Appendix B: LED Decoder During the system boot process, the BIOS executes a number of platform configuration processes, each of which is assigned a specific hex POST code number. As each configuration routine is started, the BIOS displays the POST code to the POST Code Diagnostic LEDs on the back edge of the server board. To assist in troubleshooting a system hang during the POST process, you can use the Diagnostic LEDs to identify the last POST process that was executed. Each POST code is represented by the Eight amber Diagnostic LEDs. The POST codes are divided into two nibbles, an upper nibble and a lower nibble. The upper nibble bits are represented by Diagnostic LEDs #4, #5, #6, and #7. The lower nibble bits are represented by Diagnostics LEDs #0, #1, #2, and #3. Given the bit is set in the upper and lower nibbles, then corresponding LED is lit. If the bit is clear, corresponding LED is off. The Diagnostic LED #7 is labeled as "MSB", and the Diagnostic LED #0 is labeled with "LSB". Figure 21. Diagnostic LED Placement Diagram Table 6. Diagnostic LED Placement Diagram A. ID LED C.

Figure 7. Installing Memory	34
5. Make sure the clips at either end of the DIMM socket(s) are pushed outward to the open position (see letter “A” in Figure 7).	34
6. Holding the DIMM by the edges, remove it from its anti-static package.	34
7. Position the DIMM above the socket. Align the two small notches in the bottom edge of the DIMM with the keys in the socket (see letter “B” in Figure 7).	34
8. Insert the bottom edge of the DIMM into the socket (see letter “C” in Figure 7).	34
9. When the DIMM is inserted, push down on the top edge of the DIMM until the retaining clips snap into place (see letter “D” in Figure 7). Make sure the clips are firmly in place (see letter “E” in Figure 7).	34
10. Replace the server’s cover and reconnect the AC power cord.	34
Removing DIMMs	34

7. Reinstall and reconnect any parts you removed or disconnected to reach the DIMM sockets.	35
8. Replace the server's cover and reconnect the AC power cord.	35
Installing or Replacing the Processor	35
Note: Use the following instructions to install or replace a processor instead of using the instructions that came with the processor.	35
Caution: Processor must be appropriate: If you install a processor that is inappropriate for your server, you may damage the server board. See “Additional Information and Software” for a link to the list of compatible processor(s).	35
ESD and handling processors: Reduce the risk of electrostatic discharge (ESD) damage to the processor by doing the following: (1...	35
Installing the Processor	35
1. Observe the safety and ESD precautions at the beginning of this book. See “Safety Information” for more information.	35
2. Turn off all peripheral devices connected to the server and turn off the server.	35
3. Disconnect the AC power cord from the server.	35
4. Remove the server's cover. See the document that came with your server chassis for instructions on removing the server's cover.	35
5. Locate the processor socket and open the socket lever (see Figure 8).	35
Figure 8. Lifting the Load Lever	35
6. Open the load plate (see letter “A” in Figure 8 and letter “B” in Figure 9).	35
Figure 9. Open the Load Plate	36
7. Remove the socket protective cover (see Figure 10).	36
Figure 10. Remove the Socket Protective Cover	36
8. Take the processor out of the box and remove the protective shipping cover (Figure 11).	36
Figure 11. Remove the Processor Protective Cover	36
9. Align the processor cutouts to match the two socket pins, and then insert the processor into the socket as shown in Figure 12.	37
Figure 12. Installing the Processor	37
10. Close the load plate (see the letter “A” in Figure 13), close the socket lever and ensure the load plate tab engages under the socket lever when fully closed. (See letter “B” and “C” in Figure 13)	37
Figure 13. Close the Load Plate and Socket Lever	37
Note: Make sure the alignment triangle mark and the alignment triangle cutout align correctly. To assist in package orientation and alignment with the socket:	37
Installing the Retention Mechanism(s) and Heat Sink(s)	37
1. If a protective film covers the thermal interface material (TIM) on the underside of the heat sink, remove the protective film.	37
2. Align heat sink fins to the front and back of the chassis for correct airflow. Airflow goes from front-to-back of chassis.	37
3. Each heat sink has four captive fasteners and should be tightened as shown.	37
4. Using a #2 Phillips* screwdriver, finger-tighten each fastener diagonally according to the white-circled numbers (see Figure 14).	38
5. Securely re-tighten each fastener again in the same order as performed in Step 4.	38
6. Attach fan power cable to server board as shown.	38
Figure 14. 2U Reference Heat Sink Assembly	38
7. Reinstall and reconnect any parts you removed or disconnected to reach the processor sockets.	38
8. Replace the server's cover and reconnect the AC power cord. See the documentation that came with your server chassis for instructions on installing the server's cover.	38

7. Twist the heat sink slightly to break the seal between the heat sink and the processor.	39
8. Lift the heat sink from the processor. If it does not pull up easily, twist the heat sink again. Do not force the heat sink from the processor-doing so could damage the processor.	39
9. Lift the processor lever.	39
10. Raise the CPU load plate.	39
11. Remove the processor.	39
12. If installing a replacement processor, see “Installing the Processor”. Otherwise, install the protective socket cover over the empty processor socket and reinstall the chassis cover.	39

LED Decoder

During the system boot process, the BIOS executes a number of platform configuration

processes, each of which is assigned a specific hex POST code number. As each

configuration routine is started, the BIOS displays the POST code to the POST Code

Diagnostic LEDs on the back edge of the server board. To assist in troubleshooting a

system hang during the POST process, you can use the Diagnostic LEDs to identify the

last POST process that was executed.

Each POST code is represented by the Eight amber Diagnostic LEDs. The POST codes

are divided into two nibbles, an upper nibble and a lower nibble. The upper nibble bits are

represented by Diagnostic LEDs #4, #5, #6, and #7. The lower nibble bits are represented

by Diagnostics LEDs #0, #1, #2, and #3. Given the bit is set in the upper and lower

nibbles, then corresponding LED is lit. If the bit is clear, corresponding LED is off.

The Diagnostic LED #7 is labeled as “MSB”, and the Diagnostic LED #0 is labeled with

“LSB”.

In the following example, the BIOS sends a value of ACh to the diagnostic LED decoder.

The LEDs are decoded as follows.
