ 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.
The Magnum 6KQ Managed Field Switch equipped with a mix of copper and
fiber ports provides an economical and seamless solution to many requirements. The
user-configurable Magnum 6KQ 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 6KQ 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 field switch easily qualifies for this requirement with the various
features and modularity it has. Loaded with MNS-6K management software, the field
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 6KQ is a reliable and secure
solution. The modular design of the Magnum 6KQs, provide 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.

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 60
0
C.
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 6KQ Switches, as well as connection of the
various Ethernet media types.
3.1 Locating Magnum 6KQ Switches

For DC power input data, see Appendix B. For Dual Source, see Appendix C
.
The rugged metal case of the Magnum 6KQ 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 6KQ 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 6KQ Switches are specifically designed to support all standard
Ethernet media types within a single Switch unit. This is accomplished by using a family
of different Fiber Connectors which can be individually selected and configured per-slot.
See Section 2.2 for a description of the PMs.
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 Fiber Optic ST-type, “twist-lock”
The following procedure applies to installations using a PM with ST-type fiber
connectors. This procedure applies to ports using a 6KQ module, MST-type port.
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. Connect the Transmit (TX) port (light colored post) on the Magnum PM to the
Receive (RX) port of the remote device. Begin with the color-coded strand of
the cable for this first TX-to-RX connection.
4. Connect the Receive (RX) port (dark colored post on the PM) to the Transmit
(TX) port of the remote device. Use the non-color coded fiber strand for this.
The LINK LED on the front of the PM will illuminate when a proper connection has
been established at both ends (and when power is ON in the unit). If LINK is not lit after
cable connection, the normal cause is improper cable polarity. Swap the fiber cables at
the PM connector to remedy this situation.
3.2.2 Connecting Fiber Optic SC-type
, "Snap-In"
The following procedure applies to installations using a PM with SC-type fiber
connectors, i.e., using 6Kq-MSC, 6KQ-SSC single-mode.
When connecting fiber media to SC connectors, simply snap on the two square male
connectors into the SC female jacks of the 6KPM, until it clicks and secures.
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, and may be used to connect 10 Mb nodes
up to 10 Km apart, or 18Km with the 6K-SSC.
The same procedures as for multi-mode fiber, applies to single-mode fiber
connectors. Follow the steps listed in Section 3.2.2 above.
3.2.4 Connecting Twisted Pair (CAT3, CAT5, Unshielded or Shielded)
The RJ-45 ports of the Magnum 6KQ 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 100BASETX 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 6KQ. It is not recommended to use these ports in
substation applications to interface to field devices across distances which
could produce kigh (greater than 2500V ) levels of ground potential rise (GPR)
during line-to-ground fault conditions. The 6KQ passes the 1613specifications
for zero packet loss with fiber ports & with RJ-45 ports used as indicated here.
3.2.5 Connecting Twisted Pair (CAT5e or better, Unshielded or Shielded)
The RJ-45 Gigabit ports of the Magnum 6KQ 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).

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

3.2.6 Gigabit SFP (Small Form-factor Pluggable) Optical 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 6KQ is designed for industry-
standard Gb-SFPs and Gb-SFPCU (copper) for user selection of the SFP gigabit media
type as desired.
All SFPs used in Magnum 6KQs are compliant with the industry standard Multi-Source
Agreement (MSA) ensuring compatibility with a wide range of networking kit.
Side View ---Duplex LC connector -- Front view
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 100mts (328
ft.).

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 the device if
required.
If connected properly, you can check via
(MNS-6K)software too for verification the
validity of SFP Gigabit ports.
Make sure Rel 3.6 or higher firmware is
loaded on the 6KQ switches to support the
SFP transceivers.
3.3 DIN-Rail Mounting the Magnum 6KQ
The Magnum 6KQ is designed for use in a “factory floor” industrial
environment. It is available with optional DIN-Rail brackets to mount it securely in a
metal factory floor enclosure, maintained vertically for proper convection cooling of the
unit. The Magnum 6KQ requires one DIN-Rail mounting clip or latch for secure
mounting. These may be ordered as Model # DIN-RAIL-6KQ. See a 6KQ viewed from
the side, at the left, with model DIN-RAIL-6KQ in place on the unit.
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)
26
www GarrettCom com
..
The Din Rail Latching clips are mounted on the upper side
corners of the 6KQ unit. Two threaded holes are provided on the sides of 6KQ for DIN-
Rail mounting purposes. See side view at the left. The required two screws are included
with the DIN-Rail brackets, and are no.10-32 X 3/8 PHIL. PAN w/star washer. The two
heavy-duty Din-Rail latches are designed as if that they can be manually accessed from
the top when the 6KQ is installed on a DIN Rail.
To install the 6KQ with the DIN-Rail brackets and latches attached to it, hold the
6KQ in the side vertical position with the bottom out, and with the top moved in toward
the DIN-Rail. Position the latches over the top of the DIN-Rail. Then, snap the latches
into holding position by moving the bottom of the 6KQ inwards to a vertical position.
The DIN-Rail latches and brackets are heavy duty, and will hold the 6KQ securely in
position, even with cabling attached to the unit.
To release the 6KQ from the DIN-Rail mounting, press the top of the two DIN-
Rail latches down simultaneously to release the 6KQ so that it can be dismounted by
pulling the bottom out. Once the bottom of the 6KQ is rotated out, the DIN-Rail latch is
not engaged and the 6KQ can be moved up and out, free of the DIN-Rail mounting.
The picture in Section 3.3 shows vertical mounting of Magnum 6KQ as it about
to be mounted on a DIN-Rail track for proper convection cooling of the unit. Note that
there is air space in the rear, as the 6KQ unit is held out from the rear of the panel by the
mounting brackets. The 6KQ design uses the case for cooling (patent pending), and
needs to be mounted vertically with air flow space around it in the front, rear, and sides.
The DIN-Rail mounting brackets and latches are optional and need to be ordered
as separate items, e.g Model # DIN-RAIL-6KQ
3.3.1 Mounting Dimensions for 6KQ with metal brackets
Each Mangum 6KQ is supplied with metal mounting brackets and screws to
mount the unit securely on a panel or wall. It is recommended to mount the 6KQ
vertically, as shown below, 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 that the metal brackets supplied hold the back of the 6KQ unit out from the
panel or wall behind it, creating a rear space of about ¼ inch or 1cm. This allows
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)
27

..
air circulation and cooling of the rear part of the case.
For best cooling of the 6KQ, attach the metal brackets to metal (rather than wood
or plastic). Attaching to metal helps conduct heat away from the 6KQ thr ough the
metal brackets and into the metal support structure.
Since the 6KQ 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.
The unit is mounted using the brackets as shown in the illustration above. The spacing
for the mounting screws into the supporting wall or panel is a rectangle 21.74 x 11.91 cm
(8.56 x 4.69 inches) center-to-center.
3.4 Powering the Magnum 6KQ Managed Field Switch
The DC internal power supply supports installation environments where the
DC voltage is from 18 to 150 volts depending on the model selected. The power

consumption will range from about 20 up to 35 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.
Power input options are available to suit the 6KQ Switches to special high-
availability communications and/or heavy industrial-grade applications, including:
* -48VDC, 24VDC and 125VDC with single DC input,
* -48VDC, 24VDC and 125VDC with dual-source DC input
External AC power supplies are optional, see Section 1.2, Ordering Information.
See the Appendices of this manual for more details. Use an RFQ for other variations.
3.5 Alarm Contacts for monitoring internal power, and Software Traps
The Alarm Contacts feature, standard on Magnum 6KQ’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 6KQ 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 top two pins (1,2) are software operated
3. The bottom two pins (3,4) are hardware
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. (Chapter 19).

3.6 6KQ Port Module (6KPM) Installation
Magnum 6KQ Switches are normally received from the factory with all
required 6K Port Modules installed.
NOTE: There may be situations where the 6K PMs need to be added or replaced.
Any change in configuration of the modules can be done only via factory
installation. There is no field upgrade option for 6KQ port modules. Please contact
Tech Support (support@garrettcom.com
) / RMA(rma@garrettcom.com) for
changing modules.
The 6KQ port modules are not compatible with or inter-changeable with the other
Magnum 6K-Family Switches’ PMs, which use larger (typically 8-port) modules.
3.7 Connecting a Management Console Terminal to Magnum 6KQ
(Serial-RJ-45 Console Port)
The serial console port on the Magnum 6KQ is
different from other 6K-family switches. The Serial RJ45 port, as shown in the picture, requires an 8-pin RJ45 male connector to have the proper communication.
(Note - the serial RJ-45 console port on the Magnum
6KQ is compatible with Cisco-type RJ-45 console port
cables).

NOTE for Power Substations
: In support of the IEEE 1613 Class 2 standard, GCI
advises that, for substation applications, the serial RJ-45console 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 packetloss testing per the 1613 standard-defined test procedure.
4.0 OPERATION
This chapter describes the functions and operation of the Magnum 6KQ
Switch.
4.1 Switching Functionality
A Magnum 6KQ provides switched connectivity at Ethernet wire-speed among
all of its ports. The Magnum 6KQ supports10/100Mbs for copper media and 10 or
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 6KQ,
but local traffic on a port will not consume any of the bandwidth on any other port.
The Magnum 6KQ 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 6KQ-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
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)
31
www GarrettCom com
..
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 6KQ 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 6KQ 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 6KQ 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.
4.2 Status LEDs
For Magnum 6KQ models (/6KQ) :
PWR : Power LED, ON when external power is applied to the unit.
LK : Steady ON, Link status for 10 Mbps and 100Mbps operation.
ACT : ON with port activity for 10 Mbps and 100Mbps operation.
F/H : Full / Half duplex LED, ON when the port is running full duplex,
OFF for half duplex.
100/10 : Speed LED, ON when the speed is 100Mbps , OFF when the
speed is 10 Mbps
4.3 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 6KQ’s copper port to other
devices. Operation is according to the IEEE 802.3u standard.
The Managed 6KQ’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 (2.2.9 at page no.14) of
this manual to access the “6K-MNS(Rel 3) Software user guide”
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)
32
www GarrettCom com
..
One frequently-used application for the Managed Magnum 6KQ 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 6KQ 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 6KQ 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 6KQ’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
-- 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
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)
33
www GarrettCom com
..
account for all devices and cable lengths within that domain. For Magnum 6KQ Fast
Ethernet switched ports operating at 100Mb half-duplex, the bit time delay is 50BT.
4.4 Flow-control, IEEE 802.3x standard
Magnum 6KQ 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 6KQ 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 6KQ 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 6KQ 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.
4.5 Power Budget Calculations for 6KQ PM’s 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) = P
T
(min) - PR(min)
where P
T
= 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 50/125
m (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)

* Note: The use of either multi-mode or single-mode fiber to operate at 100Mbps speed over long
distances (i.e., in excess of approx. 400 meters) can be achieved only
if the following factors
are both applied:
The 100Mb fiber segment must operate in full-duplex (FDX) mode, i.e. the full-duplex
(factory default) setting for 100Mbps fiber ports must be used, and
The worst-case OPB of the fiber link must be greater than the fiber cable’s passive
Attenuation.
(Attenuation = Cable loss + LED aging loss + Insertion loss + safety factor)

This chapter describes each Port Module (PM), including appearance,
functionality, and status displays.
5.1 Inspecting the Package and Product
This section applies only to Port Modules shipped as separate items, i.e., 6KQ
PMs that are not factory installed.
Examine the shipping container for obvious damage prior to
installing a 6KQ PM; notify the carrier of any damage you believe occurred
during shipment. Inspect the contents of this package for any signs of damage
and ensure that the items listed below are included.
The package should contain:
1 or more 6KQ Port Moduless
Installation instructions with illustrations
Observing proper ESD grounding procedures, remove the 6KQ
PM(s) from the shipping container. Be sure to keep the shipping container
should you need to ship any of the PMs separately at a later date. In the event
there are items missing or damaged, contact your supplier. If you need to return
the unit, use the original shipping container if possible. Refer to Chapter 5 for
specific return procedures.
5.2 6KQ Modules
An important feature of the Magnum 6KQ 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 6KQ Switches are fixed RJ-45 copper
ports with dual-speed 10/100Mbps auto-negotiating capability. Additionally the
switch can accept up to three Port Modules to provide the user with up to 12
additional ports (16 total) providing a wide selection of Ethernet copper and
fiber media connections with 10, 100 and 1000Mbps capability and up to 70km.
Note: The 6KQ 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 6KQ Port Modules,

Four-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.
Each port has an Activity (ACT) LED indicating packets being received, a
Link (LK) LED that indicates proper connectivity with the remote device when lit, a
FDX/HDX LED to indicate full-duplex mode when lit (or half-duplex when off), and a
“10/100” LED indicating 100Mb when lit (or 10 Mbps when off).
Note: The 10/100 RJ-45 ports are supported with Auto-negotiation and Auto-
crossover (MDIX), which allow the RJ-45 ports to automatically Link with any
RJ-45 device and eliminate the use of cross-over cable.
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 6KQ. It is not recommended to use these ports in
substation applications to interface to field devices across distances which
could produce kigh (greater than 2500V ) levels of ground potential rise (GPR)
during line-to-ground fault conditions. The 6KQ passes the 1613specifications
for zero packet loss with fiber ports & with RJ-45 ports used as indicated here.
5.2.10 PoE power-pass-through, Base unit Model 6KQP-48VDC, 10/100Mb 4-port
See Section 2.2.3 for basic PoE ports information.
The LEDs on PoE ports are slightly different compared to regular (non-PoE)
RJ-45 modules.. When the PoE port is in use, the PoE LED is ON when connected
properly to a 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.
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 being 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 source must be strong enough to provide power
to the 6K switch and to all the 4 RJ-45 ports with PD devices connected (up to
15 watts per PoE port).
Magnum 6KQ Managed Field Switch Installation and User Guide (04/07)
42
www GarrettCom com
..
In the case where the 48VDC power in not internally connected 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 will still operate
properly for data traffic.
5.2.11 SFPs, Gigabit (1000Mbps) port modules
The Magnum 6KQ offers a Gigabit option with multiple choices of copper
10/100/1000Mbps or Gigabit SFP Fiber modules for the modular slot. While up to two
Gigabit modules
(maxm.) can be
configured in the
modular slot D only.
The 6KQ
Modules provide a
GBIC opening for
insertion of
industry-standard
SFPs to provide
Gigabit (Gb) media
flexibility. SFP fiber Transceivers are available with both multi-mode (550m) at 850nm
and single-mode at 1330nm (10, 25, 40, 70)km fiber options, and for Gigabit copper as
well, with new models appearing often.
The 1000Mb Gigabit SFP fiber-port modules on the Magnum 6KQ are
normally set (factory default) to operate at AUTO mode for best fiber distance and
performance. Only two Gigabit ports can be configured on a Mangum 6KQ managed
switch in slot D.
There are three LEDs provided on each SFP Gigabit port module. The SFP Gigabit fiber
has LEDs that indicate LK (Link status) and ACT (receiving activity) when lit and F/H
(on for Full and OFF for half duplex) for that port.
The copper Gigabit port supports 10/100/1000Mb speeds. The three LED’s show the
speed the connection has achieved. It is set as AUTO by default. All other LEDs are the
same as the SFP fiber.

APPENDIX B : DC Power Input
B1.0 Specifications for Magnum 6KQ Switches, DC Power at 24V and –
48V and 125V DC Power input
Each Magnum Model 6KQ Managed Switch requires DC power input, at either
24VDC, -48VDC or 125VDC nominal. The wide range of DC power input types
qualifies this product for use in 24VDC, -48VDC as well as 125VDC applications in
different industries.
DC Power Terminals: “+”, “
-” are internally floating so that user may ground either
GND: ground wire connection to the 6KQ chassis screw
Power Consumption:
35 watts typical (for a fully loaded fiber model)
12 watts typical (for a small 4 port copper-only model)
24VDC Power Input nominal (18 to 36VDC range)
-48VDC Power Input nominal (36 to 60 VDC range)
125VDC Power Input nominal (88 to 150VDC range)
Standard 6KQ DC Power Input Terminal Block : “ -, GND, + ”
See also Section 1.0, Technical Specifications, for the 6KQ base unit
B2.0 -48VDC, 24VDC and 125VDC POWER, THEORY OF OPERATION
The -48VDC, 24VDC and
125VDC 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 connection, for example, will neither affect the Switch, its internal
power supply, nor will it blow the fuse in the internal power supply.
B3.0 APPLICATIONS FOR DC POWERED ETHERNET SWITCHES
Magnum 6KQ Switches are easily installed in a variety of applications where 48VDC, 24, or 125VDC 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.
B4.0 6KQ, -48V, 24, 125VDC INSTALLATION
This section describes the proper connection of the -48VDC leads (or 24VDC /
125VDC leads) to the DC power terminal block on the Magnum 6KQ Switch. The DC
terminal block on the Magnum 6KQ 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 6KQ 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 “+”.

With the exception of the dual DC input power connections and the power
supply, all specifications and configuration options for the Magnum 6KQ -48VDC,
12VDC, 24VDC, 125VDC and 250VDC models with this Dual-Source option are identical
to those listed in the Magnum 6KQ Field Switches Installation and User Guide,
including Appendix B “Internal DC Power Supply Option”
C2.0 MAGNUM 6KQ, with -48VDC, 24VDC and 125VDC Dual-Source option
The 6KQ-Switch models with the internal -48VDC, 12VDC, 24VDC, 125VDC
and 250VDC Dual-Source power supply are designed for installations where a battery
plant is the power source, and where two separate power sources are utilized in order to
increase operational uptime and to simplify maintenance.
The functionality of the Magnum 6KQ Switch -48VDC, 12VDC, 24VDC,
125VDC and 250VDC Dual-Source Option units is identical to the standard AC-powered
models. Refer to the main sections of this Installation and User Guide for a detailed
description of the Magnum 6KQ Switches.
C3.0 DUAL-SOURCE OPTION, THEORY OF OPERATION
The Dual-Source DC power
option is designed using diodes inside
of the 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.

C5.0 INSTALLATION
This section describes the proper connection of the -48VDC, 12VDC, 24VDC,
125VDC and 250VDC dual source leads to the power terminal block on the Magnum
6KQ Switch (shown in Figure to the above)
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 6KQ 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.
