Static Ip Addresses - Polycom SoundStructure C16 Design Manual

Design Guide for the Polycom SoundStructure C16, C12, C8, and SR12

Static IP Addresses

10 - 4
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 SoundStructure 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 differ-
ent 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.
Use Link-Local address
(if that creates a conflict the system
SoundStructure devices may also be assigned a static IP address directly from
SoundStructure Studio or manually via the API and a terminal session.
