server starts, power-off the system, then attach/install
the remaining components one at a time, until you
hear the 3-3-2 beep. The last FRU added prior to the
3-3-2 beep code is the failing FRU. Power-on the
server after the addition of each FRU, and power it off
prior to adding the next FRU. FRUs should be added
in the following order:
a. Front panel (after which you no longer need to
use jumper J11 on the I/O board to force power
on)
b. Power supplies (one at a time)
c. Processors (one at a time)
Note
Addition of the 5th processor automatically
requires installation of the second processor
daughter card and the cache coherency filter
DIMMs as well. Any of these may be the
failing FRU if the system fails at this point.
If the 3-3-2 beep occurs when this
combination is installed, do the following:
1. Remove the cache coherency filter
DIMMs.
2. Remove the first processor daughter
board with all its processors.
3. Reboot the system.
If the system boots without the 3-3-2 beep,
one or more of the cache coherency filter
DIMMs were the failing FRUs. Replace the
pair of DIMMs.
If the system does not boot with this
combination of processor and processor
daughter card, do the following:
1. Swap the processor with one from the
first processor daughter card
2. Reboot the system.
If the system boots without the 3-3-2 beep,
the processor just removed is the failing
FRU. Replace it.
If the system still gives the 3-3-2 beep, the
processor daughter board is the failing FRU.
Replace it.
d. Processor terminator cards (one at a time)
e. Memory card (maintaining DIMM pairs across
the memory cards)
f. Memory DIMM (maintaining DIMM pairs across
the memory cards)
g. System management adapter
h. SCSI backplane
i. Hardfiles (one at a time)
j. CDROM drive
