Introduction
This guide compliments the Aastra
Model 480i CT Installation Guide that
is included with the phone. Please
refer to the installation guide for
information on hardware
requirements, features and physical
set up of your new 480i CT.
Software Prerequisites
• Permission to register at the IP PBX
• Access to a Trivial File Transfer
Protocol (TFTP) server
Methods of installation
The software set up and installation
for 480i CT can be through the user
interface available from the phone
itself or through the AASTRA 480i CT
WEB CLIENT web interface.
When the 480i CT is initialized for the
first time, DHCP is enabled by default.
The DHCP server passes information
to the IP phone so that it can configure
itself for subsequent IP PBX address
and normal runtime operations.
Note:
• If you are planning on using
Dynamic IP addresses, make sure a
DHCP server is running on your
network
• If you are not planning on using
Dynamic IP addresses, refer to sec-
tion 5,”Configuring the 480i CT IP
phone” on how to set up an IP
address manually
• Make sure a TFTP server is set up
on your network and can accept
connections anonymously
Warning: Do not reset or turn off the
phone while the phone is initializing or
downloading firmware.
