Abstract

Avaya commissioned Tolly to evaluate a converged network infrastructure for enterprise users utilizing a wide array of Avaya switches, routers and IP phones to determine the energy usage at critical areas of deployment and to project the energy costs of operating the equipment over a five-year span.

Tolly engineers compared the energy consumption of the Avaya products, in terms of the power to operate the devices, as well as the power consumed in relation to heat dissipation. Results were compared with products from Cisco Systems, Inc.

Tolly engineers measured the energy usage (in terms of watts) for switch operation and heat dissipation for switches deployed in large- and medium-sized enterprise networks, in mid-sized companies, and enterprise branch offices. Engineers also tested IP phone endpoints from both companies.

Tests were conducted in May 2008.
