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

Use the following procedure:

NOTE: This procedure occurs with normal application file upgrades.

1. The following message displays:

2. While the hardware is being initialized, the following message displays:

3. While either the application file if there is one or the boot code is uncompressed into RAM, the following message displays:

This message counts the seconds as the application file (4620_031225.app in this example) is being written into RAM.

4. When control is passed to the code in RAM, the following message displays:

5. The telephone detects and displays the speed of the Ethernet interface in Mbps, that is, 0, 10, or 100. The message No Ethernet displays until the software determines whether the interface is 10 Mbps or 100 Mbps.

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

6. 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.

7. The following message displays while the TFTP or HTTP process is invoked:

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

8. The following message displays while the upgrade script is downloaded from the TFTP server:

where n is the number of KBs downloaded.

9. 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.

10. 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.

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