Yealink Forums

Hello,
i've got 12 brand new SIP-T46U from my Distributor,
i preconfgured them to the new Auerswald Commtrexx Business PBX.

After a reboot of the hole System (Cisco CBS250-48PP, PBX, all Phones) one Phone will not boot.
Only a RED LED Light on the MWI lights up, no display backlight, no sound - nothing.

All Phones are powered over PoE+, all the other phones doesnt show this error.

I think something in Boot process failed? Could i fix this? Or should i send this phone back?

I checked to press the + - Button to bring up a sound or longer press X to reboot the phone, without success.

Thanks,
Martin

This is something that happens from time to time with Yealink phones and it means that phones or gone.

Just send it back and get a replacement.
