2 INSTALLATION AND OPERATION
2.1 INTRODUCTION
This section outlines the methods required to install and operate the OSD2254EP
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
The OSD2254EP 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.

2.2.2 DRAWINGS AND DIMENSIONS
The OSD2254EP is designed to be wall mounted onto a DIN-Rail (35mm top hat) fixture or by
using 4 x M4 captivated screws (DIN Rail mount requires removal and flanges repositioned –
see below). The unit dimensions (excluding connectors, SFPs, etc) is shown in Figure 3
below.

OSD2254EP Operator Manual
2.2.3 LOCATION
As with any electrical device, the OSD2254EP should be placed where the switch 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 -40°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 OSD2254EP 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 OSD2254EP 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 OSD2254EP switch and then turn power on.
Step 2: Disconnect the power if you want to shut down the switch.

2.2.5 ALARM CONNECTION
The OSD2254EP has two monitoring alarm outputs: 1) Ring to Bus Alarm and 2)
Temperature Alarm. The alarm connections and conditions for alarm outputs are as set out in
Table 3. There are four pins on the 3.5mm terminal block used alarm output. Maximum
ratings the OSD2254EP relay can drive is 100mA @ 46V(max). Note: Alarm output has no
polarity.

2.2.6 USB CONNECTOR
The OSD2254EP 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 OSD2254EP via the PC’s USB
connector. See section 2.4 for further CLI information.
FIGURE 7: USB TYPE B CLI PORT
To operate and control the OSD2254EP using the CLI, a proprietary driver will be required to
be installed onto the PC being used. The driver can be found and downloaded via the
following site: www.silabs.com and searching for the CP210x driver. Download the relevant
driver for your operating system, install and follow the installation instructions from your PC.

rules are as follows:
For 60W device:
One PoE channel provides power (mode 001, 010): Max output power is 45W
Two PoE channels provide power (mode 100, 101, 110): Max output power is 70W
For 90W device:
One PoE channel provides power (mode 001, 010): Max output power is 45W
Two PoE channels provide power (mode 100, 101, 110): Max output power is 90W
For 802.3at/af standard mode (000), power limitation follows the classification result ie
802.3at/af standard.
For reserved modes (011, 111), PoE function is disabled on each port.

2.2.10 FITTING SFP CONNECTORS
Care should be taken when inserting/removing the SFP connectors from SFP port 5 and 6 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 OPERATION
When using the OSD2254EP 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 OSD2254EP connected in a redundant ring topology providing maximum reliability on
critical networks (up to 64 nodes per ring). 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.
FIGURE 14: REDUNDANT RING CONFIGURATION

PAGE 20 10115208
OSD2254EP Operator Manual
To connect the OSD2254EP 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 15 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 OSD2254EP 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. Note: connection diagram is for
illustrative purposes only. Port 5/6 can be connected in to either port to achieve redundant
ring configuration.
FIGURE 15: REDUNDANT RING CONNECTION
Bus Operation
To connect the OSD2254EP 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.)
