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.
• Always assume that fiber optic cables are active because transmitted light is invisible to
the human eye.
• 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 sanitation.
• Follow the manufacturer instructions when using optical test equipment.

1.5.3 Laser Device Classifications
Laser devices of class 1M, class 2, class 2M and class 3R
Precautionary measures are only necessary to avoid a permanent direct looking into the laser
beam; for classes 2 and 2M is a momentary (0.25 sec.) irradiation in a wave length range
between 400 nm and 700 nm, as it may occur when you accidentally look into the beam, not
considered to be dangerous. However, you should not level the laser beam intentionally at
people. The use of optical aids (e.g. binoculars) together with laser devices of the classes 1M,
class 2M and class 3R may increase the danger for the eyes

1.5.4 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.
1.5.5 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 Introduction to EM316EDFA Optical Amplifiers
The fiber optic amplifier module is used to increase an optical signal for extended range or clarity
without electrical conversion circuitry. The MRV EM316EDFA modules boost an optical input up to 20
decibels. The amplifier also has a bandwidth of 40 nm, making it suitable for use in wavelength
division multiplexing (WDM) applications as an optical spectral amplifier. The module may be
controlled from the network through the MRV EM316LNXNM-OT Network Manager Module.
Optical amplifiers operate in different modes, depending upon their position in the optical link. The
EM316EDFA is available in two configurations to fill the necessary roles in your network.
C-band optical amplifier booster
C-band in-line optical amplifier
C-band pre-amplifier
EM316EDFA-BR
EM316EDFA-LPR
The example below illustrates how the EM316EDFA optical amplifiers fit into an optical link.

2.1 Features
The EM316EDFA board can run in standalone mode without any input from a management
module. The EM316EDFA analog input power determines the output power because the module
runs at a fixed gain.
EM316EDFA status is reported through SNMP through a network management module as well as
by LEDs on the front panel.
The green “SD” LED on the front panel indicates input greater than the thresholds corresponding to
the EDFA module type, as indicated in the table below.
EM316EDFA-BR
EM316EDFA-LPR
-8 dBm
-30 dBm
A green LED at front panel (Optical Output) indicates output power greater than -10 dBm.
The module temperature is measured from 0 o C to 70o C and reported to management. To protect
against excessive heat, the laser shuts down when measured temperature reaches 70o C.

5 Module Management
Most Fiber Driver modules, including the EDFA amplifier family, may be managed by a Fiber Driver
network management (NM) module installed in the same chassis.
The EDFA amplifier modules may be managed by the EM316LNXNM-OT Network Management (NM)
module.
The NM module installs in the same chassis as the managed modules. It provides management for
the EDFA amplifier module and other compatible Fiber Driver modules resident in the chassis. Refer
to specific module documentation to determine compatibility with a specific NM.
Factory settings work in most EDFA amplifier installations, but network management through an NM
module is recommended for local and remote- system status monitoring. 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 EDFA amplifier modules in a managed environment are discussed in this section. Refer to the
appropriate NM documentation (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.

5.1 Serial Console Interface
After the network management (NM) module is installed, power up the chassis and attach the
serial RS-232 cable to the PC or terminal device. Configuring terminal emulation software on the
PC is beyond the scope of this document. The components below may be ordered from MRV.
• Adapter (part number 350-0308 REV-B MRG/20028-2)
• Cable (part number 151-3028 REV-F AI 04/04)
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.
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.
Configure the EM316LNXNM-OT RS-232 serial parameters with the following values.
• • 38400 baud
• • 8 data bits
• • 1 stop bit
• • no parity

5.2 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.
EM316LNXNM-OT management commands 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 EDFA amplifier modules or host chassis are illustrated in this
manual. The box below lists a few of the sample commands addressed in this document. Refer to
the Table of Contents for a list of commands addressed here, and refer to EM316LNXNM-OT
documents for more detail.

5.2.2 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.

5.2.3.5 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 file command 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.

5.2.5.1 “?”
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 EDFA modules. The same command list displays for slot 1.4,
except that the “reset” (highlighted) command is not available.

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.

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.

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/1.4)#
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.
