PRU Status LED (Bottom of PRU)
The PRU has a single red Status LED that is located on the bottom of the chassis.
At system startup, the PRU Status LED is red to indicate that the PRU is powering
up and that the SeRF processor does not yet control the PRU.
After start up, if the PRU Status LED is red, it indicates the presence of major
alarm(s) on the PRU. The PRU Status LED stays red until all the major alarm
conditions that exist on the PRU clear. (For information on alarms that pertain to
the PRU, see
“Troubleshooting Alarms” on page 185.)
