5. Setup Instructions
5.1. Mounting the Switch
The KP-9000-45-5TX is designed for DIN-rail mounting (DIN35mm). Attach the provided DIN-rail clip to the back of the switch and secure it onto a standard DIN rail in your industrial cabinet or enclosure.
5.2. Power Connection
The switch supports 12-58 VDC redundant power inputs (PWR1 and PWR2) via a 3-contact terminal block. Connect your DC power sources to the terminal block, ensuring correct polarity. The redundant inputs allow for continuous operation even if one power source fails.
5.3. Network Connection
Connect your Ethernet devices (e.g., PLCs, cameras, computers) to the RJ45 ports (1-5) using standard Ethernet cables. The switch supports MDI/MDI-X auto-sensing, so you don't need to worry about straight-through or crossover cables.
5.4. DIP Switch Configuration
The switch features DIP switches for advanced configuration:
- Broadcast Storm Protection: Enable or disable this feature to prevent network congestion caused by excessive broadcast traffic.
- Port Isolation: Enable or disable port isolation to restrict communication between specific ports, enhancing security and network segmentation.
Refer to the markings on the switch for the exact position and function of each DIP switch. Ensure power is disconnected before changing DIP switch settings.
6. Operating Instructions
6.1. Power On
Once the power supply is connected, the switch will automatically power on. The power indicator LEDs (P1, P2) will illuminate to indicate active power inputs.
6.2. Network Operation
The KP-9000-45-5TX is an unmanaged switch, meaning it operates automatically without requiring any software configuration. Simply connect your Ethernet devices to the RJ45 ports. The corresponding port LEDs will light up when a valid link is established and will flash to indicate data activity.
6.3. LED Indicators
- P1/P2 (Power): Indicates power status for redundant inputs. Lit when power is supplied.
- Port LEDs (1-5):
- Solid Green: A valid network link is established.
- Flashing Green: Data activity on the port.
- Off: No link or device connected.
7. Maintenance
7.1. Cleaning
To clean the switch, disconnect power and use a soft, dry cloth. Do not use liquid or aerosol cleaners. Ensure no dust accumulates in the ventilation fins of the housing.
7.2. Environmental Considerations
The switch is designed for industrial environments with an IP40 rating, protecting against solid objects larger than 1mm. While robust, avoid exposing it to direct water spray or prolonged high humidity. Ensure the operating temperature remains within -30°C to 75°C.
8. Troubleshooting
- No Power: Check power connections to the terminal block. Verify that the 12-58 VDC power supply is active and correctly wired. Check the P1/P2 LEDs.
- No Link on Port: Ensure the Ethernet cable is securely connected to both the switch and the connected device. Verify the connected device is powered on and functioning correctly. Try a different Ethernet cable or port.
- Network Performance Issues:
- If experiencing slow speeds or intermittent connectivity, check the DIP switch settings for Broadcast Storm Protection and Port Isolation. Incorrect settings might impact network traffic.
- Ensure cables are not damaged and are within the maximum recommended length for Ethernet (100 meters).
- Device Not Recognized: Ensure the connected device's network settings are correct (e.g., IP address, subnet mask).
