an indicator. The indicator shows whether power is present or a power fault has occurred.
Figure 14. AC PSU status indicator
1. AC PSU status indicator/handle
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 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.

Your system contains 32 memory sockets split into two sets of 16 sockets, one set per processor. Each 16-socket set is organized into
eight channels. In each channel, the release tabs of the first socket are marked white, and the second socket black.
NOTE: For optimal performance, it is recommended to populate one DIMM per channel with DDR4, 2666 MT/s memory
modules on the first slot of each memory channel. The first slot of each channel can be identified as the DIMM slots
with white latches. For example, 64 GB system memory capacity can be divided into 8 x 8 GB DIMM slots.

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 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])
108 PowerEdge R740xd installing and removing system components
• 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.
• 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 A16 are available.
• For dual-processor systems, sockets A1 to A16 and sockets B1 to B16 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 eight identical memory modules per processor (one DIMM per channel) at a time to maximize performance.
• To ensure proper cooling in the system with mid-backplane, memory module blanks must be installed in memory sockets that are not
occupied.
Mode-specific guidelines
The configurations allowed depend on the memory mode selected in the System BIOS.
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.
NOTE:
• Normal DIMM population rule:
• Single processor systems: Slot 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
• DIMM population changed when Performance Optimized Mode is ordered and there is a quantity of 4 or 8 DIMMs per
processor.
• With DIMM quantity of 4, the population with 1 processor is slot 1, 3, 5, 7
• Dual processor system: Processor 2 population must match Processor 1 population.
• With DIMM quantity of 8, the population with 1 processor is slot 1, 2, 3, 4, 5, 6, 7, 8
• Dual processor system: Processor 2 population must match Processor 1 population.

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 1100 W DC PSUs
• Two 1100 W, 750 W Mixed Mode HVDC (for China only) PSUs
• Two 750 W Mixed Mode AC, DC (DC for China only) 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 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 to maximize efficiency.
NOTE: If two PSUs are used, they must be of the same maximum output power.
178 PowerEdge R740xd 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 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, then the redundant PSU is switched to the active state.
• If the load on the active PSU falls below 20 percent, 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 about iDRAC settings, see the Integrated Dell
Remote Access Controller User’s Guide available at www.dell.com/idracmanuals.
Removing a power supply unit blank
Prerequisites

CAUTION: When connecting the power cable to the PSU, secure the cable to the PSU with the strap.
NOTE: When installing, hot swapping, or hot adding a new PSU, wait for 15 seconds for the system to recognize the
PSU and determine its status. The PSU redundancy may not occur until discovery is complete. Wait until the new
PSU is discovered and enabled before you remove the other PSU. The PSU status indicator turns green to signify
that the PSU is functioning properly.
Wiring instructions for a DC power supply unit
Your system supports up to two –(48–60) V DC power supply units (PSUs).
NOTE: For equipment using –(48–60) V DC power supply units (PSUs), a qualified electrician must perform all
connections to DC power and to safety grounds. Do not attempt connecting to DC power or installing grounds yourself.
All electrical wiring must comply with applicable local or national codes and practices. Damage due to servicing that is
not authorized by Dell is not covered by your warranty. Read and follow all safety instructions that came with the
