Using a #2 Phillips screwdriver, install the screw at the front of the power
supply that secures the power supply to the chassis.
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

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 page 124 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.
