Troubleshooting Initial Startup
If the Status LED does not light after 30 s, as described in Component LED Verification on
page 127, the compact flash card is most likely faulty.
If the system cannot load or cannot find the boot.ldr file on the cf3: slot, the Status LED
on the CPM turns off and the system checks for a manual boot sequence interruption. Perform
a manual boot sequence interruption by connecting a terminal to a Console port and pressing
any key when prompted by the display. Unless an unsuccessful system initialization is
manually interrupted, the system will continuously reboot in an attempt to successfully find
and load the boot.ldr file. Insert a compact flash card with the appropriate boot.ldr
file into the cf3: slot, as described in Replacing the Internal Compact Flash Card on the CPM-
a on page 195.
When the system finds the boot.ldr file, the system processes the initialization parameters
from the BOF. The BOF must be on the same drive as the boot loader file. If the BOF cannot
be found or loaded, the system prompts for a different image and configuration location.
When the image is successfully loaded, control is passed from the boot loader file to the
image. The runtime image attempts to locate the configuration file as configured in the BOF.
The configuration file include chassis, IOM-a, MDA-a, and port configurations, as well as
system, routing, and service configurations.
The following example shows the output when either no flash is present or the boot.ldr file
cannot be found.
