Configuring the Processor
NOTE: The procedures described in this document assume that the server
is out of the rack and is positioned on a flat, stable surface.
IMPORTANT: Observe the pre- and post-installation procedures described
in later sections when configuring the processor.
CAUTION: Follow the ESD precautions listed in Chapter 2 of the
HP ProLiant DL140 Generation 2 Server Maintenance and Service
Guide when handling the processor and heat sink. You can
download a copy of this guide from the HP website at
http://www.hp.com/.
WARNING: Failure to properly turn off the server before you
open the server may cause serious damage as well as
bodily harm.
WARNING: To reduce the risk of personal injury from hot
surfaces, allow the heat sink and the processor to cool before
touching them.
CAUTION: To prevent the heat sink from tilting to one side during
installation/removal procedures, observe a diagonally opposite
pattern (an “X” pattern) when loosening and tightening the four
spring-loaded screws.
Pre-installation Procedures
Perform the instructions below before removing or installing
a processor.
1. Turn off the server and all the peripherals connected to it.
2. Unplug all cables from the power outlets to avoid exposure to
high energy levels that may cause burns when parts are
short-circuited by metal objects such as tools or jewelry.
If necessary, label each one to expedite reassembly.
3. Disconnect telecommunication cables to avoid exposure to
shock hazard from ringing voltages.
4. Remove the top cover.
5. If necessary, remove any accessory boards or cables that
prevent access to the CPU sockets.
Removing the Processor
1. Perform the pre-installation procedures described in the
previous section.
2. Lift the air duct away from the CPU sockets.
Keep it for reinstallation later.
3. Locate the processor you want to remove.
4. Remove the heat sink:
a. Loosen the four spring-loaded screws a few threads out,
observing a diagonally opposite pattern, then loosen them
completely to release the heat sink from the processor base.
b. Lift the heat sink away from the system board.
5. Remove the processor:
a. Disengage the socket retention lever from the processor
base.
b. Grasp the processor by its edges and lift it out of its socket.
6. Place the processor on a static-dissipating work surface or
inside an anti-static bag.
Installing the Processor
1. Perform steps 1 and 2 of the “Removing the Processor” section.
2. Locate an empty processor socket.
3. Disengage the socket retention lever from the processor base.
4. Install the processor:
a. Hold the processor by its edges and align it over the empty
CPU socket.
Make sure that pin 1 of the processor (indicated by the gold
triangle on the corner) is properly aligned with hole 1 of the
socket (indicated by a notch). The pins are keyed in such a
way that you cannot install the processor in the wrong
orientation without bending the pins.
b. Insert the processor into the socket.
c. Engage the socket retention lever back into place.
