Using the System Controller

This chapter describes how to use the two system controller types in a rackmount system.
• multimodule System Controller (MMSC) and display
• module System Controller (MSC) and display
The MMSC in a rackmount system is an intelligent communcations device that can
monitor one or more system "modules" within a rack.
The MSC in a deskside system or a rackmounted system "module" is less sophisticated
than the MMSC. Each MSC in a rack reports to and can be controlled by the MMSC.
The MMSC subsystem is composed of two main components:
• the MMSC itself
• the front display and input panel
• 10BaseT Ethernet hub (only in systems with three or more racks)
