Dell PowerEdge 2600 - Manual (Page 51)

To take advantage of future options in speed and functionality, you can add a second microprocessor or replace either the primary or secondary
microprocessor.
Each microprocessor and its associated cache memory are contained in a PGA package that is installed in a ZIF socket on the system board. A second ZIF
socket accommodates a secondary microprocessor.

Removing and Replacing a Microprocessor
1. Open the bezel (see " Removing the Bezel ").
2. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
3. Remove the cover (see " Removing the Cover ").
4. Remove the cooling shroud (see " Removing the Cooling Shroud ").
5. Remove the back fan assembly (see " Removing the Back Fan Assembly "). If you are installing a second microprocessor, go to step 9.
6. Remove the microprocessor heat sink:
a. Press down on the heat-sink securing clips to release the clips from the retaining tabs on the ZIF socket (see Figure 4 -31 ).
b. Remove the heat-sink securing clips.
c. Lift the heat sink out of the chassis and place it on its side.
Figure 4-31. Removing and Replacing a Heat Sink
7. Pull the socket release lever straight up until the microprocessor is released (see Figure 4 -32 ).
NOTE: The second microprocessor must be of the same type as the first. If the two microprocessors are different speeds, both will operate at the
speed of the slower microprocessor.
NOTE: In a single microprocessor system, the microprocessor must be installed in the PROC 1 socket.
CAUTION: Before you perform this procedure, you must turn off the system and disconnect it from its power source. For more information, see
the safety instructions in your System Information Guide.
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See
your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against
electrostatic discharge.
CAUTION: The microprocessor and heat sink can become extremely hot. Be sure the microprocessor has had sufficient time to cool before
handling.
NOTICE: Never remove the heat sink from a microprocessor unless you intend to remove the microprocessor. The heat sink is required to maintain
proper thermal conditions.
