Cpu/Memory/Sba - HP Integrity rx2660 User's & Service Manual

5. The next step would be to add one pair of DIMMs. Remember to remove the ac power cord(s)
before making this configuration change.
Here is the output of the MP DF command you should expect at this point (this example has
two ranks of DIMMs installed). Your display may not exactly match the display shown:
FRU IDs:
--------
0152-DIMM0D 0001-Memory 0002-Power Converter
0003-Power Supply 0 0004-Power Supply 1 0005-Diagnostic Panel
0006-Front Panel 0128-DIMM0A 0136-DIMM0B
0144-DIMM0C 0160-DIMM1A 0168-DIMM1B
0176-DIMM1C 0184-DIMM1D 0000-Motherboard
If you do not see all of the above CRU IDs then concentrate on the missing CRU ID(s). You
should eventually end up with the following Alert (IPMI) event for this action as read from
the SEL. Your display may not exactly match the display shown:
Log Entry 3: Dec 2005 21:50:43
Alert Level 5: Critical
Keyword: Type-02 257100 2453760
Missing FRU device - CPU 0 PIROM
Logged by: Baseboard Management Controller,
Sensor: Entity Presence
0x2041CB3DB3020040 FF20807115250300
If you do show the Alert level 5 "Missing CRU device - CPU 0 PIROM" then continue to the
next step.
6. Insert the CPU board CRU with at least CPU 0 processor installed. When you add the CPU
board CRU and turn on system power, the cooling fans should turn on and stay on and the
DF command output should look something like the following. Your display may not exactly
match the display shown:
FRU IDs
-------
0001-Memory 0002-Power Converter 0003-Power Supply 0
0004-Power Supply 1 0005-Diagnostic Panel 0006 Front Panel
0007-Disk Management 0008-Disk backplane 0010-Processor Board
0012-Power Pod 0 0013-Power Pod 1 0032-CPU 0 PIROM
0033-CPU 1 PIROM 0036-Processor 0 RAM 0037-Processor 1 RAM
0128-DIMM0A 0136-DIMM0B 0144-DIMM0C
0152-DIMM0D 0160-DIMM1A 0168-DIMM1B
0176-DIMM1C 0184-DIMM1D 0000-Motherboard
If the installed CRUs are all functional then the system should initiate POST on all processors.
It is recommended to observe the system console output through "Live Logs" to ensure that
POST is initiated and completes without error.
If power-on-self-test (POST) does not start after a few seconds then suspect some sort of
system board or processor problem. Typical problems show up in the SEL or FWP. If the
IMPI event logs do not point to a root cause, then escalate to bring in expert assistance.

CPU/Memory/SBA

All of the CPU, Memory controller, and System Bus Adapter (SBA or I/O rope controller) functions
reside on the system board; DIMMs reside on the system board; and the Local Bus Adapter (LBAs
or PCI-X bus controller chips) reside on the I/O Backplane and the system board along with
customer Host Bus Adapter (HBA device controller) I/O cards. This section discusses the roles
of logical CPUs, physical memory ranks, and the rope interfaces in the SBA logic of the zx2 chip.
