4-11 Remote Annex 4000 Hardware Installation Guide
Chapter 4 Troubleshooting Procedures
Boot Failures
The procedures for troubleshooting a power-up failure
established that:
❑
The hardware is functional.
❑
The Ethernet interface is functional.
❑
The Remote Annex 4000 can communicate with the
Ethernet.
If the Remote Annex 4000 still is not booted, you must pinpoint the
problem. The boot error report can help in this process.
The Remote Annex 4000 generates and displays a boot error
report only if it has opened the boot file and an error occurs
during the boot process.
Generally, two problems cause boot failures: the Remote Annex 4000
is not configured properly, or the load server host is not responding.
The Remote Annex 4000 requests a boot either from a pre-defined
load host, or by broadcasting its boot request. When a host responds,
the Remote Annex 4000 loads its operational code.
The Remote Annex 4000 requires setting certain configuration
parameters. Enter these parameters using the ROM Monitor
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 4000 timed out while waiting for a response to its
boot request; if this field is empty, check the Remote Annex 4000’s
configuration parameters.
