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.
1.3.2EnerVista 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
1.3.3Before 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.
COMMAND LINE INTERFACE FIRMWARECHAPTER 1: SPECIFICATIONS
1.4Command Line Interface Firmware
1.4.1Console Connection
The connection to the console is accessed through the DB-9 RS232 connector 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 VT100 compatible terminal or a
PC running terminal emulation firmware to the console port.
USB-to-serial adapters are also available for computers that do not native serial ports but
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.
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.
1.4.2Console Setup
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 emulating a VT100 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
1.4.3Console Screen
Once the console cable is connected to the PC and the firmware configured, ML810 legal
disclaimers and other text scrolls by on the screen.
CHAPTER 1: SPECIFICATIONSCOMMAND LINE INTERFACE FIRMWARE
The line interface prompt appears displaying the switch model number (e.g. ML810>)
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.
• ML810>
Operator Level - for running operations queries
• ML810#
Manager Level - for setting and reviewing commands
• ML810##
Configuration Level - for changing the switch parameter values
For additional information on default users, user levels and more, refer to User Management on page 1–12.
1.4.4Logging 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.
1.4.5Automatic IP Address Configuration
The ML810 is operational immediately after it is powered up. The advanced management
and configuration capabilities of the ML810 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://
Ensure both firmware components are installed before proceeding.
The ML810 can search the network for commonly used services that can issue an IP
address. If the switch is connected to a network, the ML810 uses the following process to
find an IP address.
If the ML810 is not connected to a network, then proceed to Step 3 below. or use the
default IP address.
Step 1:
The ML810 will scan the network for a DHCP server. If the server responds, the ML810 will
acquire and set the assigned IP address. To manage the switch, determine the assigned IP
address and enter as follows in Internet Explorer:
COMMAND LINE INTERFACE FIRMWARECHAPTER 1: SPECIFICATIONS
https://<assigned_IP_address>
Ensure that https is entered, not http, and that there is connectivity (that is, you can ping
the switch).
Step 2:
If there is no response from a DCHP server, the ML810 will query for a BOOTP server. If the
server responds, the ML810 will acquire and set the assigned IP address. To manage the
switch, determine the assigned IP address and enter as follows in Internet Explorer:
https://
<assigned_IP_address>
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 ML810 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 ML810 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
1.4.6Setting 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.
This manual assumes the reader is familiar with IP addressing schemes as well as how net
mask is used and how default gateways and routers are used in a network.
Reboot gives an opportunity to save the configuration prior to shutdown. For a reboot,
simply type in the command
reboot. Note that even though the passwords are not
changed, they can be changed later.
ML810# reboot
Proceed on rebooting the switch? ['Y' or 'N'] Y
Do you wish to save current configuration? ['Y' or 'N'] Y
ML810#
The ML810 forces an answer by prompting with a “Y” or a “N” to prevent accidental
keystroke errors and loss of work.
The parameters can be viewed at any time by using the
show command. The show
command will be covered in more detail later in various sections throughout the
document.
The example below illustrates the basic setup parameters. You can use

Some of the parameters in the MultiLink family of switches are shown above. The list of
parameters below indicates some of the key parameters on the switch and the
recommendations for changing them (or optionally keeping them the same).
1.4.7Privilege Levels
Two privilege levels are available - manager and operator. Operator is at privilege level 1
and the manager is at privilege level 2 (the privilege increases with the levels). For example,
to set up a user for basic monitoring capabilities use lower number or operator level
privilege (level 1).
The Manager level provides all operator level privileges plus the ability to perform systemlevel actions and configuration commands. To select this level, enter the
command at the Operator level prompt and enter the Manager password, when
name>
prompted.
enable <user-name>
For example, switching from an operator-level to manager-level, using the enable
command is shown below.
ML810> enable manager
Password: *******
ML810#
Note the prompt changes with the new privilege level.
Operator privileges allow views of the current configurations but do not allow changes to
the configuration. A “>” character delimits the operator-level prompt.
Manager privileges allow configuration changes. The changes can be done at the
manager prompt or for global configuration as well as specific configuration. A “#”
character delimits any manager prompt.
enable <user-
1.4.8User Management
A maximum of five users can be added per switch. Users can be added, deleted or
changed from a manager level account. There can be more than one manager account,
subject to the maximum number of users on the switch being restricted to five.
To add a user, use the
name. The password is recommended to be at least 8 characters long with a mix of upper
case, lower case, numbers and special characters.
add user=<name> level=<number>
The following example adds a user “peter” with manager-level privilege:
ML810# user
ML810(user)## add user=peter level=2
Enter User Password:******
Confirm New Password:******
ML810(user)##
To delete a user, use the delete command as shown below.

Multilink ML810 Managed Edge Switches provide configurability in an entry-level
industrial-grade package. The high performance ML810 base unit comes with four 10/100
copper ports (which may be either regular or PoE). Up to 4 100Mb fiber ports or up to four
more 10/100 copper ports or combinations, may also be configured. In addition, one or
two Gb ports may be configured as 10/100/1000 copper or SFP fiber in any ML810 base
unit.
Multilink ML810 comes with the best-of-breed MultiLink ML810 Managed Edge Switch
firmware.
Multilink ML810s are ideal for building a switched, hardened Ethernet network
infrastructure, connecting edge devices such as PLCs and IEDs with upstream switches or
routers. Designed for use in industrial applications such as factory floors and control
cabinets, industrial video surveillance systems with PoE, power utility substations, tariffed
carrier field facilities, or transportation and oil and gas, the rugged Multilink ML810 handles
stressful workloads (mixes of bursty data traffic and priority streaming traffic) as well as
harsh environmental conditions.
The ML810 metal case serves as a heat sink and a sealed-case design enables the unit to
operate in harsh Industrial grade environments and achieves high EMI noise immunity.
Heavy duty Ethernet Switch jobs are readily accommodated with an extended
temperature rating of -40˚C to 60˚C by the UL Component Parts method, or -40˚C to 85˚C
by the IEC 60068 Type-Test method. With options such as several popular DC power input
types, AC power and DIN-Rail mounting, the hardened Multilink ML810 is a “multi-purpose”
Industrial Ethernet Switch.
The ML810 managed switches also provides a PoE option via power –inside PoE base unit
(ML810P-48VDC) on Slot A and allows the users to utilize up to 4-ports of PoE to support
802.3af Powered devices. See details for PoE base unit in sec 5.1.11. The Power Sourcing
Equipment (PSE) is fully compatible with Powered Devices (PD)(e.g wireless access points, IP
phones) that comply with the IEEE 802.3af PoE standard. The PoE switch ports have an
auto-sensing algorithm, so that they provide power only to 802.3af, PoE end devices. PoE
is managed by a multi-stage handshake to protect equipment from damage and to
manage power budgets .The PoE ports will discontinue supplying power when the PoE
powered devices are disconnected. This feature supports the 802.3af PoE PSE standard for
over-current protection, under-current detection, and fault protection.
High performance features include non-blocking unicast traffic speed on all ports and
802.1p QoS Traffic Prioritization. Multilink ML810 switches are “plug-and-play” and are
designed for use in connecting edge devices such as PLCs, IEDs and PoE video cameras
with upstream switches and routers where a mix of bursty data traffic and priority
streaming traffic for video surveillance and cell-tower applications are present.
Multilink ML810 Managed Edge Switches have heavy-duty steel cases and are readily
available with standard Industrial grade 24VDC power. Alternative internal DC power
options are available. Internal AC power and DC power input types may be 12V, 24V, 48V,
125V, 250V and dual source DC input is optional on the ML810.
Alarm Relay contacts provided on each Multilink ML810 Switch monitor the hardware and
software through traps, providing a record of any losses of power signals and other userdefined software events. See Section 3.5 for details.
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 Multilink ML810 can do
its part to prevent any QOS degradation while it is handling Ethernet traffic through its
ports and buffers.
The Multilink ML810 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 (R2) supports two priority queues that can be shared across the eight levels of
defined packet priorities for application-specific priority control by the user through
software configuration settings.
2.2.2Frame Buffering and Flow Control
Multilink ML810’s are store-and-forward switches. Each frame (or packet) is loaded into
the Switch’s memory and inspected before forwarding can occur. This technique ensures
that all forwarded frames are of a valid length and have the correct CRC, i.e., are good
packets. This eliminates the propagation of bad packets, enabling all of the available
bandwidth to be used for valid information.
While other switching technologies (such as "cut-through" or "express") impose minimal
frame latency, they will also permit bad frames to propagate out to the Ethernet segments
connected. The "cut-through" technique permits collision fragment frames (which are a
result of late collisions) to be forwarded which add to the network traffic. Since there is no
way to filter frames with a bad CRC (the entire frame must be present in order for CRC to
be calculated), the result of indiscriminate cut-through forwarding is greater traffic
congestion, especially at peak activity. Since collisions and bad packets are more likely
when traffic is heavy, the result of store-and-forward operation is that more bandwidth is
available for good packets when the traffic load is greatest .
When the Multilink ML810 Switch detects that its free buffer queue space is low, the Switch
sends industry standard (full-duplex only) PAUSE packets out to the devices sending it
packets to cause “flow control”. This tells the sending devices to temporarily stop sending
traffic, which allows the traffic to catch-up 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 Multilink ML810 Switches is a collision-based flowcontrol 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.
•Managed switching for high performance Ethernet LANs
Multilink ML810 Switches provide unicast non-blocking (all ports can run at full speed
at once) performance with standard Managed Network Software. They are typically
used in LAN traffic centers with up to 8 100Mb +2 Gigabit ports for backbone
connections, where managed network services are desired.
•Switching services includes 802.1p QoS packet prioritization
The Multilink ML810 switching hardware supports QoS, giving packet processing
priority to priority tagged packets according to the IEEE 802.1p standard. For portand application-specific priorities of data, the QoS software may be configured.
•Fiber Ports Built-In
Multilink ML810 Managed Edge Switches are designed to naturally include fiber ports,
and support mixes of multi-mode, single-mode, 100Mb and 1000Mb speed; full-and
half-duplex; classic Small Form Factor (SFF) and Small Form Pluggable (SFP) fiber
connectors. RJ-45 10/100 ports can also be configured in the mix of port types.
•Relay Contacts for monitoring internal power and user-defined software events
Two Alarm Relay contacts monitor basic operations. One is for hardware, and will
signal loss of power internally. The other is software controlled and will signal userdefined software events such as a security violation or an S-Ring fault condition.
•Vertical mounting for efficient convection cooling, no fans, extended temperature
Mounting brackets for vertical mounting are included. DIN-Rail mounting hardware is
optional.
•All types of power input, 12, 24, 48, 125, 250VDC and AC
The ML810 can be configured with the user’s choice of DC power supplies: 12V and
24V for factory floor, 48V for tariffed carrier field facilities and for PoE-powered
applications such as IP video surveillance, and 125V or 250V for substations. An
internal AC power supply may also be chosen, universal AC for use worldwide.
•Heavy-duty design for Industrial Ethernet and extended temperature operation
Fiber ports take more power than copper ports, but the Multilink ML810 design
provides for this with heavy-duty components. The ambient temperature dual-rating
is 60`C per UL methods, and 85°C per IEC type test methods.
•MultiLink ML810 Managed Edge Switch firmware.
Managed Networks Software (MNS) basic version, combined with a Magnum 6K-Series
Switch, provides power and efficiency in a managed Ethernet platform. A full range of
industry-standard software functions in the MultiLink ML810 Managed Edge Switch
firmware product enables the versatile Magnum 6K Switches to perform efficiently in
a wide range of managed LAN applications, including redundant topologies.
•S-Ring and Link Loss Learn for economical high availability using ring topology
S-Ring combined with the Link-Loss-Learn feature provides reliable fast recovery of a
fault in an economical ring topology combining unmanaged and managed switches.
•RSTP-2004 for rings and meshes, fastest fault recovery, interoperability
RSTP-2004 provides reliable fast recovery from a fault in a redundant LAN, which may
include Multilink switches and routers as well as other vendors industry-standardRSTP products. Redundant topologies may include rings, dual-rings, and complex
meshes.
Multilink ML810 Edge Switches offer high performance, modularity and availability. They
provide the flexibility of 100Mbps fiber and copper ports as well as single or dual Gigabit
(1000Mb) ports, with industry-standard LAN management software. Multilink ML810
Switches are easily used in a variety of applications including client/server computing,
secure VLAN- performance upgrades to departmental networks, and stream traffic for
VOIP and audio/video applications. They can also be used in a much diversified
combination of mixed media in Industrial floor applications. The performance
characteristics of the ML810 Switches enable them to inter-connect a series of subnets
(one subnet per ML810 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.
The mixed-media modular capability is ideal for industrial applications where existing
Ethernet LAN network cabling must be accommodated. The fiber-built-in media capability
is ideal for integrating future-proof fiber cabling into the LAN structure.
Figure 2-1: Multilink ML810 or ML1600 Switch for an Industrial Application
Equipped with lots of useful features including hardened enclosures, a wide spread of DC
power supply options, and extended temperature ratings qualifies the Multilink ML810
Managed switch for any Industrial factory-floor, traffic control, transportation system, or
power utility application. The several MultiLink ML810 Managed Edge Switch firmware
operated features qualifies this managed switch to operate and perform securely and
reliably in all critical applications. The addition of S-Ring and the Link-Loss-Learn software
features allow this Managed switch to provide a very secure highly available redundant
network capability in any ring topology network.
The Managed ML810’s modularity along with the MultiLink ML810 Managed Edge Switch
firmware features remarkably handle industrial environments (i.e. where the factory floors
are networked with Ethernet based mixed-media LANs equipped with PLCs, computers for
taking readings and data from Machines, Client/ Server databases, etc. and sending these
important data to the central office data warehouses) very securely and reliably. The DINRail Mounting options on the Multilink ML810 allow the factory floor’s industrial user to
mount the ML810 securely anywhere on their Network setup.
The option of setting the ports at 10 or 100Mb on copper and 100Mb on fiber media
provide widespread options to the users to mix and match their legacy and advance
network needs. The modularity of the ML810 Managed Edge Switches make them an
attractive choice for use in applications with LAN connections to an organization’s multiple
site offices and factory- floors. The different locations can be easily connected together
with the Fiber ports supported by the Multilink ML810 Switch. A main NT-server in a secure
area protected from earthquake or fire hazards can be connected to the full duplex Gigabit
Fiber port.
Extended temperature ratings and a variety of options for AC/DC power supplies qualify
this managed ML810 switch for use in non-temperature controlled networks and many
other temperature sensitive critical Industrial applications where above normal room
temperatures occur while the network is in operation. 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 Multilink ML810 Switch helps create
a database of all the network subnets to easily manage the network.
Example 2: A managed network is needed to provide a redundant ring topology for
maximum redundancy. In a network where any faulty cable, cable disconnection or power
failure can bring the whole thing down, a ring switch can be reconfigured and up and
running in milliseconds. The ring topology of the network consists of high speed LAN
segments supported by 100Mbps full-duplex future-proof fiber media to provide a secure
long distance LAN connection. The entire network is sharing a higher bandwidth Gigabitenabled data-mining server for the vital database located in a separate secured building.
The copper ports are required for multiple subnets inside the power plant to check the
status of other Ethernet units. The entire spread network will be manageable to provide
easy, detectable, uninterrupted support through a viewable SNMP monitor.
Figure 2-2: Multilink ML810 or ML1600 equipped with S-Ring in redundant ring solution
The Multilink ML810 Managed Edge Switch equipped with a mix of copper and fiber ports
provides an economical and seamless solution to many requirements. The userconfigurable Multilink ML810 provides an extra boost to the network requirements by
providing copper/fiber media along with the higher bandwidth support of 10/100 and
1000Mb. The user can utilize the SNMP feature equipped with VLAN, RMON, STP and other
standard managed LAN features to provide a secure and stable network.
The ML810 Managed Fiber with S-ring and Link-Loss-Learn features easily fulfill the
redundant requirement with a secure and fast reconfiguration time for cable breakup
when set up in a ring topology. The Gigabit port option boosts the bandwidth for high
speed to support the peak traffic and minimize congestion.
Example 3: In another application in an industrial environment , a 12 port Nebs compliant,
24VDC managed switch is required to meet the fiber and copper connections to cover the
wider area of video CCTV. The switch must be SNMP enabled and managed to easily
monitor the whole setup.
The Multilink ML810 managed edge switch easily qualifies for this requirement with the
various features and modularity it has. Loaded with MultiLink ML810 Managed Edge Switch
firmware, the edge switch provides a very effective and economical solution for the video vignette environment.
The security features (e.g. port-security, VLANs, SNMPv3, secure telnet, etc.) also boost the
Multilink managed switches to provide a very effective and reliable solution. The
modularity feature to support both copper and fiber at either 10/100/1000Mb speeds
easily meets the various speeds of legacy and future broadband requirements.
In a fast growing secure video environment, the ML810 is a reliable and secure solution.
The modular design of the Multilink ML810, provides a wide range of copper/fiber options
to meet requirements. The Gigabit uplink for storage or broadband uplink allows the
telecom user a very effective solution to store their sensitive data securelyFig 2.5c Multilink
ML810 deployed in a video security CCTV application for monitoring and securing the
premises.
Before installing the equipment, it is necessary to take the following precautions:
This section describes installation of the Multilink ML810 Switches, as well as connection of
the various Ethernet media types.
• If the equipment is mounted in an enclosed or multiple rack assembly, the steadystate long-term environmental temperature around the equipment must be less
than or equal to 60
• If the equipment is mounted in an enclosed or multiple rack assembly, adequate
airflow must be maintained for proper and safe operation.
• If the equipment is mounted in an enclosed or multiple rack system, placement of
the equipment must not overload or load unevenly the rack system.
• 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.
• If the equipment is mounted in an enclosed or multiple rack assembly verify that
the equipment has a reliable and uncompromised earthing path.
•For vertical panel mounting and wall mounting, see Section 3.3.1
•For DC power input data, see Appendix B. For Dual Source, see Appendix C.
The rugged metal case of the Multilink ML810 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 convection while the unit is in operation. The ML810 has no fans, 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.
The Multilink ML810 Switches are specifically designed to support standard Ethernet
media types within a single Switch unit. This is accomplished by using four popular Fiber
Connectors which can be individually selected and configured.
(See Section 5.1 for a description of the Modules)
The various media types supported along with the corresponding IEEE 802.3, 802.3D,
802.3u, 802.3AB and 802.3z standards and connector types are as follows:
See the ML810 Product Page on http://www.gedigitalenergy.com/
calculations, to find fiber cable distance information.
3.2.1Connecting Twisted Pair (CAT3, CAT5, UTP or STP)
The RJ-45 ports of the Multilink ML810 can be connected to the following two media types:
100BASE-TX and 10BASE-T. CAT 5 cables should be used when making 100BASE-TX
connections. When the ports are used as 10BASE-T ports, CAT 3 may be used. In either
case, the maximum distance for unshielded twisted pair cabling is 100 meters (328 ft).
Note
It is recommended that high quality CAT. 5 cable be used whenever possible in order to
provide flexibility in a mixed-speed network, since 10/100 copper switched ports are autosensing for either 10 and 100Mb/s.
The following procedure describes how to connect a 10BASE-T or 100BASE-TX twisted pair
segment to the RJ-45 port. The procedure is the same for both unshielded and shielded
twisted pair cables.
1.Using standard twisted pair media, insert either end of the cable with an RJ-45 plug
into the RJ-45 connector of the port . Note that, even though the connector is shielded,
either unshielded or shielded cables and wiring may be used.
for Power budget
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.
For Power Substations: In support of the IEEE 1613 Class 2 standard, GCI advises that, for
substation applications, the RJ-45 ports are intended for connectivity to other
communication equipment such as routers or telecommunication multiplexers installed in
close proximity (i.e., less than 2 meters or 6.5ft) to the ML810. It is not recommended to use
these ports in substation applications to interface to field devices across distances which
could produce high (greater than 2500V ) levels of ground potential rise (GPR) during lineto-ground fault conditions. The ML810 passes the 1613specifications for zero packet loss
with fiber ports & with RJ-45 ports used as indicated here.
3.2.2Connecting Twisted Pair (CAT5e or better, UTP or STP)
The RJ-45 Gigabit ports of the Multilink ML810 can be connected to the media types,
1000BASE-T or CAT 5E or better 100-ohm UTP or shielded twisted pair (STP) balanced cable.
The CAT 5E or better 100-ohm UTP or shielded twisted pair (STP) balanced cable is
recommended to use when making 1000BASE-TX connections. In either case, the max
distance for unshielded twisted pair cabling is 100 meters (328 ft).
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.
3.2.3Connecting 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, about 70km with the single-mode LC.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
communications for both telecommunication and data communications applications. Due
to its compact, hot pluggable characteristics, SFPs are becoming a very popular choice for
various applications. The small-chassis Multilink ML810 is designed for industry-standard
Gb-SFPs for user selection of the SFP gigabit media type as desired.
All SFPs used in Multilink ML810s are compliant with the industry standard Multi-Source
Agreement (MSA) ensuring compatibility with a wide range of networking kit. (See Section
1.2 for the SFP’s available for the ML810.)
It is highly recommended to remove the fiber cable first before removing the SFP
transceiver for any reason. Not removing the fiber cable first can damage the fiber cable,
cable connector or optical interfaces. It is advised not to remove and insert a SFP
transceiver frequently as this may shorten its useful life.
Always use an ESD wrist strap while handling the SFP transceivers since the SFP modules
are static sensitive devices.
Note
The copper 1000BASE-T SFP transceiver port supports 1000Mb only. It is recommended to
use a straight-through RJ-45(4-twisted pair) connection while connecting to any Server/
workstation. While connecting with any Switch/repeater or other device, it is
recommended to use Crossover RJ-45 (4-twisted pair) category 5 or higher cabling. The
maximum length supported on copper 1000BASE-T is 100m (328 ft.).
3.2.5Connecting Fiber Optic Cable to SFP Transceivers
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.Find the Transmit (TX) and Receive (RX) markings on the SFP transceiver to verify the
top side of it. Some of the transceiver marks arrow sign for up.
4.Position the SFP transceiver correctly before insertion, and then insert the SFP
transceiver carefully, until the transceiver connector snap into the place in the socket
connector.
5.Connect the Transmit (TX) port on the Magnum PM to the Receive (RX) port of the
remote device. Connect the Receive (RX) port on the PM to the Transmit (TX) port of the
remote device.
The LINK LED on the front of the PM will illuminate and turn Green, when a proper
connection has been established at both ends (and when power is ON in the unit). If LINK is
not lit or OFF after cable connection, the normal cause is improper cable polarity. Swap
the fiber cables at the PM connector and also check the connectivity on the target device
to remedy this situation.
Reconfigure or reboot both of the devices if required.
If connected properly, you can check via (MultiLink ML810 Managed Edge Switch) firmware
for verifying the validity of SFP Gigabit ports.
DIN-RAIL MOUNTING THE MULTILINK ML810CHAPTER 3: INSTALLATION
NOTE
3.3DIN-Rail Mounting the Multilink ML810
The Multilink ML810 is designed for use in a “factory floor” industrial environment. It is
available with an optional DIN-Rail bracket to mount it securely in a metal factory floor
enclosure, maintained vertically for proper convection cooling of the unit. The Multilink
ML810 requires one DIN-Rail bracket for secure mounting. This may be ordered as Model #
DIN-RAIL-ML810. See a ML810 viewed from the bottom, at the rear, with model DIN-RAILML810 in place on the unit.
The DIN Rail bracket is mounted to the bottom of the ML810 unit, as shown. Four threaded
holes are provided on the bottom of the ML810 for DIN-Rail mounting purposes. The
required four screws are included with the DIN-Rail bracket, and are no.4-40 x 9/32 PHIL.
PAN Head.
To install the ML810 with the DIN-Rail bracket installed, hold the ML810 in the side vertical
position with the bottom out, and with the top moved in toward the DIN-Rail. Position the
DIN bracket over the top of the DIN-Rail. Then, snap the bracket into holding position by
moving the bottom of the ML810 inwards to a vertical position. The DIN-Rail bracket is
heavy duty, and will hold the ML810 securely in position, even with cabling attached to the
unit.
To release the ML810 from the DIN-Rail mounting, simply lift up on the bottom of the unit,
disengaging the DIN rail bracket from the DIN rail. Once the bottom of the ML810 is rotated
out, the DIN-Rail bracket is not engaged and the ML810 can be moved up and out, free of
the DIN-Rail mounting.
The DIN-Rail mounting bracket is optional and needs to be ordered as separate items, e.g
Model # DIN-RAIL-ML810.
3.3.1Mounting Dimensions for ML810 with metal brackets
Each Mangum ML810 is supplied with metal mounting brackets and screws to mount the
unit securely on a panel or wall. It is recommended to mount the ML810 vertically in one of
the two mounting positions available, as shown below, for proper cooling and long-life
reliability. It is also advisable to mount the unit with space for air movement around the top
and the sides, typically a minimum of 1 inch.
Note
The metal brackets supplied, hold the back of the ML810 unit out from the panel or wall
behind it, creating a rear space of about 1/8 inch or 3mm. This allows air circulation and
cooling of the rear part of the case.
For best cooling of the ML810, attach the metal brackets to metal (rather than wood or
plastic). Attaching to metal helps conduct heat away from the ML810 through the metal
brackets and into the metal support structure.
CHAPTER 3: INSTALLATIONDIN-RAIL MOUNTING THE MULTILINK ML810
Since the ML810 has special internal thermal techniques to move the heat generated by
the electronic components inside into the case, the case may be quite warm to the touch
during normal operation.

Closed (NC) contacts to which the user can attach two sets of status monitoring wires at
the green terminal block.
The first NC Alarm Contact is a “Software Alarm” (labeled S/W), operated by user settings in
the MultiLink ML810 Managed Edge Switch firmware. 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
triggers 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 Switch. 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 Switch.
Useful info. about Alarm contacts:
1.There are four terminal blocks (1,2,3,4) provided next to the Console port.
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.
The Alarm Contacts are on the front left area (next to the Console port) of the Multilink
ML810 unit and are green in color as shown in the picture.

The above provided information enables a managed station (a PC or Console terminal) to
connect directly to the switch.
Note
To use the Console port to configure the managed switch, a serial (Null-modem) male to
male cable is required to communicate properly. The Null-Modem (RJ45) cable is optional
and can be ordered from the factory, along with the unit as:
CONSOLE-CBLQD for serial port
CONSOLE-CBLQU for USB port
Note
For Power Substations: In support of the IEEE 1613 Class 2 standard, GCI advises that, for
substation applications, the serial (RJ45) console ports are intended for temporary
connectivity to other equipment such as PCs. Since the console port connection is
temporary, it is excluded from IEEE 1613 packet-loss testing per the 1613 standarddefined test procedure.
This chapter describes the functions and operation of the Multilink ML810 Switch.
4.1Switching Functionality
A Multilink ML810 provides switched connectivity at Ethernet wire-speed among all of its
ports. The Multilink ML810 supports10/100Mbs for copper media and 100Mb separate
traffic domains for fiber ports to maximize bandwidth utilization and network
performance. All ports can communicate to all other ports in a Multilink ML810, but local
traffic on a port will not consume any of the bandwidth on any other port.
The Multilink ML810 units are plug-and-play devices. There is no software configuring
necessary to be done for basic operation at installation or for maintenance. There is an
optional Half / Full duplex mode and 10Mbps or 100Mbps selection for the switched ports
which must be configured through MNS 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 un-interrupted
operation of the network (such as occasional multi-cast packets) is forwarded to all ports.
The Multilink ML810 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 Multilink ML810 units have address table capacities of 8K 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 ML810 Switch automatically keeps up with node
locations.
An address-aging algorithm causes least-used addresses to fall out in favor for frequentlyused addresses. To reset the address buffer, cycle power down-and-up.
AUTO-CROSS(MDIX) AND AUTO-NEGOTIATION, FOR RJ-45 PORTSCHAPTER 4: OPERATION
NOTE
4.2Auto-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 ML810’s copper port to other devices. Operation is according to the IEEE 802.3u
standard.
The Managed ML810’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 ML810 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 ML810 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 ML810 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.
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 ML810’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.
CHAPTER 4: OPERATIONAUTO-CROSS(MDIX) AND AUTO-NEGOTIATION, FOR RJ-45 PORTS
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 ML810 Fast Ethernet
switched ports operating at 100Mb half-duplex, the bit time delay is 50BT.
Multilink ML810 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.
Multilink ML810 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 ML810 Switch port for sufficient time to let the
Switch reduce the buffer space used. When the available free-buffer queue increases, the
Switch will send a “RESUME" packet to tell the transmitter to start sending the packets. Of
course, the transmitting device must also support the 802.3x flow control standard in order
to communicate properly during normal operation.
Note
When in Half-Duplex mode, the ML810 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.
CHAPTER 4: OPERATIONPOWER BUDGET CALCULATIONS FOR ML810 MODULES WITH FIBER MEDIA
4.4Power Budget Calculations for ML810 Modules 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
Multilin products, the following equations should be used:
OPB (Optical Power Budget) = P
where P
Worst case OPB = OPB - 1dBm(for LED aging) - 1dBm(for insertion loss)
Worst case distance = {Worst case OPB, in dBm} / [Cable Loss, in dBm/Km]
where the “Cable Loss” for 62.5/125 and 50/125
and the “Cable Loss” for 100/140 (Multi-mode, 850 nm) is 3.3 dBm/km,
and the “Cable Loss” for 9/125 (Single-mode, 1310 nm) is 0.5 dBm/km (a worst case
industry number)
and the “Cable Loss” for 9/125 (Single-mode, 1310 nm) is 0.4 dBm/km (H4)
and the “Cable Loss” for 9/125 (Single-mode,1550 nm) is 0.25 dBm/km (H5)
= Transmitter Output Power, and PR = Receiver Sensitivity
T
(min) - PR(min)
T
μ
m (M.m) is 2.8 dBm/km,
and the “Cable Loss” for 9/125 (Single-mode, 1550 nm) is 0.2 dBm/km (H6)
The use of either multi-mode or single-mode fiber to operate at 100 Mbps or Gb speed
over long distances (i.e., over approx. 400 meters) can be achieved only if the following
factors are both applied:
• The fiber segment must operate in full-duplex (FDX) mode
• The worst-case OPB of the fiber link must be greater than the fiber cable’s passive
Attenuation. (Attenuation = Cable loss + LED aging loss + Insertion loss + safety
factor).
An important feature of the Multilink ML810 is the use of Port Modules for flexible mixedmedia connectivity to RJ-45 copper and various fiber media. The first four ports (1,2,3 & 4)
of the Multilink ML810 Switches are fixed RJ-45 copper ports with dual-speed 10/100Mbps
auto-negotiating capability. Additionally the switch can accept up to two Port Modules to
provide the user with up to 6 additional ports (10 total) providing a wide selection of
Ethernet copper and fiber media connections with 10, 100 and 1000Mbps capability and
up to 70km.
Each ML810 Port Module (PM) is individually described in the following sections.
4.5.1ML810 Module LED designations
PWR LED= ON, when Power is being supplied to the unit.
The ML810-RJ45 4-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). (For auto-negotiation and MDIX details, see
Section 4.2 in the ML810 User Guide.)
On the model ML810-RJ45 module, there are three LEDs for each port, two integrated into
the connector, and one below the connector. The LK/ACT LED indicates LK (Link) “ready for
operation” on that port when lit. The ACT (Activity) LED indicates receiving Activity on that
port when blinking. The 10/100 LED indicates operation at 100Mb speed when ON and at
10 Mb speed when OFF (when auto-negotiation is not disabled). The F/H LED is ON to
indicate full-duplex operation and OFF to indicate the half-duplex mode. A twisted pair
cable must be connected into an RJ-45 port and the Link (LK) indicator for that port must
be ON (indicating there is a powered-up device at the other end of the cable) in order for a
LK LED to provide valid indications of operating conditions on that port.
Using the MultiLink ML810 Managed Edge Switch firmware, the user may disable autonegotiation and fix the desired operation of each RJ-45 port. The user may select 10Mb or
100Mb speed and full- or half-duplex mode per-port as per user requirements.
Note
For Power Substations: In support of the IEEE 1613 Class 2 standard, GCI advises that, for
substation applications, the RJ-45 ports are intended for connectivity to other
communication equipment such as routers or telecommunication multiplexers installed in
close proximity (i.e., less than 2 meters or 6.5ft) to the ML810. It is not recommended to use
these ports in substation applications to interface to field devices across distances which
could produce high (greater than 2500V ) levels of ground potential rise (GPR) during lineto-ground fault conditions. The ML810 passes the 1613 specifications for zero packet loss
with fiber ports and with RJ-45 ports used as indicated here.

The ML810 is available with the option of having PoE capabilities on the four RJ45 ports in
slot C. This is used in conjunction with ML810P-48VDC to add an additional four PoE ports
to the existing four PoE ports in slot A.
The PoE (Power-over-Ethernet) RJ45 ports are similar to regular RJ45 ports, except they
have the capability of providing power on each port to power up attached PD devices, per
the IEEE802.3af PoE standard. The power-pass-through PoE ports are dependent upon the
-48VDC input power to supply the PD power for these RJ45 (10/100) ports. Each port
supplies up to 15watts to power attached PoE PD devices.
The LEDs on the PoE ports are slightly different compared to regular (non-PoE) RJ45 ports.
When the PoE port is in use, the PoE LED is ON when connected properly to an IEEE 803.af
compliant PD device on that port. When non-PoE devices are connected, the PoE LED is
OFF. Operation of Ethernet data traffic is not affected by PoE. LINK and ACTIVITY LEDS are
combined on the PoE modules into one LED that is marked as L/A.
PoE LEDs Summary
For PoE devices, each RJ45 PoE port supports only 802.3af complaint devices. The PoE LED
is ON when the attached PD is drawing power from the port. The power is supplied on the
data pairs, per IEEE802.3af PoE standard.
For non-PoE devices connected, the PoE port will act as a normal RJ45 port and the PoE
LED is OFF. No power is sent out from the port.
The PoE ports in Magnum 6K’s with 48VDC power input act as a pass-through, so the
48VDC power input source to the Multilink ML810 must be strong enough to provide power
to the 6K switch and to all 4-RJ45 ports with PD devices connected (up to 15 watts per PoE
port).
In the case where the 48VDC power in not internally connected to the POE port pins and no
power is coming to the PoE ports for some reason, all the PoE port LEDs are ON
simultaneously to indicate a trouble condition. The ports will still operate properly for data
traffic to non-PoE devices.
4.5.21 ML810 (H7), 2 x Gigabit RJ45 (Slot B)
The ML810 (H7), 2-port Copper Gigabit module provides two fixed 10/100/1000Mb RJ45
ports in slot B.
There are two LEDs provided for each Gigabit port. Each Copper Gigabit port has LEDs that
indicate L/A (Link/Activity), 10, 100 and 1000Mbps speed (set to AUTO by default).
All Magnum Ethernet products are designed to provide reliability and consistently high
performance in all network environments. The installation of a Multilink ML810 Switch is a
straight forward procedure. The operation is also straightforward and is discussed in
Section 4.0 of this ML810 User Guide.
Should problems develop during installation or operation, this section is intended to help
locate, identify and correct these types of problems. Please follow the suggestions listed
below prior to contacting your supplier. However, if you are unsure of the procedures
described in this section or if the Multilink ML810 Switch is not performing as expected, do
not attempt to repair the unit; instead contact your supplier for assistance or contact GE
Customer Support.
4.6.1Before Calling for Assistance
1.1.If difficulty is encountered when installing or operating the unit, refer back to the
Installation Section of the applicable chapter of this manual. Also check to make sure
that the various components of the network are interoperable.
2.Check the cables and connectors to ensure that they have been properly connected
and the cables/wires have not been crimped or in some way impaired during
installation. (About 90% of network downtime can be attributed to wiring and
connector problems.)
3.Make sure that power is properly attached to each Multilink ML810 Switch unit. Use
the PWR LEDs to verify each unit is receiving power.
4.If the problem is isolated to a network device other than the Multilink ML810 Switch
product, it is recommended that the problem device be replaced with a known good
device. Verify whether or not the problem is corrected. If not, go to Step 5 below. If
the problem is corrected, the Multilink ML810 Switch and its associated cables are
functioning properly.
5.If the problem continues after completing Step 4 above, contact GE Digital Energy.
4.6.2When Calling for Assistance
Please be prepared to provide the following information.
1.A complete description of the problem, including the following points:
• The nature and duration of the problem;
• Situations when the problem occurs;
• The components involved in the problem;
• Any particular application that , when used, appears to create the problem;
2.An accurate list of GE product model(s) involved, with serial number(s). Include the
date(s) that you purchased the products from your supplier.
3.It is useful to include other network equipment models and related hardware,
including personal computers, workstations, terminals and printers; plus, the various
network media types being used.
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 section 1.5.6: Setting the IP Parameters. 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:
ML810> show ipconfig
IP Address:3.94.247.41
Subnet Mask:255.255.252.0
Default Gateway: 3.94.244.1
ML810>
To verify the IP address using the EnerVista Secure Web Management software,
Select the Administration > System menu item to view.
IP ADDRESS AND SYSTEM INFORMATIONCHAPTER 5: IP ADDRESSING
Edit the IP address information.
Besides manually assigning IP addresses, there are other means to assign an IP address
automatically. The two most common procedures are using DHCP and bootp.
CHAPTER 5: IP ADDRESSINGIMPORTANCE OF AN IP ADDRESS
5.2Importance of an IP Address
5.2.1DHCP 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
5.2.2bootp 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:
bootp service is not started as a default and has to be enabled. A sample
bootp software will look up the database and update the IP address
ML810 is a user-defined symbolic name for the switch.
ht is the hardware type. For the MultiLink family of switches, set this to ether (for
Ethernet). This tag must precede the
ha is the hardware address. Use the switch's 12-digit MAC address.
ip is the IP address to be assigned to the switch.
sm is the subnet mask of the subnet in which the switch is installed.
ha tag.
Each switch should have a unique name and MAC address specified in the
bootptab table
entry
5.2.3Configuring DHCP/bootp/Manual/AUTO
By default, the switch is configured for auto IP configuration. DHCP/bootp/manual can be
enabled with the command line interface by using the
following syntax:
set bootmode=<dhcp|bootp|manual|auto> bootimg=<enable|disable>
bootcfg=<enable|disable>
bootimg argument is only valid with the bootp type. This option allows the switch to
The
load the image file from the bootp server. This is useful when a new switch is placed on a
network and the IT policies are set to load a specific image which is supported and tested
by IT personnel.
IMPORTANCE OF AN IP ADDRESSCHAPTER 5: IP ADDRESSING
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 conf igurations are loaded from a centralized
bootp server
The following example changes the boot mode of the switch:
ML810# set bootmode type=bootp bootimg=enable bootcfg=disable
Network application image download is enabled.
Network application config download is disabled.
Save Configuration and Restart System
ML810#
Alternatively, the DHCP/bootp/manual can be enabled through the EnerVista Secure Web
Management software as shown below.
Select the Administration > System menu item.
Click Edit.
Alternatively, select items in the Administration > Set menu to
individually modify the boot mode, date and time, log size, etc.
CHAPTER 5: IP ADDRESSINGIMPORTANCE OF AN IP ADDRESS
5.2.4Using Telnet
After the changes are completed for each section, click OK to
register the changes.
Note that if the IP address is changed, the
http session has to be restarted with the new IP
address.
The telnet client is enabled on the ML810. The ML810 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 ML810. 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
section 1.5.8: User Management, for details.
Multiple telnet sessions started from the CLI interface or the command line are serviced by
the ML810 in a round-robin fashion (that is, one session after another). If one telnet session
started from an ML810 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.
IMPORTANCE OF AN IP ADDRESSCHAPTER 5: IP ADDRESSING
The show console command can show the status of the telnet client as well as other
console parameters. The following example reviews the console parameters with the
Users can telnet to a remote host from the MultiLink family of switches using the following
syntax.
telnet <ipaddress> [port=<port number>]
The default port for telnet is 23.
To start a telnet session through the EnerVista Secure Web Management software,
Select the Administration > Telnet menu item.
show
The default port for telnet is 23.
The ML810 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 ML810 supports the following two commands:
CHAPTER 5: IP ADDRESSINGIMPORTANCE OF AN IP ADDRESS
NOTE
For example:
ML810# user
ML810(user)## useraccess user=peter service=telnet enable
Telnet Access Enabled.
ML810(user)## exit
ML810# show session
Current Sessions:
SL# Sessn Id Connection User Name User Mode
1 1163.10.10.14 manager Manager
2 2163.11.11.1 peterManager
3 3163.12.12.16 operator Operator
ML810# kill session id=3
Session Terminated
ML810#
In the above example, the user with username “peter” is given telnet access. Then multiple
users telnet into the switch. This is shown using the
operator session is then terminated using the
show session command. The user
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.
To be compliant with IT or other policies the console parameters can be changed from the
CLI interface. This is best done by setting the IP address and then telnet over to the switch.
Once connected using telnet, the serial parameters can be changed. If you are using the
serial port, remember to set the VT-100 emulation software properties to match the new
settings.
The serial port parameters are modified using the
following syntax:
set serial [baud=<rate>] [data=<5|6|7|8>] [parity=<none|odd|even>] [stop=<1|1.5|2>]
[flowctrl=<none|xonxoff>]
Where <rate> = standard supported baud rates.
set serial command with the
Note
5.3.2System Parameters
Changing these parameters through the serial port will cause loss of connectivity. The
terminal software parameters (e.g. HyperTerminal) will also have to be changed to match
the new settings.
To see the current settings of the serial port, use the

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
It may be necessary to set the day, time or the time zone manually. This can be done by
using the
syntax:
To set the time to be 08:10 am in the -5 hours from GMT (Eastern Standard Time) and to set
the date as 11 May 2005, the following sequence of commands are used.
The syntax for other date and time commands are:
The following command sequence sets the daylight location:
The date and time can only be set through the command line interface software.

5.3.4Network 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
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
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.
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 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.
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:
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
ML810# saveconf mode=tftp 3.94.240.9 file=ML81 0se t
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

instead of
ftp, tftp, or xmodem commands. It is advised to begin using these commands
saveconf and loadconf.
5.4.2Config file
Multilink software can now 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 in Multilink software 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:

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 Digital
Energy. Use the old format only if there are multiple MultiLink switches on the network
running different versions of software. GE Digital Energy recommends upgrading all
switches to the most current software release.
To ease the process of uploading and executing a series of commands, the ML810 can

5.4.5Script 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 MNS.
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 Digital
Energy, 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.
In the above example, note that all the commands are CLI commands. This script provides
an insight into the configuration of GE MultiLink switches settings. GE Digital Energy, 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.
5.4.6Saving and Loading – EnerVista Software
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.
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
or
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.
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 ML810 image from switch to the
server (or from the server to the switch). The “Image Upload” option is
commonly used to upgrade the ML810 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 ML810 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 ML810.
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
The following figures illustrate saving changes made after adding an SNTP server. This is
done by clicking on the Save icon to save current configuration
5.4.7Host Names
Instead of typing in IP addresses of commonly reached hosts, the ML810 allows hosts to be
created with the necessary host names, IP addresses, user names, and passwords.
Use the Configuration > Access > Host menu to create host entries
