NOTE After pushing the attention button, ensure that you wait the full five second operation
cancellation window before taking further action.
Hardware Operation Fault
A hardware operation fault is usually caused by an incorrectly seated or defective PCI/PCI-X card. If this
occurs, the attention LED turns steady on and the power LED turns steady off.
CAUTION If the power draw for the newly installed PCI/PCI-X card is excessive when combined with that
of the existing PCI/PCI-X expansion cards, the server powers off. If this occurs, check the power
ratings of all installed PCI/PCI-X cards. A known cause of power loss is the use of more than
three PCI/PCI-X RAID cards in the system.
If the PCI/PCI-X card cannot be powered off during a hot-pluggable removal operation, the attention button
turns steady on and the power LED remains steady-on. A possible cause of this condition is that a user
application or process is using the card you are trying to remove. You can determine if the card is in use by
checking the operating system logs.
CAUTION If your slot does not power off during a hot-pluggable removal operation, do not open the
manual retention latch (MRL) on the OLX divider. This action causes system failure or
operating system crashes.
Troubleshooting Using LED Indicators
The HP 9000 rp4410 and rp4440 servers have LED indicators located on the front control panel and an
internal QuickFind diagnostic panel that you can use to determine what repair action is required.
Front Control Panel LEDs
The front control panel LEDs display the system status at a glance. If warning or attention LEDs are
flashing, query the QuickFind diagnostic panel or iLO MP for further information.
