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 CPMa 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.

When the system finds the boot.ldr
file, the system processes the initialization parameters from the BOF (boot option file). The BOF should be on the same drive as the boot.ldr
file. If the BOF cannot be found or loaded, then the system prompts the user for alternate software and configuration file locations.
When the system software is successfully loaded, control is passed from the boot loader file to the system software. The system software attempts to locate the configuration file as configured in the BOF. The configuration file includes chassis, CPM-a, IOM-a, MDA-a, and port configurations, as well as system, routing, and service configurations.
It is important that cables connected to the Console port on the 7750 SR-a chassis are correctly terminated and terminal servers should be correctly configured so as to not negatively affect the functioning of the node.
Noisy lines can be interpreted by the node as keystrokes and could interrupt the boot sequence resulting in an outage. After reboot, the CPM can go into a continuous reboot cycle if the boot process is interrupted by random characters received on the Console port.
To prevent random characters received on the Console port, terminate all console connections. If a terminal server is connected to the 7750 SR-a CPM-a ensure that it is configured to not send unwanted characters to the CPM-a that could interrupt the boot cycle.
For example, configure a no exec
or equivalent CLI command on the terminal server.
