3.1 Tauler frontal
Figura 3.1: Frontal view of the JetNet 2005 showing the five Ethernet ports (P1-P5), Power (P) LED, and Alarm (Alm) LED.
The front panel of the JetNet 2005 features five 10/100Mbps Ethernet ports labeled P1 through P5. Each port has an associated LED indicator for link/activity status. Above the ports, there are two system LEDs: 'P' for Power status and 'Alm' for Alarm status.
3.2 Side Panel (DIP Switches and Power Input)
Figura 3.2: lateral view of the JetNet 2005, highlighting the DIP switches for port alarm configuration and the DC24V power input terminal.
One side of the device houses the DIP switches, labeled 1 through 5, which are used to configure the port alarm function. Below the DIP switches, the power input terminal is located, designed for DC18-32V power supply, along with a ground connection.
3.3 Panell posterior

The rear panel provides product identification details, including the model name (JetNet 2005), serial number, and hardware version. It also displays various compliance markings such as CE, FCC, and RoHS, indicating adherence to international standards.
4. Configuració i instal·lació
4.1 Muntatge en carril DIN
The JetNet 2005 is designed for easy installation on a standard DIN rail. Ensure the DIN rail is securely mounted in your desired location. Align the top clip of the switch with the top edge of the DIN rail, then push the bottom of the switch firmly until it clicks into place. To remove, pull down the bottom clip and lift the switch off the rail.
4.2 Connexió d'alimentació
Connect a DC power supply (18-32V) to the terminal block located on the side of the unit. Ensure correct polarity (V+ and V-). It is recommended to use a stable and regulated power supply suitable for industrial environments. Secure the wires firmly within the terminal block.
4.3 Connexió de xarxa
Connect your Ethernet devices (e.g., industrial PCs, PLCs, sensors) to any of the five 10/100Mbps RJ45 ports (P1-P5) on the front panel using standard Ethernet cables. The switch supports auto-negotiation and auto-MDI/MDIX, so straight-through or crossover cables can be used interchangeably.
5. Funcionament
5.1 Encès
Once the power supply is connected, the switch will power on automatically. The 'P' (Power) LED on the front panel will illuminate green, indicating that the device is receiving power and operating correctly.
5.2 Indicadors LED
- LED P (Engegada):
- Green: Device is powered on and functioning normally.
- Off: Device is not powered or there is a power issue.
- Alm (Alarm) LED:
- Red: An alarm condition is detected (e.g., link failure on a monitored port).
- Off: No alarm condition.
- Port LEDs (P1-P5):
- Green (Solid): A valid network link is established on the port.
- Green (Blinking): Data activity is occurring on the port.
- Off: No link detected on the port.
5.3 DIP Switch Configuration for Alarm
The DIP switches (1-5) on the side panel correspond to Ethernet ports P1-P5. By setting a DIP switch to the 'ON' position, you enable the alarm function for the corresponding port. If the link on an 'ON' configured port fails, the 'Alm' LED will illuminate red, and the alarm relay will activate. Set the DIP switch to 'OFF' to disable the alarm for that port.
6. Manteniment
The JetNet 2005 is designed for minimal maintenance. However, regular checks can help ensure optimal performance:
- Neteja: Netegeu periòdicament l'exterior del dispositiu amb un drap suau i sec. No utilitzeu netejadors líquids ni en aerosol.
- Ventilació: Ensure that the device's heat sinks are not obstructed to allow for proper heat dissipation.
- Integritat del cable: Inspect network and power cables for any signs of damage or loose connections.
- Condicions ambientals: Verifiqueu que l'entorn operatiu es mantingui dins dels rangs de temperatura i humitat especificats.
7. Solució De Problemes
- No Power (P LED Off):
- Check the power supply connection to the device.
- Verify the power source is active and providing the correct DC18-32V voltage.
- Assegureu-vos que la font d'alimentació funcioni correctament.
- No Link on Port (Port LED Off):
- Assegureu-vos que el cable Ethernet estigui connectat correctament pels dos extrems.
- Verify the connected device (e.g., PC, router) is powered on and functioning.
- Try a different Ethernet cable or port.
- Alm LED is Red:
- Check the link status of all ports that have their corresponding DIP switch set to 'ON'.
- A red 'Alm' LED indicates a link failure on one of the monitored ports.
- Address the link issue on the affected port.
- Rendiment de xarxa lent:
- Ensure all connected devices are operating at 10/100Mbps.
- Check for excessive network traffic or loops (though this is an unmanaged switch, loops can still cause issues).
- Inspect cables for damage or excessive length.
