NOTE:
The figures above illustrate the components of a router with MPUF installed. No SIC slots are provided if
an MPU-G2 is applied on the router.
Generic Modules
The MSR 50 is available with generic modules such as SIC and FIC interface cards. For detailed
information about interface cards, refer to MSR Series Routers Interface Module Manual.
For the types of interface modules that each model of the MSR 50 routers can accommodate, refer to
Appendix A Interface Card and Interface Module Purchase Guide in the MSR Series Routers Interface
Module Manual.
Currently, the MSR 50 routers primarily support the main boards MPUF and MPU-G2. See details as
follows.
MPUF/MPU-G2
Functions
As the core of the router, the MPUF/MPU-G2 functions to process protocols, forward low-speed packets,
govern interfaces, and detect faults. You can gather information about the operating state of FAN module,
PSU, and system by reading their corresponding LEDs on the main control board; alternatively, you can
monitor state using a network management system. In addition, the main control board provides a
hardware reset button: RESET. Each MPUF provides four SIC slots for extending the access capabilities.
An MPU-G2 delivers improved process capabilities without offering any SIC slots.
