We have an ES450 device that has been in the field for some time that suddenly locked up on us. It now shows All LEDs solid green. Nothing that we tried seems to take it out of this state. The LEDs will briefly show all 4 Red if the reset button is held in for 20+ seconds but as soon as the button is released the LEDs return to solid green. I reviewed the LED Behavior chart in the ES Hardware User guide r6, which I believe is the latest version, and there is no record for what All LEDs Solid Green means.

This device is running ALEOS 4.9.3.002 and has been out of warranty since 11/15/2021. Any assistance you can provide is appreciated.

Hi Matt.Pickney,

Could you try updating the ES450 to the latest firmware version 4.9.6.008 and retry?

I have 3 modems at customer site exhibiting this same behavior and am not even able to get to the Gateway Configuration page to attempt a FW upgrade. I have tried the 20 second factory reset attempt as well and no luck

Any advise would be greatly appreciated!

Hi @Engrforever  
Welcome you to our community  
According to the AirLink ES450 Hardware User Guide, to reset the ES450 Airlink to the factory default settings, please press and hold the Reset button until all the LEDs turn red (about 7–10 seconds).

For more details, You can refer to Section 2 - Startup and Configuration on page 25 in the link below:
