Latest Boot File Loaded/No Application File or
Application File Needs to be Upgraded

This procedure occurs with normal application file upgrades.

1. The telephone displays:

2. The telephone detects and displays the speed of the Ethernet interface in Mbps, that is, 10, 100, or 1000. The message No Ethernet displays until the software determines whether the interface is 10 Mbps, 100 Mbps, or 1000 Mbps.

NOTE: The Ethernet speed indicated is the LAN interface speed for both the telephone and any attached PC.

3. The software determines whether sufficient IP Address information was downloaded. In this scenario, it is discovered that sufficient information has not been downloaded. The following message displays while the DHCP process is invoked:

The number of elapsed seconds is incremented once per second, until DHCP successfully completes.

4. While the IP telephone establishes a TCP connection to the HTTP server, the telephone displays the following message:

where n is the number of the IP Address obtained from the HTTP server and ipadd is the IP Address.

5. The following message displays while the HTTP process is invoked:

The number increments once per second, until the HTTP server responds.

6. While the upgrade script file is being downloaded from the HTTP server, all IP telephones display the following message:

where n is the number of the IP Address obtained from the HTTP server, sc is the status code of the HTTP response and etag is the value of the ETag header.

7. The script file is processed. The software determines that the name of the boot code file in the telephone (BOOTNAME) is not the latest version. APPNAME is set to the name of an application file to replace the boot code. The following message displays while the application file is downloaded into RAM:

where n is the number of KBs downloaded.

8. When the telephone determines that the application file received is valid, the following message displays:

where s is the number of seconds that elapse while non-volatile memory is erased.

9. The following message displays while the application file is stored in flash memory:

where n is the percentage of the file that was stored, and x is the number of elapsed seconds. This usually takes longer than the file’s download.

10. The telephone is reset so the new system-specific application file can be executed.
11. Continue with the next procedure.
