2.6 Phone Connection
In this process the phone is connected to its power source and to the ethernet LAN. As soon as the phone is powered up
it will start to request information.
1. Do not start this process until all the preceding steps in the
Installation Summary
have been completed.
2. Connect the network LAN cable to the data-in socket of the power supply being used for the phone.
3. Connect the LAN cable supplied with the IP phone from the power supplies data and power out socket to the
socket with a LAN port symbol (
) at the back of the IP phone.
4. The phone's message indicator should glow red for a few seconds. The phone will then begin its software loading
process. After a short delay, the phone displays Initializing and then Loading…. The loading phase may take a
few minutes.
·
If the phone has an existing software boot file (ie. it has been previously installed), it will load that file and
then display Starting....
·
If the phone displays No Ethernet, check the connection to the LAN.
5. The phone displays DHCP and a timer as it attempts to request an IP address and other information from a DHCP
server.
·

Static Address Installation
.
6. After a few seconds, DHCP negotiation should be completed. If the timer reaches more than 60 seconds, it could
indicate an error in either the network or DHCP server configuration.
7. Once DHCP has completed successfully, the phone will request files from the file server indicated in the DHCP
response. The first file requested details the other files that the phone should also load. The phone will first make
its file request using HTTPS. If this fails it will make the same request using HTTP. If that fails it will make a final
request using TFTP. If all requests for a file fail, the phone will fallback to using the current version of the file it has
in its own memory.
8. The phone will go through a cycle of requesting files, loading files and then transferring the files into its flash
memory.
9. Following file loading, the phone displays Ext. =. See
Phone Registration
