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.

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.

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.
106 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 57. 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
108 Installing and removing system components
Table 57. 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
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 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.
Installing and removing system components 171
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.
