5620 Screen blacked out and Keeps Rebooting on IP500? 1

[RickyBobby]

Hi,
We have a 5602 plugged in as an IP phone to display to customers in our office. I've been given 4 x 5620 phones to test. I've literally unplugged the 5602 and plugged the 5620 in and followed exactly the same settings. The phone will boot up and i can make and recieve calls fine but there is no display at all on the screen, it's just completely blacked out and also after about 15 seconds the handset reboots?

This happens with 3 of them. The 4th tells me that there is a DHCP conflict and will not go any further even though the settings are all the same?

Any help would be much appreciated.

Thanks,

RB

EDIT: I've just noticed. The phones are 5620SW but when I log onto the 500 it's telling me that they are 4620's? Wrong configuration file it's picking up by any chance?

What does monitor says ?

Go to status -> ipphone status

Did you upgrade the phone to 2_3 or higher ?

No it's sat at 2.100. How would I go about upgrading it to a higher level?

Thank you for your help

Set the working directory of manager to c\program files\avaya\ip office\manager

leave manager open and reboot the phone. set the file server of the phone to a pc running Manager.

Sorry guys I suffered brain failure today. I updated the phones and it works just fine. They were sat on 2.1 and so would only be recognized as the 4620. I'm not sure why I asked you how I would update the phones, I do it all the time :S Brain failure moment.

But thanks for your replies either way
