Removing and Replacing the Processor Board Assembly
The processor board assembly holds one or two dual-core Itanium processors and is located beneath
the disk drives and memory carrier assembly in the bottom service bay. The processor board is
mounted onto a removable carrier tray which is retained in the service bay by a hinged access
door.
WARNING! Ensure that the system is powered off and all power sources have been disconnected
from the server prior to performing this procedure.
Voltages are present at various locations within the server whenever an AC power source is
connected. This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to follow
ESD safety precautions can result in damage to the server.
