- Эрчим хүчгүй:
Шинж тэмдэг: Цахилгаан LED унтраалттай байна.
Шийдэл: Цахилгааны залгуурыг унтраалга болон цахилгааны залгуурт холбосон эсэхийг шалгана уу. Залгуур ажиллаж байгаа эсэхийг шалгана уу. - Сүлжээний холболт байхгүй:
Шинж тэмдэг: Devices connected to the switch cannot access the network.
Шийдэл: Verify that Ethernet cables are securely connected to both the switch and the devices. Check port status LEDs; a solid green or blinking green indicates a link. Ensure the switch has a valid IP configuration and is connected to your router/gateway. - PoE төхөөрөмж асахгүй байна:
Шинж тэмдэг: PoE-powered device (e.g., IP phone) does not receive power.
Шийдэл: Ensure the device is PoE-compatible. Check the switch's PoE status LEDs for the specific port. Verify PoE settings in the switch's management interface. Ensure the total PoE budget of the switch is not exceeded. - Нэвтрэх боломжгүй Web GUI:
Шинж тэмдэг: Browser cannot reach the switch's IP address.
Шийдэл: Verify your computer's IP address is in the same subnet as the switch. Ping the switch's IP address to confirm network reachability. Clear browser cache or try a different browser.
