Table 10. 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 rmware of the PSU is being updated, the PSU handle blinks green.
CAUTION: Do not disconnect the power cord or unplug the PSU when updating rmware. If
rmware update is interrupted, the PSUs do not function.
Blinking green and turns o When hot-plugging a PSU, the PSU handle blinks green ve times at a rate of 4 Hz and turns o. This
indicates a PSU mismatch with respect to eciency, 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 conguration to a low output conguration or
vice versa, you must turn o 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 dierent input voltages, they
can output dierent 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.

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 hot-plugging a PSU, the PSU indicator blinks green. This indicates that there is a PSU mismatch
with respect to eciency, 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 conguration to a Low Output
conguration or vice versa, you must turn o the system.
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.

Cooling fans
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 eight standard or high performance cooling fans.
NOTE:
• High performance fans can be identied by a blue label on top of the cooling fan.
• Mixing of standard and high performance cooling fans is not supported.
• Each fan is listed in the systems management software, referenced by the respective fan number. If there is a problem with a

System memory
The system supports DDR4 registered DIMM (RDIMMs) slots, load reduced DIMM (LRDIMMs) slots and non-volatile dual in-line DIMM-Ns
(NVDIMM-Ns). System memory holds the instructions that are executed by the processor.
NOTE: MT/s indicates DIMM speed in MegaTransfers per second.
Memory bus operating frequency can be 2666 MT/s, 2400 MT/s, or 2133 MT/s depending on the following factors:
• DIMM type (RDIMM or LRDIMM)
• Number of DIMM slots populated per channel
• System prole selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
• Maximum supported DIMM frequency of the processors
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. In each channel, the release tabs of the rst socket are marked white, and the second socket black.

General memory module installation guidelines
NOTE: If your system's memory congurations fail to observe these guidelines, your system might not boot, might stop
responding during memory conguration, or might operate with reduced memory.
The system supports Flexible Memory Conguration, enabling the system to be congured and run in any valid chipset architectural
conguration. The following are the recommended guidelines for installing memory modules:
• RDIMMs and LRDIMMs must not be mixed.
• x4 and x8 DRAM based memory modules can be mixed. For more information, see the Mode-specic guidelines section.
• 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.
• If memory modules with dierent speeds are installed, they will operate at the speed of the slowest installed memory module(s) or
slower depending on the system DIMM conguration.
• 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 rst, followed by the black release tabs.
• When mixing memory modules with dierent capacities, populate the sockets with memory modules with the highest capacity rst. 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.
• In a dual-processor conguration, the memory conguration for each processor should be identical. For example, if you populate socket
A1 for processor 1, then populate socket B1 for processor 2, and so on.
• Memory modules of dierent capacities can be mixed provided other memory population rules are followed (for example, 8 GB and 16
GB memory modules can be mixed).
• Mixing of more than two memory module capacities in a system is not supported.
• Populate six memory modules per processor (one DIMM per channel) at a time to maximize performance.
Mode-specic guidelines
Six memory channels are allocated to each processor. The congurations allowed depend on the memory mode selected.
Memory optimized (independent channel) mode
This mode supports Single Device Data Correction (SDDC) only for memory modules that use x4 device width. It does not impose any
specic slot population requirements.
Memory sparing
NOTE: To use memory sparing, this feature must be enabled in BIOS menu of System Setup.
Table 39. Memory sparing
Memory sparing (Single Rank) Memory sparing allocates one rank per channel as a spare. If
excessive correctable errors occur in a rank or channel, they are
moved to the spare area while the operating system is running to
prevent errors from causing an uncorrectable failure. Requires
population of two ranks or more per channel.
Memory sparing (Multi Rank) Memory sparing allocates two ranks per channel as a spare. If
excessive correctable errors occur in a rank or channel, they are
80 Installing and removing system components
moved to the spare area while the operating system is running to
prevent errors from causing an uncorrectable failure. Requires
population of three ranks or more per 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 conguration with twenty four 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. This calculation changes based on
if it is single rank sparing or multi rank sparing. For multi rank sparing, the multiplier changes to 1/2 (ranks/channel).
NOTE: Memory sparing does not oer protection against a multi-bit uncorrectable error.
Memory mirroring
Memory mirroring oers the strongest memory module reliability mode, providing improved uncorrectable multi-bit failure protection. In a
mirrored conguration, 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. In the event of an uncorrectable error, the system switches over to the mirrored copy. This
ensures Single Device Data Correction (SDDC) and multi-bit protection.
The installation guidelines for memory modules are as follows:
• Memory modules must be identical in size, speed, and technology.
• Memory modules must be populated in sets of 6 per CPU to enable memory mirroring.

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 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 specications 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.
142 Installing and removing system components
NOTE: When two identical PSUs are installed, power supply redundancy (1+1 – with redundancy or 2+0 – without redundancy) is
congured 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 eciency.
NOTE: If two PSUs are used, they must be of the same maximum output power.
Hot spare feature
Your system supports the hot spare feature that signicantly 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 eciency. 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 ecient 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 congure the hot spare feature by using the iDRAC settings. For more information, see the iDRAC User’s Guide available at
Dell.com/idracmanuals.

About this task
CAUTION: If you are using the Trusted Platform Module (TPM) with an encryption key, you may be prompted to create a
recovery key during program or System Setup. Work with the customer to create and safely store this recovery key. When
replacing this system board, you must supply the recovery key when you restart your system or program before you can access
the encrypted data on your hard drives.
CAUTION: Once the TPM plug-in module is installed, it is cryptographically bound to that specic system board. Any attempt to
remove an installed TPM plug-in module breaks the cryptographic binding, the removed TPM cannot be reinstalled or installed on
another system board.
