BOOT Failures

4-8 Remote Annex 5393/PRI Hardware Installation Guide
The procedures for troubleshooting a power-up failure established
that:
The hardware is functional.
The Ethernet interface is functional.
The Remote Annex can communicate with the Ethernet.
If the Remote Annex still is not booted, you must pinpoint the
problem. The boot error report can help in this process.
The Remote Annex 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 Remote Annex is not configured properly.
The load server host is not responding.
The Remote Annex requests a boot image from a pre-defined load
host or by broadcasting a boot request. When a host responds, the
Remote Annex loads its operational image.
The Remote Annex requires setting certain configuration parameters.
Enter these parameters using the Monitor Mode commands for the
initial boot sequence. See Chapter 3 for more information on these
commands.
If the problem is a non-responsive host, the boot error report displays
that information under the Rsp T/O's field. This field indicates that
the Remote Annex timed out while waiting for a response to its boot
request; if this field is empty, check the Remote Annex's configuration
parameters.
