Replacing a copper water loop
Use this information to replace a copper water loop.
Attention:
• Copper water loop supports Intel Xeon E5-2600 v3 and v4 series.
• Copper water loop is to be installed only by trained technicians.
• Make sure the water loop of the microprocessors are properly greased.
• The copper water loop FRU is packaged with the protective bracket on the top.
• If reusing the water loop apply new grease using the 9 dot method.
• Do not set down the water loop after you remove the four plastic covers.
• Do not touch the microprocessor contacts; handle the microprocessor by the edges only. Contaminants
on the microprocessor contacts, such as oil from your skin, can cause connection failures between the
contacts and the socket.
• The pins on the sockets are fragile. Any damage to the pins might require replacing the system board.
Read the safety information in Safety and Installation guidelines.
If you are replacing a server component in the water-cooled technology tray, you need to remove the water-
cooled technology tray from the chassis enclosure and refer to the "Removing a water-cooled technology
tray from a chassis" on page 139 and "Installing a water-cooled technology tray in a chassis" on page 140
sections.
To install a copper water loop, complete the following steps.
Step 1. Turn off the server and peripheral devices.
Attention: When you handle static-sensitive devices, take precautions to avoid damage from static
electricity.
Step 2. Remove the cover (see "Removing the cover" on page 142).
Step 3. If you are installing a new copper water loop, remove the plastic protective cover from the bottom
of the copper water loop.
Step 4. Align and place the copper water loop on the pocket of the wall which is parallel to the front side of
the planar tray.
