1TECHNICAL SUMMARY
1.1 BRIEF DESCRIPTION
1.1.1 OVERVIEW
The OSD2155 is a 10/100/1000BaseT Ethernet Media Converter supporting Jumbo Frames. It has one
RJ45 copper port and one SFP port which can be specified by the user for one or two fiber
configuration.
The unit will operate on either singlemode or multimode fiber by use of the appropriate optical device.
A major benefit of the OSD2155 is its reliable operation over the -20°C to +75°C temperature range
which allows it to be used in environments such as roadside cabinets, mine sites and factories.
The OSD2155 module is intended for isolated use and requires an external power source.
1.1.2 APPLICATIONS

▲ Auto MDI/MDIX.
▲ Can be used with either singlemode or
multimode fiber over a variety of link
budgets

This section outlines the methods required to install and operate the OSD2155 successfully. It should be
studied carefully if damage to the equipment or poor results are to be avoided.
This equipment has been fully tested prior to dispatch and is ready for immediate operation. However it
is advisable to check for external transportation damage before operation. If damage is evident, return
the unit with the packaging to your supplier immediately.
2.2 INSTALLATION
2.2.1 WARNING AND PRECAUTIONS
▲ ELECTROMAGNETIC COMPATIBILITY
WARNING: This is a Class A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.
▲ OPTICAL OUTPUT OPERATION
WARNING: Laser Safety: Class 1 Laser Product per IEC/EN 60825-1:2014 standard.
Class 1

2.2.2 OSD2155 DRAWINGS AND DIMENSIONS
The standard OSD2155 is designed to be mounted and powered from either the OSD350 or OSD370
19” 3RU Chassis.
FIGURE 3: DIMENSIONS
2.2.3 POWER SUPPLY CONNECTIONS
The OSD2155 requires external DC power. The voltage range of the OSD2155 is +11V
DC
to +13V
DC
.
Which is powered from the OSD370 or OSD350 chassis. DC power is connected via the DB9

2.2.4 LOCATION
As with any electrical device, the OSD2155 together with the OSD370/OSD350 chassis should be
placed where the unit will not be subjected to extreme temperatures, humidity, or electromagnetic
interference. Specifically, the site selected should meet the following requirements:
•The ambient temperature should be between -20°C to 75°C (-4°F
to 167°F).
•The relative humidity should be less than 95 percent, non-condensing.
•Surrounding electrical devices should not exceed the electromagnetic field (RFC) standards.
•Make sure that the switch receives adequate ventilation. Do not block or obstruct the
ventilation holes on the chassis.
2.2.5 FIXED RJ45 COPPER PORT PIN ASSIGNMENTS
Figure 5 shows the pin configuration for the fixed RJ45 copper port.
FIGURE 5: FIXED RJ45 ETHERNET CONNECTORS
2.2.6 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 11 is an example of a copper connection loss. The OSD2155 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 11: COPPER CONNECTION LOSS
Figure 12 is an example of a fiber connection loss. If the OSD2155 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 OSD2155 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 PSE power
requirements do not exceed the OSD2155 modems maximum PD power.
▲ Inspect the optical connectors (fiber SFP) 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 OSD2155.
