1TECHNICAL SUMMARY
1.1 BRIEF DESCRIPTION
1.1.1 OVERVIEW
The OSD2151 is designed to convert between 10/100/1000Base-T copper cabling and 1000Base-Fx
fiber cabling with the added feature of Link Loss Forwarding. It has one RJ45 copper port and one SFP
port which can be specified by the user for one or two fiber configuration.
The OSD2151 incorporates Link Loss Forwarding (LLF) function providing fault detection and shut
down when a link fails.
The unit will operate on either singlemode or multimode fiber. Operation over at least 500m of
multimode fiber or 50km of singlemode fiber is possible by use of the appropriate optical devices.
A major benefit of the OSD2151 is its reliable operation over the -20°C to +65°C temperature range
which allows it to be used in environments such as roadside cabinets, mine sites and factories.
1.1.2 APPLICATIONS
▲ Any network utilising a mix of copper
and fiber
▲ Industrial IP communications
▲ Gigabit Ethernet backbone networks
1.1.3 FEATURES AND BENEFITS
▲ Complies with
IEEE802.3i/802.3u/802.3ab
10/100/1000Base-T, IEEE802.3z
1000Base-Lx/Sx standards.
▲ Supports network traffic of up to
1000Mbps.
▲ Has one fixed 10/100/1000BaseT
copper port and one Gigabit SFP port
which may be either copper of fiber
▲ Automatic MDI/MDIX setup: no need
for crossover cables.
▲ Can be used with either singlemode or
multimode fiber over a variety of link
budgets
▲ Advanced features like Link Loss
Forwarding to detect the link status of
link partners either on the fiber and/or
copper port.
▲ Available for operation over 1 or 2
fibers.
▲ Powered by non critical 12V
DC
or
24V
AC
supplies
▲ Operates over the temperature range
of -20 to +65°C

2.2.7 FITTING SFP CONNECTORS
Care should be taken when inserting/removing the SFP connectors from the SFP port 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 appropriate
fiber cable.
Removing SFP – Remove fiber connector. Pull the SFP lever down to unlock SFP from housing.
Using the lever, gently pull the SFP out.

Examples
Figure 12 is an example of a copper connection loss. The OSD2151 will detect that there is no copper
connection received and then disable the transmission to the fiber port. The 1000Base-X switch will
thus be notified that there has been a copper link loss.
FIGURE 12: COPPER CONNECTION LOSS
Figure 13 is an example of a fiber connection loss. If the OSD2151 does not receive a valid optical
signal from the switch, transmission to copper port will be disabled.

3MAINTENANCE
3.1 INTRODUCTION
The following section outlines the fault-finding procedure for the OSD2151 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 OSD2151
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 OSD2151.
