NEC ND-91649 Overview Of Installation, Programming, And Maintenance, Mounting Circuit Cards

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

Wall-mounting Installation

IEC standard 19-inch Rack-mounting 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.
