How to fix signal loss in the fibre optic cable on MST Impact NS5004 Switch?
If you're experiencing signal loss in the fibre optic cable of your MST Switch, it might be due to a dirty composite connector or fibre port. Inspect the connectors and fibre ports to ensure they are clean. Use alcohol wipes or fibre optic cleaning kits to clean them. Avoid using air spray, as the compressor oil can leave residue.
What to do if WDS link fails to establish on MST Impact NS5004?
If the WDS link on your MST Switch isn't establishing, the MAC address might be incorrect. Verify the MAC addresses configured on the NS50 using the web browser interface.
Why is the power light on my MST NS50 blinking dimly?
If the power light on your MST NS50 is blinking on and off and appears dimly lit, it indicates that the NS50 isn't getting enough power. To fix this, you'll need an additional DC power supply to boost the power to the network switch. It's recommended to conduct a site survey to determine the power requirements during system design or modifications.
How to resolve power supply instability on MST Impact NS5004 Switch?
If you're experiencing power supply instability with your MST Switch, it could be due to a couple of things: * Incorrect earthing scheme: Check that antennas are insulated from ground and that the PCB in the network switch has a floating earth (not grounded). * Too many network devices on one power supply: Add additional power supplies or isolate network segments to prevent overload in case of a power supply failure.
What to do if LEDs on MST wireless network switch are not on?
If the LEDs on your MST wireless network switch aren't lighting up, it probably means the NS50 isn't getting any power. To resolve this: * Check that power is connected from either the composite cable or the test / configuration jig to the NS50. * Make sure the network switch is connected to a working power supply. * Test that the power supply is providing the correct voltage/current for the NS50. * If you've extended the NS50 infrastructure, ensure there's enough power available.
How to fix internet or LAN access issues with a wireless-capable PC on MST Impact NS5004?
If you're having trouble accessing the Internet or LAN with a wireless PC connected to the MST Switch, there are a few things to check: * First, reboot your computer. The wireless adapter may not have the correct TCP/IP settings to communicate with the network. * Ensure the port on the NS50 is enabled by checking the port activity light. If it's off, connect a PC to the network switch, access the web browser interface, and check the port is enabled in the Basic > Switch screen. * Also, verify that VLANs on the port are properly configured. Connect a PC to another port on the network switch to access the network and check that VLAN membership is assigned to the port for Internet / LAN access in the web browser interface.
