Applying Power
To apply power:
1. Verify that the HBA is securely installed in the computer.
2. Verify that the correct media is attached.
3. Plug in the computer and turn it on.
4. Watch the LEDs for Power On Self Test (POST) results.
Viewing the LEDs
You can see green and yellow LEDs through openings in the HBA's mounting bracket. The green LED
means firmware operation and the yellow LED means port activity. Each port has a corresponding set of
green and yellow LEDs.
