Troubleshooting PCI/PCI-X Hot-Pluggable Operations
Sometimes a PCI/PCI-X card does not come online during hot-plugging 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, interpret the LED display described as follows.
Figure 5-1 shows the PCI/PCI-X LEDs.

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. This means that the system firmware has rejected the
PCI/PCI-X card and indicates either bus-frequency or bus-mode mismatch.
