Table 12. 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.

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. 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.

CAUTION: 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.

CAUTION: If two PSUs are used, they must be of the same type and have the same

maximum output power.

CAUTION: Combining AC and DC PSUs is not supported and triggers a mismatch.

The cooling fans are integrated into the system to dissipate the heat generated by the functioning of the system. These fans

provide cooling for the processors, expansion cards, and memory modules.

Your system supports up to six standard or high performance hot swappable cooling fans.

For single processor systems, only four standard cooling fans are required. Fan bays one and two are covered by a fan blank.

CAUTION: Mixing of standard and high performance cooling fans is not supported.

NOTE: Each fan is listed in the systems management software, referenced by the respective fan number. If there is a

problem with a particular fan, you can easily identify and replace the proper fan by noting the fan numbers on the cooling

fan assembly.

NOTE: Cooling fans are hot swappable.

System memory

System memory guidelines

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

(NVDIMM-Ns), and DCPMM. 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 frequencies 2933 MT/s, 2666 MT/s, 2400 MT/s, or 2133 MT/s depending on the following

factors:

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

62 Installing and removing system components

●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.

NOTE: 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.

NOTE: 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.

NOTE: 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 one 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/

PMem installation guidelines

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

●Each system supports maximum of one PMem memory module per channel.

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

66 Installing and removing system components

●PMem 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.

●Mixing of PMem 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 PMem and a DDR4 DIMM are populated on the same channel, always plug PMem on second slot (black slot).

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

●PMems' cannot be mixed with other PMems capacities or NVDIMMs.

●Mixing different capacities of RDIMMs and LRDIMMs are not allowed when PMem is installed.

●PMems of different capacities are not allowed.

For more information about the supported PMem configurations, see the Dell EMC PMem User 's Guide at https://

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

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

NOTE:

●High Performance Fan is required with PMem.

●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 23. 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: PMem 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

68 Installing and removing system components

Table 23. Memory operating modes (continued)

Memory Operating Mode Description

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 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.

Installing a processor and heat sink module

Prerequisites

CAUTION: Never remove the heat sink from a processor unless you intend to replace the processor. The heat

sink is necessary to maintain proper thermal conditions.

WARNING: The heat sink may be hot to touch for some time after the system has been powered down. Allow the

heat sink to cool before removing it.

1. Follow the safety guidelines listed in Safety instructions.

2. If installed, remove the processor blank and CPU dust cover.

The procedure to remove the processor/DIMM blank is similar to that of the memory module.

Steps

1. Align the pin 1 indicator of the heat sink to the system board and then place the processor and heat sink module (PHM) on

the processor socket.

CAUTION: To avoid damaging the fins on the heat sink, do not press down on the heat sink fins.

NOTE: Ensure that the PHM is held parallel to the system board to prevent damaging the components.

2. Push the blue retention clips inward to allow the heat sink to drop into place.

3. Using the Torx #T30 screwdriver, tighten the screws on the heat sink in the order below:

a. Partially tighten the first screw (approximately 3 turns).

b. Tighten the second screw completely.

Installing and removing system components 77

c. Return to the first screw and tighten it completely.

If the PHM slips off the blue retention clips when the screws are partially tightened, follow these steps to secure the PHM:

a. Loosen both the heat sink screws completely.

b. Lower the PHM on to the blue retention clips, following the procedure described in step 2.

c. Secure the PHM to the system board, following the replacement instructions listed in this step above. 4.

NOTE: The processor and heat sink module retention screws should not be tightened to more than 0.13 kgf-m (1.35

N.m or 12 in-lbf).

Power supply units

Power supply unit details

Your system supports one of the following:

●Two 2400 W, 2000 W, 1600 W, 1100 W, 750 W, 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 www.dell.com/poweredgemanuals section.

130 Installing and removing system components

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.

NOTE: PSUs are hot swappable.

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. For more information, see the iDRAC User’s Guide

available at www.dell.com/poweredgemanuals.
