2.2 Product Description - Magnum 6K32 Managed Switch
The Magnum 6K32 Managed Switch provides high port density, with up to 32
ports in a 1U rack-mount package. It is used to boost the performance of large Ethernet
LANs, typically serving as a “backbone” switch in carrier-class (Telco) or Industrial
applications. Being a member of Magnum 6K-family, the Magnum 6K32 has modularity
via a selection of 20 different modules where any one may be configured in the A slot,
and proven reliability for heavy duty applications. It has 24 ports of 10/100 RJ-45 ports,
plus a mix of fiber and copper ports, 10 Mb or 100Mb or Gigabit, in the modular slot.
The Magnum 6K32 is equipped with MNS-6K Managed Network Software to
handle industry-standard IEEE 802.1p QOS prioritization and non-blocking wire speed
on all ports. It provides high performance switching services for both “smooth”
streaming and “bursty” data traffic. For redundant LANs, it offers S-ring, Link-Loss-
Learn, STP and RSTP. Security features include SNMPv3, SSL/SSH, 802.1X, Port
Security, and TaggedVLANs. See MNS-6K materials for further details about software.
The Magnum 6K32’s port flexibility is achieved via a family of 6K port
modules for copper and fiber-built-in (emphasizing Small Form Factor fiber for high
fiber port density), 6-port modules for fiber and RJ-45 combinations, and 1Gb or 2Gb
port module selections using GBICs. These modules can be factory configured in a base
chassis unit (or may be changed in the field by trained technicians) to adapt the unit to
the user’s application and Ethernet cabling requirements. Even evolving mixed-media
requirements for 10Mb and 100Mb fiber and copper as well as Gigabit ports can be
handled by the Magnum 6K32 product.
The packaging and power-input options target the Magnum 6K32 at heavy-
duty applications. The chassis mounting rack style may be “regular” (with the ports and
LEDs in the front and the power input and management console connector in the rear) or
“Reverse” (with the ports and LEDs and the power-input and the management console
connector all in the rear and a duplicate set of LEDs in the front). Rack widths
accommodated include standard 19” RETMA, ETSI, and 23” Telco. Input power may be
AC, or –48VDC for Telco environments, or 24VDC for Industrial applications.
Designed for use in network traffic centers, the Magnum 6K32 provides high
performance plug-and-play hardware operation, 802.1p packet prioritization in hardware,
and industry-standard managed networks software functionality, all in convenient 1U
rack-mount packages.

2.2.1 Magnum 6K32 and 6K32R chassis
The Magnum 6K32 is a 19” rack-mountable Ethernet Switch with fixed 24
10/100 RJ-45 ports and a modular slot (8 ports max.) for configuration flexibility. The
modular slot, shown on the right side below, may be configured with any of a large
selection of fiber and copper port types and combinations of types, typically eight ports
module max., but sometimes six (4+2) or four(2+2) or (4+4) ports or even one (G+4) or
(G+2) or two Gb (GBPMV-2OTX) port module. The modular slot may be configured
with a Gb module that accepts GBICs. The port types configurable using the modular
slots allows the 6K32 to efficiently serve a large variety of applications, even those using
some fiber media. The Magnum 6K32 port modules are normally factory installed, but
may be changed or added in the field. (See Section 5) Status LEDs are part of each port
module and are viewable when connecting the Ethernet media. A “regular” rack-

with 6KP6-RJMSC
mount 6K32 is shown in Figure 2.2.1a. On “Reverse” rack-mount models, all the ports
and power supply are on the rear part of the box, whereas the 2
nd
set of the dual LEDs
(front and back) for port status are in the front. Of course, with the web based
management option or by the use of SNMPc 3
rd
party software, the port status data can
also seen through GUI software on remote computers and terminals.
Designed for use in Carrier Class and Industrial networks with some segments
requiring Gigabit backbone interconnections among network centers, the managed
Magnum 6K32 is easy to deploy, manage and maintain. Addresses of attached nodes are
automatically learned and maintained, adapting the switching services to network
changes and expansions to provide pug-n-play operation.
The modules that may be configured and used in Slot A are described here.

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 are 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
6K32’s normally are set (factory
default) to operate in full-duplex
mode for best fiber distance and
performance. Using the 6K32’s
MNS software, the user may select full- or half-duplex mode per-port through set-up of
the software (See Magnum 6K32 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 6K32’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 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 details)
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 MNS-6K software, the user may disable auto-negotiation and fix the
desired operation of each RJ-45 port. MNS-6K Software allow to 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). See Section 4.3 for Up-Link switch.
2.2.4 Six-Port “4 + 2” Combo Modules, 4@ 10/100 RJ-45 and 2@ 100Mb fiber

mode fiber ST, SC or single mode SC or Long Reach SC ports. For ports numbering,
ports 1,3,5,7 are copper, ports 2 and 6 are fiber, ports 4 and 8 are not present.
The four RJ-45 ports operate just like the 8-port copper module, and the two fiber ports
operate at 100Mbps full-duplex (default). User mode control per port through the MNS
software is also the same. See Section 4.3 for Up-Link switch on port 1.
On Magnum “4+2” Combo modules, there are four LED’s for each RJ-45 port,
which indicate status the same as described for the 6K8-RJ45 in Section 2.2.3 above. The
fiber port’s 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, and with 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, please check section 2.2.5.
2.2.5 Four-Port 10 Mb mm Fiber ST Modules
The 4port @10Mb ST fiber modules behave the same as the 8@100Mb ST
fiber modules except for the 10Mb speed. For ports numbering, ports 1, 2, 5, 6 are
present, ports 3, 4. 7, 8 are not present. The default setup on the 10Mb fiber module is
half-duplex, which allows the Magnum 6K32 Switch to connect to any 10Mb hub or
media converter or almost any other device with a 10Mb fiber Ethernet port. User mode
control per port through the MNS software is the same as the other 6K32 modules. The
fiber ports support fiber cabling distances according to the 10BASE-FL standard, i.e.,
2km distance for multi-mode fiber. (Single-mode for up to 10Km distance may be
available as a special order configuration).

2.2.6 Gigabit (1000Mbps) port modules
The Magnum 6K32 offered a wide option Gigabit speed with multiple choice
for the modular slot. While up to two Gigabit modules (maxm.) can be configured in the
modular slot. The Gigabit port option for the modular slot comes in couple of different
configuration. The two Giga port has been offered as GBPM-2OTX (fiber or RJ-45),
whereas the single Gigabit module comes in flavor of G+4(10/100 RJ-45 ports) or G+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 6K32 modules provide a GBIC opening for insertion of industry-standard GBICs to
provide Gigabit (Gb) media flexibility. GBIC models are available for both multi-mode
(550m) and single-mode (10, 25, 40, 70)km fiber options, and for Gigabit copper as well,
with new models appearing often.
The 1000Mb Gigabit fiber-port modules on the Magnum 6K32 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 at AUTO mode, and can be fix at 1000Mbps speed full-
duplex mode at any times and has LEDs that indicate LK (Link status) and ACT
(receiving activity) on that port when lit.
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
6K32 can do its part to prevent any QOS degradation while it is handling Ethernet traffic
through its ports and buffers.
The Magnum 6K32 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 6K32’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 6K32 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.
Another feature implemented in Magnum 6K32 Switches is a collision-based
flow-control mechanism (when operating 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 to stop incoming traffic.
