Installing System Components
Removing 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.
1 Turn off the system, including any attached peripherals, and disconnect the system from the electrical
outlet.
2 Open the system. See "Opening the System" on page 55.
3 Disconnect all expansion-card cables.
4 Release the expansion card:
a Open the expansion-card latch. See Figure 3-14.
b Grasp the expansion card by its top corners, and carefully remove it from the expansion-card
connector.
5 If you are removing the card permanently, install a metal filler bracket over the empty expansion slot
opening and close the expansion-card latch.
NOTE:
You must install a filler bracket over an empty expansion slot to maintain Federal Communications
Commission (FCC) certification of the system. The brackets also aid in proper cooling and airflow inside the
system.
6 Reconnect all expansion-card cables.
7 Close the system. See "Closing the System" on page 56.
Cooling Shroud
The cooling shroud produces and directs airflow over the system processor(s) and memory modules.
CAUTION:
The DIMMs are hot to the touch for some time after the system has been powered down. Allow the
DIMMs to cool before handling them.
NOTICE:
Never operate your system with the memory cooling shroud removed. Overheating of the system can
develop quickly resulting in a shutdown of the system and the loss of data.
Removing the Cooling Shroud
1 Turn off the system, including any attached peripherals, and disconnect the system from the electrical
outlet.
2 Open the system. See "Opening the System" on page 55.
3 Remove the optical drive cable from the cable tabs on top of the cooling shroud.
4 Remove the expansion cards from the left expansion-card riser board.
5 Remove the left riser board. "Removing the Left Expansion-Card Riser Board" on page 102
6 Rotate the shroud upward and toward the front of the system on its hinges, and then lift the shroud
out of the system. See Figure 3-15.
