Installing the Digital Telephone IP Adapter unit 
Powering up the Digital Telephone External IP Adapter unit
As soon as you connect the Digital Telephone External IP Adapter unit to the 
power source, the unit begins to power up. 
During power-up, the Digital Telephone External IP Adapter unit performs a 
self-test. The power LED flashes three times to verify all critical functionality, 
including:
!
RAM memory test
!
Flash checksum validation
If the Digital Telephone External IP Adapter unit completes a successful self-
test, the telephone display shows one of the following messages:
!
A time and date, if connected to a PBX.
!
HOSTLESS MODE
, if not connected to a PBX.
Note: The ETHERNET TX and RX LEDs flash only in response to transmit and 
receive activity.
