Dell PowerEdge 650 - Manual (Page 49)

Installing a Fan Assembly
1. Align the replacement fan assembly's connector with the connector on the system board and the pegs on the chassis. See Figure 6 -2 , Figure 6 -3 , and
Figure 6 -4 for the locations of the fan assemblies.
2. Push down on the fan assembly until it is properly seated on the chassis pegs and to the three-pin connector on the system board.
If you are installing the processor fan assembly, install the two cooling shrouds after installing the processor fan assembly. See Figure 6 -1 for the
location of the cooling shrouds.
3. Close the system. See " Closing the System " in "Troubleshooting Your System."
Expansion Cards
The system supports up to two PCI expansion cards, which are installed in connectors on a riser board. The upper slot supports 64-bit, 33-MHz cards and the
lower slot supports 64-bit, 133-MHz cards. See
Figure A -5 . 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.
Installing an Expansion Card
1. Open the system. See " Opening the System " in Troubleshooting Your System."
2. Remove the expansion-card retainer adjacent to the PCI slots.
3. Remove the filler bracket on the slot you will be using.
4. Insert the expansion card firmly into the expansion-card connector on the riser board until the card is fully seated, being careful not to remove the riser
card from the system board.
If you are installing a SCSI or RAID controller card, route the interface cable through the openings in the backplane bracket and the PCI fan bracket
before connecting the cable to the controller card. After routing the interface cable, ensure that the cable is securely connected to the controller card and
the hard drives.
5. Replace the expansion-card retainer. See Figure 6 -5 .
6. Connect any external cable(s) to the expansion card.
7. Close the system. See " Closing the System " in "Troubleshooting Your System."
Figure 6-5. Installing an Expansion Card
NOTE: Keep this bracket in the event 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.
