available:
• The PCIe riser has one x8-lane width PCIe expansion slot.
• The PCI-X riser has one 64-bit/133-MHz expansion slot.
Installing an Expansion Card
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the
components inside the system. See your Product Information Guide for complete information about safety
precautions, working inside the computer, and protecting against electrostatic discharge.

If you are adding a new card, open the expansion-card latch and remove the filler bracket. See
Figure 3-7.

Insert the card-edge connector firmly into the expansion-card connector until the card is fully
seated.
c
When the card is seated in the connector, close the expansion-card latch.
6
Connect any cables to the expansion card.
NOTICE: If you are installing a SAS RAID controller card, route the SAS cables though the oval opening in the
chassis brace and connect the cables to the SAS connectors on the hard drives. Secure the cables to the
clips on the edge of the cooling shroud.
See the documentation that came with the card for information about its cable connections.
