EME Overview 33

CoreBuilder 9000	You can manage the CoreBuilder 9000 system through a terminal
Management	interface, through the Simple Network Management Protocol (SNMP),
Features	and through the 3Com Transcend® Network Control Services. The EME is
	the primary communication mechanism into the chassis and modules.
	You manage other intelligent modules within the chassis through the
	EME.
EME Overview	The EME is an SNMP-based network management module that manages
	and controls the 3Com CoreBuilder 9000 chassis and its modules. The
	EME has the following features:
	■ Chassis Management Architecture — Provides a cost-efficient
	management architecture that:
	■ Provides a central point of contact for chassis management
	■ Provides all controller functions, as well as EME functions
	■ Intelligent Power Management — Manages power use in the
	chassis by:
	■ Preventing newly installed modules from receiving power when
	there is not enough power available
	■ Allowing you to prioritize the order in which modules power off (if
	there is insufficient power available)
	■ Allowing you to implement fault-tolerant power, which allows the
	chassis to reserve some of its power capacity to protect against a
	power supply failure

In the chassis:

■The EME exchanges information with all modules through the MLAN.

■Interface modules pass data through the switch fabric module.

■On modules that include their own agent, the EME “connects” to that module and then you can use the Administration Console management interface to manage that module.
