Page: 71 / 106

Note: Always power-cycle your N3700 storage system when you receive any of the
following errors. If the system repeats the error message, follow the
corrective action for that error message.
Table 16. POST error message descriptions
Error message or code Description Corrective action
[RAMX] No physical memory was
found by the system.
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.
[Cerr] Cache error. 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.
[Cer2] Cache error.
[EXC!] Exception. 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.
[RUN!] CFE (common firmware
environment) is jumping to
executable code.
This is not an error, but
rather a progress state
indicator used to help
troubleshoot the problem.
[HELO] Very early Init code. 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.
[L1CI] L1 cache INIT.
[L2CI] L2 Cache INIT.
[TST1] Simple POST test: cache of
both levels and tags.
[CPU1] CPU1 INIT.
[cpu1] CPU1 entering IDLE loop.
