WBE660S is launching but is not booting (not getting IP address)

root

Hi All,

I have the issue with WBE660S:

• it is not booting (no IP assigned)
• led is green
• uplink leds are keeping lighting (orange and green)
• reset button is not working (device is not restarting)
• doesnt matter if power is over USBC or POE via POE++ switch device.
• power consumption on the switch side is showing just around 6W

Hi @root,

We understand you're experiencing issues with your WBE660S not booting and not acquiring an IP address, despite a green LED and uplink LEDs being lit.

Here's a step-by-step guide to troubleshoot:

1. Verify Power Supply: The WBE660S requires 45W for optimal performance. While it shows around 6W consumption, this is significantly lower than the required power.

   • If using USB Type-C, ensure the power adapter provides at least 15V/3A (45W). The device prioritizes USB-C power if both USB-C and PoE are connected.
   • If using PoE, ensure your switch or injector supports 802.3bt (PoE++) for full functionality. 802.3at (PoE+) provides partial functionality, and 802.3af (PoE) only powers the CPU with no antenna functionality. The displayed 6W consumption suggests insufficient power, possibly due to a non-PoE++ port or an inadequate USB-C adapter.

2. Check LED Status:

   • A solid green LED on the WBE660S typically indicates full power mode with wireless clients connected. However, given the other symptoms, this might indicate it's stuck in a pre-boot state or a low-power mode where only the CPU is operational.
   • Uplink LEDs (orange and green) lighting up can indicate network link activity, with green usually signifying a 2.5Gbps link and orange indicating 10/100/1000Mbps. If these are constant, it suggests a physical link, but not necessarily data flow or successful booting.

3. Attempt Factory Reset:

   • The reset button should restart the device. If it's not working, the device might not be booting far enough to register button presses or could be experiencing a deeper hardware issue.
   • To perform a factory reset, ensure the AP is powered on. Locate the reset button (often recessed, requiring a paperclip or slender pin). Press and hold the RESET button for more than 5 seconds until the power LED starts blinking.

4. Isolate and Connect Directly:

   • Disconnect the WBE660S from your network and connect it directly to a computer via Ethernet.
   • Manually configure your computer's Ethernet adapter with a static IP address in the 192.168.1.x range (e.g., 192.168.1.10) and a subnet mask of 255.255.255.0. The default IP for Zyxel APs can be 192.168.1.1. Try to ping the AP at its default IP and then access the web interface.

To further assist you, please provide the following information:

• Network Topology Diagram: A simple diagram showing how the WBE660S is connected to your network, including any switches, routers, and power sources.
• Power Adapter/PoE Injector Model: Specify the exact model of the USB-C power adapter or PoE switch/injector you are using.
• Firmware Version: If accessible, please provide the current firmware version of the WBE660S.
• Error Message Screenshot: Any error messages displayed if you can connect to the device.
• Nebula Information: If this WBE660S was previously managed by Nebula, please enable Zyxel Support Access via Help > Support Request in the Nebula control panel and provide your Organization and Site name. This will allow our team to directly view your cloud configuration and expedite troubleshooting.

Hi @root,

Welcome to the Zyxel Community!

To help us investigate further, please re-power the WBE660S, then confirm the status of:

• System LED – is it solid green?
• Uplink / Ethernet port LED – is it solidly orange and green?

This will help us to provide the more suitable next troubleshooting steps.
