SECTION 2 - INSTALLATION

INSTALLING THE DX-120

Proper installation of the Vertical DX-120 is essential to assure optimum system operation. You must follow these
procedures to reduce system problems resulting from improper installation and to reduce the potential of
experiencing problems while bringing the DX-120 on-line.

Installation Overview

The following steps provide an overview of the installation process. Details on each of these steps are contained in
the following sections of this chapter. Be sure to read the detailed instructions before installing the DX-120.
A) Plan the installation, including the KSU1 or KSU1 and KSU2 and Main Distribution Frame (MDF) location,
station locations, cable runs, and optional equipment.
B) Assemble the correct tools and supplies: UTP telephony grade cable/wiring, miscellaneous telephony
hardware, 66 blocks, modular wall jacks, etc.)
C) Run the wiring for speakerphones, DSS consoles and analog devices (FAX machines, modems, etc.) from
the MDF to each location.
-
Wiring topology is referred to as "star-wiring" configuration; no cable should loop from one telephone
location to another.
D) Run cable/wiring to any optional equipment, such as external paging equipment, loud bell signaling devices,
music sources, etc.
E) Mount the MDF backboard and attach the terminal blocks on the backboard. Use a dedicated MDF with 66
block wiring field to promote full serviceability of the system and connections using proven techniques.
-
If you route extension cables into the KSU, you have to terminate one cable pair into standard crimping
modular connectors for each cable.
CAUTION
Although you can route the extension cable/wiring directly into the DX-120 KSU1/
KSU2 housing and connect directly to the appropriate interface module (408M,
DPM8, DPM16, APM4, COM4, CPM), Vertical does not recommend this method
since it makes it difficult to service the system.
F) Mount the KSUs on the MDF backboard, using the mounting template provided.
G) Ground the KSU1 (and KSU2 if applicable) to a known "good" earth ground.
H) Install optional expansion modules (COM4, DPM8, DPM16, APM4) inside the KSU as required.
I) Install optional features modules (AAM, 7270C, 7271C, or MDM) inside the KSU as required.
J) Install the telephone instruments and any optional telephone equipment, such as headsets or single line
telephones.
