Replacing the heat sink
Attention: Do not open your server or attempt any repair before reading and understanding "Safety information"
on page iii and "Guidelines" on page 63.
The heat sink might be very hot. Turn off the server and wait several minutes to let the server cool
before removing the server cover.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
• Depending on the model, your server might look slightly different from the illustrations in this topic.
• Use any documentation that comes with the new heat sink and follow those instructions in addition to
the instructions in this topic.
To replace the heat sink, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.
2. If the server is installed in a rack cabinet, remove the server from the rack cabinet and place it on a flat,
clean, and static-protective surface. See the Rack Installation Instructions that comes with the server. If
the server is in tower form factor, lay the server on its side for easier operation.
3. Remove the server cover. See "Removing the server cover" on page 66.
4. Remove the cooling shroud. See "Removing the cooling shroud" on page 69.
