Installing System Components 63
3
Connect the following power supply cables:
a
P3 to the hard drive cable harness
b
P2 to the system board connector 12V
c
P1 to the system board connector PWR_CONN
4
Close the system. See "Closing the System" on page47.
Expansion Cards
The system is available with an optional PCIe riser card or PCI-X/PCIe riser card. The PCIe riser card
contains two PCIe expansion slots with x8-lane connectors—slot 1 has x4-lane capability and slot 2 has
x8-lane capability. The PCI-X/PCIe riser card provides one PCI-X expansion slot and one PCIe x8-lane
expansion slot. If you are installing a remote access controller card, it must be installed in the upper slot
of a PCI-X/PCIe riser card. See "PCIe Riser Card Connectors" on page100 for the locations of the
expansion-card slots on the two types of riser cards.

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. Before performing any procedure, see your Product Information Guide for
complete information about safety precautions, working inside the computer and protecting against electrostatic
discharge.
1
Open the system. See "Opening the System" on page 46.
2
Remove the expansion-card retainer adjacent to the expansion card slots. See Figure3-14.
3
Slide the expansion-card sliding retainer to the retracted or open position. See Figure3-15.
4
Remove the filler bracket on the slot you will be using.
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.
5
Insert the expansion card firmly into the expansion-card connector on the riser card until the card is
fully seated.
NOTE: Ensure that the expansion-card bracket is also inserted into the securing slot on the chassis's back
panel.
6
Replace the expansion-card retainer. See Figure3-14.
7
Slide the expansion-card sliding retainer to the closed position so that it engages the edge of the
expansion card. See Figure3-15.
8
Connect any internal or external cable(s) to the expansion card.
NOTE: You may need to remove the riser card in order to install certain expansion cards with internal
connectors. See "Riser Card" on page66.

Close the system. See "Closing the System" on page47.
