About this task
To avoid potential danger, make sure to read and follow the safety information.
Attention:
• Read "Installation Guidelines" on page 43
you work safely.
• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-
sensitive components in their static-protective packages until installation, and handling these devices with
an electrostatic-discharge wrist strap or other grounding system.
• Each processor socket must always contain a cover or a PHM. When removing or installing a PHM,
protect the empty processor sockets with a cover.
• Do not touch the processor socket or processor contacts. Processor-socket contacts are very fragile and
easily damaged. Contaminants on the processor contacts, such as oil from your skin, can cause
connection failures.
• Do not allow the thermal grease on the processor or heat sink to come in contact with anything. Contact
with any surface can compromise the thermal grease, rendering it ineffective. Thermal grease can damage
components, such as the electrical connectors in the processor socket.
• Remove and install only one PHM at a time. If the system supports multiple processors, install the PHMs
starting with the first processor socket.
Notes:
• Depending on the configuration, the processors require different types of heat sink.
1. The front processor (processor 1) always requires a standard heat sink.
2. For the rear processor (processor 2):
– with TDP lower than 250 watt: requires a 2U standard heat sink.
– with TDP higher than 250 watt: requires a 2U performance heat sink.
• The heat sink, processor, and processor carrier for your system might be different from those shown in the
illustrations.
• PHMs are keyed for the socket where they can be installed and for their orientation in the socket.

have the same speed, number of cores, and frequency.
• Before you install a new PHM or replacement processor, update your system firmware to the latest level.
See "Update the firmware" on page
Firmware and driver download: You might need to update the firmware or driver after replacing a
component.
