INSTALLATION PROCEDURE
2. PRECAUTIONS BEFORE BEGINNING INSTALLATION
2.1 Outline
1. Before beginning the installation, check to see if the installation requirements (grounding, the quantity and
kind of installation cables, etc.) are all present by referring to Chapter 2 of this manual.
2. For a standard installation, the system is installed on a free-access floor, so no explanations are provided
pertaining to cable racks and cable ducts.
3. The PBX is connected to the MDF by use of 25-pair shielded cables as the installation cables. Each of these
installation cables is grounded at the cable support assembly of the BASEU as shown below. By this ar-
rangement, noise radiation from each cable is prevented. For the installation method, refer to NAP-200-
013: “Cable Running from the Module Group to MDF, MAT, and SMDR.”
