I have:
- a new Cisco IP Phone 7942 after hard reset
- a new firmware version 9.4(2)SR3 for my phone (download from Cisco support center, login in need)
- a free TFTP server based on tftpd64.exe (http://tftpd32.jounin.net/tftpd32_download.html)
- a Fortigate FD100 device as DHCP server
And I need upgrade firmware. When IP Phone is booting he request IP address and address of TFTP server when is firmware placed.
1. First step - run the tftpd64.exe and set Current Directory with unpacked firmware (see folder contains below). And set interface for service listening.
This can you add via web interface. If I add pre configured option on FD, this dont work and I great a manual option with number 150 and add a HEX IP address of my TFTP server. HEX calculating using - http://ncalculators.com/digital-computation/ip-address-hex-decimal-binary.htm
3. Boot IP Phone and wait...
If you configured all fine the phone get IP address and start the process of upgrade:
Troubleshoting.
The biggest problem is optin 150. If you add this option correctly ont the side of TFTP Server you can see traffic from phone and can check error... See below:
This indicates that option set correctly byt need check the folder and files of firmware
