4. Restart Scenarios
The sequence of the restart process depends on the version of the phone boot file already downloaded to the phone as
well as those on the file server. This appendix explains the different scenarios possible.
All of the following start-up procedures involve the same initial steps as the phone negotiates with the DHCP server and
the file server.
Restart scenario:
1. After power is applied, the phone displays Restarting... followed by Initializing....
2. When either the application file (if there is one) or the boot code is uncompressed into RAM, Loading is
displayed. Since this takes a while, asterisks, then periods, then asterisks are displayed on the second line to
indicate that something is happening.
3. When control is passed to the code in RAM, Starting is displayed.
4. The phone detects and displays the speed of the Ethernet interface in Mbps (that is 10 or 100). The message No
Ethernet means the LAN interface speed cannot be determined. The Ethernet speed indicated is the LAN interface
speed for both the phone and any attached PC.
5. DHCP is displayed whilst the phone obtains an IP address and other information from the LAN's DHCP server. The
number of elapsed seconds is incremented until DHCP successfully completes.
·
If the phone has been setup using static addressing (by pressing * when DHCP is shown), it will skip DHCP and
use the static address settings it was given.
·
Note that uploading a new boot file at any time erases all static address information.
6. 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.
7. After the upgrade script is loaded, the sequence depends on the status of the files currently held in the phone's
memory, compared to those listed in the upgrade script file.
