http://primeserver.fujitsu.com/primergy/system.html


Main memory

– The higher the capacity, the further away from the CPU the memory module has to be mounted per channel!

– Performance channel mode is installed the same as independent channel mode, but requires identical modules for the same slot on all channels per CPU!

– Empty DIMM slots of CPU 1 must be fitted with dummy DIMM modules to ensure sufficient cooling of the system.

3.2.3.1 Independent Channel Mode

This mode allows the memory modules to be arranged in any order in each channel. The channels do not have to be populated identically.

● You can use memory modules with different speed ratings within a channel, whereby the settings of the slowest memory module are used for each channel.

● All channels work with the fastest common frequency.

● All timings except for the clock frequency can vary between the channels.

● Always start by populating the main memory at CPU 1.

V CAUTION!

The empty DIMM slots of CPU 1 must be fitted with dummy DIMM modules to ensure sufficient cooling of the system. In addition always an air duct has to be mounted to cover the DIMM modules and the dummy DIMM modules of CPU1.

● If memory modules with different memory capacities are to be installed for a CPU then the rule applies that the higher the capacity, the further away from the CPU the memory module has to be mounted per channel.

The DIMM sockets must be populated per channel in the following order:

CPU 1: DIMM1A -> DIMM1B -> DIMM1CCPU 2: DIMM1D -> DIMM1E -> DIMM1FCPU 1: DIMM2A -> DIMM2B -> DIMM2CCPU 2: DIMM2D -> DIMM2E -> DIMM2FCPU 1: DIMM3A -> DIMM3B -> DIMM3CCPU 2: DIMM3D -> DIMM3E -> DIMM3F


Main memory

3.2.3.2 Performance Channel Mode

In this mode, the maximum performance and capacity can be achieved.

● All three channels of a CPU must be populated identically as regards the size and organization of the memory modules.

● The slots within a channel of CPU 1 do not have to be populated identically, but the corresponding slots of all three channels of CPU 1 must be populated identically.

● Memory modules with different clock frequencies and different speed ratings can be used within a channel, whereby the settings of the slowest memory module are used for this channel.

V CAUTION!


3.2.3.3 Mirrored Channel Mode

In this mode, channels A and B of CPU 1 and channels D and E of CPU 2 form exact copies of each other.

● Channel A and channel B of CPU1 must be fitted identically and channel D and channel E of CPU2 must be fitted identically (channel C and F cannot be used in Mirrored Channel Mode since the "counterpart" is missing).

● The slots within a channel do not need to be equipped identically. However, the corresponding slots in channels A and B must be equipped identically.

● Memory modules with different clock frequencies and different speed ratings can be used within a channel, whereby the settings of the slowest memory module are used for the channel.

● In Mirrored Channel Mode, the total main memory available in the system is half as large as the installed memory.

V CAUTION!



Main memory

3.2.3.4 Spare Channel Mode

I This mode is only supported by Intel® processors of type Intel® Xeon® processors of the 5600 series.

In this mode, channel C forms a replacement for the two channels A and B and channel F forms a replacement for the two channels D and E. Channels C and F are not available as regular main memory. The channels are populated in the same way as in Performance Channel Mode.

● All three channels must be populated identically as regards the size and organization of the memory modules.

● The slots within a channel do not have to be populated identically, but the corresponding slots of all three channels must be populated identically.

● Memory modules with different clock frequencies and different speed ratings can be used within a channel, whereby the settings of the slowest memory module are used for the channel.

● The timings in the active channels (A and B) and in the spare channel (C) can be set differently.

● Only 2/3 of the maximum memory bandwidth is available in Spare Channel Mode.

● In Spare Channel Mode, the total main memory available in the system is 2/3 the size of the installed memory.

V CAUTION!



Main memory

3.2.4 Memory speed

The maximum DDR3 memory speed depends on the memory configuration on one memory channel and on the CPU speed.

One DIMM per channel = max. 1333 MHz, two DIMMs per channel = max. 1333 MHz for 1.5 V memory / max. 1066 MHz for 1.35 V memory, three DIMMs per channel = max. 800 MHz. The memory channel with the lowest speed defines the speed of all CPU channels in the system.

Screen resolution

3.3 Screen resolution

Depending on the operating system used the screen resolutions in the following table refer to the graphic controller on the system board. The graphic controller is integrated in the iRMC (integrated Remote Management Controller).

3.4 Temperature/system monitoring

Temperature and system monitoring aim to reliably protect the computer hardware against damage caused by overheating. In addition, any unnecessary noise is also prevented by reducing the fan speed, and information is provided about the system status.

The temperature and system monitoring are controlled by the iRMC S2 (integrated Remote Management Controller).

The following functions are supported:

Temperature monitoring

Measurement of the processor and the system internal temperature by an onboard temperature sensor, measurement of the ambient temperature by a I2C temperature sensor.

Fan control

The fans are regulated according to temperature.

Sensor monitoring

The removal of, or a fault in, a temperature sensor is detected. Should this happen all fans monitored by this sensor run at maximum speed, to achieve the greatest possible protection of the hardware.

Screen resolution Max. color depth Max. frequency

1280 x 1024 Hz 24 Bit 60 Hz

1600 x 1200 Hz 16 Bit 60 Hz


Temperature/system monitoring

Power monitoring

When voltage exceeds warning level high or falls below warning level low an alert will be generated.

System Event Log (SEL)

All monitored events of the system board are signalized via the Global Error LED and recorded in the System Event Log. The events can be retrieved in the BIOS Setup or via the ServerView Operations Manager.

Diagnostic LEDs

For signalisation of failures LEDs are situated on the system board.


LED indicators

3.5 LED indicators

3.5.1 Internal indicators

There are several diagnostic LEDs on the system board, which are not visible when the housing is closed.

By pressing the CSS button (INDICATE CSS BUTTON, see item 5 in the following figure), the defective component can also be displayed in the power-off state (power plug disconnected).

Switch 3 - BIOS Recovery

Switch 3 allows the system BIOS to be restored after an erroneous update. To restore the system BIOS you need a "BIOS flashing medium" (for more information, refer to the BIOS manual or contact the customer service team).

Switch 4 - (for service only)

Switch 4 Flash descriptor override strap (for service only).

on The system starts from the "BIOS flashing medium" (ODD, USB stick) and reprograms the system BIOS on the board.

off The system starts with the system BIOS of the system board (default setting).


4 Replacing the lithium batteryIn order to save the system information permanently, a lithium battery is installed to provide the CMOS-memory with a current. When the charge is too low or the battery is empty, a corresponding error message is provided. The lithium battery must then be replaced.

V CAUTION!

The lithium battery must be replaced with an identical battery or a battery type recommended by the manufacturer (CR2032).

Do not throw lithium batteries into the trash can. It must be disposed of in accordance with local regulations concerning special waste.

Make sure that you insert the battery the right way round. The plus pole must be on the top!

Figure 10: Replacing the lithium battery

Ê Press the locking spring into direction of the arrow (1), so that the lithium battery jumps out of its socket.

Ê Remove the battery (2).

Ê Insert a new lithium battery of the same type into the socket (3) and (4).
