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).

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

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.

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.

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

Another feature implemented in Magnum 6K32T & 6K32TRC 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.

2.2.9 Managed Network Software (MNS-6K) for Magnum 6K32T &
6K32TRC

2.3 Features and Benefits

 Managed switching for high performance Ethernet LANs
Magnum 6K32T & 6K32TRC & 6K32TRC 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 two Gigabit ports for backbone connections where managed
network services are desired.

 Switching services includes 802.1p QoS packet prioritization
The Magnum 6K32T & 6K32TRC 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 6K32T & 6K32TRC Managed Switches are designed with modular slots to

naturally include fiber ports and support mixes of the following; multi-mode and
single-mode; 10 Mb, 100Mb and 1000Mb speed; full-and half-duplex; and 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 6K32T & 6K32TRC 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

2.4 Applications

Magnum 6K32T & 6K32TRC Fiber Switches offer high performance along
with one or two modular slot options to fulfill the choice of copper/Fiber, 10,100 or
1000Mb requirements. The 6K32T & 6K32TRC also offers MNS-6K management
software loaded with multiple useful features. The Magnum IEC61850 6K32T &
6K32TRC Switches are used in a variety of Power sub-stations applications including,
Industrials and temp. un-controlled, secure VLAN- performance upgrades to
departmental networks, and LAN traffic centers that require Gigabit backbone services.
The performance characteristic of the 6K32T & 6K32TRC Switches enables them to
inter-connect a series of subnets (one subnet per 6K32T 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 the modular slot is ideal for upgrading existing
Ethernet LAN networks where existing cabling must be accommodated. The fiber-built­in media capability provides future-proof fiber cabling for the LAN structure. The
secured management features offer a multiple options to provide a secure Network
solution.

Example 1 : Magnum 6K32T Switch for a VLAN application

Equipped with lots of advanced management features, the Magnum 6K32T

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 6K32T’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 each keep a secure LAN, the 6K32T’s VLAN feature will
prevent traffic cross-over among traffic domains and thus keep sensitive data and
information controlled. The Managed Magnum 6K32T equipped with VLAN capability
is ideal for any application where a secure VLAN to multiple departments is needed.

The modularity of the 6K32T 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 6K32T 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 6K32T 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 backbone 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 data­mining 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.

Magnum 6K32T & 6K32TRC Managed Switch Installation and User Guide 05/07)
The Magnum 6K32T Managed Switch equipped with copper and optional dual Gigabit
fiber ports on modular slots provide an economical and seamless solution to the
requirements. The user-configurable Magnum 6K32T 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 6K32T Managed Switch with NEBS Level 3 compliance and management
flexibility allows the user more than one configuration alternative. The user has an
advantage by fulfilling the present requirements as well as benefiting from the multiple
choices of modules to support future expansion as the network evolves. The dual Gigabit
port option in the modular slot boosts the bandwidth for high speed to support the peak
traffic and minimize congestion.

Example 3 Redundant Application (6K32TRC)

In a redundant application for high network availability where a rack­mountable managed switch with over 24 ports is required with dense port features,
Magnum 6K32T’s equipped with redundant LAN features like S-Ring, RSTP, Link­Loss-Learn and various security features are easily qualified for the application. The ­48VDC input power option with Dual Source is especially useful in telecom central
offices.
The Magnum 6K32T with two Gigabit ports in the modular slot allows it to
connect into a Gigabit mesh structure with an RSTP and S-Ring combination used in a
no-single-point-of-failure self-healing LAN topology along with a ring of multiple 6K25s
at the edge to allow the system to efficiently recover from a fault in the network.
industry standard Rapid Spanning Tree Protocol 802.1d is used in the 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.

The

A redundant LAN setup not only provides a reliable recovery solution from
network faults, but also improves operating up-time to simplify maintenance, save
money and recover valuable time. In a critical application where secure data has been
stored in a data mining storage facility, a redundant network provides a more secure
solution.

The figure below has Magnum 6K32T’s and 6K25’s connected over the gigabit mesh
structure for a high bandwidth secure redundant LAN setup.

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 55C FOR 6K32T and 60C for 6K32TRC.

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 load unevenly or
overload 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.

6.)

24vdc, -48vdc, and 125vdc must be installed in restricted
access locations.

7.)

CB-Circuit breaker of 10Amps should shown on top of Rack.

This section describes installation of the Magnum 6K32T Switches, as well as
connection of the various Ethernet media types.

3.1 Locating Magnum 6K32T Switches

The location of a Magnum 6K32T 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 6K32T site. The
rugged metal case of the Magnum 6K32T 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.

3.2 Connecting Ethernet Media

The Magnum 6K32T & 6K32TRC 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 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 6K32T & 6K32TRC 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 the cable is connected, the normal cause is improper cable polarity.
Swap the fiber cables at the PM connector to try to remedy this situation.

3.2.2 Connecting Fiber Optic SC-type

The following procedure applies to installations using a PM with SC-type fiber
connectors, i.e., using 6K-MSC or 6K-SSC (single mode) etc.
When connecting fiber media to SC connectors, simply snap the two square male
connectors into the SC female jacks of the 6KPM until they click and are secure.

, "Snap-In"

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 procedure 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 6K32T & 6K32TRC 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).

Media

IEEE Standard Connector

Twisted Pair (CAT 3, 4, 5) 10BASE-T RJ-45

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 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 6K32. 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 6K32 passes the 1613specifications
for zero packet loss with fiber ports & with RJ45 ports used as indicated here.

3.2.5 Connecting Twisted Pair (CAT-5e or better, Unshielded or Shielded)

The RJ-45 1000BASE-TX Gigabit ports of the Magnum 6K32T & 6K32TRC
can be connected via copper media with the following minimum specifications;
1000BASE-T, CAT-5e, or for better results, 100-ohm UTP shielded twisted pair (STP)
balanced cable. The CAT-5e or the more effective 100-ohm UTP shielded twisted pair
(STP) balanced cable is recommended when making 1000BASE-TX connections. In
either case, the maximum distance for unshielded twisted pair cabling is 100 meters (328
ft).

mixed-speed network.

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
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

3.2.6 Gigabit SFP (Small Form-factor Pluggable) Optical Transceivers

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.).

3.2.7 Power Budget Calculations for Magnum 6K32T & 6K32TRC 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
where P

= Transmitter Output Power, and PR = Receiver Sensitivity

T

(min) - PR(min)

T

Worst case OPB = OPB - 1dB(for LED aging) - 1dB(for insertion loss)

industry where they are a standard for Central Office rack-mounting purposes. The 23”
and the ETSI brackets are mainly used for larger equipment

These brackets are rack-mounted in a frame typically accessed in operation from both
sides.

The bracket mounting holes in the sides of the Magnum 6K32T & 6K32TRC
permits it to be mounted in various ways. The same holes fit all three types (19”, ETSI,
and 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 separate line items.

other two may be purchased as separate options.

With each bracket type, there are three different mounting options as shown in Fig. 3.3.2.
The case of the Magnum 6K32T has mounting holes prepared for each of the mounting
arrangements. Users may choose the mounting arrangement most suitable for their
installation.

3.4 Powering the Magnum 6K32T & 6K32TRC Managed Switch

The Magnum 6K32T & 6K32TRC Switches incorporate an internal universal
power supply and have a recessed male IEC connector for the AC power cord at the left­rear. 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 6K32T & 6K32TRC 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.

3.4.1 Alarm Contacts for monitoring internal power, and Software Traps

The Alarm Contacts feature, optional on Magnum 6K32T & 6K32TRC’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 Magnum
6K32T & 6K32TRC 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 6K32T & 6K32TRC 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

www GarrettCom com

..

36

Magnum 6K32T & 6K32TRC Managed Switch Installation and User Guide 05/07)
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 6K32T & 6K32TRC. 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 6K32T & 6K32TRC 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 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 19th).

3.5 6K32T & 6K32TRC Port Module (6KPM) Installation

The Magnum 6K32T & 6K32TRC Switches are normally received from the
factory with 24 ports fixed and one required 6KPM module installed. There may be
situations where 6KPM cards need to be added or replaced. In cases where a 6KPM
module needs to be added in the modular slot, the faceplate for an available front­mounted 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 and connections

for all powers single or dual, 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: Opening of the 6K32TRC chassis can only be

performed by trained service persons. 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 the Granddaughter board, six #4-40 Pan-Head screws along with a

37

www GarrettCom com

..

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

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.

NOTE for Power Substations

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 packet-

Step 2. Remove Chassis Cover

The Magnum 6K32T & 6K32TRC 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. 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.

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

4.0 OPERATION

This chapter describes the functions and operation of the Magnum 6K32T &
6K32TRC Switch.

4.1 Switching Functionality

A Magnum 6K32T & 6K32TRC provides switched connectivity at Ethernet

wire-speed among all of its ports. The Magnum 6K32T & 6K32TRC support 10/100Mbs
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 6K32T & 6K32TRC, but local traffic on a port will not consume any
of the bandwidth on any other port.

Magnum 6K32T & 6K32TRC 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 6K32T & 6K32TRC 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 6K32T & 6K32TRC 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 6K32T & 6K32TRC Switch
automatically keeps up with node locations.

www GarrettCom com

..

46

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

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 6K32T & 6K32TRC models :

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)Auto-negotiation, for 10/100Mbps RJ-45 ports

The 24 RJ-45 ports on Magnum 6K32T & 6K32TRC support 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 6K32T & 6K32TRC’s 10/100
copper ports to other unmanaged switches, legacy hubs, managed switches, media­converters 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
6K32T & 6K32TRC Switches will still work. The auto-cross function can be
disabled, if fixed the port at 10 or 100Mb through software..

The Managed Magnum 6K32T & 6K32TRC 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 full­duplex mode by 6K-MNS Software for each RJ-45 port separately. For detail
information see Section 7 (Port Setup) of Magnum 6K32T & 6K32TRC
Software user guide (MNS-6K) . One frequently-used application for the Managed
6K32T & 6K32TRC 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

47

www GarrettCom com

..

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

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 auto­negotiation ports typically will not work properly. The 6K32T & 6K32TRC
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 6K32T & 6K32TRC RJ-45 copper ports are set for auto­negotiation 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

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 auto­negotiation 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 6K32T & 6K32TRC’s

48

www GarrettCom com

..

Magnum 6K32T & 6K32TRC Managed Switch Installation and User Guide 05/07)
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 6K32T &
6K32TRC Fast Ethernet switched ports operating at 100Mb half-duplex, the bit time
delay is 50BT.

4.4 Flow-control, IEEE 802.3x standard

Magnum 6K32T & 6K32TRC 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 6K32T & 6K32TRC 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 6K32T
& 6K32TRC 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 6K32T & 6K32TRC Switch implements a back­pressure 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.

5.2 6KPM Module Description

An important feature of the Magnum 6K32T & 6K32TRC 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 6K32T & 6K32TRC 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 6K32T & 6K32TRC PM can provide two, four, six or eight ports for
connecting Ethernet segments with its individual connector type and media.

For a list of 6K32T & 6K32TRC Port Module types, refer to Section 1.2

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).

Important 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 RJ­45 device and eliminate the use of cross-over cable.

The RJ-45 pins normally (TP crossover switch) are per the standard for hubs-to­users twisted pair wiring: 1 = receive+, 2 = receive-, 3 = transmit+, 6 = transmit-,
other pins not used. When the TP crossover push-button is UP, the pins of the RJ­45 port are per the standard for up-links using twisted pair wiring, i.e., the transmit
and the receive pairs are exchanged: 1 = transmit+, 2 = transmit-, 3 = receive+, 6 =
receive-, other pins not used.

NOTE: for Power Substations

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 6K32. 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 6K32 passes the 1613specifications

for zero packet loss with fiber ports & with RJ45 ports used as indicated here.

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 8 RJ-45 ports with PD devices connected (up to

15 watts per PoE port).

 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.

B3.0 APPLICATIONS FOR DC POWERED SWITCHES

Magnum 6K32T & 6K32TRC Fiber Switches are easily installed in a variety of
applications where -48VDC, 24VDC and 125VDC power is used as the primary power
source. The- 48VDC, 24VDC and 125VDC power configuration provides an Ethernet
networking solution utilizing a special power supply in a Managed Switch.
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 24VDC and 125VDC solution are particularly useful in the Industrial
environment, where it is common facilities to operate on 24VDC or 125VDC power. The
125VDC solution is mainly used in power utilities, such as electrical substations,
electrical generating plants, etc. The 24VDC applications are mainly in the Industrial
environment, such as factory floor, HVAC equipment, military equipment, etc.

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 6K32T & 6K32TRC 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 6K32T & 6K32TRC Switch.

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, 24VDC and
125VDC dual source leads to the -48VDC, 24VDC 7 125VDC power terminal block on
