Chapter 6. 8260 Intelligent Cooling Subsystem
This chapter provides you with information about the 8260 intelligent cooling
subsystem.
6.1 Intelligent Cooling Subsystem
The 8260 intelligent cooling subsystem is made up of a number of different
components:
•
The fans and sensors
•
The DMM (Distributed Management Module)
•
The Controller module
•
The SCI (Serial Control Interface)
All of these components work together to make up the intelligent cooling
subsystem.
Each 8260 has three fan units that can be installed or removed while the 8260
hub is operating. These fan units are accessible from the back of the 8260 as
