IBM System x3550 M4 Type 7914: Installation and Service Guide
1. Read the safety information that begins on "Safety" on page vii and
"Installation guidelines" on page 33.
2. Turn off the server and peripheral devices and disconnect the power cords
and all external cables.
3. Remove the server cover (see "Removing the cover" on page 36).
4. Follow the cabling instructions, if any come with the adapter. Route the
adapter cables before you install the adapter.
5. Insert the adapter into the PCI riser-card assembly, aligning the edge
connector on the adapter with the connector on the PCI riser-card assembly.
Press the edge of the connector firmly into the PCI riser-card assembly. Make
sure that the adapter snaps into the PCI riser-card assembly securely.
Attention: When you install an adapter, make sure that the adapter is
correctly seated in the riser-card assembly and that the riser-card assembly is
securely seated in the riser-card connector on the system board before you
turn on the server. An incorrectly seated adapter might cause damage to the
system board, the riser-card assembly, or the adapter.
6. Install the PCI riser-card assembly in the server (see "Replacing a PCI
riser-card assembly" on page 245).
7. Connect the cable to the newly-installed adapter.
Note: You might need to remove the blue latch from PCI riser-card assembly
2 to easily connect the cables.
