Installing or Replacing Processor(s) WARNING If the server has been running, any installed processor and heatsink on the processor board(s) will be hot. To avoid the possibility of a burn, be careful when removing or installing server board components that are located near processors. CAUTION Processor must be appropriate: You may damage the server if you install a processor that is inappropriate for your server. Make sure your server can handle a newer, faster processor (thermal and power considerations). If you are adding a second processor to your server, the second processor must be compatible with the first processor (within one stepping, same voltage, same speed). The system Sensor Data Records (SDR) must be reprogrammed every time that the processor configuration is changed. If you are adding a processor, or permanently removing a second processor, you must reprogram the SDR. Failure to reprogram the SDR may allow critical system failures to occur without an appropriate Telco alarm. Failure to recognize an alarm condition could result in loss of data or damage to equipment ESD and handling processors: Reduce the risk of electrostatic discharge (ESD) damage to the processor by doing the following: (1) Touch the metal chassis before touching the processor or server board. Keep part of your body in contact with the metal chassis to dissipate the static charge while handling the processor. (2) Avoid moving around unnecessarily. Retention Mechanism (RM): In 2U and greater chassis, use the RM brackets that ship with the chassis, not the RM that ships with the processor kit. Installing Processors 1. Raise the locking bar on the socket. Figure 11-8. Raising the Locking Bar OM14132 2. Observe the triangular symbols on the socket and on the processor. Orient the processor such that the triangular symbols are aligned. 3. Aligning the pins of the processor with the socket, insert the processor into the socket. Ensure that the pins are fully inserted and that the processor is flush against the socket. 98 Chapter 8

Installing or Replacing Processor(s)
WARNING
If the server has been running, any installed processor and heatsink on the
processor board(s) will be hot. To avoid the possibility of a burn, be careful when
removing or installing server board components that are located near processors.
CAUTION
Processor must be appropriate: You may damage the server if you install a processor that is
inappropriate for your server. Make sure your server can handle a newer, faster processor
(thermal and power considerations). If you are adding a second processor to your server, the
second processor must be compatible with the first processor (within one stepping, same
voltage, same speed).
The system Sensor Data Records (SDR) must be reprogrammed every time that the processor
configuration is changed. If you are adding a processor, or permanently removing a second
processor, you must reprogram the SDR. Failure to reprogram the SDR may allow critical
system failures to occur without an appropriate Telco alarm. Failure to recognize an alarm
condition could result in loss of data or damage to equipment
ESD and handling processors: Reduce the risk of electrostatic discharge (ESD) damage to the
processor by doing the following: (1) Touch the metal chassis before touching the processor or
server board. Keep part of your body in contact with the metal chassis to dissipate the static
charge while handling the processor. (2) Avoid moving around unnecessarily.
Retention Mechanism (RM): In 2U and greater chassis, use the RM brackets that ship with
the chassis, not the RM that ships with the processor kit.
Installing Processors
1.
Raise the locking bar on the socket.
Figure 11-8.
Raising the Locking Bar
OM14132
2.
Observe the triangular symbols on the socket and on the processor. Orient the processor such that the
triangular symbols are aligned.
3.
Aligning the pins of the processor with the socket, insert the processor into the socket. Ensure that the
pins are fully inserted and that the processor is flush against the socket.
