NWA210AX Console Port

Pook

Hi All

I have AP that went down today and I want to see if the appliance is accessible via CLI. I have the USB TTL cable but I cannot find any reference material regarding the Pin Out. Can anyone help?

There is a triangle under 1 pin which I assume to be pin 1?

Hi @Pook ,

In case your USB TTL cable is the cable with four pins including one pin with a triangle icon, please connect the USB TTL cable to NWA201AX by console cable’s pin with a triangle in the place of the NWA210AX console pin with a triangle icon (pin 1).

In case, your USB TTL cable is as below image, please follow Zyxel’s console header pin definition: pin1 NA (with the triangle mark), pin2 White (RX), pin3 Green (TX), pin4 Black (GND). PS: Don’t connect red color pin to zyxel’s console pin.

By the way, could you share with us the symptom when your AP went down?

Thanks Judy

We are observing the below…

1.Slow Blinking Amber/Green on status LED

2. Slow blinking Amber Ethernet port LED in Sync with Status LED.

3. Appliance not obtaining any IP address so not accessible via web console.

4. Several Device resets performed.

I got the terminal working now, I have the cable that has separate pins so thanks for the pin out. Can you give me any CLI commands that can be run? Appliance looks to be booting ok at least.

Hi @Pook ,

Please refer to this CLI reference, some console port notes are at the page 22.

By the way, we suggest checking the router's DHCP server settings to allow the AP to obtain an IP address.

Hi @Pook ,

The logs are normal when the AP is booting. Have you had any other issue with the AP?

Hi Judy

I am going to raise an RMA, the device just does not show on the LAN at all.

Hi @Pook ,

In you case, slow blinking amber/green on status LED means the AP not obtaining IP address actually.

You can try to use ZON to scan and set the static IP for AP. This link shows you how to configure Zyxel device basic setting.

And then, please access to the AP by the username/ password as admin/ 1234 to collect the diagnostic file. We'll support to check when receiving your file.

Or you also provide us the Teamviewer/ Any Desk remote session on the laptop that connects to the AP via console cable. We'd like to do troubleshooting.
