Attention:
When you handle static-sensitive devices, take precautions to avoid
damage from static electricity. For details about handling these devices, see
"Handling static-sensitive devices" on page 12.
1. Read the safety information beginning on page v and "Installation guidelines" on
page 11.
2. Disable the PCI-X slot through your operating system before you insert or
remove a PCI or PCI-X adapter.
Note: Some operating systems do not support the enabling and disabling of a
PCI-X slot. If your operating system does not support this function, turn
off the server and peripheral devices, and disconnect the power cords
and all external devices from the back of the server before proceeding.
3. Open the top cover.
4. Follow the cabling instructions, if any, that come with the adapter. Route the
adapter cables before you install the adapter.
