Dell PowerEdge 1750 - Manual (Page 51)

Installing Microprocessors
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 level 2 (L2) cache memory are contained in an FC-PGA2 package that is installed in a ZIF socket on the system board.
The secondary microprocessor must have the same operating frequency and cache size as the primary microprocessor.
The following items are included in the microprocessor upgrade kit:
l A microprocessor
l A heat sink
l Two retention clips
The following subsections describes how to remove and install a microprocessor in either the primary or secondary microprocessor connector.
Removing a Microprocessor
1. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.
2. Open the system covers. See " Opening the System Covers " in "Troubleshooting Your System."
3. To remove the two retention clips that secure the heat sink to the microprocessor socket at both ends, press down firmly on the release tab of each
retention clip until it disengages from the socket. See Figure 6 -6 .
Figure 6-6. Retention Clip
4. Remove the heat sink.
5. Remove the microprocessor from the socket by pulling the socket release lever straight up until the processor is released, and then lift the processor
out of the socket. See Figure 6 -7 .
If you are installing a new microprocessor, leave the release lever up so that the socket is ready for the new microprocessor.
Figure 6-7. Removing the Microprocessor
NOTICE: The second microprocessor must be of the same type and speed as the first microprocessor.
CAUTION: Ensure that you install only microprocessors purchased from Dell and intended for this system. Using a different microprocessor could
cause data loss, system damage, or personal injury.
CAUTION: Before you perform this procedure, you must turn off the system and disconnect it from its electrical outlet. For more information, see
" Safety First—For You and Your System " in "Troubleshooting Your System."
NOTICE: Never remove the heat sink from a microprocessor unless you intend to remove the microprocessor. The heat sink is necessary to maintain
proper thermal conditions.
CAUTION: The microprocessor chip and heat sink can become extremely hot. Be sure that the microprocessor has had sufficient time to cool
before handling.
NOTICE: Be careful not to bend any of the pins when removing the microprocessor. Bending the pins can permanently damage the microprocessor.
