Table 8 describes the meaning of the system status LEDs after the system has been booted up and
is in service.
During BCM50 system startup or reboot, the system status LEDs move through a sequence of state
changes. In general, if either the power LED or status LED is yellow, the system is initializing and
is not ready for service. Table 9 shows the key states indicating service availability.
LAN port LEDs
Each LAN port on the main unit and expansion unit has two LEDs. These LEDs indicate the status
of the connection for that LAN port. Figure 21 on page 61 shows the location of these LEDs on the
BCM50 units.
