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.

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.

chassis. Install the EM316xx module into a single slot or multiple slot chassis by aligning the edge  
of the card with the rail of the chassis and hand-tighten the thumb screw.  
The thumb screw points to the left in the BU-1, BU-2, BU-3, and BU-4 chassis. The thumb screw  
points to the bottom in the BU-16 chassis.  
Tools  
6-inch Phillips screwdriver (for some module screws)  
6-inch flat-tip screwdriver  
Procedure  
Follow all guidelines to eliminate static electricity while handling the module and other electronic  
devices. Refer to the front of this manual for some suggestions.  
Step 1. If a blank panel is covering the target slot, remove it by unfastening the two screws with  
a 6-inch Phillips screwdriver.  
Figure 6 -- Remove the required blank panels  
To comply with FCC regulations and to optimize air flow, a cover panel or a module must cover  
every chassis slot. No chassis slot should remain open when the unit is operational to limit  
external signal radiation. Securing modules and panels with appropriate screws is also  
important for grounding and compliance.

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.  
P/N 1259003-001 Rev C3

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.

4.4 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.

Figure 22 -- EM316LNXNM-OT general commands for 2SFP module  
Some of these commands apply to both slot-level and port-level contexts as described in the  
navigation portion of this section. Refer to EM316LNXNM-OT documentation for a more complete  
discussion of the Linux-based interface and available commands.

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.

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)#  
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.
