Attention: For proper cooling and airflow, install the server cover before turning on the server. Operating the

To reinstall the server cover, see “Reinstalling the server cover and reconnecting cables” on page 106.
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
Express 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:
• 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 and PCI card slots covered
or occupied. When you install an internal drive or a PCI card, save the EMI shield or dummy tray from the
drive bay or save the PCI card slot bracket in case you later remove the device.
