Network does not recognize the webswitch and programing failed

[HL5BHH]

I purchased webswitch recently (v.4.23) but failed to link to network switch.  Network does not recognize the webswitch.
(green LED near USB is blinking)

I reinstalled same firmware, however , the result was 'failed programing new firmware:failed acknowledge from the device'
afterthen red LEDs of five relay switch turn on, still can not be recognized by network switch.

I tried to downgrade to v 4.20 with same phenomenon.
Red light near relay switch means something wrong?  and why the network switch can not recognize webswitch?

Hi

I guess your power supply cannot delivery power enough. If so the webswitch turn of the Ethernet interface and only the USB is working with power from the PC. Measure the voltage on the screew terminal. I recommend to use a 12V 1A Power supply

Thank you, Mike.   It works nice.
I used a small power supply (150ma)  for testing, so I changed to bigger power suppy for ham radio.
LED for Lan switch turns on and everyting is OK.
By the way, blinking of 5 red lights is normal?

Kind Regards

Do you mean that the 5 relay LEDs are blinking?

Yes, but it turns off after setting the relays off.
No problem now.
Thanks
