BOOT FAILURES

The procedures for troubleshooting a power-up failure established that:
• the hardware is functional
• the Ethernet interface is functional
• the CSMIM2 can communicate with the Ethernet.
If the CSMIM2 still is not booted, you must pinpoint the problem. The
boot error report can help in this process.
The CSMIM2 generates a boot error report only if it opens the
NOTE
boot file and an error occurs during the boot process.
Generally, two problems cause boot failures: the CSMIM2 is not
configured properly, or the load server host is not responding. The
CSMIM2 requests a boot either from a pre-defined load host, or by
broadcasting its boot request. When a host responds, the CSMIM2 loads
its operational code.
The CSMIM2 requires setting certain configuration parameters. Enter
these parameters with 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
CSMIM2 timed out while waiting for a response to its boot request; if this
field is empty, check the CSMIM2's configuration parameters.
