General Information

CHAPTER 1: GENERAL INFORMATION

INTRODUCTION

The iMcV-Giga-FiberLinX-III allows network operators to deploy managed
Ethernet services with a full range of remote management, traffic monitoring,
and alarm reporting features. The single wide module offers two fixed
10/100/1000Mbps copper ports and one fiber port in a fixed transceiver in a
variety of wavelengths for SMMM and CWDM. Another model offers an SFP port
that allows copper or fiber SFPs.

iMcV-Giga-FiberLinX-III

The iMcV-Giga-FiberLinX-III supports three main configuration modes:
Standalone, Host/Remote, or as a Host or a Remote. When using Host/Remote,
the Remote modules can be fully managed without an IP address over the fiber
optic segment. The network operator can choose to assign an IP address to the
Host or Standalone module in any mode. Or, if using a local iMediaChassis
managed chassis, all local and remotely connected iMcV-Giga-FiberLinX-III
modules can be managed using the single IP address of the chassis. This not
only preserves IP addresses and reduces configuration complexity, but
management traffic traveling on the non-IP based transmission channel is kept
isolated from customer traffic, enhancing network security.

The iMcV-Giga-FiberLinX-III offers the following features:

 Securely separates the SNMP management network from the data

network

 IEEE 802.1Q VLAN Tagging
 Q-in-Q VLAN Extra-Tagging with EtherType (TPID) selection
 Remote traffic monitoring

General Information

 Remote automatic alarms
 Bandwidth limiting
 Link Fault Pass Through (LFPT)
 Loopback testing
 Auto Negotiation
 Selective Advertising
 IEEE-802.3ah OAM support
 Management through UMA
 Console

The iMcV-Giga-FiberLinX-III module is a single-slot, chassis-mounted module.
Compatible chassis include the following:

 iMediaChassis series
 MediaChassis series
 IE-MediaChassis series

PORT INTER FACES

Every iMcV-Giga-FiberLinX-III includes the following ports:

 A 10/100/1000 twisted pair (RJ-45) port (EXT MGMT) for

management

One of the following ports:

 One fixed 1000 Mbps Fiber port, OR
 A SFP port capable of receiving a gigabit or 100Mbps fiber optic SFP

module, or a gigabit twisted pair (RJ-45) SFP module

DATA port:

 A 10/100/1000 twisted pair (RJ-45) port

MANAGEMENT

Although the iMcV-Giga-FiberLinX-III provides a twisted pair port solely for
management (EXT MGMT), the iMcV-Giga-FiberLinX-III can be configured to
accept IP-based management traffic from any of its three ports. Enable

management on more than one port, or disable management on all of the ports,
as desired. These switches limit only IP-based management. Host-to-Remote
management is IP-less and is never blocked from the fiber port. Serial port
management of the unit is available via the console port located at the top of the
module using a Mini-jack adapter.

In addition to defining which ports are used to manage the iMcV-Giga-FiberLinX­III units, the management DIP switch settings also define what ports the flow of

the Network Provider’s Management Domain traffic can take through the unit.

See Application Examples for information regarding the Management Domain.

DIP Switch 1 = ON for management on the EXT MGMT port.
DIP Switch 2 = ON for management on the DATA port.
DIP Switch 3 = ON for management on the OPTICS or UPLINK port.

Installation Instructions

CHAPTER 2: INSTALLATION INSTRUCTIONS

Each iMcV-Giga-FiberLinX-III module requires one slot in an iMediaChassis,
MediaChassis or IE-MediaChassis. To install the module in a chassis, remove the
blank faceplates covering the slots where the module is to be installed. Then
slide the module into the chassis card guides until the module is seated securely
in the connector. Secure the module to the chassis by tightening the captive
screw.

The iMcV-Giga-FiberLinX-III module includes on-board SNMP logic. A chassis
other than an iMediaChassis series cannot manage an iMcV-Giga-FiberLinX-III,
so the iMcV-Giga-FiberLinX-III must be managed independently.

When installed in an iMediaChassis, the iMcV-Giga-FiberLinX-III module can be
managed from the chassis by using the Unified Management Agent (UMA). iMcV­Giga-FiberLinX-III modules not managed by UMA must have an IP address
assigned to them after installation before they can be managed. Refer to
Assigning IP Information for more information.

DIP SWITCH SELECTABL E MODE CONFIGURATION

Before installing the module in a chassis, there are two features that must be
selected using the DIP switches. These selections are:

 Enable or disable management on each port

(DIP switches 1, 2, and 3)

 Configure the module as a standalone, a host, or a remote

(DIP switches 7 and 8)

DIP SWITCH SETTINGS

Before installing the iMcV-Giga-FiberLinX-III, use the DIP switches to set the
hardware-configurable features. The DIP switches are located on Bay SW1 on
the iMcV-Giga-FiberLinX-III card. Refer to the diagram and table for switch
settings and available features.

HOST /REMOTE AND STAN DALONE UNITS

The iMcV-Giga-FiberLinX-III can be used as a Host, Remote, or Standalone unit.
Refer to the Application Examples section for examples.

When two iMcV-Giga-FiberLinX-III units are used as a pair, configure one as a
Host unit (DIP Switch 8 = ON) and the other as a Remote unit (DIP Switch 7 =
ON). As a host unit, the iMcV-Giga-FiberLinX-III requests management
information from the attached remote unit. It then displays that information,
along with its own, when queried by SNMP. As a Remote unit, the iMcV-Giga­FiberLinX-III will respond to requests for management information from an
attached Host unit.

The iMcV-Giga-FiberLinX-III default configuration is as a Standalone unit (DIP
Switches 7 and 8 = OFF).

LOSPD

When LoSPD is set to ON, it will force the SFP mode to run at 100Mbps. If it is
set to OFF, the SFP will run at the highest usable speed determined by the SFP
itself.

MINI -SERIAL PORT

A console port, located on the front faceplate of the module, allows the customer
to use a local RS-232 serial interface for management. A special mini-jack to
DB9-F cable is provided with the product for direct connection to a PC serial port.

5

Configuration

CHAPTER 3: CONFIGURATION

SOFTWARE CONFIGURATI ON

The following sections describe the features that can be configured.

ASSIGNING IP INFORMATION

When the iMcV-Giga-FiberLinX-III is installed in an iMediaChassis, use UMA to
manage the iMcV-Giga-FiberLinX-III without an IP address (refer to the iView²
online help for more information on UMA). When the iMcV-Giga-FiberLinX-III is
not installed in an iMediaChassis, SNMP-management is not accessible until the
iMcV-Giga-FiberLinX-III IP information (e.g., IP address, subnet mask, etc.) is
configured (using iConfig, a serial port craft connection, or DHCP). After
assigning iMcV-Giga-FiberLinX-III an IP address, use iView² or another SNMP­compatible Network Management System (NMS) to remotely configure, monitor
and manage the iMcV-Giga-FiberLinX-III.

UN I F I ED MANAGEMENT AGENT (UMA)

Centralized management makes practical sense for networks of all sizes,
especially service provider networks that must monitor and upgrade large
quantities of devices. The Unified Management Agent (UMA) allows operators to
manage all devices installed in a B&B iMediaChassis with a single IP address from
a central location. In addition, UMA allows users to centrally manage and
administer firmware upgrades over multiple devices.

AUT O NEGOTIATION, DUPLEX MODE AND SPEE D

The DATA and EXT MGMT ports on the iMcV-Giga-FiberLinX-III module Auto
Negotiate for speed and duplex. This module also provides the option of
selectively advertising or forcing the speed and duplex.

The iMcV-Giga-FiberLinX-III ships from the factory with Auto Negotiation enabled
on the twisted-pair ports. In this mode, the ports negotiate for speed and
duplex.

6

Configuration

FOR CING THE SPEED AND DUPLEX MODE

Manually set the twisted-pair ports on the iMcV-Giga-FiberLinX-III for 10 Mbps or
100, or 1000 Mbps operation at Half- or Full-Duplex (i.e., 10 Mbps Full-Duplex,
10 Mbps Half-Duplex, 100 Mbps Full-Duplex, 100 Mbps Half-Duplex, 1000 Mbps
Full-Duplex, 1000 Mbps Half-Duplex). The Optics Port operates at 1000Mbps
Full-Duplex for fixed fiber transceivers, and can support 100Mbps as well as
gigabit fiber SFPs.

SELECTIVE ADVERTISIN G

Selective Advertising, when used in combination with Auto Negotiation,
advertises only the configured speed and duplex mode for the twisted pair port.
If a specific speed and/or duplex are desired, B&B Electronics recommends using
Selective Advertising, rather than Force Mode, when connecting to devices that
only use Auto Negotiation.

BAND W I DTH CONTROL

The iMcV-Giga-FiberLinX-III includes bi-directional bandwidth control
(configurable via iView2). This allows the bandwidth limit to be set independently
from the DATA Port to the OPTICS (or UPLINK) Port and vice versa in a single
iMcV-Giga-FiberLinX-III application. In a Host/Remote iMcV-Giga-FiberLinX-III
application, it can be set from the Host unit to the Remote unit and vice versa
(i.e., the bandwidth on the DATA ports on both the Host and Remote modules
can be limited independently).

LINK FAULT PASS THROUGH (LFPT)

Link Fault Pass Through (LFPT) is a diagnostic feature that can be enabled or
disabled. When enabled, it allows the end-user to visually detect that the Link
and the LNK LEDS will extinguish on the front faceplate of the module, when a
fault occurs. LFPT can be enabled through the SNMP software (iView²) or
serial/Telnet.

The iMcV-Giga-FiberLinX-III has three ports: Data, Optics and Ext Management.
LFPT can be enabled between any two ports. For example, if LFPT is configured

as “from” the Optics port “to” the Data port, when a fault occurs on the Optics

port, both LEDs for those ports will extinguish. The end-user can decide which

7

Configuration

port he wants the fault to be reported to, based on which port he wants to be in
control. LFPT allows the fault to be reported down the line, through to the link
partner at the end, such as a switch or a router.

LFPT can be used in addition to setting up SNMP Traps for link up/link down.
LFPT provides a visual way to determine that link is down, and an SNMP Trap
provides a notification of a link down to a designated workstation.

LOO PBACK TESTING

The iMcV-Giga-FiberLinX-III includes Loopback testing functionality. During
loopback testing, management traffic entering the uplink port is still capable of
managing the device. This is selectable form the UNIT screen in a serial/Telnet
session or through iView².

The menu of choices in the CLI includes:

 No loopback, normal traffic mode

 Loopback Enabled

 Loopback, Source/Destination address swap

 Loopback, address swap and clear Multicast bit

 No learning on fiber or Data ports

The menu of choices in iView² includes:

 OFF

 ON

 On- Address Swap

 On-Address swap + Clear MC

8

Configuration

LOOPBACK TESTING ON REMOTE OR STANDALONE

NO LOOPBACK, NORMAL TRAFFIC MODE

The standard mode in which the units function, either as standalone or
Host/Remote.

LOOPBACK ENABLED

Loopback mode without address swap

LOOPBACK, SOURCE/DES TINATION ADDRESS SWAP

A Layer 2 Ethernet switch will discard all received packets with the same MAC
address as sent packets. To avoid this issue the Loopback feature can swap the
source and destination MAC addresses on the looped data. (This selection can
cause a frame with a multicast source address to be created, which violates the
IEEE standard.)

LOOPBACK, ADDRESS SWAP AND CLEAR MULTICAST
BIT

In addition to swapping the source and destination MAC addresses on the looped
data, the Loopback feature can also be set to clear the multicast bit. This allows
the looped data to avoid being blocked by any multicast settings.

LOOPBACK TESTING IN A HOST/REMOTE
CONFIGURATION

The iMcV-Giga-FiberLinX-III is strictly a CPE device; configuration on a Host
would require an iMcV-Giga-FiberLinX-III; select No Learning on OPTICS and
DATA Ports on the Host; on the Remote, choose SRC/DST Address Swap or
Address Swap and Clear Multicast Bit.

9

Configuration

HOST: NO LEARNING ON OPTICS AND DATA PORTS

The Loopback feature can be set to disable address learning on the OPTICS (or
UPLINK) and DATA ports, allowing the loopback to be performed without
interference from MAC address filtering functions. This is a function on the HOST
unit. Set the REMOTE unit for Loopback then set the HOST to disable learning so
Loopback frames pass from the OPTICS port to the DATA port.

REMOTE: SOURCE/DESTINATION ADDRESS SWAP

A Layer 2 Ethernet switch will discard all received packets with the same MAC
address as sent packets. To avoid this issue the Loopback feature can swap the
source and destination MAC addresses on the looped data.

OR

ADDRESS SWAP AND CLEAR MULTICAST BIT

In addition to swapping the source and destination MAC addresses on the looped
data, the Loopback feature can also be set to clear the multicast bit. This allows
the looped data to avoid being blocked by any multicast settings.

CONFIGURATION OPTIONS

for changes to take effect. The Current Values can only be saved and acted on
after the iMcV-Giga-FiberLinX-III has been successfully rebooted.

PASSWORD PROTECTION FOR SERIAL PORT
CONNECTIONS

Password/username is not offered for the serial port by default. This allows the
end user to quickly access the device for some basic configuration capability.
Password protection is provided for the serial configuration process by pressing P
on the main configuration screen. Enter a password, keeping in mind that
passwords are case-sensitive and must not exceed eight characters or include
spaces, and press Enter. This password will be requested whenever logging on.
To remove password protection, select P and, instead of entering a password,
press Enter.

Passwords have the following requirements:

 The password must be between 1 and 8 characters long

 The password consists of a combination of any ASCII characters

except spaces

 Passwords are case sensitive

Passwords are a way to make the management of the devices secure, but
these password lists must be stored and maintained.

DHCP DISABLE (STATIC IP ADDRESSING)

DHCP is disabled in the default configuration. Initially, modules are assigned a Static
default IP Address of 10.10.10.10. Changes to the Static IP Address can be added
manually through iView2 (iConfig view), an RS-232 serial session, or a Console session.
The changes will be initiated following reboot of the module.

DHCP ENABLE (DYNAMIC IP ADDRESSING)

If a DHCP server is present on the network and DHCP is enabled, the DHCP client will
initiate a dialogue with the server during the boot up sequence. The server will then issue
an IP address to the management card. Once the new IP address is received, the SNMP
Management Module will reboot so that the new IP address will take effect. Refer to
About Serial Port Configuration for more information about Enabling/Disabling DHCP.

When there is no DHCP server on the network, use the serial configuration to manually set
the IP addresses.

When DHCP is enabled, the IP address (default 10.10.10.10 or a previously used IP
address, or user-configured) is saved. When DHCP is disabled, the saved IP address will
be reinstated and the device will reboot.

DHCP servers give out lease times: devices renew their leases based on the
administrator-specified time. If a device cannot renew its lease, and the lease expires,
the device will be given the IP address 10.10.10.10 or the previously saved IP and will
reboot.

ACCOUNTS

The following are the three levels for CLI or Telnet account access:

OPERATIONAL MODE CONFIGURATION

There are three modes of operation that can be configured through the Serial/Telnet
session: Mode 1, which supports a mixture of tagged and untagged traffic, Mode 2, Extra
tagging and Mode 3, VLAN Filter.

OPERATION MODE 1 – MIXED TAGGED AND
UNTAGGED FRAMES

In this mode, all tagged and untagged frames pass on any given port. Management to
the device can be tagged or untagged.

19

Configuration

Press the down arrow on the computer keyboard to access additional configuration
selections.

OPERATION MODE 2 PORT BASED XTRA TAGG ING

Any port can be configured for extra tags on the frames.

20

Configuration

Press the down arrow on the computer keyboard to access the additional configuration
commands.

21

Configuration

By default, the device is set up to access ports. However, one must be
configured to be a trunk port.

The Optics port and the Data port can be configured as an access port or a trunk
port. When configuring as a trunk port, an Ethertype can be user-defined (a
trunk port is also defined as a provider port, based on 802.1ad). If an Ethertype
value come in a trunk port and is different than the user-defined Ethertype, it

22

Configuration

will be treated as an unrecognized VLAN tagged frame. If configuring the port as
an access port, enter a VLAN ID between 1 and 4094.

OPERATION MODE 3 VLAN FILTER

In Operation Mode 3, VLAN filters can be configured to allow passing traffic with
up to 64 separate VLAN IDs between the Optics port and the Data port. Choose
whether you want to enter a tag or no tag for management traffic. Enter up to
64 VLAN IDs in the DATA VLANs filed; VLAN IDs may be between 1 and 4094. (If

entering the value of “0”, it will disable that entry. The value of “0” is a default

setting.)

23

Configuration

Note: It is highly recommended that customers configure
the modules to segregate management traffic from data
traffic. This is accomplished by assigning VLAN IDs. If the
traffic is not segregated, then any tests performed may
not get the expected result. By segregating the types of
traffic, the management network is secured from the
customer’s network.

BANDWIDTH (BW)

Displays settings for Bandwidth configuration.

24

Configuration

Ingress Bandwidth
Limit

(CIR)

Monitors the traffic entering the unit (ingress),
discarding traffic that exceeds a fixed Committed
Information Rate (CIR) plus Burst Allocation (BA).
Frames are not held in queue, they either meet the
bandwidth limits and are accepted into the unit or
they are dropped.

Max Burst Allocation
size (BA)

The BA size is specified in bits; the # of bits above
the bandwidth limit before packets are thrown
away.

Ingress Burst
Allocation

Bandwidth limiting can be set at Ingress of each
port individually by setting the MAX Bandwidth
Limit in bits/sec. and the BA in bits. Traffic in
excess of the bandwidth limit plus BA for any time
interval will be dropped. This function utilizes an
advanced “Leaky Token-Bucket” algorithm to
provide typical resolution under 5% of the set
values at all data rate and frames sizes.

Egress Traffic
Shaping

Egress Traffic shaping actively controls the
transmitter and hard limits the maximum frame
rate that can be sent. Frames can be delayed in
the internal buffers of the unit, waiting their turn to

OPTICS PORT

be sent. If the internal buffers are full, excess
traffic will be dropped. The Unit Rate Control can
be used to alleviate this.

Unit Rate Control
Enable/Disable

Allows the end user to globally configure all
Bandwidth settings when enabling Unit Rate Control
(Flow Control). If the END device connected to the
port also has Flow Control enabled, this will ensure
packets will not be dropped.

OSI Notes: The Bandwidth Limit functions can be
adjusted to only count the Layer 1, 2, or 3 portions of the
physical line rate. Layer 1 is used to relate Bandwidth to
the physical line rate where a 100BaseT Ethernet line can
carry a MAX bandwidth of 100Mbps. Layer 2 may be more
useful when the Ethernet Frame may be carried over
several different physical protocols such as SONET or SDH.
Only the bandwidth required by the Ethernet frame is
counted, making this a more consistent number over
different protocols. Layer 3 counting could be used when
a relationship to the actual customer data or line payload
is required. If a 10 Mbps customer file needs to be sent in
one second, then a minimum bandwidth limit of 10Mbps
would need to use Layer 3 counting to allow this.

It must be noted that only Layer 1 counting is not affected
by the size of the Ethernet frame. At 64 byte Ethernet
frames, the MAX bandwidth the line can support at Layer 2
is only 76.2% of the line rate. This maximum falls to

54.8% of the line rate when counting is further limited by
only counting Layer 3 payload data.

port if a fault occurs on another port.

Unit
FlowCtrl

This is the selection for enabling/disabling global flow control.
Once this is set to enabled, you can select the flow control
settings for each port as listed in the above list.

LINK FAULT PASS THROUGH (LFPT)

Link Fault Pass Through (LFPT) is a diagnostic feature that can be enabled or
disabled. When enabled, it allows the end user to visually detect that the Link
and its associated LEDS on the front faceplate of the module are not lit when a
fault occurs. LFPT can be enabled through the SNMP software (iView²) or
serial/Telnet.

The iMcV-Giga-FiberLinX-III has three ports: Data, Optics and EXT management.
LFPT can be enabled between any two ports. For example, if LFPT is configured
as “from” the Optics port “to” the Data port, then when a fault occurs on the
Optics port , both LEDs for those ports will extinguish. The end-user can decide
which port he wants the fault to be reported to, based on which port he wants to
be in control. LFPT allows the fault to be reported down the line through to the
link partner at the end, such as a switch or a router.

33

Configuration

LFPT can be used in addition to setting up SNMP Traps for link up/link down.
LFPT provides a visual way to determine that link is down, and an SNMP Trap
provides a notification of a link down to a designated workstation.

CONFIGURATION FILE SAVE / RESTORE FUNCTION

REQUIREMENTS

The Configuration File Save/Restore Function allows a user the ability to backup
all the configuration settings of a unit. With this backup, a user can restore
settings to a unit if necessary or use this backup to apply the same settings to a
different unit.

All configurable managed objects are saved in a configuration file that is stored
in the unit’s Large File Area. This includes all configurable settings such as VLAN
configurations, IP Address configuration and SNMP agent settings. The
configuration file can be transferred from the unit to a PC and saved to disk
through the iView2 (iConfig view) utility. The configuration file can be transferred
from a PC to a unit of the same type through iView2 (iConfig view) or TFTP into

the unit’s Large File Area. After the transfer is complete, the unit copies the

configuration to flash and reboots.

The configuration file’s contents is device-type specific and can be identified by
iView2 (iConfig view) as a configuration file as well as to what type of device it is
applicable to.

Operation

CHAPTER 4: OPERATION

Before using iMcV-Giga-FiberLinX-III, decide the following:

 Will iMcV-Giga-FiberLinX-III units be located at only one or at both

ends of the fiber?

 How will the iMcV-Giga-FiberLinX-III units be managed?

 Will VLAN IDs be defined?

HOW MANY iMcV-GIGA-FIBERLINX-III UNITS WILL BE
USED?

 Two for Host/Remote applications–allows IP-less management

providing greater security

 One for a single unit application

 One unit as a host and a Giga-AccessEtherLinX-II or IE-MultiWay as

a Remote

HOW WILL THE iMcV-GIGA-FIBERLINX-III BE MANAGED?

The iMcV-Giga-FiberLinX-III can be managed through any of its three ports (and
any combination thereof) or from the chassis. Using the EXT MGMT/OPTICS (or
UPLINK) port combination separates management traffic from the data and
provides the highest level of security. UMA management does not require an IP
address.

WILL VLAN IDS BE DEFINED?

When VLAN traffic is used with specific tags on the DATA port, it is necessary to
define VLAN IDs (refer to VLAN Operation Modes section). VLANs may be
tagged, untagged, or double-tagged.

38

Operation

SMALL FORM-FACTOR PLUGGABLE POR TS (SFP)

iMcV-Giga-FiberLinX-III modules are available with one optional SFP port. The
SFP port can support a 100Mbps or 1000Mbps fiber SFP. It can also support a
1000Mbps or 10/100/1000Mbps copper SFP. SFPs must be MSA-compliant, with
or without Digital Diagnostics Monitoring Interface (DDMI). The SFP port will
accept third-party SFPs. DDMI statistics provide real-time access to transceiver
operating parameters such as voltage, temperature, laser bias current, and both
transmitted and received optical power. DDMI information can be accessed in
iView2 by clicking Tables > SFP Info.

Note: iMcV-Giga-FiberLinX-III has been tested
with the B&B Electronics SFP modules. You can
install any MSA-compliant SFP module. However,
B&B Electronics does not guarantee the
functionality of non- B&B Electronics SFP modules
due to possible non-conformity with MSA design
standards.

Troubleshooting

CHAPTE R 6: TROUBLESHOOTING

 If two iMcV-Giga-FiberLinX-III Host/Remote units are not communicating

properly, make sure one is a Host and the other is a Remote. If the second unit
is not configured as a Remote, it will be recognized as a Standalone unit and the
Host and Remote units will not communicate with each other properly. Setting
the OPTICS port management DIP Switch 3 to the ON position on both modules
will allow performing a simple PING test. This is possible only if PINGing from
the computer through the optics uplink port, which is highly unusual. The EXT or
data switch must be enabled and connected to the computer to ping either
device.

 If a link on a twisted pair port cannot be established, make sure the cable is in

working order; if not, replace the cable (iMcV-Giga-FiberLinX-III includes Auto­Cross; a link should be detected regardless of the CAT5 cable type).

 If a fiber link cannot be established, make sure that the fiber transceivers on

iMcV-Giga-FiberLinX-III are not over/under driving the fiber receivers. Make
sure the fiber mode and wavelength on both iMcV-Giga-FiberLinX-III units match
(i.e., both are 1310 nm single-mode fiber).

 Make sure the port speeds on iMcV-Giga-FiberLinX-III match those on the end

devices connected to iMcV-Giga-FiberLinX-III. B&B Electronics recommends
configuring all connected devices to Auto Negotiation, or if using Force mode,
ensure speed and duplex settings match.

 If using single-strand fiber, make sure the pair of devices is compatible single-

strand fiber devices. For example, an iMcV-Giga-FiberLinX-III TX/SSFX-SM1310­SC which transmits 1310 nm and receives 1550 nm must be connected to a
device which transmits 1550 nm and receives 1310 nm.

 If using an iMcV-Giga-FiberLinX-III unit with an SFP port and it is not functioning

properly or at all, make sure that the installed SFP module is the correct speed
(1000 Mbps).

 If management is not functioning properly, make sure that the DIP Switch

settings are accurate for the port to be managed.

 To restore the unit to factory default settings, use the cleandb function via the

serial port (refer to the Device-Specific Options from the Command Line section
for more information). This is especially helpful if the module may have been
configured improperly. If restarting to factory defaults is necessary, B&B

42

Troubleshooting

Electronics recommends using this function on both units in Host/Remote
applications, then reconfiguring all settings.

 Ensure READ/WRITE Community Strings for iMcV-Giga-FiberLinX-III and iView²

are the same.

 Ensure none of the twisted-pair ports on the iMcV-Giga-FiberLinX-III are

connected to the twisted-pair port on the Management Module in an
iMediaChassis series chassis.

Fiber Optic Cleaning Guidelines

CHAPTER 7: FIBER OPTIC C LEANING GUIDELINES

Fiber Optic transmitters and receivers are extremely susceptible to
contamination by particles of dirt or dust, which can obstruct the optic path and
cause performance degradation. Good system performance requires clean optics
and connector ferrules.

1. Use fiber patch cords (or connectors, if you terminate your own

fiber) only from a reputable supplier; low-quality components can
cause many hard-to-diagnose problems in an installation.

2. Dust caps are installed by the manufacturer to ensure factory-clean

optical devices. These protective caps should not be removed until
the moment of connecting the fiber cable to the device. Should it
be necessary to disconnect the fiber device, reinstall the protective
dust caps.

3. Store spare caps in a dust-free environment such as a sealed

plastic bag or box so that when reinstalled they do not introduce
any contamination to the optics.

4. If you suspect that the optics have been contaminated, alternate

between blasting with clean, dry, compressed air and flushing with
methanol to remove particles of dirt.

Appendix C: Troubleshooting

APPENDIX C: TROUBLESHOOTING

If a fiber connection cannot be established, perform the following to make sure
that the fiber transceivers on the iMcV-Giga-FiberLinX-III are not over/under
driving the fiber receivers:

1. Make sure the fiber wavelength on both connected devices match

(i.e. both are 1310 nm single-mode fiber).

2. Make sure the twisted-pair port speed on the iMcV-Giga-FiberLinX-

III matches that of the end devices connected to the iMcV-Giga­FiberLinX-III. Configure the iMcV-Giga-FiberLinX-III and its link
partner to Auto Negotiation or, if using Force mode, be sure speed
and duplex match.

3. iMcV-Giga-FiberLinX-III allows the end user to assign a VLAN tag to

all management traffic (SNMP and telnet). It is important to
understand that IF using telnet or iView2 to assign a VLAN tag to
management traffic then as soon as this setting is saved the
connectivity will be lost until the PC becomes a member of the
VLAN which was assigned to management traffic.

4. If a VLAN tag has been assigned to management traffic and the end

user cannot re-establish a connection to the device via iView2 or
telnet, directly connect a PC to the device via the serial cable and
review/modify the changes made (reference section on serial port
config).

64

Appendix D: Unified Management Agent (UMA)

APPENDIX D: UNIFIED MANAGEMENT AGENT
(UMA)

UMA operates in conjunction with B&B Electronics devices with on-board
intelligence (e.g., the iMcV-Giga-FiberLinX-III and the iMediaChassis series. For
example, install 20 devices in the chassis at the Central Office (CO), then
connect each to a remote iMcV-Giga-FiberLinX-III unit installed at the customer's
premise (CPL); UMA will then allow users to manage all 40 devices (including the
chassis at the CO) via a single IP address. Users may still assign IP addresses to
each iMcV-Giga-FiberLinX-III and manage them independently when the SNMP
Management Card within the iMediaChassis is omitted.

WITH THE UNIFIED MANAGEMENT AGENT

When an SNMP request for a iMcV-Giga-FiberLinX-III comes in, the SNMP
Management Card in the iMediaChassis passes the request to the SNMP agent in
the specific module. The SNMP agent in the iMcV-Giga-FiberLinX-III provides the
relevant management information which is then routed via the SNPM
Management Card and supplied to the client GUI (iView2).

WITHOUT THE UNIFIED MANAGEMENT AGENT

When an SNMP request for an iMcV-Giga-FiberLinX-III comes in, the
iMediaChassis cycles through each slot checking for iMcV-Giga-FiberLinX-III
modules. The iMediaChassis sees the first iMcV-Giga-FiberLinX-III modules in
the chassis, and they can be selected, but they cannot be managed; the full
management interface is inaccessible. Management for each iMcV-Giga­FiberLinX-III requires a separate connection and a separate IP address.

EASY UPGRADES WITH T HE UNIFIED MANAGEMENT
AGENT

 Upgrade one or multiple Host (CO) or Remote (CPE) devices with

just a few mouse clicks

 All devices in chassis are fully functional while upgrades are in

process

65

Appendix D: Unified Management Agent (UMA)

 Manage up to 41 devices with a single IP address

 Telnet capability available for all devices

 Conserve usage of switch ports; separate SNMP connections for

installed devices are not required
