Dell 1900 owner manual Removing the Cooling Shroud

Cooling Shroud

The cooling shroud produces and directs airflow over the system memory modules with an attached hot- plug fan. The fan need not be removed prior to removing the shroud.

Removing the Cooling Shroud

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.

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

NOTICE: Never remove the memory cooling shroud without first powering down the system. Overheating of the system can develop quickly resulting in a shutdown of the system and the loss of data.

2Open the system. See "Opening the System" on page 48.

3To remove the cooling shroud, release the blue latches on the shroud by pulling each latch outward from its securing tab. See Figure 3-19.

4Lift the shroud straight up to disengage the fan connector from the system board, and then lift the shroud out of the system. See Figure 3-19.

CAUTION: The DIMMs are hot to the touch for some time after the system has been powered down. Allow time for the DIMMs to cool before handling them. Handle the DIMMs by the card edges and avoid touching the DIMM components.
