This section provides information about installing processors
and memory. Processors and memory are located under the top cover. Removing
the Top Cover | |
To remove the top cover, perform the following steps: Loosen the captive T-15 screws that hold
the top cover in place. Grasp the strap handle, raise the cover slightly, and
pull the cover toward the front of the server to free the cover
tabs from the slots in the rear of the chassis.
Installing
Processors | |
Removing
the Processor Extender BoardTo remove the processor extender board, perform the following
steps: Press the latch on the extraction levers
located on each side of the processor extender board (see Figure 2-6 “Processor Extender Board”). Pull up on the extraction levers to free the processor
extender board from the socket located on the system baseboard.
| | | |  | WARNING! Processor connector pins are easily bent during
installation. Use care to prevent damage when installing CPU modules
on the processor extender board. Ensure that all processor pins
enter the extender board connector evenly and simultaneously. Failure
to heed this warning can result in processor failure. | | | | |
| | | |  | NOTE: Experience has shown that, when installing two (or four) processors,
it is better to install the processor which is toward the rear of
the extender board before installing a processor at the front of
the extender board. This means: install processor CPU1 before installing
processor CPU0. Similarly, install processor CPU3 before installing
processor CPU2. | | | | |
To install a processor, perform the
following steps: If you are installing processor module CPU1
and module CPU0 is already installed, remove CPU0 before installing
CPU1. Reinstall module CPU0 after installing module CPU1. If you are installing processor module CPU3 and module
CPU2 is already installed, remove CPU2 before installing CPU3. Reinstall
module CPU2 after installing module CPU3. Locate the installation position and connector socket
on the extender board. Ensure that the socket is clean and that
holes are not blocked. Ensure that the cam on the processor socket (Figure 2-7 “Processor Installation”, item 7) is in the unlocked, fully counterclockwise
position. Use a 2.5 mm hex driver to unlock the cam. Remove the retention cover (Figure 2-7 “Processor Installation”, item 4) from the CPU module. Carefully lower the CPU module into position, using
the mounting screw holes (Figure 2-7 “Processor Installation”,
item 2) to align the CPU module with the extender board socket. Carefully position the CPU module above the processor
socket using the alignment guide pins (Figure 2-7 “Processor Installation”, item 6) to align the processor connector with
the extender board socket. Using the alignment tabs on the processor socket, and
corresponding notches on the processor connector, lower the connector
pins into the socket (see Figure 2-8 “Processor
Connector Alignment Tabs” for
location of tabs and notches). Ensure that the socket and connector
are flush against each other before proceeding. Insert the 2.5 mm hex driver through the opening in
the CPU module frame (Figure 2-7 “Processor Installation”,
item 5), and rotate the cam on the processor socket (Figure 2-7 “Processor Installation”, item 7) 180 degrees clockwise. Connect the processor power cable (Figure 2-7 “Processor Installation”, item 1). Place the processor retention cover (Figure 2-7 “Processor Installation”, item 4) over the processor. Tighten the captive T-15 screws (Figure 2-7 “Processor Installation”, item 3) to secure the processor retention cover. | | | | | NOTE: When installing the processor retention
cover, the screws should be tightened in sequence as shown in Figure 2-7 “Processor Installation”. Each screw should be turned
2-3 times until all screws are bottomed out. | | | | |
Replacing
the Processor Extender BoardTo replace the processor extender board, perform the following
steps: Ensure the extraction levers are positioned
in the outward, unlocked position. Align the processor extender board with the front and
rear card guides. The end of the board which is closer to the CPU
module(s) should be toward the front of the server chassis. Slide the processor extender board down until it begins
to seat in the socket located on the system baseboard. Push the extraction levers inward to the locked position
in order to fully seat the processor extender board.
Installing
Memory | |
DIMMs are installed on memory extender boards located in the
top service bay. If only one memory extender board is installed,
it must be located in slot 0 (see Figure 2-5 “Top Cover Removal”). A maximum of two memory extender boards may be installed
per system. Each memory extender board can hold up to 24 DIMMs.
Dimms of different sizes can be installed on a memory extender board,
but they must be grouped by size. By replacing the DIMMs in your server, or installing additional
DIMMS, you can increase the amount of memory in your server. Several
different DIMM sets are available. The DIMMs are listed in the parts
section of this guide, and at http://www.hp.com. (Search using keyword
rx5670.) Memory must be installed in groups of four identical DIMMs.
For a minimally loaded system, DIMMs will be loaded in slots 0A,
0B, 0C and 0D. This collection of slots is referred to as Rank 0.
The next set of DIMMs loaded are installed into slots 1A, 1B 1C
and 1D. The process of loading additional DIMMs continues in a similar
manner through the last set of DIMMs, which is installed in slots
5A, 5B, 5C, and 5D. Memory
Performance ConsiderationsFor best memory performance, install a second memory extender
board and distribute DIMM installation between them. Install DIMMs
in Rank 0 of memory extender board MX0, then install DIMMs in Rank
0 of memory extender board MX1. Memory performance increases as
the difference in memory installed between memory board extenders
is decreased. Optimal memory performance is obtained when the differential
is 0. In addition, memory performance will also be increased by
loading the highest capacity DIMMs in the lower ranks. Removing
a Memory Extender BoardTo remove a memory extender board, perform the following steps: Press the latch on the extraction levers
located on each side of the memory extender board. Pull up on the extraction levers to free the memory
extender board from the socket located on the system baseboard.
To install memory, perform the following steps: Loosen the captive T-15 screws that secure
the DIMM retainer to the memory extender board (see Figure 2-9 “Memory Extender Board”). Remove the DIMM retainer from the memory extender board. Install the four DIMMs of a DIMM set into the sockets
of a single rank on the memory extender board. Ranks are identified
on the memory extender board and in Figure 2-10 “Memory DIMM Location”. (Rank and socket are also identified on the memory
extender board.) Push gently and evenly on the memory DIMM until it seats
in the socket. | | | | | NOTE: Ensure that the extraction levers are
in the closed position. | | | | |
Repeat steps 3 and 4 until all memory DIMMs are seated
in their sockets. Align the DIMM retainer on the memory extender board. Tighten the captive T-15 screws to secure the DIMM retainer
to the memory extender board.
Installing
a Memory Extender Board | | | |  | CAUTION: Ensure that a memory extender board is installed
in slot MX0 (right slot). If the system is configured with only
one memory extender board a memory filler panel must be installed
in slot MX1 (left slot). Failure to observe this caution will result
in system failure. | | | | |
To install a memory extender board, perform the following
steps: Remove the filler panel located in slot MX1
if you are installing a second memory extender board. Ensure the memory extender board extraction levers are
positioned in the outward, unlocked position. Align the memory extender board with the front and rear
card guides. The memory extender board(s) installed as shown in Figure 2-5 “Top Cover Removal”. Slide the memory extender board down until it begins
to seat in the socket located on the system baseboard. Push the extraction levers inward to the locked position
in order to fully seat the memory extender board.
Replacing
the Top Cover | |
To replace the top cover, perform the following steps: Align the tabs at the rear of the top cover
with the corresponding slots in the chassis and fully seat the tabs
into the slots. Seat the top cover in the top of the service bay and
tighten the captive T-15 screws that hold the top cover in place.
