LNP-C501G-SFP-bt Series - Hardware Manual - v1.0
1 Overview
Antaira Technologies’ LNP-C501G-SFP-bt series is a compact 5-port industrial gigabit PoE++ unmanaged Ethernet switch.
The small form factor of this metal IP40 rated design is 50% smaller which allows for a more versatile implementation.
The LNP-C501G-SFP-bt series is equipped with 4*10/100/1000Tx Ethernet ports that support IEEE 802.3bt for a maximum
of 90W/port and 1*100/1000Tx SFP port. The LNP-C501G-SFP-bt series can handle high bandwidth applications in tight
spaces. The LNP-C501G-SFP-bt series supports high EFT & ESD protection through the redundant power inputs that
support reverse polarity and overload current protection. This product series supports DIN-rail as well as wall mountable
orientations and provides operating temperature range models in STD: -10°C to 65°C and EOT: -40°C to 75°C. This is an
industrial grade unit applicable for networking applications in factory automation, ITS, power/utility, water wastewater
treatment plants, or any application that needs a compact solution.

2.4 PoE Port LED Indicators
The LED light indicators on the PoE copper port can help the user know if and when an event immediately occurs or is
happening. When the event is happening, you can verify the event from the Dual-color LED status. If the port has recovered
from an event, you can verify the event from the blinking frequency of the PoE LED (5 seconds as a cycle).
Power Budget Exceeded Event
When the total PoE budget is overloaded (>100%), the PoE port of the lowest priority PoE port will be shut down. The PoE
LED of the port will act cyclically as below until the port is recovered from the event:
Figure 2.3 - PoE Budget Overloaded LED Sequence
After the PoE port is recovered from the PoE budget overload event, the PoE LED of the port will act cyclically as below
until the event indicator is clear manually:
Figure 2.4 - PoE Budget Recovering LED Sequence
**IEEE 802.3af/at: Amber
**IEEE 802.3bt: Green
PoE Port Over Current Event (PoE Port Overload Event)
When the current limit of the specific PoE port is exceeded, the PoE power will be shut down. The PoE LED of the port will
act cyclically as below until the port is recovered from the event:

Cable Short Event
When the working PD encounters a cable short event, the PoE port LED will act cyclically as below until the port is
recovered from the event:

After the PoE port is recovered from the Cable Short event, the PoE LED of the port will act cyclically as below until the
event indicator is clear manually:

Dual PD Fail Event
When one channel of the connected dual PD is failed, the failed channel will be shut down and the active channel will still
supply PoE to the connected PD. The PoE Port LED will act cyclically as below until the port is recovered from the event:
Figure 2.9 - PoE Dual PD Failed LED Sequence
After the PoE port is recovered from the Dual PD Fail event, the PoE LED of the port will act cyclically as below until the
event indicator is clear manually:

**IEEE 802.3af/at: Amber
**IEEE 802.3bt: Green
*Note:
1. The system will automatically retry to recover from the event failure every 20 seconds.
2. To clear the warning PoE Indicator of the recovered port, please replug the port cable or reopen the PoE function of the
port via DIP switch (≥ 2 sec.)

2.6 Relay Contact Alarm Warning
2-pin 1*24VDC@1A resistive normal open on 6-pin terminal block.
The relay contact alarm will be triggered when any one of the listed events occurs.
Key trigger event 1: Power 1 or Power 2 is inactive
Key trigger event 2: PoE total loading > 100% PoE output budget
Key trigger event 3: PoE over current per port
Key trigger event 4: Cable short per port
Key trigger event 5: One of the channels in Dual PD fail
* Note:
When the relay is triggered because of event 2~5, the relay contact alarm will update the status every 30 seconds. If there
is no event happening for 30 seconds, the relay contact alarm will be turned off. If the user disables the failed PoE port by
removing the cable or DIP switch manually, the relay will be recovered immediately.
2.7 Ethernet Ports
●RJ45 Ports
RJ45 Ports (Auto MDI/MDI-X): The RJ45 ports are auto-sensing for 10Base-T, 100Base-TX, or 1000Base-T connections.
Auto MDI means that the switch can connect to another switch or workstation without changing the straight-through or
crossover cabling. See the figures below for straight-through and crossover cabling schematics.

Note: “+” and “-” signs represent the polarity of the wires that make up each wire pair.
2.8 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the RJ45 port connections. The cable between the switch
and the link partner (switch, hub, workstation, etc.) must be less than 100 meters (328 ft.) in length.
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications for both
telecommunication and data communication applications.
Caution: Please employ an optional optical transceiver (SFP/Fixed Fiber) that complies with IEC 60825-1 and
classified as Class 1 laser product.
Attention: Veuillez utiliser un émetteur-récepteur optique en option (SFP/fibre fixe) conforme à la norme IEC
60825-1 et classé comme produit laser de classe 1.

2.9 Wiring the Power Inputs
Caution: Please follow the steps below when inserting the power wire.
Attention: Veuillez suivre les étapes ci-dessous lors de l'insertion du câble d'alimentation.
1. Insert the positive and negative wires into the PWR1 (V1+, V1-) and PWR2 (V2+, V2-) contacts on the terminal block
connector as shown below in Figure 2.11.
Figure 2.11 - Power Terminal Block
2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in Figure 2.12.
Figure 2.12 - Power Terminal Block
Caution:
Only use copper conductors, 125°C, tighten to 5 lbs.
The wire gauge for the terminal block should range between 18~20 AWG.
Attention:
Utilisez uniquement des conducteurs en cuivre, 125°C, serrez à 5 lb.
Le calibre des fils du bornier doit être compris entre 18 et 20 AWG.

2.10 Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of the terminal block connector as the picture shows below in Figure 2.13. By
inserting the wires, it will detect the fault status including power failure or port link failure (managed industrial switch
only), and form a normally open circuit. An example is shown below in Figure 2.13.
Figure 2.13 - Wiring the Fault Alarm Contact
Caution:
The wire gauge for the terminal block should range between 12 ~ 24 AWG.
If only using one power source, jumper Pin 1 to Pin 5 and Pin 2 to Pin 6 to eliminate power fault alarm.
Attention:
Le calibre des fils du bornier doit être compris entre 12 et 24 AWG.
Si vous n'utilisez qu'une seule source d'alimentation, connectez les broches 1 à 5 et les broches 2 à 6 pour
éliminer l'alarme de panne de courant.
