1TECHNICAL SUMMARY
1.1 BRIEF DESCRIPTION
1.1.1 OVERVIEW
The OSD2254P is a 6-port industrial switch with redundant ring Gigabit Ethernet and PoE++ Source
providing simple network management with real-time monitoring. It has four 10/100/1000Base-T RJ45
copper ports and two SFP ports for ring/bus configuration.
The OSD2254P incorporates redundant ring technology providing maximum reliability on critical
networks. In the event of device or fiber failure the data path will automatically switch to a secondary
path in less than 2ms per hop to maintain ring network integrity.
The OSD2254P has Power over Ethernet++ (PoE++) function and operates as a Power Source
Equipment (PSE). The OSD2254P PoE++ can provide up to 60W to each RJ45 port to Powered
Devices (PD). The unit will operate on either singlemode or multimode fiber. Operation over a network
of hundreds of kilometers is possible by use of the appropriate optical devices. It normally requires two
fibers but is optionally available for one fiber operation per port.
A major benefit of the OSD2254P is its reliable and consistent performance over the -20°C to +75°C
temperature range that allows it to be used in uncontrolled environments such as roadside cabinets,
mine sites and factories.

2INSTALLATION AND OPERATION
2.1 INTRODUCTION
This section outlines the methods required to install and operate the OSD2254P 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 60825-1:20011 standard.
Class 1
The OSD2254P is a Class 1 laser product.
PRECAUTIONS
▲ All service personnel should be provided training as to the hazards of direct viewing of laser
radiation and of the precautionary measures during servicing of equipment
▲ Areas where laser products are installed should be restricted in access to trained service
personnel only and appropriate warning signs posted in the work area.
▲ All laser apertures should be covered by protective covers when not connected to optical
fibers. Never leave outputs uncovered.
▲ Laser equipment should be positioned above or below eye level where possible. Apertures
should be positioned away from personnel.
▲ Protective eyewear should be worn in the vicinity of laser equipment.

2.2.3 LOCATION
As with any electrical devices, the OSD2254P should be placed where it 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.
•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 the ventilation holes on
any side of the switch.
Note: Without proper cooling and control (lowering) of ambient temperature, the components within
the OSD2254P can be subject to increased heat shortening the longevity and reliability. It is thus good
engineering practice to ensure the unit is installed in a well ventilated area.
2.2.4 POWER SUPPLY CONNECTIONS
The OSD2254P requires external power to the Redundant DC Terminal Block Power Connector
located at the top of the unit. Always ensure that the power is off before any installation.
Redundant DC Terminal Block Power Inputs
There are two pairs of power inputs for use with redundant power sources. Only one power input is
required to be connected to run the switch.
Step 1: Connect the DC power to the appropriate power source, connect the plug-able terminal block
on the OSD2254P switch and then turn power on.
Step 2: Disconnect the power if you want to shut down the switch.

2.2.6 USB CONNECTOR
The OSD2254P has a USB – Type B connector located on the bottom of the unit that is used for
Command Line Interface (CLI) from the PC to the OSD2254P via the PC’s USB connector. See
section 2.5 for further CLI information.
FIGURE 7: USB TYPE B CLI PORT
To operate and control the OSD2254P using the CLI an OSD2254P driver will be required to be
installed onto the PC being used. The driver can be found on the included CD or on the OSD website.

TABLE 6: CURRENT LIMITING SWITCH SETTINGS
Some PD devices are non-standard and require current limiting to function and not damage equipment.
It is advised to check PD device current requirements and set the current limits according to Table 6.
2.2.9 FITTING SFP CONNECTORS
Care should be taken when inserting/removing the SFP connectors from SFP port 3 and 4as 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 OSD2254P OPERATION
When using the OSD2254P for the first time, check that the unit is in good condition with no visible
damage.
Upon power up check that the indicators illuminate accordingly on power up (see Table 4).
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 50/125µm 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 or SC fiber cable to fiber SFP modules.
Redundant Ring Operation
The OSD2254P connected in a redundant ring topology providing maximum reliability on critical
networks. In the event of device or fiber failure the data path will automatically switch to a secondary
path in less than 2ms per node to maintain ring network integrity.

OPTICAL SYSTEMS DESIGN
DOC ID: 10115206
OSD2254P OPERATOR MANUAL
PAGE 19
To connect the OSD2254P in a redundant ring configuration ports 5 and 6 must be used together with
fiber SFPs. The non-ring ports (ports 1,2,3,4) should be used to connect to your Ethernet devices (eg.
Cameras, PLCs, computers, etc.)
Figure 14 shows the connection method. Typically the SFP used would be a fiber SFP with duplex LC
connectors. The dashed line indicates the closed loop, but more OSD2254P units can be connected to
the ring as required using this topology. Ensure that the switch settings for port 5 and 6 are set to
1000Mbps (1Gbps) – see Table 5.
FIGURE 14: REDUNDANT RING CONNECTION
Bus Operation
To connect the OSD2254P in a bus configuration ports 5 and 6 must be used together with fiber SFPs.
The remaining ports (ports 1,2,3,4) should be used to connect to your Ethernet devices (eg. Cameras,
PLCs, computers, etc.)
