PN 1275005-100 Rev E6 5
1.8. Laser Safety
Do not open laser devices for service. Removing the cover may cause exposure to harmful laser
beams. Return defective laser devices to the vendor for service.
Un-terminated connectors or fiber cable ends may emit invisible laser radiation. To avoid eye
injury, do not view them within 100 mm or directly with optical instruments such as eye loupes,
magnifiers, or microscopes. The amplified laser output can dramatically increase eye hazard.
This equipment is intended for use with Class 1 pluggable (SFP, SFP+, XFP, QSFP, GBIC) fiber
optic transceivers with a label indicating the following specifications:
1. Classification as a Class 1 Laser product
2. Compliance with Food and Drugs Administration Center for Radiological Health (FDA
CDRH) performance standards, 21 CFR 1040.10 (except deviations noted in Laser Notice
#50, 6/24/2007)
3. Certification from Nationally Recognized Testing Laboratory (NRTL), CSA, or TUV
Some fiber optics modules (EM316EDFA) may contain Class 1M levels of invisible laser
radiation. Class 1M equipment must be installed in a restricted location that is accessible only
to authorized personnel with laser safety training.
WARNING:Laser products labeled as Class1M may have internallaser diodes containing Class
3B lasers.
Caution: use of controls, adjustments, or procedures not specified by the manufacturer my result
in hazardous radiation exposure.
1.9. Aggregated Power
Access to the fiber ends and connections constitutes potential risks with live laser transmissions. Although
individual components may produce output within Class 1 parameters, some devices combine signals that
collectively exceed Class 1 hazard level of 10 dBm. Measure all risk potentials for both skin and retinal
hazards when working with equipment such as Fiber Driver WDM add/drop and multiplex/de-multiplex
devices.
IEC 60825-2, D.5.1 - Aggregated Wavelengths on a Fiber (excerpt)
When more than one wavelength is combined on the same fiber as in a WDM system, then the hazard
level depends on aggregated power levels. Hazards are cumulative for common wavelengths used in
optical communications.
Refer to the IEC document quoted above for more information on laser safety.
1.10. Input Thresholds
Receiver inputs are sensitive to power levels, particularly on small pluggable transceivers. Observe
component thresholds for optimal operation, to avoid damage, and to maintain warranty support.

EM316LNXNM-OT Network Managers
PN 1275005-100 Rev E6 6
Chapter 2. Network Managers
...introduction to the Linux-based network managers
2.1. The EM316LNXNM Modules
The EM316LNXNM network managers control either the Fiber Driver (FD) or the Media Cross Connect
(MCC) network platforms. The EM316LNXNM models are specifically configured for each product line,
as shown below.
EM316LNXNM-OT Fiber Driver manager (two SFP sockets and embedded MegaVisionJ GUI)
EM316LNXNM-MCC MCC manager (no SFP sockets and embedded PathFinder GUI)
The MCC configuration is bundled and distributed as an integral part of each MCC chassis. The Fiber
Driver configuration is ordered as a separate module to allow for many unmanaged and remotely
managed CO/CPE applications. Default settings may work for many applications, but management allows
customization to optimize installations or to use the powerful features of the MRV network devices.
Examples and figures may show either module configuration, but management features are consistent
between the modules except as stated.
2.2. Features
EM316LNXNM modules provide powerful and extensive tools for managing Fiber Driver and MCC
systems. The management module firmware is based on a Linux kernel for security and extensibility.
• Local and remote administration interface for Fiber Driver and MCC platforms
• Linux-based onboard software for extensible, open-source configuration
• Serial port and IP network interface access with Telnet or SSH terminal services
• Native command line interface (CLI) and SNMP support
• Field upgrade support to expand software features with limited downtime
• Extensive management tools and environment controls for users, groups, and administration
• Custom graphical user interface (GUI) support with MegaVision
• PathFinder graphical user interface (GUI) support (MCC only)
• Application programming interface (API) for automated and scripted administration (MCC only)
• Additional SFP interface sockets for more network expansion (Fiber Driver only)
• Cluster Discovery Protocol for groups of managed systems (Fiber Driver only)
• Synchronization of commands with devices (flush) and software (sync)

EM316LNXNM-OT Network Managers
PN 1275005-100 Rev E6 7
2.3. Management Environments
The NM module provides a command line interface (CLI) management environment that is accessible
locally through the RS-232 serial console port or remotely through the RJ-45 Ethernet port using SSH
or Telnet protocols. The CLI environment and some of the available CLI commands are addressed in
dedicated manual sections. Refer to EM316LNXNM command line help for specific command syntax and
usage not included in this document.
The EM316LNXNM module also provides Simple Network Management Protocol (SNMP) support that
allows control through any industry standard network management system (NMS). To maximize the
graphical remote management control of MRV modules, MRV offers MegaVision® Pro. It is a powerful
NMS with unique graphical user interfaces (GUI) for managed MRV network components including Fiber
Driver and MCC. A limited version of MegaVision called “Configurator” is available for trial through
http://www.mrv.com. Refer to MegaVision Pro documentation for more information on the benefits and
options for graphical management.
The firmware of the EM316LNXNM module includes a graphical network manager: MegaVisionJ for
Fiber Driver and PathFinder for MCC. Each graphical user interface (GUI) is accessible through a Java-
enabled HTTP browser at the IP address configured on the module. The embedded GUI provides access
to all the necessary management features available for one managed system only.
An Application Programming Interface (API) is available for customized automation and software control
of managed systems. Refer to MRV technical support for details not included in this document.

Chapter 3. Module Installation
...unpacking and installing hardware
3.1. The EM316LNXNM Network Manager
The FD NM (EM316LNXNM-OT) is a standard Fiber Driver module that occupies one slot in a Fiber
Driver chassis. It is not bundled with any chassis because network management is optional for some Fiber
Driver platform solutions.
The appropriate MCC network manager model is bundled as part of each MCC modular chassis, but it is
also available as a replacement or spare.
3.2. Unpacking the NM Module
This information is primarily for the FD NM that is sold independently, but the general information below
can also apply to the spare MCC NM. Follow the steps below as illustrated in the figure.

3.4. NM Module Installation
Fiber Driver modules including the FD NM are hot-swappable in a powered Fiber Driver chassis. A
#1 Phillips and a 5.0 flat-tip screwdriver may be useful when working with Fiber Driver chassis and
components.
If it does become necessary to handle the MCC NM, refer to the guidelines described below for the Fiber
Driver NM with allowances for the illustrated Fiber Driver chassis examples.
Follow all guidelines to eliminate static electricity while handling the module and other electronic devices.
Follow all safety suggestions in this manual and guidelines for all related equipment.
Step 1 Remove the blank panel or old module from the target chassis slot. Unfasten the mounting screws
with a 6-inch Phillips screwdriver, or disengage any thumb screws by hand.
Remove the required blank panels
To comply with FCC regulations and for optimal cooling air flow, a cover panel or a module must cover
everychassis slot.To limit externalsignals, nochassis slot shouldremain openwhen the unitis operational.
Secure modules and panels with appropriate screws for grounding and further compliance.
Step 2 Install the module into a Fiber Driver chassis by aligning the edge of the circuit board with the rail
of the chassis. Tighten the thumbscrew by hand, and do not over-tighten.
Module installation (not all chassis are shown)
Handle modules by the edges to avoid damaging any components. Follow ESD precautions in this manual
and electrical component guidelines. Push the module securely into the chassis slot your thumbs. Do not
use excessive force, but make sure the module connector is fully inserted in the chassis. Secure the module
by hand using the thumbscrew.

3.5. Fiber Optic Transceivers Care
Optical devices use a variety of cables, connectors, transceivers, and other components that require special
handling care.
Follow all ESD precautions listed at the front of this manual.
3.5.1. Cleaning Fibers
Fiber optic components and cables are very sensitive to dirt, dust, and mishandling, especially in high-
speed networks. Dirty or mistreated fiber may cause errors and degradation of signal quality that affect
network performance or module functionality.
3.5.1.1. Cleaning Supplies
1. Optical cleaner cartridge
2. Can of compressed air
Cleaning cartridge
3.5.1.2. Cleaning Procedure
Follow the procedure below to clean optical transceivers before each cable installation.
1. Blow a stream of compressed air on the fiber ends while the caps are in place.
2. Remove the caps, and blow the ends of the fibers again.
3. Follow the cartridge instructions to clean the ends of the fibers.

3.5.2. Working with Fiber Optic Transceivers
The pluggable optics modules
used in the EM316xx products
are extremely portable, and
consequently may be easily
mistreated. If optical transceivers
have not been protected
against dust, remove the dust
caps and clean them with
1.25 millimeter cleaners. Optical transceiver cleaners
3.5.2.1. Cleaning Fiber Optic Transceivers
Use the 1.25mm cleaners shown above and the steps below to clean optical transceivers.
1. Insert the 1.25mm cleaner into the optical transceivers
2. Turn ¼ turn
3. Remove the 1.25mm cleaner and discard
4. Repeat the process
Install optical cables with as little fiber stress as possible. Stretching or bending optical fibers can damage
them and affect performance.
