Cisco Prisma II - ICIM Block Diagram

Chapter 3 Operation using ICIM
42 78-4015908-01 Rev F
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.
