Upgrading the Processor
It is possible to upgrade your processor to take advantage of future options in speed and functionality. Each processor and its associated Level 2 (L2) cache
memory are contained in a pin grid array (PGA) package that is installed in a ZIF socket on the system board.
The following items are included in the processor upgrade kit:
l Processor
l Heat sink
l Securing clip
Replacing the Processor
1. Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
2. Remove the system cover. See " Removing and Replacing the System Cover ."
3. Remove the cooling shroud.
4. Pushing down with one hand on the securing clip's rubber-coated tab, use the other hand to pull the latch on the securing clip on the left to release the
securing clip from the heat-sink posts. See Figure 5 -6 .
5. Remove the securing clip.
6. Repeat step 4 and step 5 to remove the securing clip on the right.
Figure 5-6. Removing the Securing Clip
7. Remove the heat sink.
8. Pull the socket release lever straight up until the processor is released from the socket. See Figure 5 -7 .
9. Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new processor.
NOTE: When you turn on the system, press the power button for less than two seconds. If you press the power button for longer than 3 seconds,
the NAS system shuts down and automatically rebuilds its RAID arrays, which could impact system performance for several hours.
CAUTION: See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting
against electrostatic discharge.
NOTE: Dell recommends that only a technically knowledgeable person perform this procedure.
NOTICE: The processor and heat sink can become extremely hot. Be sure the processor has had sufficient time to cool before handling.
NOTICE: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper
thermal conditions.
NOTICE: Be careful not to bend any of the pins when removing the processor. Bending the pins can permanently damage the processor.
