Installing, removing, or replacing hardware
This topic provides instructions on how to install, remove, or replace hardware for your server. You can
expand the capabilities of your server by adding new hardware devices, such as memory modules or other
server options, and maintain your server by replacing the failing hardware devices.
If you are handling a server option, refer to the appropriate installation and or removal instructions in this
topic along with the instructions that come with the option.
Notes:
• Use only parts provided by Lenovo.
• Depending on the model, your server might look slightly different from the illustrations in this topic.
The EMI integrity and cooling of the server are protected by having all drive bays covered or occupied.
When you install an internal drive, save the EMI shield or dummy tray from the drive bay in the event that
you later remove the device.
Attention: An unoccupied drive bay without a cover, shield, dummy tray, filler, or any other protection might
impact the EMI integrity and cooling of the server, which might result in overheating or component damage.
Installing or removing a memory module
This topic contains the following items:
• “Memory module installation rules” on page 76
• “Installing a memory module” on page 81
• “Removing a memory module” on page 83
Note: The memory modules are sensitive to ESD. Ensure that you read and understand “Handling
static-sensitive devices” on page 64 first and carefully perform the operation.
Memory module installation rules
Your server has 16 memory slots and it has the following features:
• Each slot supports 32 GB double data rate 4 low-voltage registered dual inline memory modules (DDR4
LV RDIMMs).
• Each slot supports 4 GB, 8 GB, and 16 GB DDR4 RDIMMs.
• Your server supports up to eight memory modules when one microprocessor is installed and up to 16
memory modules when two microprocessors are installed.
• The minimum system memory for RDIMMs is 4 GB (only one microprocessor installed and only one 4
GB RDIMM installed in the CPU1 DIMMA1 slot).
• The minimum system memory for LV RDIMMs is 32 GB (only one microprocessor installed and only one
32 GB LV RDIMM installed in the CPU1 DIMMA1 slot).
• The maximum system memory for RDIMMs is 256 GB (two microprocessors installed and one 16 GB
RDIMM installed in each of the 16 memory slots).
• The maximum system memory for LV RDIMMs is 512 GB (two microprocessors installed and one 32 GB
LV RDIMM installed in each of the 16 memory slots).
For more information about the memory modules in your specific server model, use the Setup Utility
program. See “Viewing information in the Setup Utility program” on page 51.
