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.

Magnum 6K32 Managed Switch
Installation and User Guide (02/05)
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-
Figure 2.2.1a: 6K32 front view, configured for 24 RJ-45 ports + 1 Modular slot
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 2nd 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 3rd 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.

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

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

Magnum 6K32 Managed Switch
Installation and User Guide (02/05)
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.

Features and Benefits
„ Managed switching for high performance Ethernet LANs
Magnum 6K32 Switches provide non-blocking (all ports can run at full speed at once)
performance with standard Managed Networks Software (MNS-6K) included. They
are typically used in LAN traffic centers with 24 10/100Mb ports or one or 2 Gigabit
ports for backbone connections, where managed network services are desired.
„ Switching services includes 802.1p QoS packet prioritization
The Magnum 6K32 switching hardware supports QoS, giving packet processing
priority to priority tagged packets according to the IEEE 802.1p standard. For port-
and application-specific priorities, the QoS software may be configured by the user.
„ Features Fiber-Built-In
Magnum 6K32 Managed Switches are designed at modular slot to naturally include
fiber ports, and support mixes of multi-mode and single-mode; 10 Mb, 100Mb and
1000Mb speed; full-and half-duplex; classic Small Form Factor (SFF) and GBIC fiber
connectors. RJ-45 10/100 ports can also be configured in the mix of port types.
„ Modular design for port flexibility, in a 1U space-saving rack-mount package
The 1U Magnum 6K32 chassis has 1 slot for port configurations. A family of 2, 4, 6 or
8 port modules allows the user to select the desired mix of port types and speeds.
There are over 20 different modules in the family to choose from. The port modules
are normally factory installed and tested, but may be changed in the field.
„ Rack-mounting may be standard or “reverse”, 19 inch or ETSI or 23” Telco
The standard rack mounting provides Ethernet ports and status LEDs in front, service
connections (power input and management console) in the rear. “Reverse” rack
mounting provides status LEDs in front and all cabling connections in the rear.
Standard 19’ rack mount brackets are included, with ETSI and 23” Telco optional.
„ Standard AC power input, -48VDC or 24VDC or 125VDC input is optional
Standard AC power input is IEC plug, auto-ranging for worldwide use. For special
applications, models with –48VDC or 24VDC or 125VDC are available. Dual Source
DC input can also be selected and configured on the DC power input models.
„ Heavy-duty design for Telco (NEBS tested) and other industrial environments

Applications
Magnum 6K32 Fiber Switches offer high performance and a modular slot
options to fulfill the choice of copper/Fiber, 10 or100 or 1000Mb requirements. They
offer the flexibility of 100Mbps fiber and copper ports as well as Gigabit ports in the
modular slot, along with MNS-6K management software. Magnum 6K32 Switches are
used in a variety of applications including Carrier-class (Telco), client/server computing,
secure VLAN- performance upgrades to departmental networks, and LAN traffic centers
that require Gb backbone services. The performance characteristic of the 6K32 Switches
enables them to inter-connect a series of subnets (one subnet per 6K32 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 mode.
The mixed-media capability in modular slot is ideal for upgrading existing
Ethernet LAN networks where existing cabling must be accommodated. The fiber-built-
in media capability provides future-proof fiber cabling for the LAN structure.
Example 1 : Magnum 6K32 Switch for a VLAN application
Equipped with lots of advanced management features, the Magnum 6K32
Managed switch is able to handle a VLAN application and provide security and
performance in an Ethernet network center. A secure VLAN-enabled network is simply
an administratively-configured broadcast domain. The network administrator determines
which ports and nodes are in which broadcast domains by setting membership profiles
for each of them. The Magnum 6K32’s VLAN capability can be configured in two types
of virtual LANs; Port-based VLANs and Tag-based VLANs.
In an office environment where departments such as Finance, Engineering,
R&D, and Marketing need to keep a secure LAN, the 6K32’s VLAN feature will prevent
traffic cross-over among traffic domains, and thus keep sensitive data and information
controlled. The Managed Magnum 6K32 equipped with VLANs capability is ideal for
any application where a secure VLAN to multiple departments is needed.
The modularity of the 6K32 Managed Switch makes it an attractive choice for
use in applications with LAN connections to an organization’s multiple site offices. The
different offices can be easily connected together with the Fiber ports supported by the
Magnum 6K32 Switch. A main NT-server in a secure area protected from earthquake or
fire hazards can be connected to one or two full duplex Gigabit Fiber ports.

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 6K32 Switch helps create a database of all the network subnets
to easily manage the network. Secure web-based management is also included, with
authentication and encryption to keep out even determined trouble-makers.

Example 2. In another Telecommunications storage data application, a secure managed
switch is required to provide an Ethernet backbone for a diversified network with
multiple subnets. The back bone consists of high speed LAN segments supported by
1000Mbps full-duplex future-proof fiber media to provide secure long distance LAN
connections. 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 building. The entire spread network is
managed to provide easy, detectable, uninterrupted support through a viewable SNMP
monitor.
The Magnum 6K32 Managed Switch equipped with copper and optional dual
Gigabit fiber ports on modular slot provides an economical and seamless solution to the
requirements. The user-configurable Magnum 6K32 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, Port security, 802.1X, and other security features to provide a secure and stable
network as per the requirement
The 6K32 Managed Switch with NEBS Level 3 compliant and management
flexibility allows the users more than one configuration alternative. The user has an

Example 3 Redundant Application
In a redundant application for high network availability where a rack-
mountable managed switch with over 24 ports is required with dense port
features, Magnum 6K32’s equipped with redundant LAN features like S-Ring,
RSTP, Link-Loss-Learn and various security features are easily qualified for the
application. The -48VDC input power option with Dual Source is a useful
option in telecom central offices.
The Magnum 6K32 with two Gigabit ports in the modular slot allows it
to connect into a Gb mesh structure with RSTP and S-Ring combo used in a no-
single-point-of-failure self-healing LAN topology along with a ring of multiple
6K25s at the edge to efficiently recover from a fault in the network. The
industry standard Rapid Spanning Tree Protocol 802.1d is used in top eight
switches (see diagram below) to perform GB mesh fault recovery, whereas the
bottom ring setup has been configured with S-Ring and Link-Loss-Learn for
faster recovery in a big ring.
A redundant LAN setup not only provides a reliable recovery solution

from network faults, but also improves operating up-time to simplify
maintenance and save money and valuable time. In a critical application where
secure data has been stored in a data mining storage facility, a redundant
network provide a more secure solution.
The figure below has Magnum 6K32’s and 6K25’s connected over the
gigabit mesh structure for a high bandwidth secure redundant LAN setup.

Magnum 6K32 Managed Switch
Installation and User Guide (02/05)
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 environmental temperature around the equipment
must be less than or equal to 500C.
2.) If the equipment is mounted in an enclosed or multiple rack
assembly, adequate air flow 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 6K32 Switches, as well as
connection of the various Ethernet media types.
3.1
Locating Magnum 6K32 Switches
The location of a Magnum 6K32 Switch is dependent on the physical layout of
the network. Typically the Switch is placed in a central wiring location where groups of
network devices need to be connected in order to communicate with each other. These
Switches are typically rack mounted in a wiring closet see Section 3.3.2 below), but
because they have rubber feet they can also be installed on a shelf or table top unit. The
compact size allows it to be easily placed in an office or lab area, and it can also be either
shelf of wall-mounted (see Section 3.3.1 below).
Locate an AC receptacle that is within six feet
(2 meters) of the intended Magnum 6K32 site. The
rugged metal case of the Magnum 6K32 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 the small fan on the
left side, while the unit is in operation. See figure below.
Figure 3.1: Location of the Magnum 6K32’s cooling fans
3.2
Connecting Ethernet Media
The Magnum 6K32 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 port Modules which can be

individually selected and configured per-port. See Section 2.4 for a description
of the PMs.
The various media types supported along with the corresponding IEEE
802.3 and 802.3u standards and connector types are as follows:

3.2.1
The following procedure applies to installations using a PM with ST-type fiber
connectors. This procedure applies to ports using a 6K32 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.
5.
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 6K-MSC, 6K-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.

Installation and User Guide (02/05)
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 (RJ-45,CAT3, CAT5, Unshielded or Shielded)
The RJ-45 ports of the Magnum 6K32 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 cables (which work for both 10 Mb
and 100Mb) be used whenever possible in order to provide flexibility in a
mixed-speed network, since dual-speed ports are auto-sensing for either 10 and
100Mb/s.
The following procedure describes how to connect a 10BASE-T or 100BASE-
TX twisted pair segment to the RJ-45 port. The procedure is the same for both
unshielded and shielded twisted pair cables.
1. Using standard twisted pair media, insert either end of the cable with an RJ-45
plug into the RJ-45 connector of the port. Note that, even though the connector is
shielded, either unshielded or shielded cables and wiring may be used.
2. Connect the other end of the cable to the corresponding device
3. Use the LINK LED to ensure proper connectivity by noting that the LED
will be illuminated when the unit is powered and proper connection is
established
3.2.5
Connecting Twisted Pair (CAT5E or better, Unshielded or Shielded)
The RJ-45 Gigabit ports of the Magnum 6K32 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 maximum distance for unshielded twisted pair cabling is 100 meters (328
ft). See Section 4.3 for manual Up-Link switch on port 1 of copper port modules.

The following procedure describes how to connect a 1000BASE-T twisted pair segment
to the RJ-45 port. The procedure is the same for both unshielded and shielded twisted
pair cables.
1. 1000Base-T connections require that all four pairs or wires be connected. Insert
either end of the cable with an RJ-45 plug into the RJ-45 connector of the port.
Note that, even though the connector is shielded, either unshielded or shielded

Table-Top or Shelf Mounting
The Magnum 6K32 Manageable Switches can be easily mounted on a table-top
or any suitable horizontal surface, and has four rubber feet to provide stability without
scratching finished surfaces.
3.3.1
Rack-mounting (for 19” RETMA racks), regular Magnum 6K32s
Installation of a Magnum 6K32 Fiber Switch in a 19” rack is a simple
procedure. The units are 1U (1.70”) high. When properly installed, the front-mounted
LED status indicators should be in plain view and easy to read.
Rack-mount installation requires
special 19” rack-mounted brackets
and screws (included with each
Magnum 6K32 unit). These

Fig 3.3.1 Mountings for Magnum 6K32 units rack-mounted in a frame
assemblies in rack-mounting frames where the rack-mount equipment is typically
accessed in operation from both sides.
The bracket mounting holes in the sides of the Magnum 6K32 permits it to be
mounted in various ways. The same holes fit all three types (19”, ETSI, 23”) of brackets.
The mounting for the 23” is illustrated in Figure 3.3.1 below. The brackets may be
attached flush with the front, or attached in the center for a set-back mounting which may
reduce cabling torque.
The optional 23” brackets and the ETSI (21”) brackets each come as a pair in a
package, along with the necessary screws for attaching the brackets to the sides of the
Magnum Switch unit. They must be ordered as line items.
3.3.2 Rack-mounting, Reverse version of the Magnum 6K32s
The optional Reverse Magnum 6K32 Model has all of the cabling (Ethernet
cabling, power cabling and console port cabling) connectors in the rear, and the status
LEDs in the front. The status LEDs that are co-incident with the ports are still present
there, and a second or dual set of LEDs are used for status visibility in the front of the
unit, showing the same data.
There are three options of brackets available to mount in the standard 19”
frame or the 23” frame or ETSI (21”) frame. The 19” brackets are included with each
unit, the other two may be purchased if desired.

Powering the Magnum 6K32 Managed Switch
The Magnum 6K32 Switches incorporate an internal universal power supply
and have a recessed male IEC connector for the AC power cord at the left-rear. A
manual power ON-OFF switch is adjacent. A six-foot 115 VAC 60 Hz standard power
cord is supplied with each unit shipped within the United States and Canada.
The auto-ranging power supply supports installation environments where the
AC voltage is from 90 to 260 volts with a power input frequency between 47 and 63 Hz.
The 32-port units will consume over 30 watts of power typically. When connecting the
Ethernet cabling, there is no need to power down the unit. Individual segments can be
connected or disconnected without concern for AC power-related problems or damage to
the unit.
Power supply options are available to suit the 6K32 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,
See the Appendices of this manual for more details. Use an RFQ for other variations.

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 Magnum 6K32 case.
The AC or DC power input connection is in the same panel. A manual On-Off Switch for
power to the unit is not available on 6K32 units with the Alarm Contacts option, as these
two features occupy the same space in the case.
The first NC Alarm Contact (top position) 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 trigger an
alarm in the user’s monitoring system
The second (bottom position) NC Alarm Contact is held close when there is
power on the main board inside of the 6K32. 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 6K32
Switch. Useful info. about Alarm contacts:
1. There is four terminal block (1,2,3,4)provided next to AC/DC power supply
2. The top two pins (1,2) are software operated
3. The bottom two pins (3,4) are hardware operated
4. By default it is NC (normally closed)
5. The software operation need to be enable and set to get the Alarm traps. For detail
information about the Software Alarm and software control of SNMP alarm traps, please
reference the Magnum MNS-6K Software User Manual. (Chapter 19th).

6K32 Port Module (6KPM) Installation
The Magnum 6K32 Switches are normally received from the factory with 24
ports fixed and one required 6KPM modules installed. There may be situations where
6KPM cards need to be added or replaced. In cases where a 6KPM module is desired to
add in the modular slot, the faceplate for an available front-mounted slot must be
removed. The following procedure describes this operation.
3.5.1 Preparation for Installing and Removing 6KPMs
STOP!!!
Be sure the power cord is unplugged
from the chassis before attempting to remove
and/or replace any PM cards.
Failure to do so may result in damage to the unit
and will void the warranty.

Caution- Avoid Static Discharge: The port modules (like most electronic
equipment) are sensitive to static discharge. Use proper ESD measures
when handling port modules.
Step 1. Make sure the 6KPM Card package has all necessary accessories to install it
properly. Each 6KPM Card package, for field installation contains
(Daughterboard (Bigger) and Granddaughter board (smaller), three 5/8 stand
offs for Granddaughter board, six #4-40 Pan-Head screws along with Front
panel face plate package. The Front panel faceplate package includes 3 retainer
brackets and six #2-56 flat head screws.
NOTE: Every 6KPM Card package comes with their matching Daughter and
Granddaughter board. The copper 6KPM card should not work properly if
mixed with other Fiber combo 6KPM card packages. Always install the PM
module separately one by one to avoid the mixing.
Step 2. Remove Chassis Cover
The Magnum 6K32 chassis are combined with top, bottom and front panel
parts and assembled together with the help of 17 Philips-head screws. There are
5 screws located on the front-bottom and 3 at rear-top of the unit and one each
on the front and rear sides. First Remove the front panel screws (total 12) as
shown in the fig 3.5.1a after the remove. Once these are removed, the front
panel can be easily pulled out to the front. The top cover can be easily pulled
off to the front from the chassis base, as shown in the Fig. 3.4.1b. When the
chassis top cover has been removed, the interior of the unit is exposed.

NOTE:. When leaving 6KPM slots empty, always use a face plate (Magnum 6K8-
BLNK) to cover the slot opening in the front panel. This will maintain proper cooling
air flow, safety, and operation as required by FCC, CE, and other regulations.
Step 6. Now screw down the daughter board with 7 #440 screws except the last two at
the end, so that it holds the daughter board securely. The figure below shows the
top view of 6KPM card after successfully installing the 6KPM cards inside the
Magnum 6K32.

Step 7. Once the installation of granddaughter and daughter modules is done properly,
the front panel screen plates(come along with the 6K-module) need to be properly placed
on the front of the chassis cover to complete the installation process.
Step 8. Once the 6KPM cards have been installed, the chassis top cover should be
replaced by matching at the two front corners properly and slide in until it
reaches the rear end and fit properly to match the holes. Make sure the chassis
cover is aligned properly before securing the enclosure. Place the front panel
part at the end by sliding in to the front side and secure it with 12 screws as
being mentioned earlier.
NOTE (Reverse mount Model): The Reverse model require a LED Decal, (for
checking the speed, F/H, and activity status)

Step 2. Remove retaining screws placed on top for the 6KPM and Face Plate
On the top of the daughter module there are six
retaining screws for each 6KPM card. These
screws are used to secure a 6KPM card in
position (see Figure 3.5.3a). Remove the three
standoffs holding the Granddaughter board with
the chassis. The screen faceplate screws out from
the inside front of the chassis cover by loosening
the 4 screws and bracket while holding it down
firmly.
Figure 3.5.3a: Top View
- 6 retaining screws shown by arrows
Step 3. Remove 6KPM Card
Carefully and gently pull out the daughter board from the latching connectors, using both
hands, gripping the board near the latch-up connectors as shown in Fig. 3.5.3b . If the
now empty slot is to remain unused, be sure to install a 6KPM-BLNK face plate cover.
Figure 3.5.3b:
Removing a
6KPM Card
Follow the step 8 to complete the process successfully.
NOTE:1. If the modular slot has not being used and moved to other unit, the empty
slot must be covered with Blank cover, to maintain proper air-inflow inside the unit
and keep off from dust and other unavoidable substance, otherwise can cause a failure
in the Switch.
2. If the PM module in the modular slot is not being installed properly or loose in
connection, the MNS-6K management software will not boot-up properly and a error
will generate as –{ failed to read register device type (offset 0x1600) on slot “A or B or
C or D”}, whichever the slot has been used.
3. Always boot-up the Switch after any new module installation on modular slot to
confirm the successful installation, before placing the chassis cover.

OPERATION
This chapter describes the functions and operation of the Magnum 6K32
Switch.
4.1
Switching Functionality
A Magnum 6K32 provides switched connectivity at Ethernet wire-speed
among all of its ports. The Magnum 6K32 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 6K32,
but local traffic on a port will not consume any of the bandwidth on any other port.
Magnum 6K32 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 6K8-RJ45 (modular port). Optional Half / Full duplex
mode and 10 or 100Mbps selection for the switched ports must be configured through
MNS-6K software per unit as per the requirement. The internal functions of both are
described below.
Filtering and Forwarding
Each time a packet arrives on one of the switched ports, the decision is taken to
either filter or to forward the packet. Packets whose source and destination addresses are
on the same port segment will be filtered, constraining them to that one port and relieving
the rest of the network from having to process them. A packet whose destination address
is on another port segment will be forwarded to the appropriate port, and will not be sent
to the other ports where it is not needed. Traffic needed for maintaining the operation of
the network (such as occasional multi-cast packets) are being forwarded to all ports.
The Magnum 6K32 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.

Magnum 6K32 Managed Switch
Installation and User Guide (02/05)
Address Learning
All Magnum 6K32 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 6K32 Switch automatically keeps
up with node locations.
An address-aging algorithm causes least-used addresses to fall out in favor of
frequently-used addresses. To reset the address buffer, cycle power down-and-up.
4.2
Status LEDs
For all Magnum 6K32 models :
PWR
LK
ACT
F/H
: Power LED, ON when external power is applied to the unit.
: Steady ON, Link status for 10 Mbps and 100Mbps operation.
: ON with port activity for 10 Mbps and 100Mbps operation.
: 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
Up-link Cross-over Switch on RJ-45 port modules, for port#1 only
The modular slot provided on Magnum 6K32 managed switch can be filled
with 6KP8-RJ45 port module among all the multiple choices of port modules. The upper
part of the copper port module (6KP8-RJ45) has a manual Up-link switch, located on the
inside of the unit on the port module board next to the RJ45 port # 1 which it controls. It
enables the port’s cable to be cascaded (X) to a 10/100Mb repeater or switching hub in
the network. The manual Up-link switch position is configured as (=) position as default
factory setting, where used for all-copper module or combo modules.
4.4
Auto-Cross (MDIX)Auto-negotiation, for 10/100Mbps RJ-45 ports
The 24 RJ-45 ports on Magnum 6K32 supports auto-cross (MDI or MDIX) in the
auto-negotiation mode according to the IEEE 802.3u standard. No crossover cables
are needed when connecting the 6K32’s 10/100 copper ports to other unmanaged
switches, legacy hubs, managed switches, media-converters etc. Please note that
there can be conditions with managed switches where the switch manager fixes the
port settings via software, and the result of the auto-negotiation is changed in the
managed switch by the manager commands. In such cases, the 10/100 speed or the
F/H mode may be affected, but auto-cross in the 6K32 Switches will still work. The
auto-cross function can be disabled, if fixed the port at 10 or 100Mb through
software..

Magnum 6K32 Managed Switch
Installation and User Guide (02/05)
The Managed Magnum 6K32 Fast Ethernet copper ports can be set for either
fixed 100Mb speed or N-way auto-negotiation per the IEEE802.3u standard. The
selection is made via 6K-MNS software. The factory default setting is for auto-
negotiation. At 100Mb-fixed speed, the user may select half- or full-duplex mode by
6K-MNS Software for each RJ-45 port separately. For detail information see Section 8
(Optimizing Port usage) of Magnum 6K32 Software user guide (MNS-6K) . See Section
(2.2.9 at page no.14) of this manual to access the “MNS-6K Software user-guide”
One frequently-used application for the Managed 6K32 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 100Mb fixed speed. Attachment to 10/100 auto-
negotiation ports typically will not work properly. The 6K32 Switch’s RJ-45 ports
handle this situation by configuring the ports as per desire through MNS software port
settings and can check the port status of each port after the change.
When Magnum 6K32 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.
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 10
Mb 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

Magnum 6K32 Managed Switch
Installation and User Guide (02/05)
that they are in is powered up. These are exceptions to the “negotiate at
LINK – enabled” rule above, but may be occasionally encountered.
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 6K32’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.
When operating in 100Mb half-duplex mode, cable distances and hop-counts
may be limited within that collision domain. The Path Delay Value (PDV) bit-times must
account for all devices and cable lengths within that domain. For Magnum 6K32 Fast
Ethernet switched ports operating at 100Mb half-duplex, the bit time delay is 50BT.
4.5
Flow-control, IEEE 802.3x standard
Magnum 6K32 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 6K32 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 6K32 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 6K32 Switch implements a back-pressure
algorithm on 10/100 Mb ports for flow control. That is, the switch prevents frames from
entering the device by forcing a collision indication on the half-duplex ports that are
receiving. This temporary “collision” delay allows the available buffer space to improve
as the switch catches up with the traffic flow.

Power Budget Calculations for Magnum 6K32 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) = PT(min) - PR(min)
where PT = Transmitter Output Power, and PR = Receiver Sensitivity
Worst case OPB = OPB - 1dB(for LED aging) - 1dB(for insertion loss)
Worst case distance = {Worst case OPB, in dB} / [Cable Loss, in dB/Km]
where the “Cable Loss” for 62.5/125 and 50/125µm (M.m) is 2.8 dB/km,
and the “Cable Loss” for 100/140 (Multi-mode) is 3.3 dB/km,
and the “Cable Loss” for 9/125 (Single-mode) is 0.5 dB/km
and the “Cable Loss” for 9/125 (Single-mode) is 0.4 dB/km (LXSC25)
and the “Cable Loss” for 9/125 (Single-mode) is 0.25 dB/km
(LXSC40)
and the “Cable Loss” for 9/125 (Single-mode) is 0.2 dB/km (LXSC70)

* 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)

6KPM Module Description
An important feature of the Magnum 6K32 is the use of one Port
Modules for flexible mixed-media connectivity to RJ-45 and fiber media in the
modular slot. Since the Magnum 6K32 Switches have dual-speed capability for
copper ports, the 6 or 8-port interfaces are designed to support all standard
Ethernet media types at 10 or 100Mps speed. Each 6K32 PM can provide two,
four, six or eight ports for connecting Ethernet segments with its individual
connector type and media.
For a list of 6K32 Port Module types, refer to Section 1.2
Each 6K PM is individually described in the following sections.
NOTE: The port #1 on the RJ-45 ports on all the modules, either all
RJ-45 ports or used for COMBO module is set as (=) as other ports.

power source leads to the -48 VDC, 24VDC and 125VDC power terminal block on the
Magnum 6K32s. (see figure at right).
In this picture, the -48VDC terminal block on the Magnum 6K32 is located on
the rear of the unit and is equipped with three (3) screw-down lead posts. It is similar for
24VDC and 125VDC options on Magnum 6K32. The leads are identified as negative (-),
positive (+), and chassis ground (GND).
Figure B4.0: -48VDC Terminal Block on Magnum 6K32-48VDC
The actual connection procedure is very straightforward. Simply connect the
leads to the Magnum unit, beginning with ground. Ensure that each lead is securely
tightened.
Note: The GND should be hooked up first. The 6K32 unit has a floating ground, so the
user may elect to Ground either + or = terminal to suit the customer’s use.
Before connecting hot lines to the Terminal Block of –48VDC, 24VDC or
125VDC, 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 “+”.
An ON-OFF manual switch is optional for DC power. This can be used to cut
off power connections and as a RESET for the Magnum 6K32 Switch.

Installation and User Guide (02/05)
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, 24VDC and
125VDC dual source leads to the -48VDC, 24VDC 7 125VDC power terminal block on

Dual Source terminal block for the 24VDC and 125VDC are similar.
Figure C5.0: -48VDC Dual-Source, wiring connections to the External
Terminal Block on a Magnum 48VDC with Dual-Source option
Note: The GND should be hooked up first. The6K32 unit has a floating ground, so the
user may elect to Ground either + or = terminal to suit the customer’s use.
Before connecting hot lines to the Terminal Block of –48VDC, 24VDC or
125VDC, 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 “+”.
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.
