ICIM Introduction

Laser Warning

WARNING:

Avoid damage to your eyes! Do not look into any optical connector while the

system is active. Even if the unit is off, there may still be hazardous optical

levels present.

ICIM Function

The ICIM functions as the module-user interface as well as the interface between the

Prisma II modules and the Transmission Networks Control Systems (TNCS). The

ICIM allows local module configuration and status monitoring for up to 140

modules located in multiple chassis. The ICIM features easy-to-use software that is

navigated using the numeric keypad and the LCD display.
Important: Do not operate any Prisma II Chassis without a fan tray installed

properly. If a fan tray is not installed in the Prisma II Chassis, the ICIM will not

communicate with any of the modules in that chassis.
Important: All chassis connected in a “daisy-chain” must be powered and have a fan

tray installed. A chassis that is connected but is either not powered, or does not have

a fan tray installed will cause faulty operation of the ICIM.
Important: All chassis connected in this “daisy-chain” must have a unique chassis

identification (I.D.) number.
