If you experience ethernet or fiber port issues on your network switch, please follow these troubleshooting steps to identify and resolve the problem.

Note: If you are using a managed switch, please reset the device to factory default settings before proceeding with the hardware checks.

Step-by-Step Troubleshooting Guide

• Check the LED Indicator: Connect a device to the problematic port. Does the LED link light up or flash?
  
  
• Test Cables and Alternates: Replace the current network cable with a known working one. If the issue persists, try connecting the cable to a different port on the switch.
  
  
• Verify Fiber Port Specifications: If you are using fiber ports (SFP/SFP+), ensure that the transceivers and fiber specifications match on both sides (e.g., speed, wavelength, and fiber type).

───────────────────────────────

When choosing the right SFP transceiver modules for your network devices, ensuring compatibility on both ends of the fiber link is essential.

Please verify and match the following 4 key specifications for a successful connection:

1. Fiber Mode: Both ends must use the same fiber type, either Single-mode (SM) or Multi-mode (MM).
   
   
2. Data Rate / Speed: Ensure the transmission speed matches on both sides (e.g., 100Mbps, 1Gbps, or 10Gbps).
   
   
3. Wavelength & Transmission Distance: The wavelength (e.g., 850nm, 1310nm, 1550nm) and supported distance must be identical on both transceivers.
   
   
4. Connector Type: Check the physical fiber patch cord connector type required for your installation, such as LC, SC, ST, or BiDi (WDM) types like WA & WB.

Note: Always double-check your network switch's hardware datasheet to ensure it supports the specific data rate of the SFP module you select.

If you encounter issues during the firmware upgrade process, please refer to the "Troubleshooting Guides" included in our official Firmware Upgrade Instructions.

For a quick check, please ensure the following common issues are resolved:

• Stable Connection: Always use a wired Ethernet connection instead of Wi-Fi to perform the upgrade.

• Correct Firmware File: Double-check that the downloaded firmware version matches your specific product model exact hardware revision.

• Do Not Power Off: Never turn off or reboot the device while the firmware upgrade is in progress.

If the upgrade still fails, please check the detailed troubleshooting section within the instruction guide or contact Leonton's technical support team with your product model and current firmware version.

To ensure your IP camera, wireless access point, or other Powered Devices (PD) can receive power correctly, you need to check the PoE delivery mode compatibility.

Leonton network switches deliver Mode A (End-Span) PoE, which transmits both data and power over lines 1, 2, 3, and 6 of the Ethernet cable. Please verify your device's compatibility based on the following:

• Standard PoE Devices: Most modern PoE-compatible devices (IEEE 802.3af/at/bt compliant) are designed to support both Mode A (End-Span) and Mode B (Mid-Span) automatically. These devices will work perfectly with Leonton switches.

• Alternative/Legacy Devices: If your device strictly requires Mode B (Mid-Span) only, the PoE function will not work. Please check your device’s datasheet to confirm it supports Mode A or Alternative A input.

Based on our laboratory testing, more than 100 Leonton network switches can be utilized in a single ring topology while maintaining exceptional stability and network performance following ERPS recovery/convergence <50ms criteria.

The number of IP cameras supported in a 1G ring network topology depends entirely on the bandwidth requirement of each individual camera. Various camera settings, such as resolution, frame rate, and compression style, will directly determine the image size and required bandwidth.

Free online tool could help you calculate the total camera bandwidth size. Please note that a minor gap may exist between real-world applications and theoretical estimations.

To protect your network devices from voltage spikes and lightning, we highly recommend implementing the following hardware defense measures:

• Use a well-grounded and shielded cable to boost the overall surge immunity of the device.

• Install an additional surge protection device for the data port if the switch is located in harsh environments prone to high-voltage spikes.

• Position the surge protector as close as possible to the network switch to maximize its protection and avoid cable exposure between the devices.

To determine the total power budget required for your network project, you must combine the power consumption of the switch system itself with the total wattage of all connected powered devices.

Here is a practical calculation example using our PG2-1604-SFP switch and 5 PTZ cameras (with each camera requiring 10W):

Camera power consumption: 5 cameras × 10W = 50W

Switch system power consumption: 20W

Total power consumption: 20W (system) + 50W (camera) = 70W

Selection guide: Choose a 48V power supply with a capacity greater than 70W.

The compatibility of redundancy protocols between different firmware versions depends on whether you are using ERPS or RSTP.

• ERPS: It is not compatible between v2.x and v3.0 firmware.

• RSTP: It remains fully compatible between v2.x and v3.0 firmware.

No, we recommend using the included RS232 serial to RJ45 console cable to establish a stable console connection with your Leonton switch.

The original accessory features a DB-9 female connector on one end and an RJ-45 plug on the other. If you need to verify or customize a cable, please refer to the pinout diagram and mapping below:

• Pin 2 (DB-9F) connects to Pin 6 (8P8C)

• Pin 3 (DB-9F) connects to Pin 5 (8P8C)

• Pin 5 (DB-9F) connects to Pin 4 (8P8C)
