Static Ip Addresses - Polycom SoundStructure C16 Design Manual

Assuming the computer that is running SoundStructure Studio also does not have an IP address provided
by a DHCP server, the local computer will also have a link-local address of the form 169.254.abc.def. The
computer may be connected either directly to the SoundStructure device or connected through a network
to the SoundStructure device, and then SoundStructure Studio will be able to automatically discover and
connect to the SoundStructure device. When connected directly to the device, the local computer may use
either with a straight-through or cross-over Cat5 cable.
The following figure shows how the SoundStructure device gets its IP address. If there is a static IP address
assigned to SoundStructure, then that address will be used. If there is a DHCP server, then the SoundStruc-
ture device will use the address provided by the DHCP server. If there is no DHCP server, then the
SoundStructure device will use a locally generated link-local IP address which will default to 169.254.1.1
assuming this does not create a conflict with a different device on the network.
Please note that when the SoundStructure device has a link-local IP address, if a DHCP server comes
online at a later time, the SoundStructure device will accept an IP address provided by the DHCP server
and will no longer have the link-local IP address.

Static IP Addresses

SoundStructure devices may also be assigned a static IP address directly from SoundStructure Studio or
manually via the API and a terminal session.
