3.Safety Information
3.1 General Safety Information
Only trained and authorised personnel should be permitted to work on this equipment. It is
assumed that those using this guide are competent to work on equipment of this nature and will
take appropriate precautions when working with the fault analysis guide.
All devices should be inspected upon receipt for signs of physical damage, which may in turn, affect
operational performance, or the overall safety of the unit. Any damaged items should be returned
to Parallax Digital Technologies Ltd for safety checks.
Parallax Digital Technologies accepts no responsibility for any injury or loss caused by unsafe or
inadequate working practices, or for work carried out by an unauthorised third party.
To prevent possible danger, damage, and bodily harm when handling the equipment, please
observe all warnings, cautions notices contained in this section. Failure to heed the following
danger, warnings, and cautionary statements could lead to serious injury or death.
3.2 DC Power Supply
The Unit should be mains-fed using a DC Power Supply using an appropriately rated cable
assembly, which is protected internally at the power supply device itself. If the device is to be fed
from an alternative power source, then the appropriate circuit protection device should be used
to ensure that the supply circuit is interrupted, in the event that a fault in the device causes too
much current to flow into it, causing an unsafe condition.
4.Packing List
The following items are included in the shipping carton:
•1 x PDT-NSU-0008-MP-I Unmanaged Ethernet Switch
•1 x DIN Rail Mounting Kit (Fitted)
•1 x Wall Mounting Kit
•Operation & Maintenance Manual (May be electronically supplied)
•Declaration of Conformity (May be electronically supplied)

5.Product Overview
The PDT-NSU-0008-MP-I is an Unmanaged Ethernet PoE+ switch, providing 8 x 10/100 PoE+ RJ45
for connectivity, designed to directly connect to devices such as IP Cameras, Wireless APs, IP
Telephones etc.
This model operates from a nominal +48VDC power supply but can utilize supplies in the range
+48-57VDC.
The device is designed for use in harsh industrial environments, and incorporating a rugged
aluminium housing, it can be operated across a wide temperature range (-40°C to +80°C) making
it suitable for most conditions.
A typical application setup can be seen in the following diagram:

6.2 RJ45 Ports
The Front Panel has 8 RJ45 Ports and all are PoE+ compatible, with each port capable of supplying
30W each.

6.3 Power Supply Connector
The device is designed to be supplied by a +48VDC power supply, but can operate in the range +48-
57VDC. Power is supplied via a 6-pin terminal block connector with the following pinout
Note: All Power Supplies should provide over-current and short-circuit protection, and should have
a capacity rating to meet the required output current for the device plus any PoE powered device
requirements

7.Installation Procedures
7.1 DIN Rail Installation
7.2 Wall Mount Installation
Attach the DIN Rail Bracket (if not fitted) to
the switch case using the screws supplied
Clip the upper edge of the bracket onto the
DIN Rail and push to latch the bottom strip

8.Connection and Setup
8.1 Inspection Checks
Please inspect the unit to ensure that there is no damage to the external casing which could cause a
malfunction of the device or cause a safety critical fault. Any damaged units should be returned to Parallax
Digital Technologies for inspection and testing.
Please ensure that the DC Cables are securely fastened in the terminal block, and that the terminal block is
correctly inserted into the switch power connector housing.
8.2 RJ45 Connections
Ensure all required RJ45 Ports are connected correctly using CAT5e cable or better to the client devices.
The Uplink port should be connected to the host device or network, and the access ports are available for
other devices or connections. All cables should be solid copper and not CCA.
8.3 Power Up
The Unit will automatically power up as soon as DC power is applied to the device. The Power Light will be
illuminated and after approximately 1 second, all of the other LEDs will flash on and off to complete the
initialization sequence. Following this, the Port Status LEDs will display the current state of each of the
ports.
