Faceplate LEDs

There are two sets of LEDs on the faceplate of the R2MFC MBM. The system status LEDs are made up of the Power LED, In Service LED, and Diag LED. Table 14 shows the LEDs and their states.

Table 14 System status monitor LEDs

			LED Status

LED Name	Green Solid	Green Flashing	Red Solid	Red Flashing	OFF

Power	Active Power	N/A	N/A	N/A	No Power

In-Service	Normal Operation	Start Up	N/A	N/A	Out-of-Service

Diag	N/A	N/A	Test Mode	N/A	Normal Operation

•As the BCM starts, the In Service LED is Green Flashing.

•Once powered up, the Power LED is set to Green, the In Service LED is set to green, and the Diag LED is off.

•When the MBM is operating properly, the In Service LED is Green Solid.

•During an alarm on the internal PRI link, the In Service LED is off.

•During test mode, the Diag LED is red.
