Power supply unit indicator codes

AC power supply units (PSUs) have an illuminated translucent handle that serves as an indicator. The DC PSUs have an LED that serves

as an indicator. The indicator shows whether power is present or if a power fault has occurred.

Figure 11. AC PSU status indicator

Table 14. AC PSU status indicator codes

Power indicator codes Condition

Green A valid power source is connected to the PSU and the PSU is operational.

Blinking amber Indicates a problem with the PSU.

Not illuminated Power is not connected to the PSU.

Blinking green When the firmware of the PSU is being updated, the PSU handle blinks green.

CAUTION: Do not disconnect the power cord or unplug the PSU when updating firmware. If

firmware update is interrupted, the PSUs do not function.

Blinking green and turns off When hot-plugging a PSU, the PSU handle blinks green five times at a rate of 4 Hz and turns off. This

indicates a PSU mismatch with respect to efficiency, feature set, health status, or supported voltage. If

two PSUs are installed, both the PSUs must have the same type of label; for example, Extended Power

Performance (EPP) label. Mixing PSUs from previous generations of PowerEdge servers is not supported,

even if the PSUs have the same power rating. This results in a PSU mismatch condition or failure to turn

the system on.

CAUTION: When correcting a PSU mismatch, replace only the PSU with the blinking

indicator. Swapping the PSU to make a matched pair can result in an error condition and

unexpected system shutdown. To change from a high output configuration to a low output

configuration or vice versa, you must turn off the system. AC PSUs support both 240 V and

120 V input voltages with the exception of Titanium PSUs, which support only 240 V. When

two identical PSUs receive different input voltages, they can output different wattages, and

trigger a mismatch.

Processor Settings details

About this task

The Processor Settings screen details are explained as follows:

Option Description

Logical Processor Enables or disables the logical processors and displays the number of logical processors. If this option is set to

Enabled, the BIOS displays all the logical processors. If this option is set to Disabled, the BIOS displays only one

logical processor per core. This option is set to Enabled by default.

CPU Interconnect

Speed

Enables you to govern the frequency of the communication links among the processors in the system.

NOTE: The standard and basic bin processors support lower link frequencies.

The options available are Maximum data rate, 10.4 GT/s, and 9.6 GT/s. This option is set to Maximum data

rate by default.

Maximum data rate indicates that the BIOS runs the communication links at the maximum frequency that is

supported by the processors. You can also select specific frequencies that the processors support, which can

vary.

For best performance, you should select Maximum data rate. Any reduction in the communication link frequency

affects the performance of non-local memory accesses and cache coherency traffic. Besides, it can slow access

to non-local I/O devices from a particular processor.

However, if power-saving considerations outweigh performance, you might want to reduce the frequency of the

processor communication links. If you do this, you should localize memory and I/O accesses to the nearest NUMA

node to minimize the impact to system performance.

System memory

System memory guidelines

The PowerEdge systems support DDR4 Registered DIMMs (RDIMMs), Load Reduced DIMMs (LRDIMMs), Non-Volatile DIMMs

(NVDIMM-Ns), and Intel Optane Data Center Persistent Memory Modules (DCPMMs). System memory holds the instructions that are

executed by the processor.

Your system contains 24 memory sockets split into two sets of 12 sockets, one set per processor. Each 12-socket set is organized into six

channels. Six memory channels are allocated to each processor. In each channel, the release tabs of the first socket are marked white, and

the second socket black.

General memory module installation guidelines

To ensure optimal performance of your system, observe the following general guidelines when configuring your system memory. If your

system's memory configurations fail to observe these guidelines, your system might not boot, stop responding during memory

configuration, or operate with reduced memory.

The memory bus may operate at frequency can be 2933 MT/s, 2666 MT/s, 2400 MT/s, or 2133 MT/s depending on the following

factors:

90 Installing and removing system components

• System profile selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])

• Maximum supported DIMM speed of the processors. For memory frequency of 2933 MT/s, one DIMM per channel is supported.

• Maximum supported DIMM speed of the processors.

• Maximum supported speed of the DIMMs

NOTE: MT/s indicates DIMM speed in MegaTransfers per second.

The system supports Flexible Memory Configuration, enabling the system to be configured and run in any valid chipset architectural

configuration. The following are the recommended guidelines for installing memory modules:

• All DIMMs must be DDR4.

• RDIMMs and LRDIMMs must not be mixed.

• NVDIMMs and LRDIMMs must not be mixed.

• NVDIMMs and RDIMMs can be mixed.

• 64 GB LRDIMMs that are DDP (Dual Die Package) LRDIMMs must not be mixed with 128 GB LRDIMMs that are TSV (Through Silicon

Via/3DS) LRDIMMs.

• x4 and x8 DRAM based memory modules can be mixed.

• Up to two RDIMMs can be populated per channel regardless of rank count.

• Up to two LRDIMMs can be populated per channel regardless of rank count.

• A maximum of two different ranked DIMMs can be populated in a channel regardless of rank count.

• If memory modules with different speeds are installed, they will operate at the speed of the slowest installed memory module(s).

• Populate memory module sockets only if a processor is installed.

○For single-processor systems, sockets A1 to A12 are available.

○For dual-processor systems, sockets A1 to A12 and sockets B1 to B12 are available.

• Populate all the sockets with white release tabs first, followed by the black release tabs.

• When mixing memory modules with different capacities, populate the sockets with memory modules with the highest capacity first.

For example, if you want to mix 8 GB and 16 GB memory modules, populate 16 GB memory modules in the sockets with white release

tabs and 8 GB memory modules in the sockets with black release tabs.

• Memory modules of different capacities can be mixed provided other memory population rules are followed.

For example, 8 GB and 16 GB memory modules can be mixed.

• In a dual-processor configuration, the memory configuration for each processor must be identical.

For example, if you populate socket A1 for processor 1, then populate socket B1 for processor 2, and so on.

• Mixing of more than two memory module capacities in a system is not supported.

• Unbalanced memory configurations will result in a performance loss so always populate memory channels identically with identical

DIMMs for best performance.

• Populate six identical memory modules per processor (one DIMM per channel) at a time to maximize performance.

DIMM population update for Performance Optimized mode with quantity of 4 and 8 DIMMs per processor.

• When the DIMM quantity is 4 per processor, the population is slot 1, 2, 4, 5.

• When the DIMM quantity is 8 per processor, the population is slot 1, 2, 4, 5, 7, 8, 10, 11.

NVDIMM-N memory module installation guidelines

The following are the recommended guidelines for installing NVDIMM-N memory modules:

• Each system supports memory configurations with 1, 2, 4, 6, or 12 NVDIMM-Ns.

• Supported configurations have dual processors and a minimum of 12x RDIMMs.

• Maximum of 12 NVDIMM-Ns can be installed in a system.

• NVDIMM-Ns or RDIMMs must not be mixed with LRDIMMs.

• DDR4 NVDIMM-Ns must be populated only on the black release tabs on processor 1 and 2.

• For systems with four processors, RDIMMs populated on processor 3 and 4 must be identical to the number of RDIMMs populated on

processor 1 and 2.

• All slots on configurations 3, 6, 9, and 12 can be used, but a maximum of 12 NVDIMM-Ns can be installed in a system.

NOTE: NVDIMM-N memory slots are not hot-pluggable.

For more information about the supported NVDIMM-N configurations, see the NVDIMM-N User Guide at www.dell.com/

DCPMM installation guidelines

The following are the recommended guidelines for installing data center persistent memory module (DCPMM) memory modules:

• Each system supports maximum of one DCPMM memory module per channel.

NOTE: If two different DCPMM capacities are mixed, an F1/F2 warning is displayed as the configuration is not

supported.

• DCPMM can be mixed with RDIMM, LRDIMM, and 3DS LRDIMM.

• Mixing of DDR4 DIMM types (RDIMM, LRDIMM, and 3DS LRDIMM), within channels, for Integrated Memory Controller (iMC), or

across sockets are not supported.

94 Installing and removing system components

• Mixing of DCPMM operating modes (App Direct, Memory Mode) is not supported.

• If only one DIMM is populated on a channel, it should always go to the first slot in that channel (white slot).

• If a DCPMM and a DDR4 DIMM are populated on the same channel, always plug DCPMM on second slot (black slot).

• If the DCPMM is configured in Memory Mode, the recommended DDR4 to DCPMM capacity ratio is 1:4 to 1:16 per iMC.

• DCPMMs' cannot be mixed with other DCPMMs capacities or NVDIMMs.

• Mixing different capacities of RDIMMs and LRDIMMs are not allowed when DCPMM is installed.

• DCPMMs of different capacities are not allowed.

For more information about the supported DCPMM configurations, see the Dell EMC DCPMM User 's Guide at https://www.dell.com/

NOTE: There are limited configurations available for Dual Socket Servers with only one CPU populated.

NOTE: DCPMM is supported on systems with 1600W and 2400W PSU configuration.

NOTE:

• High Performance Fan is required with DCPMM.

• GPU and FGPA cards are not supported.

• Mid or rear storage is not supported.

• Front 12 x 3.5-inch drives are not supported.

Mode-specific guidelines

The configurations allowed depend on the memory mode selected in the System BIOS.

Table 54. Memory operating modes

Memory Operating Mode Description

Optimizer Mode The Optimizer Mode if enabled, the DRAM controllers operate

independently in the 64-bit mode and provide optimized memory

performance.

NOTE: DCPMM supports only Optimizer mode.

Mirror Mode The Mirror Mode if enabled, the system maintains two identical

copies of data in memory, and the total available system memory is

one half of the total installed physical memory. Half of the installed

memory is used to mirror the active memory modules. This feature

provides maximum reliability and enables the system to continue

running even during a catastrophic memory failure by switching

over to the mirrored copy. The installation guidelines to enable

96 Installing and removing system components

Table 54. Memory operating modes (continued)

Memory Operating Mode Description

Mirror Mode require that the memory modules be identical in size,

speed, and technology, and they must be populated in sets of 6 per

processor.

Single Rank Spare Mode Single Rank Spare Mode allocates one rank per channel as a

spare. If excessive correctable errors occur in a rank or channel,

while the operating system is running, they are moved to the spare

area to prevent errors from causing an uncorrectable failure.

Requires two or more ranks to be populated in each channel.

Multi Rank Spare Mode Multi Rank Spare Mode allocates two ranks per channel as a

spare. If excessive correctable errors occur in a rank or channel,

while the operating system is running, they are moved to the spare

area to prevent errors from causing an uncorrectable failure.

Requires three or more ranks to be populated in each channel.

With single rank memory sparing enabled, the system memory

available to the operating system is reduced by one rank per

channel.

For example, in a dual-processor configuration with 24x 16 GB

dual-rank memory modules, the available system memory is: 3/4

(ranks/channel) × 24 (memory modules) × 16 GB = 288 GB, and

not 24 (memory modules) × 16 GB = 384 GB. For multi rank

sparing, the multiplier changes to 1/2 (ranks/channel).

NOTE: To use memory sparing, this feature must be

enabled in the BIOS menu of System Setup.

NOTE: Memory sparing does not offer protection

against a multi-bit uncorrectable error.

Dell Fault Resilient Mode The Dell Fault Resilient Mode if enabled, the BIOS creates an

area of memory that is fault resilient. This mode can be used by an

OS that supports the feature to load critical applications or enables

the OS kernel to maximize system availability.

NOTE: This feature is only supported in Gold and

Platinum Intel processors.

NOTE: Memory configuration has to be of same size

DIMM, speed, and rank.

Optimizer Mode

This mode supports Single Device Data Correction (SDDC) only for memory modules that use x4 device width. It does not impose any

specific slot population requirements.

• Dual processor: Populate the slots in round robin sequence starting with processor 1.

NOTE: Processor 1 and processor 2 population should match.

• Quad processor: Populate the slots in round robin sequence starting with processor 1.

NOTE: Processor 1, processor 2, processor 3, and processor 4 population should match.

Power supply units

The power supply unit (PSU) is an internal hardware component which supplies power to the components in the system.

Your system supports one of the following:

• Two 2400 W, 2000 W, 1600 W, 1100 W, 750 W, or 495 W AC PSUs

• Two 1600 W, 1100 W, 750 W, 750 W Mixed Mode, or 495 W AC PSUs

• Two 1100 W DC PSUs

• Two 1100 W or 750 W Mixed Mode HVDC PSUs

NOTE: For more information, see the Technical specifications section.

CAUTION: If two PSUs are installed, both the PSUs must have the same type of label. For example, Extended Power

Performance (EPP) label. Mixing PSUs from previous generations of PowerEdge servers is not supported, even if the

PSUs have the same power rating. Mixing PSUs will result in mismatch condition or failure to turn the system on.

NOTE: Titanium PSU is nominally rated for 200 V AC to 240 V AC input only.

NOTE: When two identical PSUs are installed, power supply redundancy (1+1 – with redundancy or 2+0 – without

redundancy) is configured in system BIOS. In redundant mode, power is supplied to the system equally from both PSUs

when Hot Spare is disabled. When Hot Spare is enabled, one of the PSUs is put into the sleep mode when system

utilization is low in order to maximize efficiency.

NOTE: If two PSUs are used, they must be of the same maximum output power.

This section contains information about the hot spare features, wiring instructions for a DC power supply unit, removal and installation of

the power supply blank, and AC power supply unit.

152 Installing and removing system components

Hot spare feature

Your system supports the hot spare feature that significantly reduces the power overhead associated with power supply unit (PSU)

redundancy.

When the hot spare feature is enabled, one of the redundant PSUs is switched to the sleep state. The active PSU supports 100 percent of

the system load, thus operating at higher efficiency. The PSU in the sleep state monitors output voltage of the active PSU. If the output

voltage of the active PSU drops, the PSU in the sleep state returns to an active output state.

If having both PSUs active is more efficient than having one PSU in the sleep state, the active PSU can also activate the sleeping PSU.

The default PSU settings are as follows:

• If the load on the active PSU is more than 50 percent of PSU rated power wattage, then the redundant PSU is switched to the active

state.

• If the load on the active PSU falls below 20 percent of PSU rated power wattage, then the redundant PSU is switched to the sleep

state.

You can configure the hot spare feature by using the iDRAC settings. www.dell.com/poweredgemanuals.
