4. Pull the system board tray straight back until it stops.
5. Lift the front of the system board tray upward slightly and then pull the tray straight back until it clears the chassis.
Replacing the System Board Tray
1. With the system board tray levers in the upright position, slide the tray into the chassis until it stops (see Figure 6 -6 ).
2. Rotate the system board tray levers down simultaneously until the tray is secured in the chassis (see Figure 6 -3 ).
3. Replace the cover (see " Replacing the Cover " in "Troubleshooting Your System").
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 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.
The following items are included in the microprocessor upgrade kit:
l A microprocessor
l A heat sink
l Two securing clips
l A cooling fan
l A VRM, if adding a second microprocessor
Adding or Replacing a Microprocessor
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Remove the cover (see " Removing the Cover " in "Troubleshooting Your System").
If you are installing a second microprocessor, go to step 6.
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
NOTICE: 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
" Safety First—For You and Your System " in "Troubleshooting Your System."
NOTICE: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
NOTE: The system is designed to allow you to remove the microprocessor heat sink without removing the microprocessor cooling fan. However,
you can remove the fan to provide easier access to the heat sink (see " Removing a Cooling Fan ").
