Expansion Cards
The system supports up to two PCI expansion cards, which are installed in connectors on a riser board. The upper slot supports PCI 32-bit, 33-MHz (5.0 V)
expansion cards and the lower slot supports PCI-X 64-bit, 66-MHz (3.3 V) expansion cards. See

. If you are installing a remote access controller card,
it must be installed in the upper slot of the riser board. Install most RAID controller cards and SCSI controllers in the lower slot.

CAUTION:
See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting
against electrostatic discharge.
NOTE:
Keep this bracket if you need to remove the expansion card. Filler brackets must be installed over empty expansion card slots to maintain
Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of the system and aid in proper
cooling and airflow inside the system.
NOTE:
Ensure that the expansion-card bracket is also inserted into the securing slot on the chassis's back panel.
