- Complies with IEEE802.3, IEEE802.3u Ethernet Standards. Offers 48 10/100Mbps Auto-Negotiation RJ45 ports.
- Supports Auto MDI/MDIX to simplify network setup and maintenance.
- Supports NWAY Auto-Negotiation function, automatically detecting transmission rate and duplex modes to choose the best network connectivity.
- Supports IEEE802.3x full-duplex flow control and half-duplex backpressure flow control.
2. What's in the Box
Please verify that all items are present in the package:
- Tenda TEH1048 48-port unmanaged 10/100 Mbps Ethernet switch
- User manual
- One power cord
- Two mounting ears
- Eight screws
- Four rubber feet
3. Setup Instructions
3.1 Unboxing and Placement
Carefully remove the switch and all accessories from the packaging. Place the switch on a stable, flat surface or mount it in a standard 19-inch equipment rack using the provided mounting ears and screws. Ensure adequate ventilation around the device to prevent overheating.
3.2 Connecting Power
- Connect one end of the provided power cord to the power inlet on the rear panel of the TEH1048 switch.
- Plug the other end of the power cord into a standard AC power outlet (100-240V AC, 50/60Hz).
- Verify that the Power LED on the front panel illuminates, indicating the switch is receiving power.
3.3 Connecting Network Devices
The TEH1048 is a Plug-and-Play device, requiring no software configuration for basic operation.
- Connect Ethernet cables from your network devices (e.g., computers, servers, network printers, routers) to any of the 48 RJ45 ports on the front panel of the switch.
- The switch's Auto MDI/MDIX feature automatically detects the cable type (straight-through or crossover), so you do not need to use specific cable types for different connections.
- Observe the Link/Act LEDs next to each port. A solid green LED indicates a successful network link, and a blinking LED indicates data activity.

4. Operating the Switch
The Tenda TEH1048 is an unmanaged switch, meaning it operates automatically without requiring user configuration. Once powered on and connected to network devices, it begins forwarding data.
4.1 Plug and Play Operation
The switch is designed for immediate use. Simply connect your devices, and the switch will automatically detect their speed (10Mbps or 100Mbps) and duplex mode (half or full) using NWAY Auto-Negotiation. It will then establish the optimal connection.
4.2 LED Indicators
- Power LED: Illuminates when the switch is powered on.
- Link/Act LEDs (per port):
- Solid Green: Indicates a successful network link.
- Blinking Green: Indicates data transmission or reception activity on the port.
- Off: No link detected or device is not connected.
5. Maintenance
To ensure optimal performance and longevity of your Tenda TEH1048 switch, follow these maintenance guidelines:
- Cleaning: Regularly clean the exterior of the switch with a soft, dry cloth. Do not use liquid or aerosol cleaners.
- Ventilation: Ensure that the ventilation openings are not blocked. Maintain adequate space around the switch for proper airflow.
- Environment: Operate the switch within its specified temperature and humidity ranges. Avoid exposing it to direct sunlight, excessive heat, or moisture.
- Cable Management: Keep network cables organized and free from kinks or excessive bending to prevent signal degradation.
6. Troubleshooting
If you encounter issues with your Tenda TEH1048 switch, refer to the following common troubleshooting steps:
- No Power:
- Check if the power cord is securely connected to both the switch and the power outlet.
- Verify that the power outlet is functional by plugging in another device.
- Ensure the Power LED on the switch is illuminated.
- No Link on a Port:
- Ensure the Ethernet cable is securely connected to both the switch port and the network device.
- Check the integrity of the Ethernet cable; try a different cable if necessary.
- Verify that the connected network device is powered on and functioning correctly.
- Confirm that the Link/Act LED for that port is solid green.
- Slow Network Connection:
- Ensure all connected devices are operating at their expected speeds.
- Check for excessive network traffic or bottlenecks upstream (e.g., router, internet connection).
- Verify that cables are not damaged or too long, which can affect performance.
- Intermittent Connectivity:
- Inspect all cable connections for looseness or damage.
- Ensure the switch is placed in a well-ventilated area to prevent overheating.
- Consider restarting the switch and connected devices.
