Welcome to the Enterasys Systems NetSight Element Manager for the IRM2 User’s Guide. We have designed this guide to serve as a simple reference for using NetSight Element Manager for the IRM2.

The IRM2 is an IEEE 802.3-compliant repeater module designed to be installed in a Cabletron Systems Multi Media Access Center (MMAC®) hub, either with or without the Flexible Network Bus (FNB™). The IRM2 occupies the first (management) slot of the MMAC hub, and controls non-intelligent Ethernet modules installed to its left. It retimes and regenerates Ethernet data packets throughout the chassis, and performs automated management such as port segmentation. With NetSight Element Manager, you can gather a full array of statistical information from the IRM2 at the device, board, and port levels — including data throughput statistics and error breakdowns. You can also set alarms and traps for the hub, configure redundant circuits, or set port security parameters based on Ethernet source address locking.
