Chapter 3: DXi6902 FRU Removal and Replacement Procedures
Replacing a Node Processor and Heatsink
Quantum DXi6902 User’s Guide 139
Caution: Positioning the processor incorrectly can permanently
damage the system board or the processor. Be careful
not to bend the pins in the socket.
Caution:
Do not use force to seat the processor. When the
processor is positioned correctly, it engages easily into
the socket.
2 With the release levers on the processor socket in the open position,
align pin 1 of the processor, using pin 1 position guide on the socket
as reference, and set the processor lightly in the socket.
3 Close the processor shield.
4 Rotate the socket release lever near the lock icon until it is locked in
position (see Figure 84 ).
5 Similarly, rotate the socket release lever near the unlock icon until it
is locked in position.
6 Using a clean lint-free cloth, remove the thermal grease from the
heatsink.
Caution: Applying too much thermal grease can result in excess
grease coming in contact with and contaminating the
processor socket.
7 Open the grease applicator included with your processor kit and
apply all of the thermal grease in the applicator to the center of the
topside of the new processor.
8 Place the heatsink on the processor (see Figure 83 ).
9 Using a #2 Phillips screwdriver, tighten the heatsink retention
sockets.
10 Close the Node cover (see Opening and Closing the Node ).
11 Turn on the system (see Turning On and Shutting Down the System
on page 21).
12 Run Factory Detect Hardware from the Service Menu to detect the
new hardware (see Factory Detect Hardware on page 40).
