1.5 General Safety
1.5.1 Cautions and Warnings
Disconnect all power from electronic devices before servicing. Some equipment may have
multiple power cords requiring disconnection.
1.5.2 Laser Safety
WARNING: Fiber optic equipment may emit laser or infrared light that can injure your
eyes. Never look into an optical fiber or connector port. Always assume that fiber optic
cables are connected to a laser light source.
CAUTION: Do not install or terminate fibers when a laser may be active.
WARNING: Never look directly into a live optical fiber. Always wear appropriate laser
safety glasses when working with open fiber cables that might be connected to an
operational laser transmitter. Direct open fibers ends away from faces.
CAUTION: Use of controls or adjustments or performing procedures other than those
specified herein may result in hazardous radiation exposure.
If a fiber optic laser device output is recognized as a higher than Class 1 product (Class 1M, for
example), the device is evaluated, labeled, and certified by TUV. Class 1 and 1M outputs are
not considered hazardous, but laser safety practices should always be observed.
A fiber optic transceiver emits either single-mode or multi-mode light into a fiber optic strand.
Take the following precautions when handling optical fibers.
• Wear safety glasses when you install optical fibers.
• Be aware of the risk of laser radiation exposure.
• Because transmitted light is invisible to the human eye, always assume that a fiber optic
transceiver is on and operational.
• Never look directly into a beam (TX part of a transmitter) or open fiber ends. The
invisible light can damage your eyes.
• Place optical fibers in a safe location during installation.
• Protect optical fiber connectors with clean dust caps for safety and cleanliness.
• Follow the manufacturer instructions when using optical test equipment.

1.5.3 Static Electricity
Eliminate static electricity in the workplace by grounding operators, equipment, and devices
including components and computer boards. Grounding prevents static charge buildup and
electrostatic potential differences. Transporting products in special electrostatic shielding
packages reduces electrical field damage potential.
1.5.4 Workplace Preparation
A safe and effective workplace provides the following items.
•
•
•
ESD protective clothing/smocks: Street clothing must not come in contact with components
or computer boards since the various materials in clothing can generate high static
charges. ESD protective smocks, manufactured with conductive fibers, are recommended.
Electrostatic shielding containers or totes: These containers (bags, boxes, etc.) are made
of specially formulated materials, which protect sensitive devices during transport and
storage.
Antistatic or dissipative carriers: These provide ESD protection during component
movement in the manufacturing process. It must be noted that antistatic materials alone
will not provide complete protection. They must be used in conjunction with other methods
such as totes or electrostatic shielding bags.
•
•
Dissipative tablemat: The mat should provide a controlled discharge of static voltages and
must be grounded. The surface resistance is designed such that sliding a computer board
or component across its surface will not generate more than 100 V.
Operator grounding: Keep a wrist strap or ESD cuff in constant contact with bare skin with
a cable for attaching it to the ESD ground. The wrist strap drains off the static charge of the
operator. The wrist strap cord has a current-limiting resistor for personnel safety. Wrist
straps must be tested frequently to ensure that they are undamaged and operating
correctly. Use special grounding heel straps or shoes when a wrist strap is impractical.
These items are effective only when used in conjunction with a dissipative floor.
•
ESD protective floor or mat: The mat must be grounded through a current-limiting resistor.
The floor or mat dissipates the static charge of personnel approaching the workbench.
Special conductive tile or floor treatment can be used when mats are not practical or cause
a safety hazard. Chairs should be conductive or grounded to the floor with a drag chain.

2 Product Overview
The EM316-2SFP transparent converter contains two MSA compliant SFP sockets connected back-
to-back. No components on the EM316-2SFP board are connected to the data path, so the module is
considered transparent. Supported speed ratings range from 100 Mbps up to 2.7 Gbps where speed-
matching or multi-rate SFPs are required in both ports. This EM316-2SFP converter is hot-pluggable,
and it is managed through the Fiber Driver management bus from a network management module.
The SFP sockets support a wide range of SFP modules available from MRV to address any network
situation.
• Single-mode
• Multi-mode
• Multi-rate
• Single fiber bi-directional
• Coarse Wave Division Multiplexing (CWDM)
• Dense Wave Division Multiplexing (DWDM)
• Copper 10/100
2.1 Management features
2.1.1 LIN
Link Integrity Notification (LIN) notifies connected equipment and network management systems
if the EM316-2SFP module detects a loss of receive signal on one of its SFP ports. The loss of
receive signal may be caused by a cable break, disconnection, remote power loss, or a variety
of other events. With LIN enabled on a module, the loss of receive signal is propagated
downstream to the remote end, notifying the remote device of a fault in the circuit. This
communication ensures that connected equipment is notified of a link fault. The connected
device, such as a switch or router, can then activate preconfigured, link-state dependent
redundancy mechanisms, and properly react to link conditions. This feature is extremely
important in fault-tolerant network designs. To avoid a possible “deadly embrace” condition
requiring operator intervention, ensure that neither remote device allows disabling of its SFP
transmitter.
LIN works in unmanaged and managed modes, and it applies globally to the module rather than
to individual ports. Enable LIN on the module to allow remote control of this feature through
network management.
LIN is not supported in a mixed copper and fiber environment.

EM316-2SFP User Guide
2.1.2 Loopback
The EM316-2SFP module supports loopback either by DIP switch setting or controlled through
the CLI or SNMP software settings. For software control the Loopback DIP switch must be set
to OFF. It the Loopback switch is ON, it cannot be over-ridden by software.
Loopback is one way to assure that the fiber optical communication path is valid and error free.
Packets sent over a short-circuit link should be received by the sender without any modification
to the original data packet.

4 Module Management
Most Fiber Driver modules, including the EM316-2SFP, may be managed by a Fiber Driver network
management (NM) module installed in the same chassis.
The EM316-2SFP module may be managed by either the EM316NM-5 or EM316LNXNM-OT Network
Management (NM) modules.
The NM module installs in the same chassis as the managed modules. It provides management for
the 2SFP module and other compatible Fiber Driver modules resident in the chassis. Refer to specific
module documentation to determine compatibility with a specific NM.
Although the factory settings are appropriate for most installations, network management through an
NM module is highly recommended. Network environments are unpredictable, and Fiber Driver
network management is a critical tool for proactive administration as well as for reduced operating
expenses.
The NM provides a command line interface (CLI), accessible either through a local serial port and
console or from the IP network using a terminal emulation environment. Some CLI commands specific
to the 2SFP module in a managed environment are discussed in this section. Refer to the appropriate
NM documentation (EM316NM-5 or EM316LNXNM-OT) for further details regarding the interface and
commands specific to your installation.
The network management module also provides Simple Network Management Protocol (SNMP)
support to allow control through any industry standard network management system (NMS). To
maximize the graphical remote management control of Fiber Driver modules, MRV offers
MegaVision® Pro. It is a unique and full-featured NMS with graphical user interfaces (GUI) for all
managed MRV network components including Fiber Driver. A limited version of MegaVision called
“Configurator” is available for trial through the MRV website (http://www.mrv.com). Refer to MegaVision
Pro documentation for more information on the benefits offered with the product.

EM316-2SFP User Guide
4.1 Remote Command Line Interface (CLI) Setup
The NM has at least one Ethernet port, which is typically used to connect to a Local Area Network
(LAN). The factory default IP address is 192.168.14.201 with netmask 255.255.255.0, sometimes
written as 192.168.14.201/24 to show the 24 bits masked for subnetting. The default gateway
address is 192.168.14.1/24.
From the network, connect to the NM IP address using telnet or SSH (secure shell) to open the
command line interface (CLI). Telnet services are disabled by default on the EM316LNXNM-OT,
but they may be enabled for additional CLI access. SSH is not available on the EM316NM-5.
4.2 Serial Command Line Interface (CLI) Setup
Each NM has an RS-232 interface that is used for serial communications to the CLI. This
connection is recommended for network setup. Besides configuration simplicity, it offers the
advantage of “out-of-band” management for greater network autonomy.
Attach the serial RS-232 cable to the PC or terminal device. Configure terminal emulation software
with the parameters described below.
4.2.1 EM316NM Serial Console Setup

4.4 EM316LNXNM-OT Command Line Interface (CLI)
The EM316LNXNM-OT provides command line interface (CLI), SNMP, and graphical
administration options for a Fiber Driver chassis system. This section introduces the CLI for the
Linux-based network management (EM316LNXNM-OT) module.
The commands for EM316NM and EM316LNXNM-OT management are specific to each module.
The EM316LNXNM-OT management module also includes MegaVisionJ, a built-in graphical
interface to manage only the Fiber Driver chassis system controlled by the specified NM. This
graphical system is accessible from any standard Java-enabled web browser that can reach the IP
address assigned to the EM316LNXNM-OT. MegaVisionJ allows remote management of the entire
Fiber Driver chassis system and compatible modules.
Some commands applicable to the 2SFP modules are illustrated in this manual. The box below
lists a few sample commands addressed in this document. Refer to EM316LNXNM-OT documents
for more detail.

4.4.2 CLI Navigation
The CLI uses five operational contexts: login, configuration, chassis, slot, and port. Only the
login context is not considered a configuration mode. The system prompt includes a string to
indicate the current operational context, as illustrated in the example below. The “#” character
ends the prompt string, and a space separates the command from the prompt.
Each navigation command in the box below is bold for emphasis in print only.
fiberdriver# configure terminal
fiberdriver(config)# chassis 1
fiberdriver(chassis/1)# slot 1.4
fiberdriver(slot/1.4)# port 1.4.2
fiberdriver(port/1.4.2)# next
fiberdriver(port/1.4.3)# exit
fiberdriver(config)# exit
fiberdriver#
These contexts are not entirely hierarchical, but the three hardware-specific contexts do follow a
structure that reflects the physical device relationships. The chassis contains slots (modules)
which in turn contain ports.
Enter the configuration context with the “configure terminal” command. Any hardware
context may be reached directly from the config context or any other hardware context. For
example, there is no need to pass through the chassis context to reach the slot or port contexts.
The next command is a short-cut for navigating to the hardware context following the current
context and at the same level. In the box above, the port value in the prompt increments from 2
to 3 to indicate this context change.
Operations on the larger component may sometimes also apply to the smaller components
contained in the larger target device. Refer to EM316LNXNM-OT documentation or use the CLI
help feature “?” for more information about CLI context navigation.

4.4.3 Login Context Commands and Examples
The login context refers to the only CLI state not considered a configuration context. Commands
in this context are generally for system status monitoring. Use the “?” and “list” commands at
the fiberdriver #prompt to display the list of command line options. These help commands
are shown in the slot and port command illustrations later in this section.
A few login context commands are illustrated in this section.

4.4.4 Configuring System Parameters
Enter "configuration" mode, as shown below, to configure the system parameters
fiberdriver# configure terminal
Note that each command is completed with the <CR> or <Enter> key, which is not printable.
Once the mode is changed, the prompt also changes. Change the SUPER user password using
the "username" command.
fiberdriver(config)# username admin password <new password>
Set the IP configuration using the "ip" command group. Set IP address and IP mask information
using the following command.
fiberdriver(config)# ip interface 169.254.88.200/16
The IP address (169.254.88.200) and the netmask (16) are examples only. Use the IP address
and netmask appropriate for the EM316LNXNM-OT on your network. Classless Inter-Domain
Routing (CIDR) notation is used to specify the address (169.254.88.200) and mask (16)
corresponding to 255.255.0.0.
Set specific gateway information using the following command:
fiberdriver(config)# ip default gateway 169.254.88.1
The IP information configured does not load until restarting the system or using the command:
ip interface update
Use the following command to save the configuration into permanent (non-volatile) storage:
fiberdriver(config)# write file
fiberdriver(config)# exit
The system does not automatically save configurations to permanent storage. Use the write
filecommand to save a configuration before restarting the system. Now the IP configuration is
complete. The default SNMP community names are "public" for read and "private" for write.
Use the description command to change names of the chassis, slot, and port. Use the show
command to verify the change. Chassis names are limited to nine characters.

4.4.6.1 “?”
The “?” is a special help character in the EM316LNXNM-OT command line. In previous
releases, the “?” character did not echo to the display when typed. Beginning in version 4.0,
the “?” displays as other commands do. Results of the help request are displayed
immediately to the monitor.
The box below shows the output of the “?” typed alone on the command line in the slot-level
configuration context. In other contexts, the display is different to reflect the commands
available from the current prompt. Navigate to each operational context and type “?” at the
prompt to become familiar with these commands in your environment. Also notice the
different help output in the slot-level context of a different Fiber Driver module type. The box
displayed below is specific to 2SFP modules.

The “?” may also be used in two ways after a command typed at the prompt in any context.
When typed immediately after a command line entry with no space separating it from the
command, the “?” displays a list of commands that match the preceding string and a
description of each matching command function. When a space separates the command
string from the “?”, the display shows the first matching command and a list of the options for
the next required parameter on the command line.
Read more about the “?” help character in the EM316LNXNM-OT User Guide. There is no
substitution for practicing the command to become familiar with its behavior.

EM316-2SFP User Guide
The boxes below illustrate two common parameters used with the showcommand.
Default settings are listed in the show defaults command output. These parameters
reflect the module boot configuration which is determined by DIP switches and firmware
programming. All lines in this display begin with “!” to indicate that they are comments for
information only.
fiberdriver(slot/1.1)# show defaults
slot 1.1
! description EM316-2SFP at 1.1
fiberdriver(slot/1.1)#
The show config command displays the active environment settings currently in the
operational context. The lines beginning with “!” are comments added for clarity in the CLI
display only. The comment lines ending with “:” are headings that describe the settings listed
in this display.
fiberdriver(slot/1.1)# show config
slot 1.1
! Configured parameters that override defaults:
! Configured parameters that match defaults:
! Parameters that will follow defaults:
! description EM316-2SFP at 1.1
fiberdriver(slot/1.1)#
The default parameter values are constant for each module, but can change to reflect DIP
switch settings. Changes to these parameter values are reflected in the show config
command output. Restoring the default values returns the module to its original operating
state. Preserve changes made to the configuration for use in future CLI sessions and beyond
a reboot by writing them to the startup-config file as described later in this section.

4.4.7 Port Context Commands and Examples
Command examples in this section are applied in the port-level context. The box below shows
the command to navigate to a specific port context from the login context.
fiberdriver# configure terminal
fiberdriver(config)# port 1.3.2
fiberdriver(port/1.3.2)#
4.4.7.1 “?”
The “?” command, used alone on the command line, lists the commands available in the
current operational context.
The “?” may also be used in two ways following a command word typed at the prompt in any
context. When typed immediately after a command line entry with no space separating it
from the command, the “?” displays a list of commands that match the preceding string and a
description of each matching command function. When a space separates the command
string from the “?”, the display shows the first matching command and a list of the options for
the next required parameter on the command line.
Read more about the “?” help character in the EM316LNXNM-OT User Guide. There is no
substitution for practicing the command to become familiar with its behavior.
