Chapter 3 Operation using ICIM

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.
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.
All chassis connected in this daisy-chain must have a unique chassis
identification (ID) number.
The last chassis in the daisy-chain must have a terminator installed in the ICIM
OUT connector. Otherwise, faulty communication with the ICIM may occur.
