Corrective action
This indicates that the
system doesn't see any
memory. Try resetting the
DIMM. See "Replacing the
SDRAM DIMM on the CPU
module" on page 37.
These are cache errors.
These errors indicate a bad
CPU. If a power-cycle
doesn't fix the problem, call
your IBM service
representative to replace the
CPU module.
This indicates that the
system took an exception
while in firmware. If it is
repeatable, this is likely a
software bug in the firmware.
Contact IBM technical
support and provide a log of
the error. If you can't get past
this error, boot the system
using the backup firmware
image.
This is not an error, but
rather a progress state
indicator used to help
troubleshoot the problem.
If the system stops on one of
these error codes, there is
likely a hardware problem.
First, try Step 1 below. If this
doesn't fix the problem,
proceed to the subsequent
steps until the problem is
fixed.
1. Power off the system,
then power it back on.
2. Try booting with the
backup firmware image.
See "Booting your N3700
storage system from a
backup firmware image"
on page 50.
3. Call your IBM service
representative to replace
the CPU module.
