Dell R805 owner manual Removing the Memory Module Cooling Shrouds

5If 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.

6Close 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

1Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

2Open the system. See "Opening the System" on page 71.

3Squeeze 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.

4Repeat the previous step for the other memory module cooling shroud.
