OVERVIEW OF INSTALLATION, PROGRAMMING, AND MAINTENANCE
Installation of Main Equipment
The installation of the NEAX 2000 IPS is comprised of up to 8 Port Interface Modules (PIMs). A PIM provides
13 card slot for Common Control, Line/Trunk (LT), and Application Porcessors (AP) cards. It also houses an
AC/DC Power Supply, DC/DC Power Supply (for -48V), and batteries for protection from short-term (about 30
minutes) power interruption.
Cabling inside the unit, between the switching equipment and the MDF, can all be done by plug-and-jack
connections, while printed circuit cards can easily be plugged into the edge connectors. On all installations, a
special provision for plug-and-jack connections completely eliminates possible errors in wiring. This allows the
installation to be done easily and smoothly.
Mounting Circuit Cards
(1) Before mounting the circuit cards, confirm the following items.
Wrist Strap is connected to Frame Ground.
Switch settings of circuit cards are already completed.
The “SW1” switches of all PZ-PW121/PZ-PW126 cards are turned off.
(2) Mount circuit cards into their mounting positions according to the “Bay Face Layout” and “Port Assignment
Table” given in the Office Data Programming Manual.
Various installation Methods
To meet the specific needs of the customer's environment, NEAX 2000 IPS provides the following installation
methods:
Floor Standing Installation

Programming
System Initialization
There are two methods for System Initialization. The first method is to clear All Data, except LEN000 as a CAT
terminal, then program the System Data. The second method is to use the Resident System Program, which
causes the system to configure itself automatically to the default settings, wherever the line/trunk cards are
installed.
