1. Introduction
All Antaira industrial managed switches come with a pre-installed “user-friendly” web console
interface, which allows users to easily configure and manage the units, whether one is using a serial
console and Command Line Interface (CLI) commands like Telnet, SSH, HTTP (Web GUI) or Simple
Network Management Protocols (SNMP).
1.1Product Overview
Antaira Technologies’ LMP-1204G-SFP-bt series is a 12-port industrial Gigabit PoE++ managed
Ethernet switch embedded with 4*10/100/1000Tx Ethernet ports that support IEEE 802.3bt for a
maximum of 90W/port, 4*10/100/1000Tx Ethernet ports that support IEEE 802.3af/at for a maximum
of 30W/port, and 4*100/1000Fx fiber connection. The LMP-1204G-SFP-bt series is a fully
manageable Light Layer 3 Ethernet switch that is pre-loaded with a user-friendly web management
console design. It supports the ring network redundancy function using the market’s open standard
ITU-T G.8032 ERPS (Ethernet Ring Protection Switch) protocol that has a <50ms network recovery
time. The advanced network filtering and security functions, such as IGMP, VLAN, QoS, SNMP,
RMON, Modbus TCP, and 802.1X/HTTPS/SSH/SSL increase determinism and improve network
management for remote SCADA systems or control networks.
The LMP-1204G-SFP-bt series is IP30 rated and DIN-rail mountable. There are also two wide
operating temperature models for either a standard temperature range (STD: -10°C to 65°C) or an
extended temperature range (EOT: -40°C to 75°C). It also provides high EFT and ESD protection for
industrial networking applications, such as power/utility, water wastewater, oil/gas/mining, factory
automation, security surveillance, ITS and any other outdoor or harsh environment.

2.5 PoE Port LED Indicators
The LED light indicators on the PoE copper port can help the user know if an event once occurs or is happening.
When the event is happening, user can verify the event from the Dual-color LED status. If the port has recovered
from an event, user 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 overload (>100%), the PoE port of the lowest priority PoE port will be shutdown. The
PoE LED of the port will act cyclically as below until the port is recovered from the event:
After the PoE port is recovered from the PoE budget overload event, the PoE LED of the will act cyclically as
below until the event indicator is clear manually:

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:
**AF/AT: Amber; BT: Green
•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:
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:

The relay contact alarm will be triggered when anyone 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
[Notice]
When the relay is triggered because of Event 2~5, the relay contact alarm, will update the status every 30
seconds. If there’s no event happening for 30 seconds, the relay contact alarm will be turn off. If the user disables
the failed PoE port by removing the cable or Dip Switch manually, the relay will be recovered immediately.
2.8 Reset Button
There is a ‘Reset’ button located on the front panel of the industrial Ethernet switch that helps users
to reboot, restore default, or save start-up configurations by pressing the button for different
seconds. Please refer to Table 2.2 for the timing and function.

2.10 Cabling
Use the four twisted-pair, category 5e, or the above cabling for the RJ-45 port connections. The cable
between the switch and the link partner (switch, hub, workstation, etc.) must be less than 100 me ters (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 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.
2.11 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 2.6.
Figure 2.6
Power Terminal Block

2. Tighten the wire-clamp screws to prevent the wires from loosening, as shown below in Figure 2.7.
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.

2.12 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 2.8. By
inserting the wires, it will detect the fault status including power failure or port link failure (managed industrial switch
only) and form a normal open circuit. An example is shown below in Figure 2.8.
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.
2.13 Grounding Note
Grounding and wire routing help limit the effects of noise due to Electromagnetic Interference (EMI). Run the
ground connection from the ground screw to the grounding surface prior to connecting devices. The grounding
screw symbol is shown below in Figure 2.15.
Figure 2.15 - Grounding screw symbol
Caution: Using a shielded cable achieves better electromagnetic compatibility.
Attention: L'utilisation d'un câble blindé permet une meilleure compatibilité électromagnétique
