Generic Modules
The MSR 50 series is available with the generic modules as power modules, SICs and interface
modules. Currently, it primarily supports the main board MPUF. See details as follows.
MPUF
Functions
As the core of the router, the MPUF 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.
