# 7911 - 7906 Series :
|
|
|
|
## Intro :
|
|
|
|
You will need an IPv4 Network with :
|
|
|
|
* DHCP server (tested on tagged Voice-Vlan)
|
|
* TFTP server (option 66 configured in DHCP server)
|
|
* physical access to the phone
|
|
|
|
## Factory reset sequence :
|
|
|
|
When the phone start's up, (either POE or local adapter), dial the `#` until the red headset light starts blinking.
|
|
Dial `1 2 3 4 5 6 7 8 9 * 0 #` in that order. The phone will factory reset
|
|
|
|
## Flashing process :
|
|
|
|
```<loadInformation>``` is what needs to contain the firmware number.
|
|
|
|
After factory reset, the phone will look up in the TFTP server for his own config file (`SEP<mac-address>.cnf.xml`)
|
|
In the case of flashing to SIP firmware, that file has to contain the fact that it goes to SIP and a firmware version.
|
|
All system files must be stored at the root of the TFTP server.
|
|
|
|
## Startup Sequence :
|
|
|
|
At every reboot, the phone will look up for the ``SEP<mac-address>.cnf.xml``.
|
|
|
|
## Common problems:
|
|
|
|
Phone can start to boot-loop after flashing. Apparently, if it can't connect to the IPPBX, it will reboot. |
