and/or a blinking cursor is
displayed after the firmware is
loaded.
There are two possible reasons for this type of error:
• The system is down.
• An incorrect MAC address is entered in DB Programming for the phone.
A phone entered into DB Programming with an incorrect MAC address
will still appear to download the initial configuration files; however, the
display error message indicates that the phone is not configured in the
system.
