System status LEDs
The two system status LEDs on the BCM50 main units (BCM50, BCM50a, BCM50e, BCM50b,
BCM50ba, and BCM50be) show the current state of the BCM50 system.
You can view the system status LEDs on the faceplate and on the top of the main unit. See the
figure
Location of system status LEDs on a main unit on page 61. The bottom LED is the power
LED, and the top LED is the status LED. Under normal operating conditions, both LEDs are solid
green.
