Scope and Introduction
The purpose of this information is to provide instructions on how to
install a SC 4812ET to SC 614/SC 614T (SC 614) companion frame
configuration. This procedure assumes that the SC 614 has been
previously installed, optimized, tested and is in operation.
This procedure details the steps necessary to convert the existing
SC 614T site from a starter frame to an expansion frame (see
Figure E-8). Interconnection ports are included in the SC 4812ET to SC
614 inter–cabinet cabling diagram (see Figure E-9).
