and traffic control systems, power utilities and industrial factory-floors. For the fast
growing demands of video surveillance systems with segments requiring Gigabit
backbone interconnections, the Magnum 6K8 managed switches are easy to install and
operate with Magnum 6K management firmware.
The advanced generation of industrial applications requires advanced managed network
software, operation at extended
temperatures, fiber ports modularity,
support for self-healing ring structures,
redundancy, security and gigabit backbone
configurability. The Magnum 6K8 has all
of these, in a very tough and robust metal
case with a wide choice of popular DC
options or industry standard AC internal
input.
The plug-n-play Magnum 6K8 Industrial
Field switches, should be mounted vertically using
the vertical mounting brackets which come along
with the unit or by using the DIN-RAIL-KIT
(optional) for Din rail mounting.
Loaded with versatile and secured management
software (MNS-6K), the 6K8 switch can be easily
managed and monitored via SNMP or secured Web.
Supporting dual Gigabit ports (copper or fiber) in
one slot defines the Magnum 6K8 Field switches role as an effective Managed Gigabit
media converter Switch that meets any secured Gigabit media requirements.
Dual LEDs on the front and Top side help the vertically mounted 6K8 to be monitored
easily. The modular designed Magnum 6K8 Industrial Field switch can support a
maximum of two Gigabit modules (fiber or copper) to meet any demand of bandwidth
required applications. In an on-going demand of diversified designed Ethernet
applications, the Magnum 6K8 is a fine solution to meet and satisfy any requirements
through its rich modular structure. The Relay contact for external “ALARM” is another
additional feature which allows the Magnum 6K8 to monitor the internal power failure

24V/-48V/125VDC power options offer a widely accepted managed switch with high
reliability.
2.2.2 Eight-port SFF fiber modules (6K8-MTRJ, 6K8-MLC), 100Mb
fiber
Fig.2.2.2 :
SFF Fiber Port
Modules,
6K8-MTRJ (to the left)
and
6K8-MLC or -SLC
(below)
In an eight-port SFF fiber port module, all of the fiber ports are of the same
speed (100Mb), mode, and connector type. Models available with Small Form Factor
(SFF) are multi-mode MT-RJ or LC-type connectors, and single-mode LC-type
connectors.
The 100Mb fiber eight-port
modules for the Magnum 6K8-Series
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-up of the software (See Magnum
6K-MNS Software Manual) for the 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 when ON (half-duplex when OFF), and 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.

2.2.3 Eight-Port Copper Module, 6K8-RJ45
The 6K8-Series’s 8-port Copper port module, model 6K8-RJ45, provides eight
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). The auto-crossover feature will
automatically determine the other side of connection to make the connection, and
eliminate the need of cross-over cable.
On the model 6K8-RJ45 module, there are four LEDs for each port, two in the
connector and two separate. 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 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 6K8-Series (MNS-6K) management software, the user may disable
auto-negotiation and fix the desired operation of each RJ-45 port. User may select 10Mb
or 100Mb speed and full- or half-duplex mode per-port as per user requirement. (See
Magnum MNS-6K Software Manual for details info.).

(MDIX) features to eliminate the use of cross-over cables. The two fiber ports operate at
100Mbps full-duplex (default). User mode control per port through the MNS software is
also the same.
On Magnum “4+2” Combo modules, there are four LED’s for each RJ-45 port,
which indicate status as described for the 6K8-RJ45 in Section 2.2.3 above. The fiber
port LEDs indicate status the same way as described for 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.
The Magnum Combo six-
port modules are also available with
4@ MTRJ 100Mb mm SFF fiber and
2@10Mb fiber mm ST ports, or 4@
RJ45 10/100 copper and 2@10Mb
fiber mm ST ports. The
4@ RJ-45 + 2@ 10 Mb ST operation of the SFF fiber and the RJ-45 half of
the module 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.
2.2.5 Four-Port 10 Mb and 100Mb mm Fiber ST Modules
The 4-port @10Mb ST fiber modules behave the same as the 4@100Mb ST
fiber modules except for the 10Mb speed. For port numbering, ports 1, 2, 5, 6 are present,
ports 3, 4. 7, 8 are not present. There is also a similar 100Mb fiber SC module.
The default setup on the 10Mb fiber module is half-duplex, which allows the
Magnum 6K8-Series 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 6K8-Series 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
up to greater distance may be available as a special order, request quote).

2.2.6 Gigabit (1000Mbps) port modules
The Magnum 6K8-Series offers a wide range of optional Gigabit modules and
one or two Gigabit ports can be configured in one modular slot. The Gigabit modules are
the two port GBPMV-2OTX , the 6KP5V-G4RJ (single Gigabit+4 10/100 RJ-45 ports)
or the 6KP3V-G2SC (single Gigabit+2 100Mb fiber ports) as shown below in the figure.
1@ 1000Mb Fiber SC + 2@ 100Mb SC 1@ 1000Mb Fiber SC + 4@10/ 100Mb
The 6K8-Series Modules provide a GBIC opening for insertion of industry-standard
GBICs to provide Gigabit media flexibility. GBIC models are available for both multi-
mode (550m) and single-mode (10, 25, 40, 70) km fiber options. Gigabit copper is also
available with new models appearing often.
The 1000Mb Gigabit fiber-port modules on the Magnum 6K8-Series are
normally set (factory default) to operate at AUTO mode for best fiber distance and
performance. The 1000Mbps SC fiber-optic module on the Gigabit -SX and Gigabit-LX
transceivers are compatible with the IEEE 802.3z Gigabit standards.
There are two LEDs mounted on each Gigabit port module. The Gigabit fiber
port is by default configured to AUTO mode, and can be fixed at 1000Mbps speed full-
duplex mode at any time. The Gigabit fiber port has LEDs that indicate LK (Link status)
and ACT (receiving activity) on that port when lit.
NOTE: For detail information about the various port module 6KPMV options being
used for Magnum 6K8, please check section5.2, 6KPM Module Description.
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
6K8-Series can do its part to prevent any QOS degradation while it is handling Ethernet
traffic through its ports and buffers.

The Magnum 6K8-Series 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 (Rel3) 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 6K8-Series’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 6K8-Series 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 packets to cause “flow control”. This tells the sending devices to
temporarily stop sending traffic, which allows a traffic catch-up to occur without
dropping packets. Then, normal packet buffering and processing resumes. This flow-
control sequence occurs in a fraction of a second and is transparent to an observer.
Another feature implemented in Magnum 6K8-Series 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. The flow control option is user configurable (enable/disable) through the setport
command of MSN-6K software as per the requirement of a network.
