1TECHNICAL SUMMARY
1.1 BRIEF DESCRIPTION
1.1.1 OVERVIEW
The OSD2144A is designed to convert between 10/100/1000Base-T copper cabling and 1000Base-Lx
fiber cabling. It has two fixed 10/100/1000Base-T RJ45 copper ports, and three SFP ports which can be
specified by the user for 10/100/1000Base-T, 100Base-Fx or 1000Base-X. The same unit will operate
on either singlemode or multimode fiber. Operation over at least 50km of singlemode fiber is possible
by use of the appropriate optical devices. It normally requires two fibers but is optionally available for
one fiber operation.
A major benefit of the OSD2144A is its reliable and consistent performance over the -20°C to +75°C
temperature range which allows it to be used in uncontrolled environments such as roadside cabinets,
mine sites and factories
1.1.2 APPLICATIONS

and three SFP ports which may be
either copper or fiber
▲ Supports network traffic of 1Gbps
▲ Can be used with either singlemode
or multimode fiber over a variety of
link budgets
▲ Available for operation over 1 or 2
fibers
▲ Automatic MDI/MDI-X: no need for
crossover cables

2.2.7 FITTING SFP CONNECTORS
Care should be taken when inserting/removing the SFP connectors from SFP port 3,4 and 5 as SFP
modules are Electrostatic (ES) sensitive and Electrostatic Discharge (ESD) precautions should be taken
when installing. Ensure that the SFP is fully engaged and latched into position.
Inserting SFP – Ensure that the SFP lever is in the locked position and insert into appropriate SFP
port. Gently push the SFP until it locks into place. Remove plastic/rubber dust cap and fit fiber cable or
RJ45 plug.
Removing SFP – Remove fiber connector or RJ45 plug. Pull the SFP lever down to unlock SFP from
housing. Using the lever, gently pull the SFP out.

2.3 OSD2144A OPERATION
When using the OSD2144A for the first time, check that the unit is in good condition with no visible
damage.
If a card version is used, insert it in an appropriate slot on the OSD370 or OSD350 chassis and check
that the indicators illuminate accordingly on power up (see Table 3). If a module version (OSD2144AC)
is used, connect the unit to an appropriate power source and check that the indicators illuminate
accordingly on power up (see Table 3).
2.3.1 CONNECTIONS
For RJ45 connection use Category 5 (CAT5) or higher. Length should be no more than 100 meters.
For singlemode fiber connections, fiber used must be 9/125µm singlemode fiber.
For multimode fiber connections, fiber used must be 50 or 62/ 125µm multimode fiber.
Plug in the appropriate connectors for system configuration;
–RJ45 cable to fixed copper ports (port 1 and 2) and copper SFP modules
–LC fiber cable to fiber SFP modules.
2.4 FIRMWARE UPDATES
All OSD2144A units will be shipped with the latest firmware already installed. The USB port is used
for any firmware updates. To enable the OSD2144A for firmware updates, switch 4 will need to be
toggled to the ‘on’ position before unit is powered on. Upon completion of firmware updating, toggle
switch 4 to the ‘off’ position and power the unit on again.

3MAINTENANCE
3.1 INTRODUCTION
The following section outlines the fault-finding procedure for the OSD2144A modems. Please take
note of the following:
▲ Personnel without appropriate training should not attempt any maintenance except that outlined
below.
▲ If further maintenance is attempted you are warned that every care should be taken to ensure that
internal measurements made while the equipment is operational are taken carefully as some
components within the unit are expensive and may be damaged by failure of any portion of their
support circuitry.
▲ Some components within the unit are Electrostatic (ES) sensitive and Electrostatic Discharge
(ESD) precautions should be taken when performing maintenance upon the unit.
3.2 EXTERNAL INSPECTION
Visually check for the following:
▲ Check that the correct power source is connected to the power socket.
▲ Check that the Ethernet cables are connected to the modem correctly and that the distant
OSD2144A modem has been connected correctly to any external equipment.
▲ Inspect the optical connectors (for fiber SFP option) for any contamination and clean using
isopropyl alcohol and a lint free tissue if any contamination is detected.
3.3 ROUTINE MAINTENANCE
▲ There is no routine maintenance required with the OSD2144A
