Server Module Battery - Dell PowerEdge 1855 Installation And Troubleshooting Manual

If any of the pins on the processor appear bent, see
2. Align the pin-1 corner of the processor with the pin-1 corner of the ZIF socket. See Figure 6-19.
NOTE: Identifying the pin-1 corners is critical to positioning the processor correctly.
Identify the pin-1 corner of the processor by locating the tiny gold triangle on one corner of the processor. Place this corner in the same corner of the ZIF
socket identified by a corresponding triangle.
3. Install the processor in the socket.
NOTE: If you are installing just one processor, it must be installed in socket PROC_1. See Figure A-3.
NOTICE: Positioning the processor incorrectly can permanently damage the processor and the system when you turn it on. When placing the processor
in the socket, be sure that all of the pins on the processor enter the corresponding holes. Be careful not to bend the pins.
a. If the release lever on the processor socket is not positioned all the way up, move it to that position.
b. With the pin-1 corners of the processor and socket aligned, set the processor lightly in the socket, making sure all pins are matched with the
correct holes in the socket.
Because the system uses a ZIF processor socket, do not use force, which could bend the pins if the processor is misaligned.
When the processor is positioned correctly, it drops down into the socket with minimal pressure.
c. When the processor is fully seated in the socket, rotate the socket release lever back down until it snaps into place, securing the processor.
4. Install the heat sink:
a. Using a clean lint-free cloth, remove the existing thermal grease from the heat sink and the processor.
NOTE: Use the heat sink that you removed in
b. Apply thermal grease evenly to the top of the processor.
c. Place the heat sink onto the processor. See Figure 6-18.
d. Tighten the four screws to secure the heat sink to the server module board. See Figure 6-18.
5. Close the server module. See
6. Install the server module. See
As the system boots, it detects the presence of the new processor and automatically changes the system configuration information in the System Setup
program.
7. Press <F2> to enter the System Setup program, and check that the processor information matches the new system configuration.
See your User's Guide for instructions about using the System Setup program.
8. Run the system diagnostics to verify that the new processor operates correctly.
See "Running System Diagnostics" for information about running the diagnostics and troubleshooting processor problems.
