2.2 Product Description - Magnum 6K32TRC Managed Switch

The IEC61850 complied and attributed with “green” environmentally
friendly, Magnum 6K32TRC Managed Switch is specially designed with a convection
cooled thermal design techniques to minimize heat generation to provide an efficient,
highly reliable and secured Ethernet solution for heavy duty Industry, Power sub­stations and temp-uncontrolled outdoor applications. Specially designed and enclosed

in a “Reverse” aluminum case, the 6K32TRC proudly offered with modularity, port
density (up to 32 ports max.) and security in a 1U rack-mount package.

Being a sibling of the successful 6K managed switch family, the Magnum
6K32TRC supports modularity in the last two slots to configure with any of the various

6KP modules offered. The Magnum 6K32TRC provides effective and economical
Ethernet solutions with 16 10/100 RJ-45 ports fixed and two modular configuration slots.
The two modular configurable slots of the Magnum 6K32T offer the flexibility to
configure up to sixteen 100Mb, (RJ-45 and 16 fiber ports) or a maximum of four
Gigabit(1000Mb) options to handle high bandwidth application efficiently. The two
modular slots are boosted with 10Mb/10/100Mb/ 100Mb/1000Mb and can be configure
with any of modules offered with copper or Fiber media or combo. The various PoE
modules option is an additional advantage for Magnum 6K32TRC users to provide a
secure and economical solution to critical remote applications.

The preloaded robust and intuitive MNS-6K Managed Network firmware with
multiple secured managed features is able 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

include SNMPv3, SSL/SSH, 802.1X, TACACS+, Port Security, and Tagged VLANs
and a secured user friendly web based option. The IGMP feature for multicast traffic

and streaming video application and IGMP-L2 mode feature is an attempt to provide a
Layer 3 solution with 6K-Switches effectively and economically.

The Magnum 6K32TRC‘s port flexibility can be achieved via a family of 6K
port modules (6KPM). These modules come with 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 (1+1) Dual Gb port module selections using GBIC transceivers
in copper or fiber. 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 as per the user’s
application and Ethernet media requirements. Evolving mixed-media requirements for
10Mb and 100Mb fiber, copper, and 1000Mb Gigabit ports can be easily handled by the
Magnum 6K32TRC product reliably

Magnum 6K32T & 6K32TRC Managed Switch Installation and User Guide 05/07)

In an eight-port SFF fiber port module, all of the fiber ports are of the same
speed (100Mb), mode, and connector type. Models that 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 6K32T & 6K32TRC
normally are set (factory default) to operate in full-duplex mode for best fiber distance
and performance. Using the 6K32T & 6K32TRC’s MNS software, the user may select
full- or half-duplex mode per-port through the set-up of the software (See the Magnum
6K32T & 6K32TRC 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.

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 auto­negotiation is not disabled).

an RJ-45 port and the Link (LK) indicator for that port must be ON (indicating there is a

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

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 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

The 6K32T & 6K32TRC modules provide a GBIC opening for insertion of industry­standard 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 6K32T & 6K32TRC
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 full­duplex mode at any time. The Gigabit fiber port has LEDs that indicate LK (Link status)
and ACT (receiving activity) on that port when lit.

For Dual Gigabit modules option, please check page#60 for details info.

Magnum 6K32T & 6K32TRC Managed Switch Installation and User Guide 05/07)

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
6K32T & 6K32TRC can do its part to prevent any QOS degradation while it is handling
Ethernet traffic through its ports and buffers.

The Magnum 6K32T & 6K32TRC 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 (R3) 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 6K32T & 6K32TRC’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 cut­through 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-and­forward operation is that more bandwidth is available for good packets when the traffic
load is greatest.

When the Magnum 6K32T & 6K32TRC 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.
