Avaya Ethernet Routing Switch 8800 Series or ERS 8800, is a range of modular chassis products that combine hardware router and switch used in computer networking, designed and manufactured by Avaya. When an ERS 8000 Chassis, a passive device in its own right, is equipped with the 8895 SF/CPU, this system is known as an Ethernet Routing Switch 8800; conversely, when equipped with an 8692 SF/CPU module (with SuperMezz) the system is known as an Ethernet Routing Switch 8600.
