Change the Boot Mode

This section describes the available boot modes available and contains instructions
for changing the boot mode from the craft port using a diagnostic PC.
See Connect the CA SYNC Port (on page 24) for connection instructions.

Boot Modes

Three boot modes (0 through 2) exist and are described in the following list:
0 - Skip BootP (Standalone mode) – This mode bypasses the boot mode when

you power on the MQAM. Use the Skip BootP mode when operating in
Standalone mode, when provisioning and monitoring the MQAM from the front
panel or the craft port, or when operating without the control of the DNCS. This
mode skips the BOOTP and TFTP processes and jumps directly to the application
code.
1 - Attempt BootP One Time (Attempt Bootp Once mode) – This mode is not

normally used in network operation. If used when the MQAM is connected to
the network and the network connection is lost or reset, the MQAM must be
rebooted. This mode attempts each BOOTP and TFTP step only once. If a failure
occurs during any step, the step is skipped; the MQAM attempts the remaining
steps and eventually attempts to start the application. If the BOOTP and/or
configuration file TFTP steps are aborted due to errors, the MQAM may not
communicate with the DNCS.
2 - Bootp Until Successful (Boot Until Successful mode) – This is the default

mode. This mode continues to boot until the MQAM receives an IP address and
all download images. This setting is useful when upgrading the software.
Booting until successful ensures that the MQAM completes all startup
procedures successfully. Use the standard mode (boot forever until successful)
when a network controller such as the DNCS monitors and provisions the
MQAM through the Ethernet port. This mode attempts to boot and to TFTP the
configuration file and any requested boot and/or application code files until the
entire process is successful. If an error occurs at any step, the MQAM restarts
until a successful boot occurs.
Important! Do not select this setting when operating the MQAM outside a DNCS
environment.
