Removing the PCI riser-card assembly
To remove the PCI riser-card assembly, complete the following steps:
1. Read the safety information that begins on page “Safety” on page vii and the
“Installation guidelines” on page 25.
2. Turn off the server and peripheral devices and disconnect the power cords and
all external cables.
Note: When you disconnect the power source from the server, you lose the
ability to view the LEDs because the LEDs are not lit when the power
source is removed. Before you disconnect the power source, make a
note of which LEDs are lit; then, see the
Problem Determination and
Service Guide for information about how to solve the problem.
3. Remove the server top cover (see “Removing the server top cover” on page
27).
4. If an adapter is installed in the PCI riser-card assembly, disconnect any cables
that are connected to the adapter.
5. Grasp the front and rear of the PCI riser-card assembly and lift it out of the PCI
riser-card slot on the system board.
