15. Wait for the power LED to stop blinking. The PCI/PCI-X card is now active. 16. Reconnect all cables. 17. Replace the top cover. (See "Replacing the Top Cover" (page 66).) 18. Push the server all the way back into the rack until it stops. Understanding LEDs and Hardware Errors Table 3-12 describes the hot-pluggable LED error conditions. Table 3-12 Hot-Pluggable LED Error Conditions Power LED (Green) Attention LED (Amber) Condition On Blinking Off Condition On Description PCI/PCI-X slot is powered on Hot-pluggable operation in progress. Do not touch the slot PCI/PCI-X slot is powered off Description Hardware operational fault NOTE: If the slot is powered on, it does not power off. If the slot is powered off, it does not power on Blinking Off Slot location is being indicated If power to the slot is on, the slot is functioning normally Troubleshooting PCI/PCI-X Hot-Pluggable Operations Sometimes a PCI/PCI-X card does not come online during a hot-pluggable operation due to a frequency mismatch between the PCI/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 described as follows: 1. PCI/PCI-X bus mode or frequency mismatch After you insert a PCI/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. The system firmware has rejected the PCI/PCI-X card and indicates either bus-frequency or bus-mode mismatch. After pushing the attention button, wait for the full five second operation cancellation window before taking further action. 2. Hardware operation fault If the PCI/PCI-X card cannot be powered on during a hot-pluggable addition operation, the attention LED turns steady on and the power LED goes steady off. 3. Power draw is excessive If the power draw for a 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 server. 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. Determine whether the card is in use by checking the operating system logs. 4. Slot does not power off If the slot does not power off during a hot-plug removal operation, do not open the MRL on the OLX divider. This action causes system failure or operating system crashes. 96 Installing the System

Troubleshooting PCI/PCI-X Hot-Pluggable Operations
Sometimes a PCI/PCI-X card does not come online during a hot-pluggable operation due to a
frequency mismatch between the PCI/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 described
as follows:
1.
PCI/PCI-X bus mode or frequency mismatch
After you insert a PCI/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. The system firmware has
rejected the PCI/PCI-X card and indicates either bus-frequency or bus-mode mismatch.
After pushing the attention button, wait for the full five second operation cancellation
window before taking further action.
2.
Hardware operation fault
If the PCI/PCI-X card cannot be powered on during a hot-pluggable addition operation, the
attention LED turns steady on and the power LED goes steady off.
3.
Power draw is excessive
If the power draw for a 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 server.
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. Determine whether the card is in use by checking the operating system logs.
4.
Slot does not power off
If the slot does not power off during a hot-plug removal operation, do not open the MRL
on the OLX divider. This action causes system failure or operating system crashes.
