1 OVERVIEWIntroduction H3C MSR 30 Series Routers were self-developed by Hangzhou H3C TechnologiesCo., Ltd. for use on enterprise-level networks. Depending on the network size,MSR 30 Series Routers can be either core routers on small and medium enterprisenetworks, or access routers for network branches on some large-sized enterprisenetworks. Therefore, H3C MSR 30 Series Routers are suitable for the applicationon the carrier-level networks, such as telecom management networks and billingnetworks. MSR 30 Series Routers adopt modular design and support a wide rangeof optional smart interface cards (SICs) and multi-function interface modules(MIMs). Currently, the MSR 30-11 can adopt AC only, the MSR 30-16 can adoptAC and PoE, and the MSR 30-20, 30-40 and 30-60 can adopt AC, DC, and PoE.Except the MSR 30-11 and the AC-powered MSR 30-16, the MSR 30 series routerseach provide a redundancy power system (RPS) interface to enhance the routers’reliability. The PoE-powered routers can remotely supply power to its powereddevices (PDs).H3C MSR 30 series include these models:■ MSR 30-11■ MSR 30-16■ MSR 30-20■ MSR 30-40■ MSR 30-60System DescriptionFixed Interfaces Table 1 Fixed interfaces of the H3C MSR 30 series routersItem MSR 30-11 MSR 30-16 MSR 30-20 MSR 30-40 MSR 30-60FixedinterfacesConsole 1 1 1 1 1AUX 1 1 1 1 1USB 0 1 2 2 2FE 2 2 0 0 0GE 0 0 TwoelectricalinterfacesTwo CombointerfacesTwo CombointerfacesSA 1 0 0 0 0
