Dell Poweredge R440 Parts Replacement Guide

Replacing Cabled Power Supply in Poweredge R440

Before beginning, be sure to review the safety instructions. After unpacking the new power supply unit (PSU), carefully slide the PSU into the PSU cage until it is fully seated. Use a Phillips #2 screwdriver to securely fasten the PSU to the system. Next, connect the PSU cables to the connectors on the system board. If necessary, install the expansion card riser, followed by the air shroud.

Replacing Cooling Fan in Poweredge R440

Begin by pressing the tabs on the side of the cable connector to detach the cable from the connector on the system board. If you have a 4x3.5-inch hard drive system, be sure to also disconnect the fan 1 cable from the power interposer board. Be sure to note the positioning of the cables as you remove them from the system board. Next, lift out the fan while holding the blue touch point. Now install the cooling fan, the internal riser, and the power cable to the system board. Ensure the cables are correctly routed before installing the air shroud.
Installing and upgrading Memory(RAM) in Poweredge R440
To guarantee optimal operation of your system, observe the following general rules when configuring your system memory. If the memory configurations of your system fail to abide by these rules, it may not boot, freeze during memory configuration, or function with reduced memory.
The speed of the memory bus may vary according to certain criteria:
• The system profile selected (such as Performance Optimized or Custom)
• The highest speed of DIMMs supported by the processor.
• The maximum speed of DIMMs supported.
(MT/s indicates the speed of DIMMs in MegaTransfers per second.)
The system supports Flexible Memory Configuration, enabling it to be configured and operated in any acceptable chipset structure. Here are the advised standards for installing memory modules:
• All DIMMs should be DDR4.
• RDIMMs and LRDIMMs should not be mixed.
• 64 GB DDP (Dual Die Package) LRDIMMs should not be combined with 128 GB TSV (Through Silicon Via/3DS) LRDIMMs.
• x4 and x8 DRAM-based memory modules can be combined.
• No more than two RDIMMs can be put in a single channel, no matter the rank count.
• No more than two LRDIMMs can be put in a single channel, regardless of rank count.
• A maximum of two distinct ranked DIMMs can be put in a single channel, no matter the rank count.
• If memory modules of different speeds are installed, they will operate at the speed of the slowest installed memory module(s).
• Only install memory modules if a processor is inserted.
– For single-processor systems, sockets A1 to A10 are usable.
– For dual-processor systems, sockets A1 to A10 and sockets B1 to B6 are available.
• Insert memory module sockets with white release tabs first, followed by black release tabs.
• When combining memory modules of different capacities, always put the sockets with memory modules of the highest capacity first.
For example, if you plan 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 combined as long as other rules of memory population are followed.
For example, 8 GB and 16 GB memory modules can be combined.
• In dual-processor configurations, the memory configurations for both processors should be the same.
For instance, if socket A1 is populated 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 accepted.
• Unbalanced memory configurations will cause a decrease in performance, so always put identical DIMMs in identical channels for optimum performance.
• For maximal performance, fill up six identical memory modules for every processor (one DIMM for every channel).
• To ensure sufficient system cooling, memory module blanks must be placed in empty memory sockets.
DIMM population update for Performance Optimized mode with a 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, 9, 10.
