1.4 Firmware Overview

1.4.1 Command Line Firmware

Commands typed by the user will be shown in the following color and font.

command

The MultiLink Switch Software prompt will be shown in bold and fixed-width text, with a #

> character at the end. The default prompt is indicated as follows:

ML3000#

The following hold for syntax rules:

• Syntax rules are italicized

• The command part is in bold

• Optional entries are shown in [square brackets]

• Parameter values within are shown in <pointed brackets>

• Optional parameter values are shown again in [square brackets]

Thus, the syntax

command [parameter1=<value1>[,paramter2=<value2>]] parameter3=<value3|value4>

indicates the following:

• parameters 1 and 2 are optional

• parameter 2 can be used optionally only if parameter 1 is specified

• parameter 3 is mandatory.

1.4.2 EnerVista Software

Whenever the word PC is used, it implies a UNIX, Linux, Windows, or any other operating system based workstation, computer, personal computer, laptop, notebook or any other computing device. Most of the manual uses Windows XP based examples. While effort has been made to indicate other operating system interactions, it is best to use a Windows-XP based machine when in doubt.

The documentation reflects features of MultiLink Switch Software version 1.7.x or later. If your switch is not at the current version, GE Multilin recommends upgrade to version 1.7.x or later. Please refer to the GE Multilin website for information on upgrading the MultiLink Switch Software.

Icons common to the EnerVista MultiLink Secure Web Management (SWM) firmware for edit, delete, save and refresh are:

• Edit - edit the values

• Delete - delete the current row or the value(s)

• Save - save configuration changes

• Refresh - repaint the screen

INTRODUCTION CHAPTER 1: INTRODUCTION

1.4.3 Before Starting

This section explains how to setup the GE MultiLink family of switches using the console port on the switch. Some of the functionality includes setting up the IP address of the switch, securing the switch with a user name and password, setting up VLANs and more.

Before you start, it is recommended to acquire the hardware listed below and be ready with the items listed.

For initial configuration through the serial/console port:

1. A female-female null modem cable.

2. A serial port. If your PC does not have a serial port, you may want to invest in a USB-to-serial converter or USB-to-serial cable.

3. Terminal emulation firmware such as HyperTerminal or other equivalent firmware. Ensure the firmware supports Xmodem protocol, as you may need this in the future to update the MultiLink Switch Software.

4. Enough disk space to store and retrieve the configuration files as well as copy firmware files. We recommend at least 15 MB of disk space for this purpose.

5. For access security - decide on a manager level account name and password

6. IP address, netmask, default gateway for the switch being configured.

As a default, the switch has no IP (Internet Protocol) address and subnet mask. For first time use, the IP address has to be assigned. This can only be done by using the console interface provided.

The same procedure can also be used for other configuration changes or updates (for example, changing the IP address, VLAN assignments and more). Once the IP address is assigned and a PC is networked to the switch, the switch's command line interface (CLI) can be accessed via telnet. To manage the switch through in-band (networked) access (e.g. telnet, or web browser Interface), you should configure the switch with an IP address and subnet mask compatible with your network. Also, change the manager password to control access privileges from the console.

Many other features such as optimizing the switch's performance, traffic engineering and traffic prioritizing, VLAN configuration, and improving network security can be configured through the switch's console interface as well as in-band (networked) access, once the IP address is setup. Besides the IP address, setting up the SNMP parameters allows configuration and monitoring through an SNMP network management station running a network management program.

CHAPTER 1: INTRODUCTION INTRODUCTION

1.5 Command Line Interface Firmware

1.5.1 Console Connection

The connection to the console is accessed through the DB-9 RJ45connector on the switch marked as the console port. This command line interface (or CLI) provides access to the switch commands. It can be accessed by attaching a PC running terminal emulation firmware to the console port.

USB-to-RJ45 adapters are also available for computers that have access to USB ports. The interface through the console or the console management interface (or CMI) enables

you to reconfigure the switch and to monitor switch status and performance.

Note

1.5.2 Console Setup

Once the switch is configured with an IP address, the command line interface (or CLI) is also accessible using telnet as well as the serial port. Access to the switch can be either through the console interface or remotely over the network. Simultaneous access (that is, through the console port as well as through the network) to the MultiLink switch is not permitted.

The Command Line Interface (CLI) enables local or remote unit installation and maintenance. The MultiLink family of switches provides a set of system commands which allow effective monitoring, configuration and debugging of the devices on the network.

Connect the console port on the switch to the serial port on the computer using the serial cable listed above. The settings for the HyperTerminal firmware are shown below. Make sure the serial parameters are set as shown (or bps = 38400, data bits = 8, parity = none, stop bits = 1, flow control = none).

FIGURE 1–1: Serial Settings in HyperTerminal

1.5.3 Console Screen

Once the console cable is connected to the PC and the firmware configured, ML3000 legal disclaimers and other text scrolls by on the screen.

INTRODUCTION CHAPTER 1: INTRODUCTION

NOTE

The line interface prompt appears displaying the switch model number (e.g. ML3000>) The switch has three modes of operation: operator (least privilege), manager, and

configuration. The prompts for the switches change as the switch changes modes from operator to manager to configuration. The prompts are shown below with a brief description.

• ML3000>

Operator Level - for running operations queries

• ML3000#

Manager Level - for setting and reviewing commands

• ML3000##

Configuration Level - for changing the switch parameter values

For additional information on default users, user levels and more, refer to User Management on page 1–15.

1.5.4 Logging In for the First Time

For the first time, use the default user name and passwords assigned by GE. They are:

•Username: manager Password: manager

•Username: operator Password: operator

We recommend you login as manager for the first time to set up the IP address as well as change user passwords or create new users.

1.5.5 Automatic IP Address Configuration

The ML3000 is operational immediately after it is powered up. The advanced management and configuration capabilities of the ML3000 allows you to easily configure, manage, and secure your devices and network.

Before starting, ensure you have the following items:

• RJ45 Ethernet cable

•PC with an Ethernet port

• Microsoft Internet Explorer 6.0 or higher

• Macromedia Flash Player 5.0 or higher (available from http://

www.macromedia.com/shockwave/download/ download.cgi?P1_Prod_Version=ShockwaveFlash)

Ensure both firmware components are installed before proceeding. The ML3000 can search the network for commonly used services that can issue an IP

address. If the switch is connected to a network, the ML3000 uses the following process to find an IP address.

Note

If the ML3000 is not connected to a network, then proceed to Step 3 below. or use the default IP address.

Step 1:

The ML3000 will scan the network for a DHCP server. If the server responds, the ML3000 will acquire and set the assigned IP address. To manage the switch, determine the assigned IP address and enter as follows in Internet Explorer:

1–12 MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL

CHAPTER 1: INTRODUCTION INTRODUCTION

https://<assigned_IP_address>

Ensure that https is entered, not http, and that there is connectivity (that is, you can ping the switch).

tep 2:

If there is no response from a DCHP server, the ML3000 will query for a BOOTP server. If the server responds, the ML3000 will acquire and set the assigned IP address. To manage the switch, determine the assigned IP address and enter as follows in Internet Explorer:

<assigned_IP_address>

https://

Ensure that https is entered, not http, and that there is connectivity (that is, you can ping the switch).

Step 3:

If there is no response from either a DCHP or BOOTP server, or if the switch is not connected to a network, the switch will assign itself an IP address. The ML3000 will check to see if IP address 192.168.1.2, with a network mask of 255.255.255.0, is free. If so, it will assume these values. If this IP address is assigned to another device, the ML3000 will repeat steps 1 through 3 to find a DCHP or BOOTP server or wait for the 192.168.1.2 address to become free.

Once connected, the browser will display a login prompt. The default login is:

•Username: manager Password: manager

1.5.6 Setting the IP Parameters

To setup the switch, the IP address and other relevant TCP/IP parameters have to be specified.

The IP address on the MultiLink switch is set to 192.168.1.2 from the factory. The switch is fully operational as a Layer 2 switch as a default. Setting a default IP address can potentially cause duplicate IP address problem if multiple switches are powered on and installed on the network. To manage the switch, an IP address has to be programmed.

Before starting, please ensure that the IP address assigned to the switch is known or contact your system/network administrator to get the IP address information. Follow the steps listed below to configure the switch.

 Ensure the power is off.

 Follow the steps described above for connecting the console cable

and setting the console firmware.

 Power on the switch.

 Once the login prompt appears, login as manager using default

password (manager).

 Configure the IP address, network mask and default gateway as per

the IP addressing scheme for your network.

 Set the manager password (this step is recommended; refer to the

following section).

 Save the settings (without saving, the changes made will be lost).

 Power off the switch (or a firmware reboot as discussed below).

 Power on the switch - login with the new login name and password.

Product Description

2.1 Overview

2.1.1 Introduction to the ML3000

The Multilink ML3000 Ethernet Switch provides rack-mount space efficiency and advanced port configurability for heavy duty industrial applications where maximum fiber port count and diversity are required. New advanced thermal design techniques (patent pending) enable the ML3000 to deliver high reliability and configurability even at extended operating temperatures. Special rack-mount cooling features include Thermal Fins for extra heat dissipation and internal heat transfer techniques that use the case as a heat sink. Cooler operation of internal electronic components leads to longer life-time and increased reliability.

Next-Generation industrial switch features, especially for power utility facilities in the Smart Grid, importantly include high precision IEEE 1588v2 timing synchronization with precision as low as single-digit nanoseconds. The ML3000 provides an advanced level of 1588v2 timing features and accuracy, using integrated hardware and software. Advanced timing is supported on 100 Mb and Gb ports, and is configurable on both fiber and copper port types.

The ten port slots in the ML3000 provide the configuration flexibility for network designers to choose up-to four fiber or copper Gb ports, and up-to thirty-two 100 Mb SFF fiber or copper ports. Copper ports can optionally be Power-Sourcing PoE. Modules may be configured for regular port types: PoE, IEEE 1588v2 Timing, or combinations.

ML3000 Managed Switches come with field-proven Management Software. Management Software features include LAN software support including SNMP management, IPv6, Secure Web Management, IGMP, graphical user interface (GUI), redundant LANs support, and many network management security and ease-of-use features.

ML3000 Managed Switches have rugged metal cases for regular or“Reverse” rackmounting, and auto-ranging power supplies for operation with standard AC power worldwide, or DC power input choices. Moisture and corrosion-protecting Conformal Coating is optional.

PRODUCT DESCRIPTION CHAPTER 2: PRODUCT DESCRIPTION

NOTE

2.2.2 Module A (100Mb) - four RJ45 ports (use in Slots 3-10)

The Module A four-port copper module provides four 10/100Mb switched RJ-45 ports. The 10/100Mb switched ports normally (as a default setting) are independently N-way autonegotiating and auto-crossover (MDIX) for operation at 10 or 100Mb speed in full- or halfduplex mode. (i.e., each independently selects a mode and speed to match the device at the other end of the twisted pair cable).

FIGURE 2–2: Module A, 100 Mb - four RJ45 ports

For auto-negotiation and MDIX details, see Section 4.1.6. There are two LEDs per RJ-45 port on the module; one for Link/Activity and one for F/H

Duplex. For the Module A LED designations, see Section 2.2.1: ML3000 Module LED designations.

A twisted pair cable must be connected into an RJ-45 port and the Link (L/A) indicator for that port must be ON (indicating there is a powered-up device at the other end of the cable) in order for the L/A LED to provide valid indications of operating conditions on that port.

Using the Multilink ML3000 software, the user may disable auto-negotiation and fix the desired operation of each RJ-45 port. The user may select 10Mb or 100Mb speed and fullor half-duplex mode per-port as required.

A module similar to Module A is also available with IEEE 1588v2 Timing Synchronization as Module P.

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 6.5 ft) to the 10KT. It is not recommended to use these ports in substation applications to interface to field devices across distances which could produce high (greater than 2500 V ) levels of ground potential rise (GPR) during lineto-ground fault conditions.

PRODUCT DESCRIPTION CHAPTER 2: PRODUCT DESCRIPTION

2.3 Features and Benefits

2.3.1 Packet Prioritization, 802.1p QoS

Quality of Service (QoS) means providing consistent predictable data delivery to users from datagram paths that go all across a network. As a LAN device, the ML3000 can do its part to prevent any QoS degradation while it is handling Ethernet traffic through its ports and internal switch buffers.

The ML3000 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 ML3000 software 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.

2.3.2 Frame Buffering and Flow Control

The ML3000 is a store-and-forward switch. Each frame (or packet) is loaded into the switch's memory and inspected before forwarding can occur. This technique ensures that all forwarded frames are of a valid length and have the correct CRC, i.e., are good packets. This eliminates the propagation of bad packets, enabling all of the available bandwidth to be used for valid information.

While other switching technologies (such as “cut-through” or “express”) impose minimal frame latency, they will also permit bad frames to propagate out to the Ethernet segments connected. The “cut-through” technique permits collision fragment frames (which are a result of late collisions) to be forwarded which add to the network traffic. Since there is no way to filter frames with a bad CRC (the entire frame must be present in order for CRC to be calculated), the result of indiscriminate cut-through forwarding is greater traffic congestion, especially at peak activity. Since collisions and bad packets are more likely when traffic is heavy, the result of store-and-forward operation is that more bandwidth is available for good packets when the traffic load is greatest.

When the ML3000 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. This flow-control sequence occurs in a small fraction of a second and is transparent to an observer.

Another feature implemented in the ML3000 is a collision-based flow-control mechanism (when operating at 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 in order to stop incoming traffic.

2.3.3 MultiLink Switch Software

The ML3000 includes licensed software, allowing configuration of the ML3000 as a managed switch.

All software information, including new releases and upgrades, can be accessed and download from the GE website at http://www.gedigitalenergy.com

2–8 MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL

CHAPTER 2: PRODUCT DESCRIPTION PRODUCT DESCRIPTION

2.3.4 Redundant Power Supply

With the redundant power supply, the ML3000 can receive power from either power supply 1 (A) or power supply 2 (B). The switch load is shared if both power supplies are available. The unit will not allow power to flow from a one input to another input (i.e. the two power sources are not mixed together by the switch).

When one power supply is present, the ML3000 will receive power even if the other power supply is absent, or if it is connected with reverse polarity, shorted, or grounded.

If reverse polarity connections should accidentally occur on either input, they will not damage the ML3000 or power supply (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.

The ML3000 will not receive power (and will not work) when both inputs are simultaneously absent.

The status of the power supplies can be queried with the

Power supply 1 on the switch is power input A and power supply 2 on the switch is power input B. For example,

2.4 Applications

2.4.1 Description

The Multilink ML3000 Ethernet Switch offers high performance, modularity and availability. It provides the flexibility of 100 Mbps fiber, copper, and Gigabit (1000 Mb) ports, with industry-standard LAN management software. The ML3000 switches are easily used in a variety of applications including client/server computing, secure VLAN performance upgrades to industrial networks, and streaming traffic for VOIP and audio/video applications. They can also be used in a diversified combination of mixed media in substation automation and transportation systems applications. The performance characteristics of the ML3000 switches enable them to inter-connect a series of subnets (one subnet per ML3000 switch port) in a LAN traffic center. The subnet connections may be via fiber or twisted pair cabling, Gb or 100 Mbps or 10 Mbps speed, and full-duplex or half-duplex.

The mixed-media modular capability of the ML3000 is ideal for upgrading existing Ethernet LAN networks where existing cabling must be accommodated. The fiber-built-in media capability is ideal for integrating future-proof fiber cabling into an industrial network structure.

2.4.2 ML3000 Switch for VLAN applications

The Multilin ML3000 Ethernet switch supports a VLAN application which provides security and performance in an industrial 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 ML3000 VLAN capability can be configured for use in standard Tagbased VLAN networks.

The modularity of the ML3000 switch makes it an attractive choice for use in applications with LAN connections to a large organization’s multiple site industrial facilities. The different facilities can be easily connected together with the fiber ports supported by the switch.

Future-proof fiber media can easily connect long distance subnets and provide a stable secure network to all applications using VLANs. The SNMP management capability of the ML3000 switch helps create a database of all the network subnets to easily manage the network. Secure web-based management is also included, with SSL authentication and encryption to keep out intruders.

2.4.3 ML3000 for an Industrial application

The Multilin ML3000 provides hardened enclosures, a variety of power supply options, extended temperature ratings all of which qualify this switch for any industrial power utility, surveillance and physical security, traffic control, transportation system, mining, or COTS military application. The Multilink Firmware qualifies this managed switch to operate and perform securely and reliably in mission critical applications. The industry-standard RSTP-2004 software features allow this managed switch to provide a highly available redundant network capability in any ring or mesh topology network.

The option of setting the ports at 10, 100 or 1000 Mb on copper and 100 or 1000 Mb on fiber media provide widespread options to the users to mix and match their legacy and advanced network needs. Different industrial locations can be easily connected together

FIGURE 2–10: An industrial network application with ML1600 or ML3000

Extended temperature ratings and a variety of choices for AC/DC power supplies qualify the ML3000 switch for use in non-temperature-controlled networks and many other temperature sensitive critical industrial applications where above normal temperatures occur while the network is in operation. The SNMP management capability of the ML3000 switch helps create a database of all the network subnets to easily manage the network.

2.4.4 ML3000 in a Redundant ring topology

A managed network is needed to provide a redundant ring topology for maximum reliability. In a network where any faulty cable, cable disconnection or power failure could bring down communication to the whole system, a ring topology can be configured to provide continued network operation and recovery from a fault condition. The ring topology of the network may consist of high speed LAN segments supported by 100 Mbps fiber media to provide a secure long distance LAN connection. The entire redundant network may utilize higher bandwidth Gigabit up-links to a central operations center for the vital database located in a separate secured building. The network will be manageable to provide easy, detectable, uninterrupted support through a viewable SNMP monitor.

Installation

3.1 Preparation

3.1.1 Precautions

Before installing the equipment, it is necessary to take the following precautions if the equipment is mounted in an enclosed or multiple rack assembly:

This chapter describes installation of the MultiLink ML3000 Ethernet Switch, as well as connection of the various Ethernet media types.

3.1.2 Locating the ML3000

For mounting instructions, refer to Mechanical Installation on page 3–6. The rugged metal case of the ML3000 normally protects it from accidental damage in an

industrial 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 convection while the unit is in operation. The standard ML3000 has no fans (fans are optional), so it is silent when in operation. Internal electronics use the case as a heat sink, so the unit may normally be quite warm to the touch.

1. Ensure the steady-state long-term environmental temperature around the equipment is less than or equal to 60 °C.

2. Ensure adequate airflow is maintained for proper and safe operation.

3. Ensure placement of the equipment does not overload or unevenly load the rack system.

4. Verify the equipment’s power requirements to prevent overloading of the building’s electrical circuits.

5. Verify that the equipment has a reliable and uncompromised earthing path.

6. Esnure equipment is to be installed by service personnel in a restricted operation area.

CHAPTER 3: INSTALLATION INSTALLATION

3.2 Connecting Ethernet Media

3.2.1 Description

The ML3000 switches are specifically designed to support standard Ethernet media types within a single unit. This is accomplished by using a family of modules that are individually selected and configured.

The supported media types with the corresponding IEEE 802.3, 802.3D, 802.3u, 802.3AB and 802.3z standards and connector types are as follows:

Table 3–1: Ethernet media

IEEE standard Media type Distance

100Base-FX multi-mode fiber 220 m

single-mode fiber 5 km 10Base-T twisted-pair 100 m 100Base-TX 100Base-FX 100 m

3.2.2 Connecting ST-type Fiber Optics (twist-lock)

The following procedure applies to installations using modules with ST-type fiber connectors. These are type A1, A2, A5, A6, and AF modules.

 Before connecting the fiber optic cable, remove the protective dust

caps from the tips of the connectors on the module. Save these dust caps for future use.

 Wipe clean the ends of the dual connectors with a soft cloth or lint-

free lens tissue dampened in alcohol. Ensure the connectors are clean before proceeding.

Note

One strand of the duplex fiber optic cable is coded using color bands at regular intervals. The color-coded strand must be used on the associated ports at each end of the fiber optic segment.

 Connect the transmit (TX) port on the module (light colored post) 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.

 Connect the receive (RX) port on the module (dark colored post) to

the transmit (TX) port of the remote device. Use the non-color coded fiber strand.

The LINK LED on the module will illuminate when a connection has been established at both ends (assuming power is ON). If LINK is not lit after cable connection, the cause may be improper cable polarity. Swap the fiber cables at the module connector to remedy this situation.

Note

INSTALLATION CHAPTER 3: INSTALLATION

NOTE

3.2.3 Connecting SC-type Fiber Optics (snap-in)

The following procedure applies to installations using modules with SC-type fiber connectors. These include the A3, A7, A8, G3, G4, G5, G7, G8, GC, GF, GH, and GJ modules.

When connecting fiber media to SC connectors, simply snap on the two square male connectors into the SC female jacks of the module until it clicks and secures.

3.2.4 Connecting Single-mode Fiber Optics

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 versus 50/125 or 62.5/125 microns for multi-mode, where xx/xx represent the core diameters and the core plus cladding, respectively). Single-mode fiber allows full bandwidth at longer distances and may be used to connect 10 Mb nodes up to 10 km.

The same connection procedures for multi-mode fiber apply to single-mode fiber connectors. Follow the steps listed Connecting ST-type Fiber Optics (twist-lock) on page 3–3.

3.2.5 Connecting RJ45 Twisted Pair

The RJ45 ports of the ML3000 can be connected to the following two media types: 100Base-TX and 10Base-T. CAT Five 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 m (328 ft.).

Note

Use high quality CAT. 5 cables (which work with 10 Mb and 100 Mb) whenever possible to provide flexibility in a mixed-speed network, as dual-speed ports are auto-sensing for 10 and 100 Mb/s.

The following procedure describes how to connect a 10Base-T or 100Base-TX twisted pair segment to the RJ45 port. The procedure is the same for both unshielded and shielded twisted pair cables.

The ML3000 RJ45 Gigabit ports can be connected to 1000Base-T, CAT.5E (or better), 100 Ω UTP, or shielded twisted-pair (STP) balanced cable media. The CAT.5E or 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 m (328 ft.).

 Using standard twisted pair media, insert either end of the cable with

an RJ45 plug into the RJ45 connector of the port. Even though the connector is shielded, either unshielded or shielded cables may be used.

 Connect the other end of the cable to the corresponding device.

 Use the LINK LED to ensure connectivity by noting that the LED will

be illuminated when the unit is powered and connection is established.

Note

Use high quality CAT. 5E cables (which work at both 100 and 1000 Mb) whenever possible to provide flexibility in a mixed-speed network.

CHAPTER 3: INSTALLATION INSTALLATION

The following procedure describes how to connect a 1000Base-T twisted pair segment to the RJ45 port. The procedure is the same for both unshielded and shielded twisted pair cables.

1000 Base-T connections require that all four pairs or wires be connected:

 Insert either end of the cable with an RJ45 plug into the RJ45

connector on the module. Although the connector is shielded, either unshielded or shielded cables may be used.

 Connect the other end of the cable to the corresponding device.

 Use the LINK LED to ensure connectivity by noting that the LED will

be illuminated when the unit is powered and connection is established.

3.3 Mechanical Installation

3.3.1 Rack Mounting

Installation of a MultiLink ML3000 Ethernet Switch in a 19-inch rack is a simple procedure. The units are 1 U (1.75") high. When properly installed, the front-mounted LED status indicators should be in plain view and easy to read. Rack-mount installation requires special 19-inch rack-mounted brackets and screws (included with the ML3000). These brackets attach to the front sides of the switch, which is then typically fastened on to a standard 19" RETMA rack.

The 23” brackets and the ETSI (European metric, approximately 21”) brackets are also available (optional) for rack-mounting the ML3000 switches. These brackets are popular in the telecommunications industry where they are a standard for Central Office rackmounting 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 Multilink ML3000 permits the installation of all three types (19”, ETSI, and 23”) of available brackets.

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 ML3000 switch unit. They must be ordered as separate line items.

3.3.2 Rack-mounting, Reverse mount option

The optional Reverse ML3000 model has all of the cabling (ethernet cabling, power cabling and console port cabling) connectors in the rear, and the status LEDs in the front. The status LEDs that are co-incident with the ports are still present, 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.

The case of the ML3000 has mounting holes prepared for each of the mounting arrangements. Users may choose the mounting arrangement most suitable for their installation.

9. Centralized DC power source cable securing; use at least four cable ties to secure the cable to the rack at least 4 inches apart, with the first one located within 6 inches of the terminal block.

3.4.3 Alarm Contacts

The alarm contacts feature, standard on the ML3000 ethernet switch, provides two form-C normally closed (NC) contacts to which the user can attach two sets of status monitoring wires at the alarms terminal block, see Fig 3.4.1a above or Fig 3.5a

The first NC alarm contact is a “software alarm” (labeled S/W), operated by user settings in the ML3000 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 userdefined software malfunction, such as an SNMP trap or a software security violation or an RSTP Fault, causes the contact to open and thus trigger an alarm in the user’s monitoring system.

The second NC alarm contact is held closed when there is power on the main board inside of the ML3000. This provides a “hardware alarm” (labeled H/W) 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 ML3000.

Useful information about the alarm contacts:

1. There is one four-pin terminal block (pins 1,2,3,4) provided next to the power input.

2. The left two pins (1,2) are hardware operated

3. The right two pins (3,4) are software operated

4. These are both NC (normally closed) relays

5. The switch’s 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 User Manual.

Chapter 4: Operation

Operation

4.1 Functionality

4.1.1 Switching Functionality

The MultiLink ML3000 provides switched connectivity at Ethernet wire-speed. The ML3000 supports10/100 Mbps for copper media and 10 or 100 Mb separate traffic domains for fiber ports to maximize bandwidth utilization and network performance. All ports can communicate to other ports in a ML3000, but local traffic on a port will not consume any of the bandwidth on any other port.

The ML3000 is a plug-and-play device. There is no software configuration necessary for basic operation, installation, or maintenance. Optional half/full-duplex mode and 10 or 100 Mbps selection for the switched ports must be configured through software as per the requirement. The internal functions of both are described below.

4.1.2 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 un-interrupted operation of the network (such as occasional multi-cast packets) are forwarded to all ports.

The ML3000 operates in the store-and-forward switching mode, which eliminates bad packets and enables peak performance when there is heavy traffic on the network.

4.1.3 Address Learning

All ML3000 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 ML3000 automatically keeps up with node locations.

MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL 4–1

OPERATION CHAPTER 4: OPERATION

An address-aging algorithm causes least-used addresses to fall out in favor of frequentlyused addresses. To reset the address buffer, cycle power down-and-up.

4.1.4 Status LEDs

The following status LEDs are included:

• PWR: Power LED, ON when external power is applied to the unit.

• LK: Steady ON, link status for 10 Mbps and 100 Mbps operation.

• ACT: ON with port activity for 10 Mbps and 100 Mbps 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 100 Mbps, OFF when the speed is

10 Mbps.

4.1.5 Up-link Manual Switches (for RJ45 port only)

The module has a manual up-link switch, located on the inside of the board next to the 10/ 100Mb (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 Up-link Switch position is configured as (=) straight position by default from the factory settings on all the RJ45 ports, either used for all copper module or combo module.

4.1.6 Auto-Cross(MDIX) and Auto-negotiation, for RJ-45 ports

The RJ-45 ports independently support auto-cross (MDI or MDIX) in auto-negotiation mode and will work properly with all the other connected devices with RJ-45 ports whether they support Auto-negotiation (e.g 10Mb Hub, media converter) or fixed mode at 10Mb or 100Mb Half/Full Duplex(managed switch) or not. No cross-over cable is required while using the ML3000’s copper port to other devices. Operation is according to the IEEE 802.3u standard.

The Managed ML3000’s Fast Ethernet copper ports can be set for either fixed 100Mb speed or for 10/100 F/H N-way auto-negotiation per the IEEE802.3u standard. The selection is made via MNS software. The factory default setting is for auto-negotiation. At 10Mb or 100Mb-fixed speed, the user may select half- or full-duplex mode by MNS Software for each RJ-45 port separately. For detail information See Section 2.3 of this manual for information to access the “6K-MNS Software user guide”

One frequently-used application for the Managed Multilink ML3000 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 the 100Mb fixed speed. Attachments to a 10/100 auto-negotiation port typically will not work properly. The ML3000 Switch’s RJ-45 ports handle this situation by configuring the ports as per desired through MNS software port settings and can check the port status of each port after the change.

When Multilink ML3000 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.

4–2 MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL

CHAPTER 4: OPERATION OPERATION

NOTE

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 ML3000’s RJ-45 ports will try to detect its idle signal to determine 10 or 100 speed, and will default to half-duplex at that speed per the IEEE standard.

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 10Mb or

100Mb speed and/or in full- or half-duplex mode, and can send/receive autonegotiation 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. These are exceptions to the “negotiate at LINK – enabled” rule above, but may be occasionally encountered.

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 Multilink ML3000 Fast Ethernet switched ports operating at 100Mb half-duplex, the bit time delay is 50BT.

4.1.7 Flow Control (IEEE 802.3x)

The ML3000 incorporates a flow-control mechanism for full-duplex mode. Flow-control reduces 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 100 Mb port to a 10 Mb port and the 10 Mb port is unable to keep up. It can also occur when multiple 100 Mb ports are attempting to transmit to one 100 Mb port, and in other protracted heavy traffic situations.

The ML3000 implements 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 ML3000 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

In half-duplex mode, the ML3000 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.

The use of either multi-mode or single-mode fiber to operate at 100 Mbps speed over long distances (i.e., in excess of 400 m) can be achieved only if the following are applied:

1. The 100 Mb fiber segment must operate in full-duplex (FDX) mode (i.e. the fullduplex (factory default).

2. The worst-case OPB of the fiber link must be greater than the fiber cable's passive attenuation, where attenuation is the sum of cable loss, LED aging loss, insertion loss, and safety factor.

IP Addressing

5.1 IP Address and System Information

5.1.1 Overview

It is assumed that the user has familiarity with IP addresses, classes of IP addresses and related netmask schemas (for example, class A, B, and C addressing).

Without an IP address, the switch operates as a standalone Layer 2 switch. Without an IP address, you cannot:

• Use the web interface to manage the switch

• Use telnet to access the CLI

• Use any SNMP Network Management software to manage the switch

• Use NTP protocol or an NTP server to synchronize the time on the switch

• Use TFTP or FTP to download the configurations or upload software updates

• Run ping tests to test connectivity

To set the IP address, please refer to Setting the IP Parameters on page 1–13. Once the IP address is set, the CLI can be accessed via telnet as well as the console interface. From now on, all commands discussed are accessible from the command line interface, irrespective of access methods (i.e. serial port or in band using telnet).

To verify the IP address settings using the command line interface, the command can be used as follows:

ML3000> show ipconfig

CHAPTER 5: IP ADDRESSING IP ADDRESSING

5.2 Importance of an IP Address

5.2.1 DHCP and bootp

DHCP is commonly used for setting up addresses for computers, users and other user devices on the network. bootp is the older cousin of DHCP and is used for setting up IP addresses of networking devices such as switches, routers, VoIP phones and more. Both of them can work independent of each other. Both of them are widely used in the industry. It's best to check with your network administrator as to what protocol to use and what the related parameters are. DHCP and bootp require respective services on the network. DHCP and bootp can automatically assign an IP address. It is assumed that the reader knows how to setup the necessary bootp parameters (usually specified on Linux/UNIX systems in

/etc/boopttab directory).

the

5.2.2 bootp Database

Bootp keeps a record of systems supported in a database - a simple text file. On most systems, the entry by which the and subnet mask of the switch would be as follows:

Likewise, the bootcfg argument is valid only with the bootp type. This option allows the switch to load the configuration file from the bootp server. This is useful when a new switch is put on a network and the specific configurations are loaded from a centralized bootp server

The following example changes the boot mode of the switch:

The telnet client is enabled on the ML3000. The ML3000 supports five simultaneous sessions on a switch: four telnet sessions and one console session. This allows many users to view, discuss, or edit changes to the ML3000. This is also useful when two remote users want to view the switch settings. The telnet client can be disabled through the command line interface by using the

telnet disable command with the following syntax:

telnet <enable|disable>

Telnet can also be disabled for specific users with the

useraccess command. Refer to

Setting the IP Parameters on page 1–13 for details. Multiple telnet sessions started from the CLI interface or the command line are serviced by

the ML3000 in a round-robin fashion (that is, one session after another). If one telnet session started from an ML3000 is downloading a file, the other windows will not be serviced until the file transfer is completed.

The following example changes the telnet access. In this case, the enable command was repeated without any effect to the switch.

NOTE

The ML3000 will time out an idle telnet session. It may be useful to see who is currently connected to the switch. It may also be useful for a person to remotely terminate a telnet session. To facilitate this, the ML3000 supports the following two commands:

show session kill session id=<session>

For example:

ML3000# user ML3000(user)## useraccess user=peter service=telnet enable Telnet Access Enabled. ML3000(user)## exit ML3000# show session Current Sessions: SL# Sessn Id Connection User Name User Mode

kill session command.

Note

A maximum of four simultaneous telnet sessions are allowed at any time on the switch. The commands in these telnet windows are executed in a round robin fashion; that is, if one window takes a long time to finish a command, the other windows may encounter a delay before the command is completed. For example, if one window is executing a file download, the other windows will not be able to execute the command before the file transfer is completed. As well, if a outbound telnet session is started from the switch (through a telnet window) then other windows will not be able to execute a command until the telnet session is completed.

System variables can be changed. Below is a list of system variables which GE recommends changing.

•

System Name: Using a unique name helps you to identify individual devices in a

network.

System Contact and System Information: This is helpful for identifying the

• administrator responsible for the switch and for identifying the locations of individual switches.

To set these variables, change the mode to be SNMP configuration mode from the manager mode using the following syntax

snmp setvar [sysname|syscontact|syslocation] =<string>

The following command sequence sets the system name, system location and system contact information.

ML3000# snmp ML3000(snmp)## setvar ?

setvar: Configures system name, contact or

5.3.4 Network Time

Many networks synchronize the time using a network time server. The network time server provides time to the different machines using the Simple Network Time Protocol (SNTP). To specify the SNTP server, one has to

1. Set the IP parameters on the switch

2. Define the SNTP parameters

5–10 MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL

CHAPTER 5: IP ADDRESSING IP ADDRESSING

To set the SNTP parameter with the command line software, enter the SNTP configuration mode from the manager. The

setsntp, sync, and sntp commands can then be used to

setup the time synchronization automatically from the SNTP server. Note it is not sufficient to setup the SNTP variables. Make sure to setup the synchronization frequency as well as enable SNTP. The syntax for the above commands is shown below.

setsntp server = <ipaddress> timeout = <1-10>

retry = <1-3> sync [hour=<0-24>] [min=<0-59>] (default = 24

hours) sntp [enable|disable]

To set the SNTP server to be 3.94.210.5 (with a time out of 3 seconds and a number of retries set to 3 times); allowing the synchronization to be ever 5 hours, the following sequence of commands are used

ML3000# sntp ML3000(sntp)## setsntp server=3.94.210.5 timeout=3 retry=3

SNTP server is added to SNTP server

database ML3000(sntp)## sync hour=5 ML3000(sntp)## sntp enable

SNTP is already enabled. ML3000(sntp)## exit ML3000(sntp)#

SNTP parameters can be configured through the EnerVista Secure Web Management software with the Configuration > SNTP menu item. The SNTP menu allows the time zone (hours from GMT) to be defined along with other appropriate parameters on setting the time and synchronizing clocks on network devices.

MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL 5–11

IP ADDRESSING CHAPTER 5: IP ADDRESSING

NOTE

The edit button allows editing of the SNTP parameters as shown below. Adding or deleting SNTP servers is accomplished by using the add and delete buttons. Clicking the edit button allows the specific SNTP parameter settings to be modified.

After the proper SNTP values are entered, click OK to register the changes, or click Cancel to back out from the changes made.

To add an SNTP server, click the add button on the Configuration > SNTP menu. The menu prompts you to add IP address of an SNTP server, the time out in seconds and the number of retries, before the time synchronization effort is aborted. The Sync Now button allows synchronization as soon as the server information is added.

Note

If your site has internet access, there are several SNTP servers available online. A quick search will yield information about these servers. You can use the IP address of these servers; however, please ensure the server can be reached by using the

ping command can also be launched from the EnerVista software.

The

ping command.

CHAPTER 5: IP ADDRESSING IP ADDRESSING

The Time Out value is in seconds. Note the time server can be a NTP server available on the Internet. Ensure the IP parameters are configured for the switch and the device can be pinged by the switch. Once the server is added, it is listed with the other SNTP servers.

5.4 System Configuration

5.4.1 Saving and Loading – Command Line

Note

Place the Switch offline while transferring Setting Files to the Switch. When transferring Settings Files from one Switch to another, the IP address of the originating Switch will also be transferred. The user must therefore reset the IP address on the receiving Switch before connecting to the network.

Configuration changes are automatically registered but not saved; that is, the effect of the change is immediate. However, if power fails, the changes are not restored unless they saved using the

save command. It is also a good practice to save the configuration on

another network server using the tftp or ftp protocols. Once the configuration is saved, it can be loaded to restore the settings. At this time, the saved configuration parameters are not in a human readable format. The commands for saving and loading configurations on the network are:

saveconf mode=<serial|tftp|ftp> <ipaddress> file=<name>

loadconf mode=<serial|tftp|ftp> <ipaddress> file=<name>

Ensure the machine specified by the IP address has the necessary services running. For serial connections, x-modem or other alternative methods can be used. In most situations, the filename must be a unique, since overwriting files is not permitted by most ftp and tftp servers (or services). Only alphanumeric characters are allowed in the filename.

The following example illustrated how to save the configuration on a tftp server

ML3000# saveconf mode=tftp 3.94.240.9 file=ML3000set Do you wish to upload the configuration?

['Y' or 'N'] Y

The saveconf and loadconf commands are often used to update software. Before the software is updated, it is advised to save the configurations. The re-loading of the configuration is not usually necessary; however, in certain situations it maybe needed and it is advised to save configurations before a software update. The

loadconf command

requires a reboot for the new configuration to be active. Without a reboot the older configuration is used by the MultiLink family of switches.

saveconf and loadconf commands are often used to update software to the

The ML3000. These commands will be deprecated in the version 2.x and above, and replaced with the instead of

ftp, tftp, or xmodem commands. It is advised to begin using these commands

saveconf and loadconf.

5.4.2 Config file

Multilink ML3000 Firmware can use the ftp or tftp (or xmodem if using the CLI) to upload and download information to a server running the proper services. One useful capability provided is export of the CLI commands used to configure the switch. To do this, use Config Upload/Download.

Using Config Download, examination of the contents of the saved file would appear as shown below:

Using SWM, the need to display specific CLI commands for configuring capabilities is not needed. The menus are modular and are alphabetically sorted to display each necessary component in a logical manner. This section is repeated from the CLI manual, should the need arise to view the necessary commands. The best way to view these commands is to telnet to the switch using the Telnet menu from the Administration menu.

To display the configuration or to view specific modules configured, the ‘show config’ command is used as described below.

Additional capabilities have been added to save and load configurations. The commands are:

The arguments are describe below:

type: Specifies whether a log file or host file is uploaded or downloaded. This can also

perform the task of exporting a configuration file or uploading a new image to the switch

host, ip, file, user, pass: These parameters are associated with ftp/tftp server

communications.

The user can save the configuration in old (v2 format) and new (v3 format). The v3 format must be used to utilize the ASCII and CLI Script capability.

save [format=v2|v3]

Note

With release 1.7 and higher, the configuration can be saved in the older format (binary object) or in a new format as an ASCII file. The new format is recommended by GE Multilin. Use the old format only if there are multiple MultiLink switches on the network running different versions of software. GE Multilin recommends upgrading all switches to the most current software release.

To ease the process of uploading and executing a series of commands, the ML3000 can create a host (equivalent to creating a host table on many systems). The command for creating a host is:

host <add|edit|del> name=<host-name> ip=<ipaddress> user=<user> pass=<password>

show host command displays the host table entries

5.4.5 Script File

Script file is a file containing a set of CLI commands which are used to configure the switch. CLI commands are repeated in the file for clarity, providing guidance to the user editing the file as to what commands can be used for modifying variables used by Firmware. The script file does not have a check sum at the end and is used for configuring a large number of switches easily. As with any configuration file that is uploaded, GE Multilin, Inc. recommends that modifications of this file and the commands should be verified by the user in a test environment prior to use in a "live" production network.

The script file will look familiar to people familiar with the CLI commands as all the commands saved in the script file are described in the CLI User Guide. A sample of the script file is shown below.

GE Multilin, Inc. recommends that modifications of this file and the commands should be verified by the User in a test environment prior to use in a "live" production network

To ease the process of uploading the script files, use the Script Upload/Download capability described above.

5.4.6 Saving and Loading – EnerVista Software

Note

After configuration changes are made, all the changes are automatically saved. It is a good practice to save the configuration on another server on the network using the

ftp protocols. Once the configuration is saved, the saved configuration can be reloaded

tftp

to restore the settings. At this time, the saved or loaded configuration parameters are not in a human readable format.

The following figure illustrates the FTP window, which can be used to save the configuration, as well as up load new images or reload a saved configuration.

Ensure the machine specified by the IP address has the necessary services running on it. For serial connections, x-modem or other alternative methods can be used. Generally, the filename name must be a unique filename, as over-writing files is not permitted by most FTP and TFTP servers (or services).

The following figure illustrates saving the configuration on a TFTP server. Note that the menu is similar to the FTP screen described earlier.

MULTILINK ML3000 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL 5–23

IP ADDRESSING CHAPTER 5: IP ADDRESSING

This process can also be used to update new software to the managed MultiLink switches. Before the software is updated, it is advised to save the configurations. Reloading of the configuration is not usually necessary, but in certain situations it may be needed, and it is recommended that you save configurations before a software update. Make sure to reboot the switch after a new configuration is loaded.

The file transfer operations allowed are:

1. Image Download (or Image Upload): Copy the ML3000 image from switch to the server (or from the server to the switch). The “Image Upload” option is commonly used to upgrade the ML3000 image on the switch.

2. Config Download (or Config Upload): Save the configuration of the switch on the server (or load the saved configuration from the server to the switch). This option is used to save a backup of the ML3000 configuration or restore the configuration (in case of a disaster.)

3. Script Download (or Script Upload): Save the necessary CLI commands used for configuration of the switch (or upload the necessary CLI commands needed to configure the switch). This option is used to ease the repetitive task of configuring multiple commands or reviewing all the commands needed to configure the ML3000.

4. Host Download (or Host Upload): Save the host information. The hosts are created by the Configuration - Access - Host commands

5. Log Upload - Save the log file on the ftp/tftp server

To save any changes,

 Click on the save ( ) icon.

The software will ask again if the changes need to be saved or ignored.

 If the changes need to be ignored, click on Cancel and reboot the
