Important:
An IP deskphone cannot function without an IP address. The failure of a DHCP 
server at boot time leaves all the affected deskphones unusable. A user can 
manually assign an IP address to an IP deskphone. When the DHCP server 
finally returns, the deskphone never looks for a DHCP server unless the static IP 
data is unassigned manually. In addition, manual entry of IP data is an 
error-prone process. 
Avaya recommends that:
A minimum of two DHCP servers be available for reliability.
A DHCP server be available when the IP deskphone reboots.
A DHCP server be available at remote sites if WAN failures isolate IP deskphones from the 
central site DHCP server(s).
A (HTTP or HTTPS) file server, which may run on the same physical computer as Avaya Aura 
Communication Manager, provides the 1603SW-I SIP IP Deskphone with a 16xxupgrade.txt file 
and, if appropriate, new or updated binary software. See 
page 18. In addition, you can edit the settings file (46xxupgrade.txt) to customize deskphone 
parameters for your specific environment. For more information, see

Before you start, understand your current network configuration. An improper 
installation will cause network failures or reduce the reliability and performance of 
your network.
Configuring DHCP for 1603SW-I SIP IP Deskphones
1603SW-I SIP IP Deskphones allow you to specify the value of some configuration parameters 
using DHCP option 242. If you have 46xx phones that use option 176, you can make a copy of 
an existing option 176. Then, using that copy to administer DHCP option 242, you can either:
leave any (46xx) parameters the 1603SW-I SIP IP Deskphones do not support in Option 
242 to be ignored, or 
delete unused or unsupported 1603SW-I SIP IP Deskphone parameters to shorten the 
DHCP message length.
