Hardware Installation Guide for the Polycom SoundStructure C16, C12, C8 and SR12
1 - 6
General Site Requirements
Please ensure the SoundStructure side ventilation holes have at least 1 inch of 
clearance from the sides of the rack to allow airflow through the device. 
Failure to maintain clearance for airflow may increase the operating 
temperature of the unit beyond its maximum operating temperature of 40° C 
(104° F).
With the proper side clearance, each SoundStructure device requires one rack 
space and does not require additional empty rack spaces above or below the 
device. When mounting with other equipment give consideration to having 
access to the audio connectors on the rear-panel.
When using SoundStructure with Polycom HDX video codecs, it is 
recommended that the SoundStructure devices be installed above the video 
codec.
If you are placing the device on a tabletop or other flat surface (rather than 
rack- mounting it), it is recommended to mount the adhesive rubber feet on the 
bottom of the device as shown in Rack-Mounting The Polycom 
SoundStructure Device to prevent damaging the finish of the furniture 
surface.
