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, PCI
cards, 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:
1. Use only parts provided by Lenovo.
2. 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 and PCI Express card slots
covered or occupied. When you install an internal drive or a PCI Express card, save the EMI shield or dummy
tray from the drive bay or save the PCI Express card slot bracket in case you later remove the device.
Attention: An unoccupied drive bay or PCI Express card slot 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 provides instructions on how to install or remove a memory module.
Note: The memory modules are sensitive to ESD. Ensure that you read and understand “Handling
static-sensitive devices” on page 66 first and carefully perform the operation.
Memory module installation rules
Your server has four memory slots to provide the following features:
• Each slot supports 2 GB, 4 GB, and 8 GB DDR3 unbuffered dual inline memory modules (UDIMMs) with
Error Checking and Correcting (ECC) technology.
• The minimum system memory is 2 GB (only one 2 GB memory module installed in the DIMM2 slot).
• The maximum system memory is 32 GB (one 8 GB memory module installed in each of the four 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 47.
