CPU Boot-Up Status LED
The CPU boot-up status LED is located just under the Compact Flash
(CF) card. It provides the status condition of the CPU board during and
after powering up (boot-up). See Figure 80. The following is a list of the
LED status conditions.
1 The LED is off while the operating system comes up and the R450
MC boot loader program runs.
2 The LED flashes twice per second while the main loader is running.
3 The LED flashes once per second while the main R450 MC
application is initializing.
4 The LED flashes once every 10 seconds once the main application
has initialized. At this time, it is safe to remove the USB flash drive
from the USB port. See “Configuring the R450 MC” on page 29.
5 The LED flashes 4 times per second when shutting down. However,
this usually takes less than a second, so there are only a few of these
quick flashes.
This command times out in 10 minutes and you must type it
again to continue outputting serial data.
