Boot Failures

Installing the Model 8000 Remote Access Concentrator

The procedures for troubleshooting a power-up failure established that:
• The hardware is functional.
• The Ethernet interface is functional.
• The RAC can communicate with the Ethernet.
If the RAC still does not boot, you must locate the problem. The boot
error report can help in this process.
The RAC generates a boot error report only if it opens the boot
file and an error occurs during the boot process.
Generally, two problems cause boot failures:
• The RAC is not configured properly.
• The load server host is not responding.
The RAC requests a boot image from a predefined load host or by
broadcasting a boot request. When a host responds, the RAC loads its
operational image.
You must set certain configuration parameters for the RAC. Enter these
parameters using Monitor mode commands for the initial boot sequence.
See Chapter 3 for more information about these commands.
If the problem is a nonresponsive host, the boot error report displays that
information in the Rsp T/O's field. This field indicates that the RAC timed
out while waiting for a response to its boot request; if this field is empty,
check the RAC's configuration parameters.
