Introduction
About FiberLinX
FiberLinX from IMC Networks is an IEEE 802.3 compliant, SNMP-
manageable media converter/LAN extender/Ethernet bridge that can be
managed remotely. FiberLinX is designed to convert between 10 Mbps
Ethernet twisted pair (10Base-T) and 10 Mbps Ethernet (10Base-FL) single-
mode or multi-mode fiber optic cabling.
Each FiberLinX features the following three ports:
10Base-T data port
10Base-FL data port
10Base-T port specifically
for SNMP traffic (i.e., the
management port).
NOTE: Although the
management port is designed to
accept SNMP traffic, ANY port on the FiberLinX Module can be configured to
serve as the SNMP management port.
NOTE: The twisted pair management port is not designed to handle data
traffic, and therefore should NOT serve as a redundant twisted pair port.
The primary advantage of FiberLinX is that it allows the administrator to
completely monitor and manage fiber traffic between switches and routers
while remaining isolated from the remote (or customers) network.

About FiberLinX Modules
FiberLinX Modules can be installed into any IMC Networks
PowerChassis/100-Series. The following versions of FiberLinX Modules are
available:
FiberLinX  10Base-T twisted pair and 10Base-
FL 850 nm multi-mode fiber; includes
two RJ-45 connectors and one pair ST
or SC connectors.
FiberLinX 1300  10Base-T twisted pair and
10Base-FL 1300 nm multi-mode fiber;
includes two RJ-45 connectors and one
pair ST or SC connectors.
FiberLinX-SingleMode  10Base-T twisted pair
and 10Base-FL 1300 nm single-mode
fiber; includes two RJ-45 connectors
and one pair ST or SC connectors.
FiberLinX-SingleMode/PLUS  as above with
higher power budget.
How FiberLinX Works
Each port on the FiberLinX includes its own MAC Address. The movement
of data from one port to another is
accomplished via packet switching.
The destination address of each
Ethernet packet entering the
FiberLinX is checked to determine
whether it is a management packet
or a downstream data packet, and
is switched appropriately. Packets
not addressed for management
ports are sent through to the
network. Similarly, management
packets are switched internally to
the management engine and are
not forwarded.
More information about how FiberLinX works can be found on the IMC
Networks Web site at www.imcnetworks.com.

Hardware Installation
Installing a FiberLinX Module involves the following steps:
1) Configuring the FiberLinX Module via its eight-position Dip
switch for the following:
lHalf/Full Duplex setting (data ports only),
ldesignating the management traffic port,
lhost/remote or standalone operation;
2) Installation of a PowerChassis/100-Series chassis;
3) Installation of the FiberLinX Module into the above-mentioned
PowerChassis; and,
4) Selecting a crossover or pass-through connection for the twisted
pair data port.
Configuring FiberLinX Modules
FiberLinX Modules have an eight-position Dip switch, located at position
S2 (shown below), for configuring the module.
Figure 2.1 Dip Switch Location on FiberLinX
(default settings shown)
2.1

The following table shows the function for each of the eight Dip switches
on FiberLinX. Refer to the section on each feature for specific configuration
information.
Switches 1 & 2: Fiber Optic Type
These Dip switch settings are configured at the factory and should NOT
be changed in the field.
Switches 3 & 4: Selecting Duplex Mode
Each data port on FiberLinX can operate in either Half-Duplex (HDX) or
Full-Duplex (FDX) Mode. (NOTE: The Twisted Pair management port is
ALWAYS Half-Duplex.) You will need to set the duplex mode of these ports
depending on the capabilities of the connected hardware.
FiberLinX is shipped from the factory with HDX selected on each data port
(i.e., Dip switches 3and 4in the OFF position). Select FDX for the fiber
data port by setting Dip switch 3to ON. Select FDX for the twisted pair data
port by setting Dip switch 4to ON.
Switches 5 & 6: SNMP Management Traffic
Although FiberLinX provides a twisted pair port solely for management
traffic, you can configure FiberLinX to accept SNMP management traffic from
any of its three ports. There are four different ways you can configure
FiberLinX to accept (or not accept) SNMP management traffic. Only one
source for SNMP management traffic can be active at any time, and only the
SNMP management traffic directed to the modules IP address will be
accepted.
FiberLinX is configured at the factory to accept SNMP management traffic
from the twisted pair data port (i.e., Dip switch 5ON, Dip switch 6OFF).
You can change this setting by adjusting Dip switches 5and 6. The
following table shows the switch settings for each configuration.

Switches 7 & 8: Configuring FiberLinX as a Host, Remote
or Standalone Unit
When two FiberLinX units are paired with one another, each FiberLinX
unit can be configured to be either a Host unit or a Remote unit. As a Host,
FiberLinX requests management information from any attached remote unit
and displays that information, along with its own, upon SNMP query. As a
Remote, FiberLinX will not respond to requests for management information
from an attached unit. In single installation, the sole FiberLinX should be
configured as standalone unit (factory default). Following is a table showing
the Dip switch configurations for each setting. Please see Chapter 4 of this
guide for possible installations and their related Host, Remote and
standalone Dip switch settings.
Configure FiberLinX to be a Host unit by setting Dip switch 8to ON.
Configure FiberLinX to be a Remote unit by setting Dip switch 7to ON.
FiberAlert
Since media converters are a transparent link in a network, FiberLinX
features FiberAlert, a troubleshooting feature that assists in pinpointing link
faults between media conversion products. If a media converter is not

receiving a fiber link, FiberAlert disables the media converter's fiber
transmitter, thus mirroring the link status of the opposite end of the fiber.
Both fiber link LEDs on either side of the devices should extinguish, alerting
you to the fault.
NOTE: FiberAlert should only be activated on one side of a media
conversion.
More information on FiberAlert can be found on the IMC Networks Web
site at www.imcnetworks.com/to-fa.htm.
Installing a FiberLinX Module
Once you configure a FiberLinX Module, it is ready to be installed in a
chassis. You can install a FiberLinX Module into any IMC Networks
PowerChassis/100-Series chassis (e.g., PowerChassis/101, etc.). FiberLinX
Modules may be safely installed or removed with power on (i.e., FiberLinX
Modules are hot-swappable). Please read the electrostatic discharge
precautions on page 5.1 of this manual before proceeding
NOTE:FiberLinX Modules should be installed into a PowerChassis
only AFTER the PowerChassis has been installed. Please see the
installation guide included with your chassis for assistance in installing
the chassis.
PowerChassis come with blank brackets covering the slots where the
modules are to be installed. To install a FiberLinX Module, remove the blank
bracket by loosening the screws located on the outside edges of the bracket.
Slide the FiberLinX Module into the chassis until the module is seated
securely in the connector. Secure the module to the chassis by tightening
the captive screws.
