See "System Board Jumpers" in "Jumpers,Switches, and Connectors" for the location and settings of this jumper.

NOTICE: Your system supports one or two power supplies rated at an output of 1570 W.

NOTICE: If you connect the system to a power source in the range of 120 to 220 VAC, and if two powersupplies are installed, the second power supply serves as a redundant, hot-plug power source.


3 of 14 1/6/2012 3:00 PM

NOTICE: If you connect the system to a power source in countries where the standard power source is less than120 VAC, the power supply output will be limited to 1100 W. To support redundant power operation in thesesituations, you may need to operate the system in a limited configuration.

Removing a Power Supply

NOTICE: The system requires one power supply for the system to operate normally. The system is in theredundant mode when two power supplies are installed and both power supplies are connected to an AC powersource. Remove and replace only one power supply at a time in a system that is powered on. Operating thesystem with only one power supply installed and without a power supply blank installed for extended periods oftime can cause the system to overheat.

NOTICE: If only one power supply is installed, it must be installed in the left power supply bay (1).

NOTE: On a rack system, you may have to unlatch and lift the cable management arm if it interferes with powersupply removal. For information about the cable management arm, see the system's Rack Installation Guide.

Expansion Cards


4 of 14 1/6/2012 3:00 PM

Your system supports up to seven expansion cards, installed in connectors on a riser card. All expansion slotsaccommodate full-length cards except for slot 7, which is a half-length slot. The expansion slots are configured asfollows:

Slot 1 is an x8 lane-width PCI Express (PCIe) expansion slot.

Slot 2 is a 3.3-V, 64-bit, 133-MHz PCI-X expansion slot. This slot will accommodate 133-MHz, 100-MHz, 66-Hz,and 33-MHz PCI cards and PCI-X cards.

Slots 3, 4, and 5 are x4 lane-width PCIe expansion slots.

Slot 6 and slot 7 are 3.3-V, 64-bit, 100-MHz PCI-X expansion slots. These two slots will accommodate 100-MHz,66-MHz, and 33-MHz PCI cards and PCI-X cards.

NOTICE: If you add a remote access controller (RAC) card to add remote systems management capability toyour system, you must install the RAC card in slot 7.

Figure 6-5 shows the relative locations of these expansion-card slots

System MemoryYou can upgrade your system memory to a maximum of 64 GB by installing combinations of 256-MB, 512-MB, 1-GB,2-GB, or 4-GB (when available) 2-way registered ECC PC2-3200 (DDR2 400) memory.

NOTICE: If you remove your original memory modules from the system during a memory upgrade, keep themseparate from any new memory modules that you may have. Use only registered ECC PC2-3200 compliant (DDRII 400) memory modules.

The system memory is located on one to four memory riser cards. Each riser card has four memory module sockets ontwo channels (A and B), arranged as follows:

Bank 1: DIMM_1A and DIMM_1B

Bank 2: DIMM_2A and DIMM_2B

Figure 6-7 shows the memory module sockets on the memory riser card.

Figure 6-7. Memory Module Sockets on the Memory Riser Card

General Memory Module Installation Guidelines

Memory modules must be installed in pairs of matched memory size, speed, technology, and rank, beginning inbank 1 (DIMM_1A and DIMM_1B).

Memory riser cards must be installed in order beginning with riser A, then riser B, and so on.

The system supports both single-ranked and dual-ranked memory modules. If you install both single-ranked anddual-ranked memory modules on a riser card, the dual-ranked memory modules must be installed in bank 1(slots 1A and 1B). See Table 6-2.

Spare Bank Support

If four identical memory modules are installed on a given memory riser card, one pair of memory modules can serve asa spare bank in the event that memory errors reach a predefined threshold. You can enable the spare bank optionthrough the System Setup program. See "Using the System Setup Program" in your User's Guide.

NOTICE: If the spare bank option is enabled, neither memory mirroring nor memory RAID can be activated.

Memory Mirroring Support

Memory mirroring provides additional data redundancy and system availability. The system divides the total memory inhalf and copies identical sets of data to each half. (Consequently, the amount of available memory is half the amount ofphysical memory.) If a memory module fails, the data in the mirrored data set is still available, and the system canoperate normally until the memory module is replaced.

The system supports memory mirroring if either one or two pairs of memory riser cards containing identical sets ofmemory modules are installed in the system. You can enable memory mirroring through the System Setup program.See "Using the System Setup Program" in your User's Guide.

Memory RAID Support

Memory RAID is similar to parity RAID for drive arrays. Data is distributed across the four memory card risers. If amemory module fails, the data can be recovered using a parity algorithm.

To support memory RAID, four memory card risers with identical memory configurations must be installed. You canenable memory RAID through the System Setup program. See "Using the System Setup Program" in your User's Guide.

Table 6-1 and Table 6-2 show examples of different memory configurations. Table 6-2 lists the various allowablecombinations of single- and dual-ranked memory modules

Processors


10 of 14 1/6/2012 3:00 PM

You can upgrade the system processor(s), to take advantage of future options in speed and functionality, or addadditional processors. Each processor and its associated internal cache memory are contained in a pin grid array (PGA)package that is installed in a ZIF socket on the system board.

NOTICE: Your system supports either one, two, or four processors. Three-processor operation is not supported.

NOTICE: If you add a third and fourth processor to your system, you must also install a voltage regulatormodule (VRM) for each processor. See "Installing a Processor VRM."

Removing a Processor




Remove the cooling shroud. See "Removing the Cooling Shroud."3.

NOTICE: When you remove the heat sink, the possibility exists that the processor might adhere to the heat sinkand be removed from the socket. It is recommended that you remove the heat sink while the processor is stillwarm.

NOTICE: Never remove the heat sink from a processor unless you intend to remove the processor. The heatsink is necessary to maintain proper thermal conditions.

While pressing firmly on the blue tab on the end of the heat-sink retention clip, compress the sides of theretention clip together until the clip disengages from the slots in the socket, and then slide the clip forward. SeeFigure 6-11.

4.

Figure 6-11. Installing and Removing the Heat Sink

If the heat sink has not separated from the processor, carefully rotate the heat sink in a clockwise, thencounterclockwise, direction until it releases from the processor. Do not pry the heat sink off of the processor.

5.

Lift the heat sink off of the processor and set the heat sink upside down so as not to contaminate the thermalgrease.

6.

Pull the socket-release lever straight up until the processor is released from the socket. See Figure 6-12.7.

NOTICE: If you are removing processor 1 or processor 3, pull upwards on the blue plastic tab next to the socketto open the socket-release lever.

Figure 6-12. Installing and Removing a Processor


11 of 14 1/6/2012 3:00 PM

Lift the processor out of the socket and leave the release lever up so that the socket is ready for the newprocessor.

8.

NOTICE: Be careful not to bend any of the pins when removing the processor. Bending the pins canpermanently damage the processor.

Installing a Processor




Remove the cooling shroud. See "Removing the Cooling Shroud."3.

Unpack the new processor.4.

If any of the pins on the processor appear bent, see "Getting Help."

If you are adding an additional processor, remove the processor filler blank from the socket by pressing inwardon the two tabs on the filler blank and lifting the filler blank out of the system. See Figure 6-13.

5.

Figure 6-13. Removing a Processor Filler Blank

Align the pin-1 corner of the new processor with the pin-1 corner of the ZIF socket. See Figure 6-12.6.

NOTICE: Identifying the pin-1 corners is critical to positioning the processor correctly.

Identify the pin-1 corner of the processor by locating the tiny gold triangle on one corner of the processor. Placethis corner in the same corner of the ZIF socket identified by a corresponding triangle.


12 of 14 1/6/2012 3:00 PM

Install the processor in the socket.7.

NOTICE: Positioning the processor incorrectly can permanently damage the processor and the system when youturn it on. When placing the processor in the socket, be sure that all of the pins on the processor enter thecorresponding holes. Be careful not to bend the pins.

If the release lever on the processor socket is not positioned all the way up, move it to that position.a.

With the pin-1 corners of the processor and socket aligned, set the processor lightly in the socket, makingsure all pins are matched with the correct holes in the socket.

b.

Because the system uses a ZIF processor socket, do not use force, which could bend the pins if theprocessor is misaligned. When the processor is positioned correctly, it drops down into the socket withminimal pressure.

When the processor is fully seated in the socket, rotate the socket release lever back down until it snapsinto place, securing the processor.

c.

Install the heat sink.

Using a clean lint-free cloth, remove the existing thermal grease from the heat sink.a.

8.

NOTE: Use the heat sink that you removed in step 6.

Apply thermal grease evenly to the top of the processor.b.

Place the heat sink onto the processor. See Figure 6-11.c.

Squeeze the sides of the heat-sink retention clip together and press down on the blue tab. When the lowercorners of the clip fit into the slots in the socket, release the sides of the clip to lock the heat sink in place.See Figure 6-11.

d.

Reinstall the cooling shroud. See "Installing the Cooling Shroud."9.


As the system boots, it detects the presence of the new processor and automatically changes the systemconfiguration information in the System Setup program.

Press to enter the System Setup program, and check that the processor information matches the newsystem configuration.

11.

See your User's Guide for instructions about using the System Setup program.
