Juniper M320 AC Base Unit – includes Control Board, 4 Switch Interconnect Boards, 1 Routing engine, and 4 AC Power Entry Modules *SEE NOTES The M320 is a high performance, 10Gbps-capable, distributed architecture edge router. The M320 platform is ideal for medium-sized backbone cores requiring predictable performance for feature-rich infrastructures and also supports provider edge services in 10-gigabit POPs with the ability to support up to 32 type 1 and type 2 PICs and up to 16 type 3 PICs for 10 Gbps uplinks. In addition, this platform is ideal where switching fabric and Routing Engine redundancy are required. All major components are field replaceable, increasing system serviceability and reliability, and decreasing mean time to repair.This M320 AC Base Unit includes Control Board, 4 Switch Interconnect Boards, Routing engine with 1600MHz processor and 2GB memory, 128 MB external compact flash for routing engine, and 4 AC Power Entry Modules.
