Description When configured for the network core, the CoreBuilder 9000 8-slot chassis provides unparalleled features and performance. The 8-slot chassis allows network designers to implement high-availability features such as redundant switching engines and management systems as well as redundant power and environmental subsystems.The 8-slot chassis consists of 6 payload slots for a total of 54 Gigabit Ethernet Layer 2 ports or 24 Gigabit Ethernet multilayer ports, with a backplane capacity of up to 240 Gbps. These features make the CoreBuilder 9000 8-slot chassis an ideal choice for the smaller data centers and network cores. The CoreBuilder 9000 8-slot chassis shares the same software, modules, and management systems as the 7-slot and 16-slot chassis. By deploying a common platform across the enterprise, network managers can significantly reduce staff training time and improve their overall operational efficiency. Sharing common modules among the chassis allows network managers to reconfigure and redeploy chassis and components across the network more easily, as well as to reduce their spares inventory.
