If you are installing an optional device in the server, you need to slide the server out from the rack enclosure,
turn off the server and peripheral devices, and disconnect the power cords and all external cables.
To install an adapter, complete the following steps.
Step 1. Remove the cover (see "Removing the cover" on page 33).
Step 2. Remove the PCI riser-card assembly (see "Removing the PCI riser-card assembly" on page 163).
Step 3. Touch the static-protective package that contains the adapter to any unpainted metal surface on
the server; then, remove the adapter from the package.
Step 4. Place the adapter, component side up, on a flat, static-protective surface and set any jumpers or
switches as described by the adapter manufacturer, if necessary.
Step 5. Remove the expansion-slot filler from the PCI riser-card assembly and save for future use.
Step 6. Align the gold finger on the adapter with the connector on the PCI riser-card assembly, then, insert
the adapter into the PCI riser-card assembly. Press the edge of the connector firmly into the PCI
riser-card assembly. Make sure that the adapter is securely installed in the PCI riser-card assembly.
Important: Make sure that the U-shaped opening in the metal adapter bracket engages the tab
on the expansion-slot filler.
