HBA.
2. Turn off the computer.
3. Disconnect the power cable.
4. Open and remove the computer cover and save the screws.
5. Locate the slot in which you will install the HBA, and remove the slot cover.
6. Place the HBA in the slot and press carefully until it is seated properly.
7. Secure the HBA to the chassis, following the server manufacturer’s instructions.
8. Connect the appropriate cable from the devices to the corresponding LC connector.
9. Close the computer cover. Insert and tighten the computer cover screws.
10. Plug in the power cable.
11. Turn on the computer and observe the monitor and the LED indicators to ensure proper
operation (see ”LED indicators” on page 14).
