H3C MSR 20 Series Routers were self-developed by Hangzhou H3C Technologies
Co., Ltd. for use on enterprise-level networks. Depending on the network size,
MSR 20 Series Routers can be either core routers on small and medium enterprise
networks, or access routers for network branches on some large-sized enterprise
networks. Therefore, MSR 20 Series Routers are suitable for the application on the
carrier-level networks, such as telecom management networks and billing
networks. MSR 20 Series Routers adopt modular design and provide a wide range
of optional smart interface cards (SICs). The MSR-20, MSR 20-21 and MSR 20-40
are available with AC-powered units.
Currently, the H3C MSR 20 series includes the following models:
MSR 20-20
■
MSR 20-21
■
MSR 20-40
■
The H3C MSR 20 Series Routers include MSR 20-20, MSR 20-21, and MSR 20-40.
These three models are similar in chassis structure and layout. All of them can be
put on the tabletop and can be mounted in 19-inch standard racks. The following
subsections will give you more details about these three models.
