Nortel Ethernet Routing Switch 8600 or ERS 8600 (previously named Passport 8600) is a modular chassis combination hardware router and switch; in computer networking designed and manufactured by Nortel.
Configurable as a 1.440 Terabit Switch cluster using SMLT and RSMT protocols,[3] cluster failover (normally less than 100 millisecond).[4]
The ERS 8600 has 3 chassis options
8003, 3-slot chassis used for access or distribution / aggregation of switchs
8006, 6-slot chassis for backbones of low density or high space premium
8010, 10-slot chassis for high availability and high scalability
The chassis can be configured with one or two CPU modules (older modules 8691SF) (newer 8692SF modules), and is normally configured with two or three load balancing power supplies.
