Installing The SoundStructure C16, C12, C8, And SR12
2 - 7

Connecting To The LAN Interface

The SoundStructure device's Ethernet interface (as shown following figure) is
a 10/100 Mbps interface that supports Auto-MDIX (medium dependent
interface crossover).
Auto-MDIX enables the use of a standard CAT5e cable to connect directly
from the SoundStructure device to either an Ethernet network or to a
computer. The SoundStructure device will detect the connection and work
appropriately.
By default the SoundStructure device has Dynamic Host Configuration
Protocol (DHCP) enabled and will accept an IP address from a DHCP server.
The SoundStructure device IP address can also be set to a static IP address
using the SoundStructure Studio software.
Do not plug the Ethernet cable in to the Conference Link2 ports. To minimize
improper cabling, plastic plugs have been installed by default into the
Conference Link2 ports.

Connecting To Other Polycom Equipment With Conference Link2

The Conference Link2 interface (shown in the following drawing and labeled
C-Link2) is used to connect the SoundStructure devices to other Polycom
equipment such as a Polycom HDX system. There are two Conference Link2
interfaces on each SoundStructure device to support future connectivity to
more than one Polycom device. The Conference Link2 ports on the
SoundStructure devices have a plastic plug that must be removed before
inserting a cable into the Conference Link2 ports. The Conference Link2 ports
