Operation

5 Operation
5.1 Preparations
T Unpacking the Gigabit PoE Supply.
T Save packaging for later transport and storage.
T Check the packaging and the Gigabit PoE Supply for visible damage.
T When visible damage to the packaging and/or delivered parts is detected:

Contact the salesperson or Neutrik sales partner.
T Do not use damaged devices under any circumstances.

5.2 Connecting devices with the Gigabit PoE Supply
The Gigabit PoE Supply is installed as a midspan device between the PoE powered device and a
Ethernet device without power output.
• For a load of 20 W or higher, it is mandatory to use AWG24 or higher cross-section

cables.
• For cable lengths of 50 m or longer, it is mandatory to use AWG24 or higher cross-section

cables.
• F / UTP Kat 6A cables are recommended.

(F / UTP cables can better dissipate heat due to the screen)
w NOTE
Risk of device damage!
T Do not combine NPS-30W Gigabit PoE Supply with other PoE Supplies, as this can cause adamage to the powered device due to different pin assignment.
T When using 2 NPS-30W PoE Supplies, do not use cables with different connection standards(TIA568A vs TIA568B). Never use Ethernet Cross-cables within PoE connections.
T Connect the devices depending on the desired application.
T Connect the Gigabit PoE Supply with the power supply.
 LEDs light up once the Gigabit PoE Supply is supplied with power.
 The Gigabit PoE Supply is ready for operation.

7.2 PoE (Power over Ethernet)
PoE stands for Power over Ethernet and describes a practice for using a single CAT5e (or higher) to incorporate both
power and data in the single cable.
Few advantages:• Easy setup• Single cable run up to 100 m• Using PoE doesn’t require certified electrician as the power loads are small• Existing network infrastructure can be used

7.2.1 Definitions
PD (Powered device) – device that is connected to PSE and thus is powered by it.
PSE (Power Sourcing Equipment) – device that provides power to PD, can be a network switch or injector.
PSE Types
In our case, we consider only following two types of PSE devices.
• PoE Switch: a switch that offers possibility to power PD. Switches use PoE classification.
• PoE Injector: typically a single port device for powering 1 PD. These exist with classification (active) or without(passive). Neutrik's NPS-30W is a passive PoE injector.
The term class refers to a maximal power output (see table below).

User Manual – Gigabit PoE Supply NPS-30W | BDA 579 V2 2020/08

Appendix

7.2.2 PoE Standards
These standards are part of IEEE 802.3 general standards.
802.3 af – defines PoE classes 0-3.
802.3 at – uses the same classes, but introduces class 4 as well.
802.3 bt – uses the same classes as 802.3 af and 802.3 at, but introduces class 5 to 8 as well.

7.2.3 Classes and discovery process
Discovery is a process of PSE, determining the power requirements of the PD. Once PD and PSE are connected, PSE
sends out a short voltage impulse, reads the returned value and provides power accordingly. This is valid for PSE withclass (also called active).
No class (passive) PSE, acts as a classic power supply, hence no discovery is implemented, and PSE supplies deliver current at all times.
