Icim Introduction - Cisco Prisma II Installation And Operation Manual

ICIM Introduction

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)
software. The ICIM allows local module configuration and status monitoring for up
to 82 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
I.D. number.
