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.

Close the system. See "Closing the System" on page 71.
Cooling Shrouds
The system provides three cooling shrouds that direct airflow from the
cooling fans over the system processors (processor cooling shroud) and
memory modules (memory module cooling shrouds "A" and "B").
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 Memory Module Cooling Shrouds
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 71.
3
Squeeze the blue release latches located on top of the memory module
cooling shroud and lift the shroud out of the system. See Figure 3-15.
4
Repeat the previous step for the other memory module cooling shroud.
