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 eciency, 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 conguration to a low output conguration or vice versa, you must turn o the system.
CAUTION: The 120 V AC PSU is not recommended for this system and using the same can cause
system throttling.
CAUTION: If two PSUs are used, they must be of the same type and have the same maximum
output power.

System memory

The system supports DDR4 registered DIMM (RDIMMs) slots and load reduced DIMM (LRDIMMs) slots. 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 2667 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 prole 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.
Memory channels are organized as follows:

General memory module installation guidelines

NOTE: If your system's memory congurations fail to observe these guidelines, your system might not boot, might stop
responding during memory conguration, or might operate with reduced memory.
The system supports Flexible Memory Conguration, enabling the system to be congured and run in any valid chipset architectural conguration. 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-specic 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 dierent speeds are installed, they will operate at the speed of the slowest installed memory module(s) or
slower depending on the system DIMM conguration.
• Populate memory module sockets only if a processor is installed. 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 dierent 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 conguration, the memory conguration 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 dierent 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-specic guidelines
Six memory channels are allocated to each processor. The congurations 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 specic slot population requirements.
Memory sparing
: To use memory sparing, this feature must be enabled in BIOS menu of System Setup.
NOTE
Table 28. 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
Installing and removing system components 63
Page 64
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 conguration with twenty four 16 GB dual-rank memory modules, the available system memory is: 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 oer protection against a multi-bit uncorrectable error.
3/4 (ranks/
Memory mirroring
Memory mirroring oers the strongest memory module reliability mode, providing improved uncorrectable multi-bit failure protection. In a mirrored conguration, 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 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.
