Chapter 3 ROM Monitor Commands
The RAC boots from the defined preferred load host. If the preferred load
host is not defined or does not respond, the RAC optionally broadcasts
on the Ethernet and loads from the first host that responds, if the load
broadcast flag is set.
To initiate loading, the RAC sends a load request message to the selected
host. After receiving a response, the RAC loads its operational code to
RAM. When loading is complete, it transfers control to the newly loaded
program. The RAC displays a symbol on the console terminal for each
data block received during the boot.
When the RAC begins to boot, it displays the load server host's IP address.
If the unit does not boot successfully after several attempts, it displays
the message boot attempt failed; if the RAC opens the boot file and an
error occurs during the boot process, it displays a boot error report on the
console terminal and returns to the ROM Monitor. The boot error report
can help determine the cause of the boot failure (see Boot Error Report
on page 4-11).
During a boot, the console terminal may display four possible status
symbols: "." indicates received data blocks, "?" indicates unanswered
requests, "*" indicates transmission errors, and "! ~XXXX~" is a status
word from the Ethernet chip on the RAC indicating a serious problem
with the Ethernet connection (if this symbol appears in your boot
command display, contact the Technical Solutions Center).
