Processor socket technology
Itanium processor 9500 series uses a processor socket technology called Land Grid Array. The processor package
designs no longer have pins. Instead, the processor package has pads of gold-plated copper that touch processor socket
pins on the motherboard.
Technicians must be careful when installing processors to avoid damaging the delicate processor socket pins. If
installing a new CPU field-replaceable unit (FRU), first install the Ararat-II/processor assembly through the processor
socket guiding posts, followed by the heat sink installation. This is a simple procedure without any tools (figure 6).
