Chapter 2: Install the GF502 VOIP Phone
This section provides instructions for installing the GF502 VOIP Phone. Before you perform
the installation, be sure you have met the following prerequisites:
¾ Planned the network and GF502 VOIP Phone configuration.
¾ Installed and configured the other network devices.
¾ 10BASE-T or 100BASE-T or better Ethernet cable. One cable is needed for each
Ethernet connection.
1After you install a phone, even if it is new, upgrade the phone to the current firmware image.
For information about upgrading, refer to Chapter 4.
