About the iMcV-Giga-FiberLinX-II
NOTE
Unless noted otherwise, all references to the iMcV-Giga-FiberLinX-II in this manual are also
applicable to the iMcV-Giga-FiberLinX-II TX/SFP and iMcV-Giga-FiberLinX-II SFP/SFP.
Overview
The iMcV-Giga-FiberLinX-II allows network operators to deploy managed Ethernet
services, with a full range of remote management, traffic monitoring, and alarm
reporting features. Operators can choose from enhanced versions combining 1000
Mbps fiber to 10/100/1000 Mbps copper, or an all-copper version. The fiber-tocopper versions are available for a range of fiber connectors (SC, ST, or SFP) and a
variety of wavelengths, supporting higher density CWDM and single-strand fiber
operation.
The iMcV-Giga-FiberLinX-II supports two main configuration modes: Standalone or
Host/Remote. When using Host/Remote, the Remote modules can be fully managed
without an IP address using a secure management channel. In either mode, the
network operator can choose to assign an IP address to the Host or Standalone
module. Or, if using a local iMediaChassis managed chassis, all local and remotely
connected iMcV-Giga-FiberLinX-II 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-II 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
•
•
Remote automatic alarms
•
Bandwidth limiting
FiberAlert (loss return)—Fiber versions only
•
•
FX and TX LinkLoss (Link Fault Pass Through (LFPT)
Loopback testing
•
Auto Negotiation
•
•
Selective Advertising
AutoCross
•
Broadcast Storm Protection
•
Provisioned for IEEE-802.3ah OAM support
•
•
Coming soon: ability to be configured as a Remote device and managed through
UMA

The iMcV-Giga-FiberLinX-II module is a double-slot, chassis-mounted module.
Compatible chassis include the following:
• iMediaChassis series
• MediaChassis series
• IE-MediaChassis series
Port Interfaces
Every
iMcV-Giga-FiberLinX-II
includes the following port:
• A 10/100/1000 twisted pair port (EXT MGMT) for management
One of the following uplink ports:
• One fixed 1000 Mbps Fiber port
• A SFP port capable of receiving a gigabit fiber optic SFP module or a
gigabit twisted pair (RJ-45) SFP module
And one of the following DATA ports:
• A 10/100/1000 twisted pair (RJ-45) port
• A SFP port capable of receiving a gigabit fiber optic SFP module or a gigabit
twisted pair (RJ-45) SFP module
Configure the iMcV-Giga-FiberLinX-II by using either the serial craft port connection,
through SNMP management application such as iView² or a Telnet session.
About Serial Port Configuration
The iMcV-Giga-FiberLinX-II includes a serial port on the unused pins of the EXT
MGMT Ethernet port. This RS-232 serial connection provides access to the iMcVGiga-FiberLinX-II module configuration screens. These configuration screens are also
accessible from a Telnet connection.
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 iConfig, an RS-232 Serial session, or Telnet. 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
2
Page 6
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 iConfig or serial configuration to
manually set the IP addresses.
When DHCP is enabled, the IP address (default 10.10.10.10 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 and will reboot.

iView
is available in several versions and can also function as a snap-in module for
HP OpenView Network Node Manager. For assistance in selecting the right version
of iView² for a specific operating system, please visit:
http://www.imcnetworks.com/products/iview2.cfm
2
iView
supports the following platforms:
• Windows NT
•
Windows 2000
Windows XP
•
•
Windows Vista
In addition, there are Java versions of iView² for other Java capable operating systems
such as Linux.
iConfig Utility
iConfig is a configuration utility in iView² that allows the user to quickly and easily
complete the initial SNMP configuration for IMC Networks’ SNMP-manageable
devices. iConfig can set the IP address, set the Subnet Mask and Default Gateway,
define the Community Strings, and define SNMP Traps. iConfig can also be used to
upload new versions of unit software.
iConfig offers an authorized IP address system and access restriction to MIB groups
supported by the IMC Networks manageable devices. These extra layers of security
are purely optional and do not effect SNMP compatibility in any way.
Default Username/Password
The default user ID and password for both iConfig and Telnet are the following:
User: admin

Installation
Each iMcV-Giga-FiberLinX-II module requires two slots 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-II module includes on-board SNMP logic. A chassis other
than an iMediaChassis series cannot manage an iMcV-Giga-FiberLinX-II, so the iMcVGiga-FiberLinX-II must be managed independently.
When installed in an iMediaChassis, the iMcV-Giga-FiberLinX-II module can be
managed from the chassis by using the Unified Management Agent (UMA). Refer to
http://www.imcnetworks.com/Products/Unified_Management_Agent.cfm
for more
information on using UMA with iConfig, iMediaChassis and iMcV-Giga-FiberLinX-II.
iMcV-Giga-FiberLinX-II modules not managed by UMA must have an IP address
assigned to them after installation before they can be managed. Refer to
Information
for more information.
Assigning IP
Small Form-Factor Pluggable Ports (SFP)
iMcV-Giga-FiberLinX-II modules are available with one or two optional SFP port(s). It
is necessary to use a 1000 Mbps speed SFP for fiber connections or any gigabit
copper SFP (1000 Mbps or 10/100/1000 Mbps). In addition, many SFPs, including
those from IMC Networks, feature enhanced diagnostics capabilities with a Digital
Diagnostics Monitoring Interface (DDMI). 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
2
iView
iMcV-Giga-FiberLinX-II has been tested with the IMC Networks SFP modules. You can install
any MSA-compliant SFP module. However, IMC Networks does not guarantee the
functionality of non-IMC Networks SFP modules due to possible non-conformity with MSA
design standards.

Hardware 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-II, use the DIP Switches to set the
hardware-configurable features. The DIP Switches are located on switch SW1 on the
iMcV-Giga-FiberLinX-II card. Refer to the diagram and table for switch settings and
available features.

When two iMcV-Giga-FiberLinX-II 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-II requests management information from the
attached remote unit. It then displays that information, along with its own, when
9
Page 13
queried by SNMP. As a Remote unit, the iMcV-Giga-FiberLinX-II will respond to
requests for management information from an attached Host unit.
The iMcV-Giga-FiberLinX-II default configuration is as a Standalone unit (DIP
Switches 7 and 8 = OFF).
Management
Although the iMcV-Giga-FiberLinX-II provides a twisted pair port solely for
management (EXT MGMT), the iMcV-Giga-FiberLinX-II 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
always available on the EXT MGMT port regardless of the DIP Switch settings.
In addition to defining which ports are used to manage the iMcV-Giga-FiberLinX-II
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.
10
Page 14
Software Configuration
The following sections describe the features that can be configured. Refer to the
iView² online help for iMcV-Giga-FiberLinX-II module configuration information.
Assigning IP Information
When the iMcV-Giga-FiberLinX-II is installed in an iMediaChassis, use UMA to
manage the iMcV-Giga-FiberLinX-II without an IP address (refer to the iView² online
help for more information on UMA). When the iMcV-Giga-FiberLinX-II is not
installed in an iMediaChassis, SNMP-management is not accessible until the iMcVGiga-FiberLinX-II IP information (e.g., IP address, subnet mask, etc.) is configured
(using iConfig, a serial port craft connection, or DHCP). After assigning iMcV-GigaFiberLinX-II an IP address, use iView² or another SNMP-compatible Network
Management System (NMS) to remotely configure, monitor and manage the iMcVGiga-FiberLinX-II.
Auto Negotiation, Duplex Mode, and Speed
The DATA and EXT MGMT ports on the iMcV-Giga-FiberLinX-II module Auto
Negotiate for speed and duplex mode. This module also provides the option of
selectively advertising or forcing the speed and duplex mode.
Auto Negotiation
The iMcV-Giga-FiberLinX-II ships from the factory with Auto Negotiation enabled on
the twisted-pair ports. In this mode, the ports negotiate for speed and duplex.
Forcing the Speed and Duplex Mode
Manually set the twisted-pair ports on the iMcV-Giga-FiberLinX-II 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 FullDuplex, 1000 Mbps Half-Duplex). The Optics Port operates at 1000Mbps FullDuplex.
Selective Advertising
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 mode are desired, IMC Networks recommends using Selective
Advertising, rather than Force Mode, when connecting to devices that only use Auto
Negotiation.
11
Page 15
Bandwidth Control
The iMcV-Giga-FiberLinX-II includes bi-directional bandwidth control in 32 Kbps
increments (configurable via iView
2
). 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-II application. In a dual iMcV-Giga-FiberLinX-II
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).
NOTE
Management packets do not have priority over data packets.
12
Page 16
FX/TX LinkLoss and FiberAlert
During normal operation, link integrity pulses are transmitted by all point-to-point
Ethernet devices. When an iMcV-Giga-FiberLinX-II receives valid link pulses, it
knows that the device to which it is connected is up, and that the copper or fiber
cable coming from that device is intact. The appropriate LNK (link) LED is lit to
indicate this. For troubleshooting information utilizing the LinkLoss and FiberAlert
features of the iMcV-Giga-FiberLinX-II modules, refer to
Troubleshooting
at the end of
this manual.
** WARNING **
FiberAlert and LinkLoss features cause data interruptions designed to alert remote sites of line
failures. These data interruptions can be misinterpreted as module failures when these features
are enabled. Enable these features only when the resulting data interruptions and causes are
well understood.
FX LinkLoss
FX LinkLoss is a link integrity monitoring feature that forwards fiber link faults to the
RJ-45 Data port to indicate that a fiber link fault has occurred.
TX LinkLoss
TX LinkLoss is a link integrity monitoring feature that forwards an RJ-45 link fault to
the fiber connected device to indicate that a link fault has occurred.
FiberAlert
FiberAlert minimizes the problems associated with the loss of one strand of fiber.
Normally when a single strand of fiber is lost, the transmitting side of the connection
is unaware that there is a fault. FiberAlert returns faults back on the fiber they came
in on.
Using LinkLoss and FiberAlert
In a typical central site to remote site media conversion, it is recommended that the
enable the LinkLoss and FiberAlert features are enabled as indicated in the following:
FiberAlert and LinkLoss
Feature Enabled Fault Location Port affected
FiberAlert
TX LinkLoss
FX LinkLoss
Remote Side Only Fiber Fiber
Remote Side (or both) Twisted Pair Fiber
Host Side (or both) Fiber Twisted Pair
** WARNING **
Do not enable FiberAlert on both modules when using iMcV-Giga-FiberLinX-II in pairs. This
13
Page 17
will cause them to lock up when a fault occurs on the fiber. Only enable FiberAlert on the
remote module.
Link Fault Pass Through (LFPT)
Link Fault Pass Through is a troubleshooting feature that combines TX and FX
LinkLoss from both the local and remote modules. LFPT is enabled by turning on
both FX and TX LinkLoss on both modules. This feature allows either end of the
conversion to detect a link fault occurring at the other end of the media conversion
chain.
Regardless whether a break occurs on a copper or fiber segment between the End
device and the media converter, or between the two media converters, End devices
at both ends.
Regardless if there is a break in segment 1, 2 or 3, the link will drop on the switches
at both ends.
The link fault is passed through the media conversion and is observed at each end. It
acts just like it would if the devices were directly connected.
NOTE
FiberAlert can also be added to the remote side of the pair to further assist in locating a
fault.
Last Gasp
NOTE
The iMcV-Giga-FiberLinX-II does not support Last Gasp, as the present hardware design
cannot provide that feature.

Loopback Testing
The following functions are available during loopback testing. 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. There are
no LoopBack test options in 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
Loopback Testing on Remote or Standalone
No loopback, normal traffic mode
The standard mode in which the units function, either as stand-alone or
Host/Remote.
Loopback Enabled
Loopback mode without address swap
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. (This selection can cause a frame
with a multicast source address to be created, which violates the IEEE standard.)
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
Configure the Host by selecting No Learning on OPTICS and DATA Ports; on the
Remote, choose SRC/DST Address Swap or Address Swap and Clear Multicast Bit.
15
Page 19
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.
NOTE

Using Telnet
It is necessary to assign the iMcV-Giga-FiberLinX-II an IP address before using a Telnet
session (this is not necessary when using UMA). Refer to the
Assigning IP Information
section for more information. All of the configurations that can be performed from
the serial port can also be performed using a Telnet session; only one Telnet session
can be launched at a time.
The following are the three levels for Telnet account access:
User:
View status, change own password, and reboot.
Operator:
Administrator:
All User privileges mentioned above, plus ability to change settings.
Operator privileges mentioned above, plus ability to add/delete
accounts and reinitialize the unit to default settings (cleandb).
Serial Configuration/Telnet Session
The following sections describe serial configuration (including VLAN configuration),
Telnet session configuration, and DHCP configuration.
NOTE
Some screens may show TX and FX for the port titles where TX = DATA port and FX = OPTICS
(or UPLINK) port. The examples are from firmware version 512-00A2.
Serial Port (EXT MGMT)
NOTE
The serial port (EXT MGMT) is always set to Administrator level. The password for Telnet
sessions is the password that is set and used in iConfig (refer to the iConfig section for more
information).

speeds:
• 10/100/1000 Mbps Half-Duplex
• 10/100/1000 Mbps Full-Duplex
Advertise Ctrl
- This is the Selective Advertising feature. Selective Advertising is used
in combination with Auto Negotiation to advertise the selected speed and duplex
mode for the DATA and EXT MGMT ports. This allows advertising: all speeds and
duplex modes; 10 Mbps Half-Duplex; 10 Mbps Full-Duplex; 100 Mbps Half-Duplex;
100 Mbps Full-Duplex; 10 Mbps Half and Full-Duplex; etc. Auto Negotiation must
be enabled for Selective Advertising to work.
NOTE
If a specific speed and/or duplex mode are desired, IMC Networks recommends using
Selective Advertising, instead of Force Mode, when connecting to devices that can only
Auto Negotiate. For the FO uplink versions, the port is always force flow control 100 FDX
and cannot be changed.
23
Page 27
Advertise FlowC and Force FlowCtrl
—the following are Advertise Control features.
When using Flow Control functionality on any port, enable Flow Control (refer to
Unit Flow Control
for more information). Next, configure each port individually:
• To use Auto Negotiation and Flow Control:
Advertise FlowC = Advertise Flow, Force FlowCtrl = Flow Auto
• To use Auto Negotiation but not Flow Control
Advertise FlowC = No Flow
• To use Flow Control and force the port speed (Port Speed Ctrl)
Advertise FlowC = Advertise Flow, Force FlowCtrl = Frc FlowCt
All RJ-45 ports feature Flow Control in Full-Duplex and Back Pressure Flow control in
Half-Duplex. Back Pressure Flow Control is a hardware based flow control that forces
collisions on the line to limit bandwidth.
Unit FlowControl
- Enable or disable Flow Control functionality on the unit. This
must be enabled to use Flow Control on any port.
Mode Configuration—config

is configured in Default mode or Transparent mode.
Transparent Mode – with either (not both) Data and Optics Mgmt dipswitches
set to on, all traffic passes between Optics and Data port EXCEPT what has
been defined as the Management Domain. The Management Domain can either be
defined as untagged traffic or traffic with a specified VLAN ID.
In Transparent Mode with BOTH Optics and Data Mgmt dipswitches set to off,
all traffic passes between the Optics and Data Ports.

Application Overview
Before using iMcV-Giga-FiberLinX-II, decide the following:
Will iMcV-Giga-FiberLinX-II units be located at only one or at both ends of the
•
fiber?
32
Page 36
• How will the iMcV-Giga-FiberLinX-II units be managed?
•
Will VLAN IDs be defined?
How many iMcV-Giga-FiberLinX-II 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 as a Remote
•
How will the iMcV-Giga-FiberLinX-II be managed?
The iMcV-Giga-FiberLinX-II 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 any/all of the DATA ports, it is
necessary to disable Transparency and define VLAN IDs (refer to
VLAN Configuration
section). When it is desirable to use VLAN tagged, untagged, or double-tagged traffic,
enable Transparency.
Application Examples
The following are application examples of the different VLAN configuration modes
available using the iMcV-Giga-FiberLinX-II. If assistance is required to configure an
application, contact IMC Networks Technical Support at
techsupport@imcnetworks.com
.
The application modes include the following:
Mode One – Default
•
•
Mode Two – Transparency with Untagged Management
Mode Three - Transparency with Tagged Management
•
Mode Four - Transparency with Extra Tagging (Q-in-Q)
•
•
Mode Five - Port VLAN
Mode Six - PortVLAN Filter
•
NOTE
When configuring VLAN IDs, remember to use any VLAN ID between 1 and 4,094. The VLAN
IDs used in the following applications are for example purposes ONLY.
33
Page 37
Mode One-Default
Default mode passes only untagged data between the DATA port and the OPTICS (or
UPLINK) port. This mode is the factory default and is provided as a starting point
from which to configure the iMcV-Giga-FiberLinX-II modules. It is not intended as a
mode for normal use.
NOTE
Default Mode does not provide any management traffic protection and is not
recommended for normal use.
Mode Two-Transparency with Untagged Management
Transparent with Untagged Management mode passes tagged traffic between the
DATA port and the OPTICS (or UPLINK) port and isolates untagged traffic as
management domain traffic (untagged).
To configure this mode, do the following:
Set the management DIP Switch ON for the ports using management (in this
1.
example it is the OPTICS (or UPLINK) port: 3 = ON). To enable External
Management (EXT MGMT), set DIP Switch 1 to ON.
(otherwise, leave DIP Switch
1 in the OFF position (default from factory) to disable EXT MGMT)

Mode Three-Transparency with Tagged Management
Transparent with Tagged Management mode passes both tagged and untagged traffic
between the DATA port and the OPTICS (or UPLINK) port. By using a VLAN Tag, it
is possible to isolate and route the management path in the module. This method
can be used with or without continuing the management path down the EXT MGMT
port.
To configure this mode, do the following:
Set the management DIP Switch ON for the ports using management (in this
1.
example it is the OPTICS (or UPLINK) 3 = ON and EXT MGMT 1 = ON).
Set Transparent Mode to allow both tagged and untagged traffic to pass:

Troubleshooting
• If two iMcV-Giga-FiberLinX-II 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 (or UPLINK) 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-II 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-II are not over/under driving the fiber receivers. For fiber
specifications, please visit www.imcnetworks.com/support/fpblookup.cfm. Make
sure the fiber mode and wavelength on both iMcV-Giga-FiberLinX-II units match
(i.e., both are 1310 nm single-mode fiber).
Make sure the port speeds on iMcV-Giga-FiberLinX-II match those on the end
•
devices connected to iMcV-Giga-FiberLinX-II. IMC Networks 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-II 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-II 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).
When using the FiberAlert feature, make sure that FiberAlert is enabled on only
•
one unit when connecting two iMcV-Giga-FiberLinX-II units, or when connecting
an iMcV-Giga-FiberLinX-II to another IMC Networks media converter which
includes the FiberAlert feature.
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, IMC
Networks recommends using this function on both units in Host/Remote
applications, then reconfiguring all settings.
Ensure READ/WRITE Community Strings for iMcV-Giga-FiberLinX-II and iView²
•
are the same.
Ensure none of the twisted-pair ports on the iMcV-Giga-FiberLinX-II are
•
connected to the twisted-pair port on the iMediaCenter chassis or the
management module in an iMediaChassis series chassis.

Fiber Optic Cleaning 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.
Use fiber patch cords (or connectors, as appropriate) only from a reputable
1.
supplier; low-quality components can cause many hard-to-diagnose problems in
an installation.
Dust caps are installed at IMC Networks to ensure factory-clean optical devices.
2.
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.
Store spare caps in a dust-free environment such as a sealed plastic bag or box
3.
so that when reinstalled they do not introduce any contamination to the optics.
If it is suspected that the optics have been contaminated, alternate between
4.
blasting with clean, dry, compressed air and flushing with methanol to remove
particles of dirt.

Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to any product, add-in modules or
stand alone units containing electronic components. Always observe the following
precautions when installing or handling these kinds of products
Do not remove unit from its protective packaging until ready to install.
1.
Wear an ESD wrist grounding strap before handling any module or component.
2.
If the wrist strap is not available, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.
Hold the units by the edges; do not touch the electronic components or gold
3.
connectors.
After removal, always place the boards on a grounded, static-free surface, ESD
4.
pad or in a proper ESD bag. Do not slide the modules or stand alone units over
any surface.
WARNING!
Integrated circuits and fiber optic components are
extremely susceptible to electrostatic discharge damage. Do not
handle these components directly unless you are a qualified service
technician and use tools and techniques that conform to accepted
industry practices.
