Installing Additional Components and Configuring
Hot-Plug PCI-X
2. Hardware Operation Fault
If the PCI-X card cannot be powered on during a hot-plug addition operation, the attention LED will turn steady-on and
the power LED will go steady-off.
CAUTION If your card will not power up, the power loss may be due to the existing PCI-X expansion cards using all
the available power. Check the power ratings of your existing PCI-X cards. A known cause of power loss
is the use of more than 3 RAID cards in your system.
If the PCI-X card cannot be powered off during a hot-plug removal operation, the attention button will turn steady-on and
the power LED will remain steady-on.
CAUTION If your slot does not power off during a hot-plug removal operation, do not open the manual retention
latch (MRL) on the OLX divider. This action causes system failure or operating system crashes.
