This topic provides instructions on how to remove an Ethernet card.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• Depending on the specific type, the Ethernet card might look different from the illustration in this topic.
• Use any documentation that comes with the Ethernet card and follow those instructions in addition to
the instructions in this topic.
To remove an Ethernet card, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.
2. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface. See the Rack Installation Instructions that comes with the server.
3. Remove the server cover. See "Removing the server cover" on page 85.
4. Remove the riser card assembly 2 and lay it upside down on a flat, clean, and static-protective surface.
See "Replacing the riser card assembly 2" on page 165.
Note: Usually Ethernet cards are installed on the riser card assembly 2. An Ethernet card also might
be installed in any PCI Express card slot that supports it. See "Rear view of the server" on page 26 to
identify the PCI Express card slots of your server.
5. Locate the Ethernet card you want to remove. Then, grasp the Ethernet card by its edges and carefully
pull it out of the PCI Express card slot on the riser card assembly.
Note: The Ethernet card might fit tightly into the PCI Express card slot. If necessary, alternate moving
each side of the Ethernet card a small and equal amount until it is completely removed from the slot.
