1-11 OverviewIntroductionMSR 50 Series Routers were self-developed by our company. for use on enterprise-level networks.Depending on the network size, MSR 50 Series Routers can be either core routers on small andmedium enterprise networks, or access routers for network branches on some large-sized enterprisenetworks. Therefore, MSR 50 Series Routers are suitable for the application on the carrier-levelnetworks, such as telecom management networks and billing networks. MSR 50 Series Routers adoptmodular design and support a wide range of optional interface cards and service modules, includingflexible interface card (FIC), smart interface card (SIC), multi-service card A (MSCA), enhanced servicemodule (ESM), voice processing module (VPM) and voice co-processing module (VCPM). Base onpower supply mode, the MSR 50-40 and MSR 50-60 each have two models: AC, DC.You can choose to use a DC or AC power supply unit (PSU) as the system power supply, or install twoAC or two DC PSUs to form 1+1 redundancy backup.The PSUs, fan trays, and FICs of MSR 50 series routers are all hot swappable.Currently, the MSR 50 series include these models:z MSR 50-40z MSR 50-60Fixed InterfaceTable 1-1 MSR 50-40/50-60 Routers interface descriptionItem MSR 50-40 MSR 50-60Console 1 1AUX 1 1USB 2 2GE 2 COMBO interfaces 2 COMBO interfacesFixedinterfacesFE switching interface 0 0Interface CardTable 1-2 MSR 50-40/50-60 Routers interface card descriptionItem MSR 50-40 MSR 50-60SIC module 4 4FIC module 4 6ExternalmodulesMSCA module 1 1
