Dell PowerVault NX3500 - Manual (Page 62)

62 Installing System Components
11 Close the system. See "Closing the System" on page 53.
12 Reconnect the system to its electrical outlet and turn the system on,
including any attached peripherals.
Cooling Shroud
The system board shroud covers the processor, heat sink, and memory
modules, and provides air flow to these components. Airflow is facilitated by
the cooling fan modules, which are positioned directly beneath the cooling
shroud. The power distribution board shroud covers the power distribution
board behind the power supply bay.
Removing the Cooling Shroud
WARNING: The memory modules and heat sink can get very hot during normal
operation. Ensure that the memory modules and heat sink have had sufficient time
to cool before you touch it.
CAUTION: Many repairs may only be done by a certified service technician.
You should only perform troubleshooting and simple repairs as authorized in
your product documentation, or as directed by the online or telephone service
and support team. Damage due to servicing that is not authorized by Dell is not
covered by your warranty. Read and follow the safety instructions that came
with the product.
CAUTION: Never operate your system with the cooling shroud removed. The system
may get overheated quickly, resulting in shutdown of the system and loss of data.
1 Turn off the system, including any attached peripherals, and disconnect
the system from the electrical outlet.
2 Open the system. See "Opening and Closing the System" on page 52.
3 Remove the SAS backplane cables routed over the shroud from the
system board.
4 Hold the touch points and gently lift the shroud straight up and away from
the system board. See Figure 2-8.
