I - About the iMcV-Giga-FiberLinX-II
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. This unit converts 1000 Mbps fiber to 10/100/1000 Mbps copper.
In addition, a range of fiber connectors (SC, ST, or SFP) and a variety of wavelengths,
supporting higher density CWDM and single-strand fiber operation are available.
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 (when the SNMP module
is installed in the same chassis). 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:

iView2 Management Software
iView² is the IMC Networks management software designed specifically for the IMC
Networks “iMcV” family of modules. It features a graphical user interface (GUI) and
gives network managers the ability to monitor and control the manageable IMC
Networks products.
iView2 is available in several versions and can also function as a snap-in module for
HP OpenViewTM Network Node Manager. For assistance in selecting the right version
of iView² for your operating system, please visit:
iView2 supports the following platforms:
Windows™ 98 • 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 lets you quickly and easily complete the
initial SNMP configuration for IMC Networks’ SNMP-manageable devices. With
iConfig you 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
Password–admin
about setting or changing passwords.
NOTE
It is the responsibility of the network administrator to store and maintain the
password lists.

About Dynamic Host Control Protocol (DHCP)
The iMcV-Giga-FiberLinX-II module includes a Dynamic Host Control Protocol
(DHCP) client. By default, the DHCP client is disabled. When a DHCP server is
enabled on the network, the DHCP client will initiate a dialogue with the server
during the boot up sequence. The server will then issue an IP address, Default
Gateway address and Subnet mask to the module. After the new IP address is
received, the iMcV-Giga-FiberLinX-II will reboot with the new IP address.
When a DHCP server is not on the network, ensure that DHCP is disabled and use
iConfig or serial configuration to manually set the IP addresses (refer to the Serial
Configuration/Telnet Session section for DHCP Enable/Disable information).
If an IP address is already assigned to the device, and DHCP is then enabled, that
original IP address is saved. When DHCP is disabled, the saved IP address will be
reinstated and the device will reboot.

III - 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.

Host/Remote and Standalone Units
The iMcV-Giga-FiberLinX-II can be used as a Host, Remote, or Standalone unit.
Refer to the Application Examples section for examples.
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
6
Download from Www.Somanuals.com. All Manuals Search And Download.
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), you can configure iMcV-Giga-FiberLinX-II to accept IP-
based management traffic from any of its three ports. You can enable management
on more than one port, or you can disable management on all of the ports, if 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 Host
unit is always available on the DB-9 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. By
configuring a unique Management Domain, a Host/Remote pair of units can extend a
secure-management LAN to a remote location to manage other equipment at the
remote site.

IV - Installation Instructions
Each iMcV-Giga-FiberLinX-II module requires two slots in an iMediaChassis or
MediaChassis. To install the module in a chassis, remove the blank faceplates
covering the slots where you want to install the module. 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 iMcV-
Giga-FiberLinX-II must be managed independently.
When installed in an iMediaChassis, you can manage the iMcV-Giga-FiberLinX-II
module from the chassis by using the Unified Management Agent (UMA).
more information about using UMA with iConfig, iMediaChassis and iMcV-Giga-
FiberLinX-II.
iMcV-Giga-FiberLinX-II modules not managed by UMA must have an IP address
Small Form-Factor Pluggable Ports (SFP)
iMcV-Giga-FiberLinX-II modules are available with one or two optional SFP port(s).
You must use a 1000 Mbps speed SFP for fiber connections or any gigabit copper SFP
(1000 Mbps or 10/100/100 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
iView2 by clicking Tables
>
SFP Info.
NOTE
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.
V - Software Configuration
The following sections describe the features you can configure. Refer to the iView²
online help for iMcV-Giga-FiberLinX-II module configuration information.
8
Download from Www.Somanuals.com. All Manuals Search And Download.
Assigning IP Information
When the iMcV-Giga-FiberLinX-II is installed in an iMediaChassis, you can use UMA
to manage your 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 iMcV-
Giga-FiberLinX-II IP information (e.g., IP address, subnet mask, etc.) is configured
(using iConfig, a serial port DB-9 connection, or DHCP). After assigning iMcV-Giga-
FiberLinX-II an IP address, you can use iView² or another SNMP-compatible Network
Management System (NMS) to remotely configure, monitor and manage the iMcV-
Giga-FiberLinX-II.
Autonegotiation, Duplex Mode, and Speed
The DATA port (non-SFP version) and EXT MGMT port on the iMcV-Giga-FiberLinX-II
module autonegotiate for speed and duplex mode. This module also provides the
option of selectively advertising or forcing the speed and duplex mode. Refer to Port
AutoCross Feature for Twisted Pair Connection
All twisted pair ports on the iMcV-Giga-FiberLinX-II include AutoCross, a feature that
automatically selects between a crossover workstation and a straight-through
connection depending on the connected device. Refer to Port Configuration on page
19 for more information.
Autonegotiation
The iMcV-Giga-FiberLinX-II ships from the factory with autonegotiation enabled on
the twisted-pair and fiber ports. In this mode, the ports negotiate for speed and
Forcing the Speed and Duplex Mode
You can manually set the twisted-pair ports on the iMcV-Giga-FiberLinX-II for 10
Mbps or 100 Mbps operation at Half- or Full-Duplex (i.e., 10 Mbps FDX, 10 Mbps
HDX, 100 Mbps FDX, etc.). The OPTICS port operates at 1000 FDX. The FX port
for more information.
Selective Advertising
Selective Advertising, when used in combination with autonegotiation, 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

(configurable via iView2). This allows you to
independently set the bandwidth limit 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 you can set it
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.
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 the device to which it is connected is up, and the copper or fiber cable
coming from that device is intact. The appropriate “LNK” (link) LED is lit to indicate
this. For troubleshooting information using the LinkLoss and FiberAlert features of the
iMcV-Giga-FiberLinX-II modules, refer to Troubleshooting at the end of this manual.
** WARNING **
The 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.
10
Download from Www.Somanuals.com. All Manuals Search And Download.
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 you
enable the LinkLoss and FiberAlert features as indicated in the following:
FiberAlert and LinkLoss

Fault Location
Port affected

** WARNING **
Do not enable FiberAlert on both modules when using iMcV-Giga-FiberLinX-II
in pairs. This will cause them to lock up when a fault occurs on the fiber.
Only enable FiberAlert on the remote module
.
Link Fault Pass-Through
Link Fault Pass-Through (LFPT) is a troubleshooting feature that combines TX and FX
LinkLoss from both the local and remote iMcV-Giga-FiberLinX-II 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:
•
•
•
A cable fault occurs on the remote twisted pair.
TX LinkLoss detects the fault and disables the OPTICS (or UPLINK) port.
FX LinkLoss detects the fiber loss and disables the DATA port.
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.

Loopback Testing on Remote or Standalone
The following functions are available during loopback testing. During loopback
testing, management traffic entering the uplink port is still capable of managing the
device.
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.
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.
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.

VI - Using Telnet
You must assign the iMcV-Giga-FiberLinX-II an IP address before using a Telnet
session (this is not necessary when you are using UMA). Refer to the Assigning IP
Information section for more information. All of the configurations that you can
perform from the serial port can also be performed using a Telnet session. You can
only use one Telnet session at a time.
The three levels for Telnet account access are:
•
•
User–view status, change own password, and reboot.
Operator–all User privileges mentioned above, plus ability to change
settings.
•
Administrator–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.
Serial Port (EXT MGMT)
NOTE
The serial port is always set to Administrator level. Your password for Telnet
sessions is the password that you set and use in iConfig. Refer to iConfig on page
3 for more information.

Copper SFP settings in the Optics column may be different. In the Port Control
Settings area of the Port screen you can set the following:
Port Enable–Allows you to enable or disable the port. Both Port Enable and Admin
Status must be enabled (enabled and up) to enable the port. This setting can be
disabled from iView2.
Admin Status–Allows you to enable (Up) or disable (Down) the port. Both Port
Enable and Admin Status must be enabled (enabled and up) to enable the port. This
setting can be disabled from MIB-II compatible software.
Port Speed Ctrl–Allows you to set the port for autonegotiation or to force one of the
following speeds:

Advertise Ctrl–Selective advertising is used in combination with autonegotiation to
advertise your selected speed and duplex mode for the DATA and EXT MGMT ports.
This allows you to advertise all speeds and duplex modes. You must enable
autonegotiation 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 (FO), when connecting to
devices that can only autonegotiate. For the FO uplink versions, the port is
always force flow control 1000 FDX and cannot be changed.

NOTE
Default mode is the factory default and is provided as a starting point from which
to configure the iMcV-Giga-FiberLinX-II modules. This mode does not provide full
management isolation and is not recommended for normal use.
This section describes the Telnet/serial port screens and fields available for configuring
the iMcV-Giga-FiberLinX-II modes.
The iMcV-Giga-FiberLinX-II modes are configured using the config command from
the Device-Specific Options screen. This opens the Transparent Mode screen or the
VLAN Mode screen depending on the current configuration.
Transparent Mode
The Transparent Mode screen is displayed when the iMcV-Giga-FiberLinX-II module
is configured in Default mode or Transparent mode.
Transparent Mode – with either (not both) Data and Optics Mgmt DIP switches
set to on, all traffic passes between Optics and Data ports 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 DIP switches set to off,
all traffic passes between the Optics and Data ports.
Default Mode – the unit passes only Untagged Packets.
The unit is currently in Default Mode.
Enter Y for Transparent Mode, N for no Transparent Mode or <enter> to
move to other options [ Y ]

either 0 or 1000000000 will result in a limit of 1000 Mbps. When the received data
reaches the set limit in a one second interval, the unit stops receiving data. If flow
control is enabled, then flow control begins prior to reaching the set limit.
TX Bandwidth Limit–allows you to set the transmit bandwidth limit (up to 1000
Mbps) for both the DATA and OPTICS (or UPLINK) ports. Entering a setting of either
0 or 1000000000 will result in a limit of 1000 Mbps. When the transmit data
reaches the set limit in a one second interval, the unit stops transmitting data, but will
continue to receive until all the internal buffers are filled. If flow control is enabled,
then flow control begins before all the buffers are filled.

VII - Application Overview
Before using iMcV-Giga-FiberLinX-II in your network, decide the following:
•
Will iMcV-Giga-FiberLinX-II units be located at only one or at both ends of
the fiber?
•
•
How do you want to manage the iMcV-Giga-FiberLinX-II units?
Will you define VLAN IDs?
How many iMcV-Giga-FiberLinX-II units will you use?
•
•
Two for Host/Remote applications–allows IP-less management providing
greater security (only with an SNMP management module)
One for a single unit application–requires an assigned IP address for
management
How do you want to manage iMcV-Giga-FiberLinX-II?
You can manage iMcV-Giga-FiberLinX-II through any of its three ports (and any
combination thereof) or from the chassis. Using only the EXT MGMT port or UMA
provides the highest level of security. If management must be through either the
DATA port or UPLINK port, then a unique VLAN tag is recommended to maintain
security.

Will you define VLAN IDs?
When you want to use VLAN traffic with specific tags on any/all of the DATA ports,
you will need to disable Transparency and define VLAN IDs (refer to VLAN
Configuration section). When you want to use both VLAN tagged, untagged, or
double-tagged traffic, enable Transparency. When you want to use only untagged
traffic, set the unit to Default mode.
VIII - Application Examples
The following are application examples of the different VLAN configuration modes
available using the iMcV-Giga-FiberLinX-II. If you require assistance configuring an
application, email IMC Networks Technical Support at
The application modes include the following:
•
•
•
•
•
•
Default
Transparent with Untagged Management
Transparent with Tagged Management
Transparent with Extra Tagging (Q-in-Q)
Port VLAN
Port VLAN Filter
NOTE
When configuring VLAN IDs, remember that you can use any VLAN ID between 1
and 4,094. The VLAN IDs used in the following applications are for example
purposes only.
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.

Transparent with Untagged Management
Transparent with Untagged Management mode passes tagged traffic between the
DATA port and the OPTICS (or UPLINK) port and allows untagged traffic to be
considered management domain traffic (untagged).
To configure this mode, do the following:
1. Set the management DIP switch ON for the ports using management (in this
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)
2. Set Transparent Mode to allow both tagged data and untagged management
traffic to pass:
a. In the Main Configuration screen, press the space bar and type config. The
Configuration Screen displays:
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.
Default Mode – the unit passes only Untagged Packets.
The unit is currently in Default Mode.

Transparent 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 you
can 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:
1. Set the management DIP switch ON for the ports using management (in this
example it is the OPTICS (or UPLINK) 3 = ON and EXT MGMT 1 = ON).
2. Set Transparent Mode to allow both tagged and untagged traffic to pass:
a. In the Main Configuration screen, press the space bar and type config. The
Configuration screen displays:
Transparent Mode – with either (not both) Data and Optics Mgmt DIP switches
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.

IX - Troubleshooting
•
If two iMcV-Giga-FiberLinX-II Host/Remote units are not communicating
properly, make sure one is a Host (DIP switch #8) and the other is a
Remote (DIP switch #7). 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 you to perform a simple ping test. This is possible only if
pinging from the computer through the optics uplink port, which is highly
unusual. You must enable the EXT or data switch and connect to the
computer to ping either device.
•
•
If you cannot establish a link on a twisted pair port, ensure the cable is in
working order. If not, replace the cable (iMcV-Giga-FiberLinX-II includes
AutoCross; you should detect a link regardless of the Cat5 E cable type).
If you cannot establish a fiber link, ensure the fiber transceivers on iMcV-
Giga-FiberLinX-II are not over/under driving the fiber receivers. For fiber
Ensure the fiber mode and wavelength on both iMcV-Giga-FiberLinX-II units
match (i.e., both are 1310 nm single-mode fiber).
•
•
Ensure 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 autonegotiation, or if using Force
mode, ensure speed and duplex settings match.
If using single-strand fiber, ensure the pair of devices is compatible single-
strand fiber devices. For example, an iMcV-Giga-FiberLinX-II TX/SSFX-
SM1310-SC 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, ensure the installed SFP module is the correct
speed (1000 Mbps).
When using the FiberAlert feature, ensure 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, ensure that the DIP switch
settings are accurate for the port you want to manage.

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 you feel you
have configured the module improperly. If restarting to factory defaults is
necessary, IMC Networks recommends using this function on both units in
Host/Remote applications, and then reconfiguring all settings.
Ensure READ/WRITE Community Strings for iMcV-Giga-FiberLinX-II and
iView² are the same.

Troubleshooting LinkLoss/FiberAlert/Link Fault Pass-Through
The following diagrams show you how the different troubleshooting configurations for
the iMcV-Giga-FiberLinX-II.
The iMcV-Giga-FiberLinX-II also sends out link pulses from its copper and fiber
transmitters, but normally has no way of knowing whether the cable to the other
device is intact and the link pulses are reaching the other end. The combination of
FiberAlert and LinkLoss allows this information to be obtained, even when physical
access to a remote device is not available.

FX LinkLoss
Normally when a fault occurs on the fiber segment of an iMcV-Giga-FiberLinX-II
conversion, only the fiber port LEDs on the modules indicates a fault. None of the
devices connected to the RJ-45 ports are aware of the fault.
When FX LinkLoss is enabled on the iMcV-Giga-FiberLinX-II module, the fiber
fault is forwarded to that module’s RJ-45 connection. This turns off the link on the
RJ-45 port which can then be detected by the connected device.

TX LinkLoss
When a fault occurs on a twisted pair segment joining a device to an
iMcV-Giga-FiberLinX-II module, the link fault is not detected by the device connected
to the iMcV-Giga-FiberLinX-II module by fiber.
When TX LinkLoss is enabled on the remote iMcV-Giga-FiberLinX-II module, a twisted
pair fault turns off the fiber port transmitter. This allows the fiber-connected device to
detect a link fault. When the fiber uplink port is set to AN, the LED is OFF.

FiberAlert
***WARNING***
Do not enable FiberAlert at both ends. This can cause the fiber link to lock
up.
When FiberAlert is enabled on the remote module (preferred use), a fault on the
receive side of the OPTICS (or UPLINK) port causes the transmitter side to turn off.
This allows the fiber connected device to detect a fault in its transmission fiber.

Serial Port Pinout
The iMcV-Giga-FiberLinX-II features a serial port that uses an IBM-compatible DB-9
serial connector. To connect an iMcV-Giga-FiberLinX to your workstation, use a
straight-through (pin-to-pin) cable.
If your workstation has a serial port using a connection not compatible with a DB-9
COM port, use the pin connection chart for reference in making a cable.
Ensure the cable length is less than 50 ft. (15.24 m). Plug one end of the cable into
the DB-9 connector on the iMcV-Giga-FiberLinX and the other into the appropriate
port on your workstation.
Set your workstation for VT-100 emulation. The serial port on the workstation should
be set for:
