If you have other devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 103.
Replacing a PCI riser-card assembly
Note: A PCI riser-card assembly must be installed in slot 2 even if you do not
install an adapter.
To replace a PCI riser-card assembly, complete the following steps:
1. Read the safety information that begins on page vii and the “Installation
guidelines” on page 44.
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, including the LEDs that are lit on the
operation information panel, on the light path diagnostics panel, and
LEDs inside the server on the system board; then, see the
Problem
Determination and Service Guide for information about how to solve the
problem.
3. Remove the cover (see “Removing the cover” on page 52).
4. If an adapter is installed in the riser-card assembly, disconnect any cables that
are connected to the adapter.
5. Grasp the rear of the riser-card assembly from the rear and lift it out of the PCI
riser-card slot on the system board.
