Rebooting...
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.
