Step 8. Push the manual retention latch down until it seats against the chassis wall.
Step 9. Turn the PCI-X card lock on the chassis to the closed position. This locks the PCI-X card into its slot and the
manual retention latch into the closed position.
Step 10. Press the attention button—the power LED will start to blink.
Step 11. Wait for the power LED to stop blinking—the PCI-X card is now active.
Step 12. Replace the top cover.
Step 13. Push the HP Server all the way back into the rack until it stops.
Understanding LEDs and Hardware Errors
The following table describes the hot-plug LED error conditions.
Troubleshooting PCI-X Hot-Plug Operations
Sometimes a PCI-X card will not come online during a hot-plug operation due to a frequency mismatch between the PCI-X
card and the slot bus or due to other hardware errors. To determine the type of error you are experiencing, observe the LED
activity as described below. For a full understanding and description of HP-UX 11i v2 hardware errors, read Interface Card
OL* Support for HP-UX Servers and Workstations, Important Considerations, B2355-90804 at http://docs.hp.com.
1. PCI-X Bus Mode or Frequency Mismatch
After you insert a PCI-X card into the slot and push the attention button, the power LED goes from blinking to steady-off
and stays at steady-off; this means that the system firmware has rejected the PCI-X card, and indicates either bus
frequency or bus mode mismatch.
