The PTN 950 is available in two models: common chassis and extended chassis, which are 2 U and 3 U 
high, respectively. Installation modes of the two types of chassis are basically the same; therefore, the 
common chassis is used as an example to describe the installation of the PTN 950 in this document. For 
information about the installation of the extended chassis, refer to the Appendix.
