 Setting up Your System

3 - 5

For downloading the bootROM and application images to the phone, the 
secure HTTPS protocol is not available. To guarantee software integrity, the 
bootROM will only download cryptographically signed bootROM or 
application images. For HTTPS, widely recognized certificate authorities are 
trusted by the phone and custom certificates can be added (refer to 

).

You can access the network configuration menu:

• During bootROM Phase. The network configuration menu is accessible 

during the auto-boot countdown of the bootROM phase of operation. 
Press the Setup soft key to launch the main menu.

• During Application Phase. The network configuration menu is accessible 

from the phone’s main menu. Select Menu>Settings>Advanced>Admin 
Settings>Network Configuration. Advanced Settings are locked by 
default. Enter the administrator password to unlock. The factory default 
password is 456.

Phone network configuration parameters may be modified by means of:

Use the soft keys, the arrow keys, the Select and Delete keys to make changes.
Certain parameters are read-only due to the value of other parameters. For 
example, if the DHCP Client parameter is enabled, the Phone IP Addr and 
Subnet Mask parameters are dimmed or not visible since these are guaranteed 

to be supplied by the DHCP server (mandatory DHCP parameters) and the 
statically assigned IP address and subnet mask will never be used in this 

configuration.

The basic network configuration referred to in the following sections can be 

reset to factory defaults using a multiple key combination described in 

.

Setting Option 66 to tftp://192.168.9.10 has the effect of forcing a TFTP download. 

Using a TFTP URL (for example, tftp://provserver.polycom.com) has the same 

effect.
