1-4CHAPTER 1: OVERVIEW

Switching Module	The two slots just under the power supply contain switching modules,
	one slot for the active switching module and one slot for the redundant
	switching module.
	The switching module is the core switching engine of the CoreBuilder
	7000 family ATM switch, controlling and monitoring passive backplane
	and ATM activity. The switching module has a control port for connection
	to a terminal, a management port for connection to a network
	management station, and a service port for use by 3Com technicians.
Interface Module	The next four slots contain interface modules. These can be of many
	different types; some are shown in the figure (see the CoreBuilder 7000
	Family ATM Switches User Guide for details).
Fans	For ventilation a fan tray with 6 fans is located at the left side of the unit.
