Overview
Introduction
MSR 50 Routers were self-developed by our company for use on enterprise-level networks. Depending on
the network size, MSR 50 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 50
Routers are suitable for the application on the carrier-level networks, such as telecom management
networks and billing networks. MSR 50 Routers adopt modular design and support a wide range of
optional interface cards and service modules, including flexible interface card (FIC), smart interface card
(SIC), multi-service card A (MSCA), multi-service card B (MSCB), enhanced service module (ESM), voice
processing module (VPM) and voice co-processing module (VCPM).
The MSR 50-40 routers are 3U in height and the MSR 50-60 are 4U in height. Slot 0 provided on the
front panel of both the two models is for the main control board, which can be MPUF or MPU-G2
respectively. MSCA or MSCB can be installed in the MSC slot provided on the backplane to provide a
variety of security and voice services, where MSCA works in conjunction with MPUF while MSCB works
with MPU-G2.
Base on power supply mode, the MSR 50-40 and MSR 50-60 each have three models: AC, DC, and PoE
power supply. You can choose to use a DC or AC power supply unit (PSU) as the system power supply,
or install two AC or two DC PSUs to form 1+1 redundancy backup. You can also install a PoE power
module to work in conjunction with the AC or DC PSU to provide remote power supply for powered
devices (PDs).
The PSUs, fan trays, and FICs of MSR 50 routers are all hot swappable.
Currently, the MSR 50 include these models:
• MSR 50-40
• MSR 50-60
