Prerequisites
Before installing this option, be sure that you have the following:
• The components included with the hardware option kit
• A T-10 Torx screwdriver might be needed to unlock the access panel.
Procedure
1. Power down the server on page 32.
2. Remove all power:
a. Disconnect each power cord from the power source.
b. Disconnect each power cord from the server.
3. Do one of the following:
• Extend the server from the rack (Extending the server from the rack on page 32).
• Remove the server from the rack (Removing the server from the rack on page 33).
4. Remove the access panel (Removing the access panel on page 36).
CAUTION:
Do not operate the server for long periods with the access panel open or removed. Operating the
server in this manner results in improper airflow and improper cooling that can lead to thermal
damage.
5. Remove the primary PCIe riser cage (Removing a PCIe riser cage on page 39).
