System Status LEDs
The R2MFC MBM has three visual status monitor indicators on the left side of the faceplate. They are:
•Power LED — This green LED indicates the status of power to the R2MFC MBM.
•In Service LED — This green LED indicates the status of the E1 signal coming to the R2MFC MBM from the BCM.
•Diag LED — This red LED indicates if the R2MFC MBM is in a diagnostic or loopback mode.
