Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05)

2.2 Product Description - Magnum 6K32T Managed Switch

The Magnum 6K32T 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 of various media requirements of copper and Fiber.

Being a member of the Magnum 6K-family, the Magnum 6K32T supports modularity in the last two slots to configure any of the modules offered. The Magnum 6K32T comes along with 16 10/100 RJ-45 ports fixed and two modular configuration slots. The two modular configurable slots of the Magnum 6K32T provide the flexibility to configure up to sixteen RJ-45 and 16 fiber ports for a maximum of 16+ 4 Gigabit(1000Mb) options to handle high bandwidth application. The Magnum 6K32T supports the modularity in the last two slots, to configure any of the modules offered.

The Magnum 6K32T is equipped with robust 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, LinkLoss-Learn, STP and RSTP. Security features include SNMPv3, SSL/SSH, 802.1X, TACACS+, Port Security, and Tagged VLANs. See MNS-6K materials for further details about software.

The Magnum 6K32T‘s port flexibility is achieved via a family of 6K port modules (6KPM). These modules come with copper and fiber-built-in (emphasizing Small Form Factor fiber for high fiber port density), 6-port modules for fiber and RJ-45 combinations, and 1Gb or 2Gb port module selections using GBIC transceivers in copper or fiber. These modules can be factory configured in a base chassis unit (or may be changed in the field by trained technicians) to adapt the unit to the user’s application and Ethernet media requirements. Evolving mixed-media requirements for 10Mb and 100Mb fiber, copper, and Gigabit ports can be easily handled by the Magnum 6K32T product reliably

The packaging and power-input options target the Magnum 6K32T for heavyduty 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

www GarrettCom com

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05) 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 6K32T provides high performance plug-and-play hardware operation, 802.1p packet prioritization in hardware, and industry-standard managed networks software functionality, all in convenient 1U rack-mount packages.

2.2.1a Magnum 6K32T Chassis

The Magnum 6K32T 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 a large selection of fiber and copper port types and combinations of types. Typically the configuration is eight port modules 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 modules can be chosen. The modular slot may be configured with a Gb module that accepts GBICs. The port types configurable using the modular slots allows the 6K32T to efficiently serve a large variety of applications, even those using some fiber media. The Magnum 6K32T 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.

The options can be RJ-45 or fiber media, 10 or 100 or 1000Mb copper or Fiber, or Small Form Factor options to provide more fiber ports. The two modular slots can be configure with maximum of four Gigabit modules as shown below.

Figure 2.2.1b: 6K32T front view, configured for16 RJ-45 ports +2 Modular slot with Dual Giga module.

The Magnum 6K32T was designed for heavy duty Carrier class and Industrial

applications that require high port density and secure devices which save in cost and rack space to provide reliable solutions. This rack mountable managed switch comes with a wide variety of DC/AC options. Software includes MNS-6K with support for modular ports.

The modular option with two slots explores this managed switch’s extra capability to meet any 10 or 100 or Gigabit requirement effectively satisfying any demand for complex Ethernet. The Triple Play demand of bandwidth to meet “voicedata-video” over Ethernet will be handled efficiently by this managed switch and will play an effective role in providing modularity to the solution.

The growing demand of security and “Ease of use” are the other adding features of this new managed switch. The switch allows the users to secure their network through port security, Radius X, Tacacs+ and Snmpv3 and provide an effective solution of ease of use through “Secure Web based management and scripts feature to manage the 6K32T switch remotely”. The 6K32T loaded with robust MNS-6K firmware is specially designed to meet the future demand of Ethernet requirement with cost-effective secure solutions. The Magnum 6K32T is also available in a Reverse model option, where the LEDs are on the front and the available ports along with the power supply area found on the rear side. This configuration is mostly used for carrier-class market.

The modules which may be configured and used in the modular slots of the Magnum 6K32T are described here.

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

The Magnum 6K32T 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’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 Switch detects that its free buffer queue space is low, the Switch sends industry standard (full-duplex only) PAUSE packets out to the

www GarrettCom com

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05) 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 6K32T 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

Magnum 6K32T come with licensed MNS-6K Firmware (Rel 3.2), which allows the configuration of the Magnum 6Ks as a Managed Switch and other Software enabled features.

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 switching hardware supports QoS, giving packet processing

priority to priority tagged packets according to the IEEE 802.1p standard. For portand application-specific priorities, the QoS software may be configured by the user.

 Features Fiber-Built-In

Magnum 6K32T 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 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.

2.4 Applications

Magnum 6K32T 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 also offers MNS-6K management software. Magnum 6K32T Switches are used in a variety of applications including Carrier-class (Telco) settings, client/server computing areas, secure VLAN- performance upgrades to departmental networks, and LAN traffic centers that require Gigabit backbone services. The performance characteristic of the 6K32T 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.

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

www GarrettCom com

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05)

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.

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

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 50

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 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 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 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 Twisted Pair (CAT 5) 100BASE-TX 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

www GarrettCom com

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05)

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

The RJ-45 1000BASE-TX Gigabit ports of the Magnum 6K32T 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).

Media

IEEE Standard Connector

Twisted Pair (CAT-5e) 1000BASE-T RJ-45

NOTE : It is recommended that high quality CAT-5e cables (which work for both 100

Mb and 1000Mb) be used whenever possible in order to provide flexibility in a

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 Power Budget Calculations for Magnum 6K32T 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

(min) - PR(min)

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 50/125

m (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)

The following data has been collected from component manufacturer’s (Agilent’s and Lucent’) web sites and catalogs to provide guidance to network designers and installers.

Fig 3.3.1 Dual Side-Mountings for Magnum 6K32T units

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 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.

3.3.2 Rack-mounting, Reverse

(Not available as of October 2005) The optional Reverse Magnum 6K32T 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 coincident 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, 23” frame, or ETSI (21”) frame. The 19” brackets are included with each unit, the 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 Managed Switch

The Magnum 6K32T 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 6K32T Switches to special highavailability 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’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 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 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 6K32T. 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 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

www GarrettCom com

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05)

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 Port Module (6KPM) Installation

The Magnum 6K32T 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 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 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: 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

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.

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05)

Step 2. Remove Chassis Cover

The Magnum 6K32T 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.

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 6K32T.

Fig. 3.5.2g Top View : 6KPM Module installed inside a 6K32T Switch

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.

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05) 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.

3.5.3 Removing 6KPM Cards

To properly remove a 6KPM card from the 6K32T Managed Switch, follow the

3 steps below.

Step 1. Remove chassis cover See procedures in Section 3.5.1 above.

Caution: Be sure the power cord is unplugged.

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.

3.6 Connecting the Console Terminal to Magnum 6K32T (Management)

Use a DB-9 “null modem” cable to connect the Magnum 6K32T Console Port (the RS-232 port on the 6K32T Switch) to the your PC, so that your PC becomes the 6K32T’s Console Terminal.

4.0 OPERATION

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

4.1 Switching Functionality

A Magnum 6K32T provides switched connectivity at Ethernet wire-speed

among all of its ports. The Magnum 6K32T 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

www GarrettCom com

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05) 6K32T, but local traffic on a port will not consume any of the bandwidth on any other

port.

Magnum 6K32T 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 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 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 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 6K32T 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

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05)

4.3 Up-link Cross-over Switch on RJ-45 port modules, for port#1 only

The modular slot provided on Magnum 6K32T 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 6K32T 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 6K32T’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 6K32T 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 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 autonegotiation. 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 7 (Port Setup) of Magnum 6K32T Software user guide (MNS-6K) . See Section (2.2.9 at page no.13) of this manual to access the “MNS-6K Software user-guide”

One frequently-used application for the Managed 6K32T 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-

www GarrettCom com

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05) negotiation ports typically will not work properly. The 6K32T 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 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

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’s RJ-45 ports will try to detect its idle signal to determine 10 or 100 speed, and will default to halfduplex 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 Fast Ethernet switched ports operating at 100Mb half-duplex, the bit time delay is 50BT.

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05)

4.5 Flow-control, IEEE 802.3x standard

Magnum 6K32T 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 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 Switch port for sufficient time to let the Switch reduce the buffer space used. When the available freebuffer 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 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.

5.0 Magnum 6K32T Managed Switch Port Modules

This chapter describes each Port Module (PM), including appearance,

functionality, and status displays.

5.1 Inspecting the Package and Product

5.2 6KPM Module Description

An important feature of the Magnum 6K32T 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 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 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 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.

Form Factor

Magnum 6KP8-MLC is a eight-port multi-

mode fiber LC connector “small-form-factor” used primarily in 100Mbps fiber-to-thedesktop links. When installed in a Magnum 6K32T Switch, it supports fiber optic cable distances up to the IEEE-standard 100Mbps distance limits, i.e., typically 2km at full-duplex and

412m at half-duplex.

The compact size of the LC Connector reduces the size of wiring panels in

wiring closets while providing the advantage of “future-proof” fiber optic technology.

The cable end is a “plug-in” connector with both fiber strands terminated in one housing that cannot be improperly inserted. Each port has an Activity (ACT) LED indicating packets being received, a Link (LK) LED indicating proper connectivity with the remote device when lit, and a FDX/HDX LED indicating full-duplex mode when lit (or half-duplex when off).

B3.0 APPLICATIONS FOR DC POWERED SWITCHES

Magnum 6K32T Fiber Switches are easily installed in a variety of applications where -48VDC, 24VDC and 125VDC power is used as the primary power source. The48VDC, 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.

C2.0 MAGNUM 6K32T & 6K32, with -48VDC, 24VDC and 125VDC DualSource option

The 6K32T & 6K32-Switch models with the internal -48VDC, 24VDC and 125VDC Dual-Source power supply are designed for installations where a battery plant is the power source, and where two separate power sources are utilized in order to increase operational uptime and to simplify maintenance.

The functionality of the Magnum 6K32T Switch -48VDC, 24VDC and

125VDC Dual-Source Option units is identical to the standard AC-powered models. Refer to the main sections of this Installation and User Guide for a detailed description of the Magnum 6K32T Switches.

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

FUSE

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

www GarrettCom com

Magnum 6K32 & 6K32T Managed Switch Installation and User Guide (12/05)

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 the Magnum 6Ks Switch (shown in Figure ) The -48VDC terminal block on the Magnum 6K32T Switch, as shown in Fig C5.0 is located on the right rear of the unit and is equipped with five (5) screw-down

Terminal Block on a Magnum 48VDC with Dual-Source option

Note: The GND should be hooked up first. The6K32T 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. The 24VDC and 125VDC terminal block on Magnum 6K32T & 6K32’s is similar to that described in the –48VDC information above.
