Extender Board Switches and Jumpers
The processor extender board includes switches and jumpers. These switches are factory preset
and must not be altered except by an HP Service Representative.
Replacing the Processor Extender Board
To replace the processor extender board, follow these steps:
1. Ensure that the extraction levers are positioned in the outward, unlocked position.
2. Align the processor extender board with the left and right card guides.
3. Slide the processor extender board in until it begins to seat in the socket located on the
midplane riser board.
4. Push the extraction levers inward to the locked position in order to fully seat the processor
extender board into the midplane riser board socket.
5. Replace the front cover and front bezel.
6. Verify processor operation by using the system utilities.
•
To verify operation, use the iLO MP commands and the BCH commands.
• To exercise the processor, use
MAKODIAG
provided by the offline diagnostic environment.
Installing Memory
The standard configuration of HP 9000 rp4410 and rp4440 servers include a 16-DIMM memory
extender board. This extender board must contain a minimum of 1 GB of memory (four 256 MB
DIMMs loaded in quad 0 [connectors 0A, 0B, 0C, and 0D]). (
Figure 3-28 )
An optional 32-DIMM memory extender board is available to replace the 16-DIMM memory
extender board. This extender board must contain a minimum of 1 GB of memory (four 256 MB
DIMMs loaded in quad 0 [connectors 0A, 0B, 0C, and 0D]). (
Figure 3-29 )
You can insert additional DIMMs into both 16- and 32-DIMM boards. When adding DIMMs,
you must use a minimum of four like-sized DIMMs in the next available quad.
Supported DIMM Sizes
You can install up to 128 GB of memory in the server. Supported DIMM sizes are as follows:
•
256 MB, 512 MB, 1 GB, 2 GB, 4 GB
Dissimilar DIMM sizes can be used across the extender board, but all four DIMMs in each quad
must match. For cooling purposes, you must install DIMM fillers into unused connectors.
DIMM Slot Fillers
Both the 16- and 32-DIMM extender boards must have DIMM slot filler boards placed over all
unfilled DIMM connectors. As you fill DIMM quads with additional memory, you must remove
the DIMM slot fillers covering the connectors. All remaining DIMM fillers in unused connectors
must remain in place to maximize internal cooling.
NOTE: One DIMM filler board covers two adjacent DIMM connectors. Remove DIMM slot
fillers as you add memory and you will always retain the correct configuration.
Table 3-8 and Figure 3-28 show the DIMM filler requirements and configuration for the 16-DIMM
memory extender board.
Table 3-8 DIMM Filler Requirements for 16-DIMM Extender Board
Fillers Required
1
DIMMs Loaded
Six fillers total: Two fillers each in quads 1, 2, and 3 4 DIMMs in quad 0
Four fillers total: Two fillers in quads 2 and 3 8 DIMMs in quads 0 and 1
